TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coupler device having an acoustic coupler function of transmitting / receiving information via a telephone line using a telephone handset (receiver) as connection means for electroacoustically converted data. .
[0002]
[Prior art]
Since such a coupler device is acoustically connected to the handset of the telephone, the coupling with the handset must be performed reliably and well in order to reduce the influence of ambient noise. However, since there are various types of handset handsets, it is necessary to provide a coupler device that can be adjusted and coupled according to each type. Therefore, conventionally, various configurations of acoustic coupler structures have been proposed.
[0003]
FIG. 14 is a diagram schematically illustrating an example of a conventional acoustic coupler structure provided in a so-called portable terminal device. In the same figure, 51 is an arm portion, 52 is a slide plate, 53 is a support body containing a microphone 53a, 54 is a torsion spring, 55 is a speaker, 56 is a lock claw, 57 is a main body of a portable terminal device, and 58 is a telephone. Handset. FIG. 7A shows a state at the time of storage, and FIG. 7B shows a state at the time of use. Both figures are drawn so as to compare the positional relationship with the handset 58.
[0004]
In order to set from the storage state of FIG. 7A to the use state of FIG. 7B, the support 53 is manually moved to the left in the figure, and is released from the main body 57 to release the lock claw 56. Then, the arm 51 and the support 53 hop up about the rotation shaft 51a by the function of the torsion spring 54. Then, according to the pitch between the earpiece 58a and the mouthpiece 58b of the handset 58 to be used, the slide plate 52 is adjusted and moved to the left and right in the figure, and the support 53 is brought into contact with the earpiece 58a, The mouthpiece 58b is placed so as to cover the upper side of the speaker 55, and is closely connected.
[0005]
At this time, since the arm portion 51 and the support body 53 are formed of an elastic member, the arm body 51 and the support body 53 are appropriately curved, and the support body 53 is brought into close contact with the earpiece 58a with an appropriate pressure, so that the influence of external noise is reduced. You. The speaker 55 is fixed at a predetermined position on the main body 57. In this case, the structure is not in close contact with the mouthpiece 58b. This is because the transmitting side is rarely affected by external noise. Finally, when transmission or reception is completed, the slide plate 52 is moved to the right in the figure, and the arm portion 51 and the support 53 are fixed to the main body 57 by the lock claws 56. State.
[0006]
Further, as another example, as described in Japanese Utility Model Laid-Open No. Sho 59-178727, a receiving unit having a receiving acoustic coupler is detachably attached to a main body having a transmitting acoustic coupler attached thereto. A data terminal device is disclosed. Alternatively, as described in Japanese Patent Application Laid-Open No. 62-200951, there is disclosed an acoustic coupler having a configuration in which an electro-acoustic transducer is supported at both ends of a telescopically extensible rod and is pressed against a handset. ing. Further, as described in Japanese Utility Model Publication No. 3-6055, the mouthpiece receiver and the earpiece receiver are connected by a leaf spring, and these can be fixed at an arbitrary position so that they can be fitted to the handset. A handset receiving device for an acoustic coupler is disclosed.
[0007]
[Problems to be solved by the invention]
However, in the configuration as shown in FIG. 14, each time the receiver is set to the state of use, the receiver is a receiver according to the pitch of the earpiece 58a and the earpiece 58b of the handset 58 to be used. It is necessary to adjust the pitch between the support 53 and the speaker 55 which is the mouthpiece receiver. Usually, the handset used is often limited to a public phone or a user's own mobile phone, but in that case it is very inconvenient considering that the pitch must be adjusted one by one. . It is desirable that once the pitch is adjusted, it can be used as long as the shape of the handset does not change.
[0008]
Further, since the arm portion 51 and the support 53 shown in the figure are formed of an elastic member, the curved state during use is maintained as it is, and a so-called habit may be formed. In addition, it becomes difficult, and it protrudes from the main body 57 in the stored state. Further, even in the configurations described in the above publications, it is necessary to further improve the operability, the storability and the like in the same manner.
