[0006]
DETAILED DESCRIPTION OF THE INVENTION
1. Next, an electronic musical instrument according to an embodiment of the present invention will be described with reference to FIG.
In the figure, reference numeral 1 denotes a rear unit, which is formed in a trapezoidal flat plate shape. A battery pack 2 is detachable from the rear unit 1 and supplies power to each part of the electronic musical instrument. Reference numeral 4 denotes a left front unit, and reference numeral 6 denotes a right front unit, in which operators such as a plurality of switches operated by a user are arranged. Reference numerals 8 and 10 denote shoulder belts, each having one end coupled to the left front unit 4 and the right front unit 6 and the other end coupled to the back unit 1.
[0007]
Connectors 4a and 4b are provided at the upper and lower ends of the left front unit 4 in order to connect a sensor cable, and similar connectors 6a and 6b are provided at the upper and lower ends of the right front unit 6. . A cable 12 is embedded in the shoulder belt 8 and connects the left front unit 4 and the back unit 1. Similarly, the cable 14 is embedded in the shoulder belt 10 and connects the right front unit 6 and the back unit 1.
[0008]
An example in which this electronic musical instrument is mounted on a user is shown in FIGS.
In FIG. 2, reference numeral 22 denotes a left hand sensor unit that is attached to the user's left hand, and is connected to the connector 4 a of the left front unit 4 via the sensor cable 20. Reference numeral 26 denotes a left foot sensor unit attached to the user's left foot, which is connected to the connector 4b of the left front unit 4 via the sensor cable 24.
[0009]
Similarly, 32 is a right hand sensor unit attached to the user's right hand, and is connected to the connector 6 a of the right front unit 6 via the sensor cable 30. Reference numeral 36 denotes a right foot sensor unit 36 attached to the user's right foot, which is connected to the connector 6b of the right front unit 6 via the sensor cable 34.
[0010]
Next, a rear view and a bottom view of the rear unit 1 are shown in FIGS. In these drawings, reference numerals 40 and 42 denote spacers, which are each formed in a substantially rectangular shape with flexible plate portions 40a and 42a and fixed to the rear unit 1 along the center line of the plate portions 40a and 42a. The two discs 40b, 40c, 42b, and 42c. As a result, a slight distance is left between the back unit 1 and the user, and the user's sweat is prevented from entering the back unit 1.
[0011]
Reference numerals 44 and 46 denote rotating shafts for the shoulder belts 8 and 10, which protrude from the rear surface of the rear unit 1 and pivotally support the shoulder belts 8 and 10 (not shown). The protruding length of the rotating shafts 44 and 46 is slightly shorter than the protruding length of the spacers 40 and 42. Thereby, when the back unit 1 is mounted on the user, the rotation of the shoulder belts 8 and 10 is hardly hindered. Reference numeral 48 denotes a MIDI output terminal, and reference numeral 50 denotes an audio output terminal, which is provided on the bottom surface of the rear unit 1 and outputs a MIDI signal and an audio signal (musical sound signal) corresponding to the output value of each sensor unit.
[0012]
In this embodiment, since the back unit 1 is formed in a substantially flat plate shape, when the user wears this, the back unit 1 can be fitted to the back exactly. In addition, by appropriately distributing the weights of the rear unit 1 and the left and right front units 4 and 6, it is possible to obtain a fit that sticks to the body.
[0013]
In this case, rather than concentrating the mass on the shoulder belts 8 and 10, it is more stable to distribute the mass to the units 1, 4 and 6 as much as possible. That is,
"Total mass of units 1, 4 and 6> Total mass of shoulder belts 8 and 10"
It is desirable to set the mass so that
[0014]
2. Modifications The present invention is not limited to the above-described embodiments, and various modifications can be made as follows, for example.
(1) You may provide the other band which connects the said back unit 1, the left front unit 4, and the right front unit 6 along a user's trunk periphery. Thereby, since each unit is firmly fixed to the user, for example, when the user stands upside down or moves more violently, it is possible to prevent inconveniences such as disconnection of each unit.
[0015]
(2) Since the present invention divides an acoustic signal generating device such as an electronic musical instrument into at least one user back mounting part and at least one user front mounting part, the user back mounting part and the user front mounting part Any internal circuit configuration may be used. For example, only the power source may be provided in the user back surface mounting portion, and all other circuits may be provided in the user front surface mounting portion.
[0016]
(3) In the above embodiment, a small speaker may be provided on the upper surface of the rear unit 1 so that a musical sound signal output from the audio output terminal 50 is generated. Since the upper end of the rear unit 1 is relatively close to the user's ear, the user can sufficiently monitor the musical tone signal even when the reproduction volume of the speaker is low. This eliminates the need for an external sound system when rehearsing or the like.
[0017]
(4) In the above embodiment, a wireless transmitter that modulates and transmits the output MIDI signal or musical tone signal may be provided. Thereby, a MIDI signal or a musical sound signal can be transmitted wirelessly to an external sound source or sound system, and the degree of freedom of movement of the user is further improved.
[0018]
(5) In the above embodiment, the cables 12 and 14 are embedded in the shoulder belts 8 and 10, but it goes without saying that these may be disposed along the surface of the shoulder belts 8 and 10.
[0019]
(6) Although the said embodiment showed the example which used this invention for the electronic musical instrument, the acoustic signal generator of this invention is not limited to an electronic musical instrument. In addition, the acoustic signal and the cause signal also depend on the application, and are not limited to the musical tone signal or the MIDI signal.
For example, the present invention can be applied to a portable CD player. In this example, the acoustic signal is a CD playback audio signal, and the cause signal is a CD playback EFM signal or the like.
[0020]
In addition, the present invention may be applied to a transceiver or a cellular phone, in which case the acoustic signal is a demodulated signal of the received radio wave. Further, the present invention can be applied as an input device for a simulation game such as a ball game or a martial art that advances a game according to a user's movement. In this case, if the device of the present invention generates a hitting sound or the like according to the user's movement, the hitting sound is nothing but an “acoustic signal”.
[0021]
Here, the present invention can also be applied as a user-mounted unit that amplifies the detection signal of the sensor mounted on each part of the user and transmits the detection signal to the main body of a separate game machine. In this case, in the game machine main body, a hitting sound or the like is generated according to the detection signal of the sensor, and therefore the detection signal of the sensor is nothing but the “cause signal” that causes the generation of the acoustic signal.
[0022]
【The invention's effect】
As described above, according to the present invention, it is possible to stably attach each unit to a user even in the case of intense movement.
