DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game sound device used for a game machine such as a pachinko machine and a slot machine.

[0002]

2. Description of the Related Art FIG. 6 shows a game sound apparatus disclosed in Japanese Patent Application Laid-Open No. 10-137394. In FIG. 6, 10
1 is a lower plate device, 102 is a ball receiving port of the lower plate device 101, 1
03 is a cover provided above the ball receiving port 102,
Reference numeral 104 denotes a slit formed in the cover 103, reference numeral 105 denotes a bass-reflex-type speaker housing arranged on the back side of the cover 103, and reference numeral 106 denotes a low-frequency speaker built in the speaker housing 105. And the speaker 10
The sound No. 6 is emitted to the front side through the slit 104.

[0003]

However, in the conventional example, the sound of the loudspeaker 106 is output from above the lower plate device 101 to the front side, that is, the sound of the loudspeaker 106 is transmitted to the game machine frame provided with the lower plate device 101. It is a structure to discharge to the front side. Therefore, it is necessary to use a large-capacity speaker box or a large-diameter speaker in order to increase the auditory sound pressure and generate a powerful sound. It is difficult to adopt this system because of the arrangement of components in a ball payout system such as a prize ball or a lending ball to the front side or a wiring system from the back side of the gaming machine frame to an electric component provided on the front side.

Accordingly, the present invention provides a game sound apparatus capable of reproducing powerful sound without increasing the size of a speaker box or a low-range speaker.

[0005]

According to the present invention, a speaker unit provided on a game machine frame so as to emit a sound on the front side to the front side of the game machine frame is provided on the rear side of the speaker unit. The back load horn that emits the sound of the to the front of the gaming machine frame is provided. Therefore, according to the present invention, the sound on the back side is guided and emitted to the front side of the gaming machine frame by the back load horn, so that the sound is emitted from the back side of the speaker unit to the front side of the gaming machine frame via the back load horn. Due to the synergistic effect of the sound emitted and the sound emitted from the front side of the speaker unit to the front side of the gaming machine frame,
Even without increasing the size of the speaker box or the bass speaker, it is possible to reproduce a powerful sound by increasing the audible sound pressure. In the present invention, the position where the speaker unit is provided is on the front side of the gaming machine frame, and the backload horn is provided on the rear sound outlet of the speaker unit and on the front side of the gaming machine frame. An overflow ball passage for guiding a ball overflowing from the dish device to a ball receiving port of a lower dish device provided on the front side of the gaming machine frame, and a rear sound passage connecting the rear sound outlet and the overflow ball passage. If it is formed by, the sound on the back side of the speaker unit is emitted to the front side of the gaming machine frame from the ball receiving port of the lower dish device, and there is also an effect that the ball rides on the sound and comes out to the lower dish device It becomes possible, and the playability can be improved by co-starring the sound and the ball. Further, in the present invention, if the rear sound path is formed by the rear plate provided with the front frame and the ball gutter forming the overflow ball path fixed thereto, the rear sound path can be formed by the existing sound path. It is a structure using a rear plate and a ball gutter, and a dedicated installation space for forming a rear sound passage is not required, and the depth of the device can be reduced. Further, in the present invention, if the speaker unit outputs a sound having a reproduction resonance frequency determined by the length of the back load, bass sounds of a specific pitch can be particularly emphasized. In the present invention, if the speaker unit is fitted to the speaker attachment portion provided on the gaming machine frame, the speaker unit can be easily attached or replaced.