[0009]
Furthermore, portable terminal devices for creating, sending and receiving e-mails, which are becoming popular in recent years, are designed for the purpose of being easily and easily used in places other than the original business place, and are easy to carry and compact. There is a demand for simplicity of device operation during use, assurance of setting reliability and reliability, and maintenance of performance of the transmitting / receiving section (here, the acoustic coupler portion) when not in use. However, such portable terminal devices are usually mixed with other office supplies and documents and put in a bag or the like, and often carried together. In severe cases, there are many factors that cause damage to the apparatus, such as collision with other hard office supplies.
[0010]
In particular, if the transmission / reception unit is damaged, it is fatal and the original function of the mobile terminal device is impaired. In addition, such a portable terminal device needs to use a public telephone or a telephone handset (receiver) provided at a destination or a portable telephone as a medium as a transmission / reception means. In addition to the characteristics, there are various types, and the pitch and shape of the mouthpiece and earpiece, which are the contact points of transmission and reception, are also various, so that a structure that can appropriately cope with them is required. To this end, an acoustic coupler structure serving as a transmission / reception contact point on the mobile terminal device side is a particularly important factor. Furthermore, it is also a very important factor that the acoustic coupler portion is not exposed to the exterior surface and has a structure that is hardly damaged.
[0011]
In view of the above problems, the present invention can flexibly and easily cope with handsets of telephones having various shapes and the number of adjustments for adjusting to the shape of the handsets. It is an object of the present invention to provide a coupler device which can minimize the number of the components and which is hardly damaged by external force.
[0012]

And a arm portion supporting the microphone case, the microphone case and the arm portion respectively engage with hooks provided at both ends of the coil spring, and are connected by the coil spring. I do.
[0013]
Then, a lead wire extending from the microphone is inserted through the inner diameter space of the coil spring and laid from the microphone case to the arm portion.
[0014]
Further, a microphone rubber that is in close contact with the earpiece of the handset is fitted around the microphone case. Further, a space is provided inside the microphone rubber.
[0015]
In addition, a storage portion for storing the earpiece receiving portion is provided, and the earpiece receiving portion hops up from the storage portion in use. Further, the storage unit may be provided with a projection that comes into contact with the microphone case when the earpiece receiver is stored.
[0016]
Further, the mouthpiece receiver is configured to be slidable so as to adjust a pitch between the mouthpiece receiver and the mouthpiece receiver. Furthermore, a configuration is provided in which a single sheet member or a plurality of sheet members overlapping each other having different lengths in the sliding operation direction are provided to follow the sliding operation of the mouthpiece receiving section and to shut off the inside and outside of the apparatus main body. And A bent portion is formed at both front and rear ends of the sheet member in the sliding operation direction. The sheet member is made of a resin material.
[0017]
The mouthpiece receiving portion has a concave surface. Further, a projection is provided on the surface of the mouthpiece receiving portion.
[0018]

[0022]
Further, in order to adjust the pitch between the earpiece receiver 5 and the mouthpiece receiver 6 in accordance with the pitch between the earpiece and the mouthpiece of the telephone handset, the mouthpiece receiver 6 is connected to the main body 10. Can be slid in the longitudinal direction. Here, when the earpiece receiving portion 5 is stored and the mouthpiece receiving portion 6 is exposed, the exposed portion is made of only a hard resin material. The configuration of the coupler device based on these will be described later in detail.
[0023]
FIG. 4 is a perspective view showing a state where the earpiece receiver 5 has hopped up. When the hop-up knob 7 is operated toward the earpiece receiver 5, the earpiece receiver 5 rotates around the end of the main body 10 as shown in FIG. And hop-up so as to protrude from the end of the main body 10 in a direction away from the mouthpiece receiving portion 6. As a result, it becomes possible to set the handset of the telephone (not shown). The arrangement of the coupler device, the transmission key 1 and the indicator 2 in the main body 10 is not limited to the configuration of the present embodiment. Also, the configuration of the mobile terminal device is not limited to the configuration shown in the present embodiment.

[0025]
FIG. 6 is a longitudinal sectional view showing the assembled state of the earpiece receiving section 5, and FIG. 7 is a longitudinal sectional view showing the stored state. FIG. 8 is an exploded perspective view showing a component configuration of the earpiece receiving section 5.
