Abstract

PROBLEM TO BE SOLVED: To reproduce an effective sound of good quality which is easy to follow by fixing a piezoelectric element type speaker to the inner surface of a sheet glass provided on the front surface of a Pachinko(Japanese pinball game) machine, and transmitting vibration of the speaker to the sheet glass to make the sound loud. SOLUTION: A glass frame 2, one side edge of which is pivoted on the front frame 1 of a Pachinko game machine by a hinge to be opened and closed, is so constructed that two sheet glasses 5, 6 are supported inside to form a gap 4, and a glass pressing piece 7 is provided on the upper edge of the glass frame 2. In this case, a piezoelectric element type speaker 12 is fixed to the inner surface of the front sheet glass 5 by an adhesive or the like, and connected to a voice output terminal of a game control board 11 provided on the back of a game board 8 through a through hole 14 bored in the glass pressing piece 7 and a through hole 15 bored in the game board 8 by a speaker cord 13. A voice signal of an effective sound or the like outputted from the game control board 11 is reproduce by the speaker 12, and the sheet glass 5 is used as a vibrating plate to make the sound easy to follow, so that a voice of a good sound quality can be generated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for reproducing sound such as sound effects in a pachinko game machine.

[0002]

2. Description of the Related Art In recent years, a pachinko gaming machine has a start winning port, a symbol change indicator and a large winning port on a game board, and when a hit ball wins in the start winning port, the symbol on the symbol change indicator changes. At the same time, when the symbols at the time of the stop are aligned with the predetermined symbols, the special game state (big hit) is established, and the operation of opening the special winning opening for a predetermined time or until a predetermined number of hit balls is won is performed for a predetermined cycle, so that the player has a great deal of time. So-called Seven-machines or so-called "rights" that provide profits are gaining in popularity. And in this kind of pachinko machine,
In order to further enhance the interest of the game, there is provided a speaker for emitting a sound effect when a hit ball wins a winning opening or a special game state occurs.

In a conventional pachinko gaming machine, a storage space is formed in a double structure with a bottom portion of an upper ball tray or a lower ball tray provided at a lower front portion of a front frame, and a speaker is stored in the storage space. Or JP-A-8-57144
As disclosed in Japanese Unexamined Patent Publication, a cylindrical storage portion for storing speakers is provided on the front of the waist plate portion of the mounting frame of the game board, and after storing the speakers in the storage portion, a protective cover is attached to the front surface. The speaker was supported and fixed.

[0004]

By the way, in the former of those described in the prior art, most of them are provided with a sound-transmitting hole at the bottom of the upper or lower ball dish, and are opposed to the sound-transmitting hole. Since the speaker is mounted downward, there is a problem that the sound effect emitted from the speaker is sent out toward the player's feet and is difficult to hear.

Also, in the latter case, since a front plate to which an upper ball tray is fixed is attached to the front of a protective cover for supporting and fixing the speaker, a state in which the front region of the speaker is closed by the front plate. Thus, there is a problem that the sound effect is stuck inside the pachinko gaming machine and a good sound effect cannot be obtained.

Further, in the latter case, the speaker and the protective cover for supporting and fixing the speaker are directly attached to the mounting frame of the game board, so that the work corresponding to the assembly line of the pachinko game machine is required. There is a problem that it takes time, and it is not easy to attach or replace the speaker.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to reproduce a high-quality sound effect that is easy to hear and to be easily installed without requiring a space. It is an object of the present invention to provide a sound reproducing device in a pachinko gaming machine which can reduce the manufacturing cost.

[0008]

For this purpose, a sound reproducing apparatus in a pachinko game machine according to the present invention has a piezoelectric element type speaker fixed to an inner surface of a plate glass provided on a front surface of the pachinko game machine, and the vibration of the speaker is reduced. The sound is transmitted to the sheet glass and is amplified.

[0009]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a pachinko gaming machine,
FIG. 2 is a longitudinal sectional view of a part thereof. In FIG. 1, reference numeral 1 denotes a front frame of a pachinko game machine, and 2 denotes a glass frame having one side edge 3 pivotally connected to the front frame so as to be opened and closed by a hinge. Inside the glass frame 2, as shown in FIG.
6 are supported so as to form a gap 4 of about 10 mm. Reference numeral 7 denotes a glass pressing piece provided on the upper edge of the glass frame 2. 8 is a game board (veneer board) provided with a large number of nails, winning holes, etc. on the front, 9 is a winning ball set cover provided on the back of the game board, 10 is a board case, and a game control is provided in the board case. A circuit board 11 is provided.

Reference numeral 12 denotes a piezoelectric element type speaker fixed to the inner surface of the front glass plate 5 with an adhesive or a screw or the like. Reference numeral 13 denotes a speaker cord connected to a terminal of the speaker. And through the through hole 14 opened in the glass holding piece 7, further through the through hole 15 opened in the game board 8, to the back of the game board 8 and connected to the audio output terminal of the game control board 11,
An audio signal such as a sound effect output from the game control board is reproduced by the piezoelectric element type speaker 12.

The piezoelectric element type speaker 12 is a piezoelectric element such as a crystal having a thickness of about 3 mm and a square of about 15 mm.
Two electrodes are provided, and a speaker cord 13 is connected to the electrodes. When an AC voltage such as an audio signal is applied to the electrodes, the electrode vibrates according to the frequency of the audio signal due to its piezoelectric effect, and the vibration is reduced. The sheet glass 5 transmitted to the sheet glass 5
The sound is reproduced on the front of the pachinko gaming machine by vibrating the air through the. By using the plate glass 5 as a diaphragm in this manner, a large vibration area can be secured, and low-frequency sound reproduction that cannot be performed by a conventional small speaker becomes superior and sound quality can be improved.

[0013] In this case, since the player facing the pachinko gaming machine can produce a sound directly from the front, it is easy to hear and the sound quality can be improved. It should be noted that a conventional small speaker and this audio reproducing device may be combined and used as a so-called two-way speaker.

[0014]

As described above, the sound reproducing apparatus in the pachinko game machine according to the present invention has the piezoelectric element type speaker fixed to the inner surface of the plate glass at the front of the pachinko game machine, so that sound such as sound effects can be reproduced. Even if the sound is reproduced from directly in front of the player and the noise due to the in-store broadcasting at the pachinko parlor or BGM is intense, the sound can be easily heard and the sound quality is improved. In addition, since it can be arranged in the gap between the inner surfaces of the sheet glass and requires no space at all, and is easy to mount, there are beneficial effects such as a reduction in manufacturing cost.
