Abstract: PURPOSE:To reduce sound volume to a proper level so that a PACHINKO (Japanese pinball game) hall is not noisy by attaching a microphone to a machine, and providing inside the PACHINKO machine a noise level regulating circuit to which output signals of the microphone are input and which outputs signals in response to inputs of more than set level. CONSTITUTION:The electric circuit of a generating device for a sound indicating a prize ball consists of an electronic sound generating circuit 32, a noise level regulating circuit 33, and a servo circuit 3A and the noise level regulating circuit 33 has a microphone 21, a flat amplifier 38, and an audibility compensating circuit 39, all connected thereto, and is so wired that sound volume more than a set phone is amplified by the audibility compensating circuit 39 and input to the servo circuit 34 located at the next stage. In this case, a synthetic sound around the device is input to the microphone 21 and an informing sound whose sound volume level is proportional to the output of the noise level regulating circuit 33 is generated from the generating circuit. Sounds of excessively high level are therefore reduced to proper sound volume level whereby a player can enjoy a PACHINKO game comfortably.