[0026]
6 or 8, reference numeral 11 denotes a substantially ring-shaped microphone rubber which is a contact part with the earpiece, 12 denotes a substantially disk-shaped microphone case fitted around the inner periphery of the microphone rubber 11, and 15 denotes a lower surface of the microphone case 12. This is also a substantially disk-shaped microphone case. A substantially cylindrical casing 15a extending upward is provided at the center of the upper surface of the microphone case 15, and the substantially cylindrical microphone 14 is fitted therein. Note that the lead wire 16 extending from the microphone 14 is taken out of the cutout portion 15b of the casing 15a and inserted through the inside of the coil spring 17. The lead wire 16 is a shielded wire so as not to pick up external noise.
[0027]
On the upper surface of the microphone 14, a substantially disk-shaped microphone filter 13 for protecting the microphone 14 is provided, and these are sandwiched between the microphone cases 12 and 15 and attached. At this time, a hook 17 a provided at one end of the coil spring 17 is fitted and attached to the outer periphery of the casing 15 a of the microphone case 15, and the coil spring 17 is also sandwiched between the microphone cases 12 and 15. Finally, the microphone case 12 is fastened and fixed to the microphone case 15 with screws 25. The microphone 14 catches sound through a hole 12 a provided in the center of the microphone case 12.
[0028]
The microphone rubber 11 is a contact part with the earpiece as described above, and is a very important part for accurately and reliably transmitting data. Therefore, the microphone rubber 11 is flexible and does not deteriorate due to aging. A material that is easily processed by a mold, such as urethane rubber or silicon rubber, is used. As shown in FIG. 6, the microphone case 12 is attached to the microphone case 15 so that the microphone rubber 11 can be freely fitted to the microphone case 12 and can be easily removed and replaced when the microphone rubber 11 is damaged. The lower inner peripheral portion of the microphone rubber 11 is fitted into and fixed to a concave groove 15c formed around when assembled.
[0029]
At this time, an internal space 11a is formed between the microphone rubber 11 and the microphone case 12 all around the upper portion of the microphone rubber 11, thereby increasing the flexibility of the microphone rubber 11 and promoting the adhesion to the earpiece. Further, as shown in FIG. 7, in the present embodiment, a projection 27 is provided in the storage section D of the bottom cabinet 22 forming the housing C, and when the earpiece receiving section 5 is stored in the main body 10, the microphone case 12 is closed. The microphone rubber 11 is prevented from contacting the bottom cabinet 22 by having a configuration in which the projection 27 is brought into contact with the bottom cabinet 22. This can prevent the microphone rubber 11 from being deformed even when the stored state is kept long.
[0030]
Referring again to FIG. 6 or 8, reference numerals 20 and 21 denote substantially thick plate-like arms attached to the bottom cabinet 22, and a pair of fixing parts 21 a provided at one end of the arm 21 have a pair of fixing parts 21 a, respectively. The flip springs 18 are fitted, and these are sandwiched between the arms 20 and 21 from above and below, and attached and fixed.
[0031]
At this time, a hook 17b provided at the other end of the coil spring 17 is fitted and attached to an outer periphery of a substantially columnar projection 21b extending upward between a pair of fixing portions 21a of the arm portion 21, and the coil spring 17 is also mounted. It is sandwiched between the arm portions 20 and 21. The lead wire 16 passing through the inside of the coil spring 17 is passed through one flip spring 18, taken out to the outside, and guided to the inside of the bottom cabinet 22. Finally, the arm part 20 is fastened and fixed to the arm part 21 by the screw 26.
[0032]
As shown in FIG. 8, a substantially prism-shaped projection 18a extends from one end of each of the flip springs 18, and this is inserted into a square hole 22a formed on the left and right of the storage section D at the end of the bottom cabinet 22, respectively. By being inserted and fitted, the flip spring 18 has a function as a rotation axis of the earpiece receiver 5. When the flip spring 18 relatively rotates the main body and the projection 18a by an external force, the flip spring 18 attempts to return to its original state by an elastic force when the rotation amount is up to a predetermined angle. It is a commercially available component (manufactured by Kato Spring Co., Ltd.) having a structure that attempts to rotate by a certain angle by elastic force, and has been frequently used in recent years for a cover of a mobile phone.
