Claims

[Scope of utility model registration request]

(1) Sound reproduction that includes a microphone that converts sound pressure into a predetermined transmission signal, a transmission path that transmits the transmission signal, and a speaker that amplifies the signal transmitted via this transmission path and reproduces it as a sound wave. In a toy, a microphone is provided with a movable plate parallel to the vibration direction of a part of the diaphragm that transmits sound pressure, and a slit is bored in this movable plate, and a light source is connected to both sides of the movable plate through the slit. The light-receiving end of an optical fiber is placed opposite to the light-receiving end of the optical fiber, and the sound pressure is directly converted into an optical signal. A sound reproduction toy characterized by being configured to perform.

(2) The sound reproducing toy described in claim 1 of the utility model registration is provided with a semiconductor integrated circuit such as a microprocessor that stores and stores a programmed melody, and is configured to output the programmed melody from a spooker. A sound reproduction toy.
