[0002]
[Prior art]
Since the speaker of a conventional ball game machine has a certain size, a large number of speaker holes are perforated at a predetermined position of a plate member in which an upper plate and a lower plate are integrally formed, and on the back side thereof. It was fixed. In the prior art disclosed in Japanese Patent Laid-Open No. Hei 3-139999, there is a speaker device that employs a piezoelectric speaker to reduce the weight and size.
[0003]
However, in the above prior art, only one speaker is installed in a locally limited place, that is, a position corresponding to the left side of the player's belly, so that the acoustic effect is not sufficient, lack of realism, etc. There was still a problem that it was not enough. Further, even in the case of a piezoelectric speaker, there are drawbacks that the structure is complicated and the mounting work is complicated, such as being housed in a plastic case or the like, or having a control base attached integrally.
[0004]

DETAILED DESCRIPTION OF THE INVENTION
Next, in order to further clarify the present invention, a bullet ball game machine 1 according to a first preferred embodiment will be described with reference to FIGS. First, as shown in FIG. 2A, the piezoelectric speaker 3 having the characteristic configuration of the present embodiment is provided integrally or detachably on a glass frame 10 attached to the front frame 9 (see FIG. 1). It is what has been. This glass frame 10 is obtained by attaching a plastic frame 10b to the periphery of a rectangular glass plate 10a. The piezoelectric speaker 3 is mounted in close contact with the surface (player side) of the glass plate 10a constituting the glass frame 10. The piezoelectric speaker 3 is formed of, for example, a transparent polymer piezoelectric polymer sheet. For detailed shapes, structures, materials, and the like, refer to Japanese translations of PCT publication No. 4-501046 and Japanese Utility Model Publication No. 1-44265. The glass frame 10 is mounted on the front frame 9 so that the piezoelectric speaker 3 side faces the player side. As a modification of the glass frame 10, as shown in FIG. 2B, the piezoelectric speaker 3 may be mounted at a predetermined interval in parallel with the glass plate 10a. The piezoelectric speaker 3 may be held by a reinforcing plate (not shown). The piezoelectric speaker 3 is connected to an amplifier 30 (see FIG. 5) with a lead wire (not shown). According to the ball game machine 1 configured in this manner, the vibration of the piezoelectric speaker 3 can ensure improvement in sound quality as well as sufficient sound output comparable to a dynamic speaker. In particular, since the entire air on the front side of the front frame 9 vibrates and a sound is generated from the front of the player's eyes, a completely different acoustic effect can be expected. Further, the collision sound between the game ball flowing down and the obstacle nail on the game board 2, the glass plate 10a, etc. is drowned out, and the game can be played comfortably.
[0014]
In addition, other different modifications of the glass frame 10 include those shown in FIG. 2C and FIG. 3, which are slightly different in configuration from those described above. That is, the piezoelectric speaker 3 is composed of the piezoelectric vibrator 5 and the vibration plate 7, and the vibration plate 7 is installed on the entire front surface of the glass plate 10a with a predetermined distance from the glass plate 10a. The piezoelectric vibrator 5 is fixed to the back side of the diaphragm 7 by an appropriate number of adhesives or the like. In this case, the piezoelectric vibrator 5 can employ various types such as a bimorph type piezoelectric element, a unimorph type piezoelectric element, and a ceramic type piezoelectric element as an example. The diaphragm 7 is a transparent foam resin plate and is bonded to the piezoelectric vibrator 5. As a result, the piezoelectric vibrator 5 and the diaphragm 7 vibrate, thereby producing the same effect as described above.
[0015]
When a bimorph type piezoelectric element is employed, as shown in FIG. 3, the piezoelectric vibrator 5 has piezoelectric elements 52 and 53 installed on the front and back surfaces of a diaphragm 51 that also serves as an electrode, and electrode plates 54 and 55 installed on the surface thereof. A bimorph type piezoelectric vibrator having the above structure is used. The lead wires 56 to 58 are connected to the diaphragm 51 and the electrode plates 54 and 55 so that AC power is supplied from the power supply circuit 11 described later. In such a configuration, when an AC voltage is applied to the electrode plates 54 and 55 of the piezoelectric vibrator 5, the piezoelectric element 53 contracts when the piezoelectric element 52 expands, while the piezoelectric element 53 expands when the piezoelectric element 52 contracts. The piezoelectric vibrator 5 vibrates. In place of the piezoelectric vibrator 5, a piezoelectric ceramic such as PZT may be used. In this case, the area is about 1 cm square, the thickness is less than 1 cm, and a lightweight and compact structure can be obtained.

That is, as indicated by the dotted line in FIG. 4, the piezoelectric speaker 61 is the normal symbol operating gate 28a, the piezoelectric speaker 62 is the normal symbol operating gate 28b, the piezoelectric speaker 63 is the entrance 6a, the piezoelectric speaker 64 is the entrance 6b, and the piezoelectric speaker. 65 is arranged in the front portion of the start winning opening 19. The piezoelectric speakers 61 to 65 are integrally formed to constitute a single transparent sheet. In addition, the electronic control device 15 described later is arranged on the surface of the game board in response to the operation of the parts of the game board, such as the piezoelectric speaker 65 ringing in response to the ball entering the start winning opening 19. The piezoelectric speaker is configured to ring. Thereby, there exists an effect that a preference increases. Note that the piezoelectric speakers 61 to 65 may be configured to be attached to a transparent sheet. In this case, the piezoelectric speaker can be easily added or changed.