[0033]
Further, in order to reliably maintain the positional relationship between the earpiece 8a of the handset 8 and the earpiece receiving part 5 as shown in FIG. 5, a non-slip rubber 19 which has a large frictional resistance to the earpiece and prevents slippage is provided. Is attached to the upper surface of the arm unit 20. As a result, the screw 26 can be covered and concealed, so that the appearance is improved and the user cannot easily disassemble it, which is also effective for maintaining the function of the apparatus.
[0034]
As shown in FIG. 8, an arm 23 slidably fitted to the back surface of the bottom cabinet 22 and having a function of hopping up the earpiece receiver 5 is provided. The hop-up knob 7 communicates with the hop-up knob 7 and has a substantially U-shape. The operating point 23a at the free end of the hop-up knob 7 acts on the earpiece receiver 5 by operating the hop-up knob 7, and the hop-up knob 7 It is something to be up. In a state where the arm 23 is attached, the hop-up knob 7 is in a state of protruding outside from a relief hole 22b provided on the surface of the bottom cabinet 22.
[0035]
Incidentally, the microphone cases 12, 15 and the arm portions 20, 21 are formed of a thermoplastic resin. The hooks 17a and 17b formed at both ends of the coil spring 17 have an effective shape for preventing the earpiece receiving portion 5 from rotating freely. On the other hand, the coil spring 17 has a function of allowing the earpiece receiving portion 5 to bend and move flexibly and flexibly, and as described above, the transmission for signal transmission is performed in the inner diameter space of the coil spring 17. Since the lead wire 16 which is a conductive wire as a member can be passed through, the protection is possible and the wire processing is very easy, so that a highly reliable and small device can be provided. .
[0036]
FIG. 9 is an explanatory diagram of the mechanism by which the earpiece receiver 5 hops up. (A) of the figure is a plan view thereof, and (b) is a side view thereof. As shown in the drawing, when the coupler apparatus according to the present embodiment is not used, the earpiece receiving section 5 is normally housed in the bottom cabinet 22, and the hop-up knob 7 and the arm 23 communicating therewith are provided with a spring. 24 is normally slid rightward in the figure, and its action point 23a is not in contact with the arm portion 21. When the hop-up knob 7 is moved to the left in the drawing at the time of use, the arm 23 also slides to the left as shown by the arrow in the drawing, and the action point 23 a comes into contact with the arm 21.
[0037]
Further, by the function of the slope forming the action point 23a, the arms 20, 21 indicated by broken lines in FIG. 9B are lifted, and the earpiece receiver 5 is pulled by using the flip spring 18 as a rotation axis (flip hinge). Rotate counterclockwise in the figure. In the case of the present embodiment, when the earpiece receiver 5 is opened by about 15 degrees with respect to the bottom cabinet 22, the earpiece receiver 5 is further automatically rotated by 120 degrees due to the characteristics of the flip spring 18, that is, the earpiece receiver 5 is turned to the bottom. The cabinet 22 is opened up to 135 degrees.
[0038]
Further, it is possible to open up to 180 degrees as shown by the solid line depending on the load when the earpiece (not shown) is set. At this time, a biasing force that rotates clockwise acts on the contrary due to the characteristics of the flip spring 18. When the earpiece receiver 5 is manually returned so as to be within about 15 degrees with respect to the bottom cabinet 22 at the time of storage, the storage state shown in FIG.
[0039]
As a characteristic of the flip spring, a predetermined rotation angle required until the flip spring itself is further rotated automatically from a steady state of the flip spring itself by an external force is actually about 30 degrees. There is a margin to rotate clockwise further by -15 = 15 degrees from the stored state in FIG. As a result, during storage, the earpiece receiving section 5 is abutted and fixed to the bottom cabinet 22 while being prevented from being lifted while being urged. Note that the predetermined rotation angle of the flip spring is not limited to the present embodiment, but may be selected for its characteristics or for adjusting the relative angle when the flip spring is attached to the bottom cabinet 22 or the arm 21. Can be changed.
[0040]
Furthermore, the present invention is not limited to the configuration using such a flip spring. For example, the earpiece receiving portion 5 is always biased in a hop-up direction, and when stored, some engaging portion works to hold it. However, it is of course possible to adopt an orthodox configuration in which the engagement is released during use to hop up and stand by. Alternatively, a configuration using a simple method, such as raising the earpiece receiver 5 directly by hand, may be used.
[0041]
FIG. 10 is an exploded perspective view showing the mouthpiece receiving section 6 and the components around it. As shown in FIG. 5, in order to reliably maintain the positional relationship between the mouthpiece 8b of the handset 8 and the mouthpiece receiving part 6 as shown in FIG. Anti-slip rubber 31 is attached to the step 22c on the bottom cabinet surface. The mouthpiece receiving portion 6 (more precisely, a protrusion 36a of a speaker housing 36 described later) is inserted into each of these portions, and provided with slidable slots 31a and 22d, respectively.
[0042]
Reference numeral 37 denotes a substantially disk-shaped speaker, which has a function of converting an electric signal based on the created data into an audio signal. The lead wire 32 extends laterally from the speaker 37. A substantially flat plate-like member 36 located above the speaker 37 is a speaker housing, and a substantially disk-shaped protrusion 36a is provided on the upper surface of the speaker housing. . The upper surface of the protrusion 36a is concave so that the mouthpiece 8b is easily stabilized when the mouthpiece 8b is closely joined, and a large number of holes 36b for emitting sound from the speaker 37 are formed. Note that, depending on the shape of the mouthpiece 8b of the target telephone, the upper surface of the protrusion 36a does not necessarily need to be concave, and may be a flat or convex surface in a corresponding form.
[0043]
Further, here, a plurality of protrusions 36c are arranged in a short linear shape substantially perpendicular to the sliding direction of the mouthpiece receiving portion 6, and these have a height so as not to protrude above the upper end of the protrusion 36a. Is suppressed. Since the projection 36c has an effect of preventing the finger from slipping when the mouthpiece receiver 6 is manually slid, the operability at the time of setting the handset can be improved. The shape of the protrusion 36c is not limited to the shape in the present embodiment, but may be various shapes such as a round shape and a square shape, and may be any as long as it has an effect of preventing the finger from slipping.
[0044]
Further, the speaker housing 36 is supported from both side surfaces and the lower surface of the figure by long plate-shaped speaker pressing plates 38 and 39, and is attached to the back surface of the bottom cabinet 22 by screws 40. At this time, a lock concave portion 38a is continuously formed on the side surface of the speaker pressing plate 38 so as to face a lock convex portion 36d provided on one side surface of the speaker housing 36, and the lock convex portion 36d is formed on any of these. Is engaged, so that the speaker housing 36 and the mouthpiece receiving portion 6 are fixed at an arbitrary sliding position.
[0045]
The configuration for adjusting the slide position is not limited to the configuration of the present embodiment. For example, the arrangement relationship between the lock convex portion and the lock concave portion may be exchanged, and the use of frictional force may be used. It may be configured such that the adjustment can be performed in a stepless manner. Further, according to the configuration for adjusting the slide position of the mouthpiece receiving section 6 as described above, particularly when the handset to be used is limited, once the adjustment is performed, the slide position is maintained from the next time. It is convenient because it can be used.
[0046]
Further, as shown in the figure, between the speaker housing 36 and the bottom cabinet 22, hide seats 33, 34, 35 are disposed so as to overlap. This is for shutting off the inside and the outside of the device so that the front side and the back side of the cone portion of the speaker 37 do not acoustically interfere with each other. Each of the hide seats is provided with elongated holes 33a, 34a, and 35a through which the protrusions 36a of the speaker housing 36 are inserted and slidable.
[0047]
Further, the length of each hide sheet in the sliding direction is gradually reduced in a stepwise manner, and furthermore, bent portions 33b, 34b, 35b are provided at the front and rear ends, respectively. Thus, in a state where the respective hide sheets are overlapped, the relative sliding stroke is regulated within the range of the difference in length by the contact between the bent portions, and the speaker housing 36, that is, the mouthpiece Irrespective of the position to which the receiving portion 6 is slid, the inside of the device always has the effect of being closed to the outside. Further, according to such a bent portion, an effect of increasing the strength of each hide sheet can be obtained. However, the configuration in which the bent portion is provided is not limited. For example, a configuration in which a contact portion that regulates a slide stroke is provided in each slide sheet may be used.
[0048]
The number of the hide sheets is not limited to the three sheets described in the present embodiment, and an effective number of sheets that can achieve the effect reliably and are selected as needed. For example, as shown by a two-dot chain line in the same drawing, there may be a case where a hide sheet group 41 having a different length is further inserted step by step between the respective hide sheets. As a material of the hide sheet, a resin material such as a PET material or a PVC material which is not affected by static electricity and is lightweight is preferable. In any case, a configuration is required that smoothly follows the sliding movement of the speaker housing 36 and can reliably shut off the inside and the outside of the device.
[0049]
In this sense, the configuration is not limited to the configuration in which the hide sheets are overlapped as in the present embodiment. For example, a configuration in which a shutter is provided to perform winding up and rewinding, or a configuration in which a bellows-shaped object is expanded and contracted may be used. It is good. Alternatively, it is also possible to adopt a configuration in which only one hide sheet is slid, but in this case, the device becomes extra long by the stroke.
[0050]
FIG. 11 is a diagram showing a change in the sliding position of the mouthpiece receiving unit 6 depending on the length of the handset 8 to be set. FIG. 7A shows the case where the handset 8 is the longest usable, that is, the case where the pitch between the earpiece 8a and the mouthpiece 8b is the longest with respect to the coupler apparatus of the present embodiment. FIG. 3 (b) similarly shows the shortest case. In either case, the earpiece receiver 5 is closely connected to the earpiece 8a, and the mouthpiece receiver 6 is sufficiently connected to the mouthpiece 8b. In this way, a flexible response is possible according to the length of the handset 8.
[0051]
FIG. 12 is a diagram showing differences in various dimensions depending on the shape of the handset 8. FIG. 1A shows a handset of a telephone mainly used in a home with an emphasis on fashionability, and FIG. 1B shows a handset of a business telephone or a public telephone handset mainly used in an office. FIG. 1C shows a mobile phone whose main body also serves as a handset. The pitch between the earpiece 8a and the mouthpiece 8b of each handset 8 is indicated by Pa, Pb, and Pc, respectively, and these have various dimensions. Also, the inclination angles α, α ′ and θ, θ ′ of the surfaces of the earpiece 8a and the mouthpiece 8b shown in FIGS. The coupler apparatus of the present embodiment is configured to be able to cope with various shapes of these handsets as much as possible.
[0052]
FIG. 13 is a perspective view schematically showing another example of the coupler apparatus. FIG. 1A shows a case where a mouthpiece receiving section 5 and a mouthpiece receiving section 6 are provided on the side surface of the main body 10. FIG. 2B shows a state in which the earpiece receiving part 5 and the mouthpiece receiving part 6 are taken out from the respective housing parts 5a, 6a provided at both ends of the main body 10, and the respective lead wires 5b, 6b are followed. A configuration for connecting to an earpiece and a mouthpiece (not shown) is shown. As described above, the form of the coupler device is not limited to the above-described embodiment, and various variations can be considered.
[0053]
Note that the sheet member referred to in the claims corresponds to the hide seat in the embodiment.
[0054]
【The invention's effect】
As described above, according to the present invention, it is possible to flexibly and easily respond to a handset of a telephone having various shapes, and to adjust the number of adjustments to match the shape of the handset. It is possible to provide a coupler device which can be reduced as much as possible and which is hardly damaged by external force.
[0055]
In particular, according to the first aspect, it is possible to provide an earpiece receiving portion which is flexible and capable of free movement, is excellent in durability and restoring force, and is easily brought into close contact with the earpiece due to the characteristics of the coil spring. Further, the rotation of the microphone case can be suppressed by the hooks provided at both ends of the coil spring.
[0056]
