I will do my own DIY.

The scheme is a voice record discharge circuit composed of HY560 is a simple recording circuit with a small volume, power saving, and does not require a tape. The working principle is shown in the following figure. The circuit is to achieve circuit function by applying a full electronic digital recording integrated circuit HY560, and the internal portion of HY560 contains: microphone amplifying circuit, automatic gain control circuit, mode / digital conversion circuit, digital / mode conversion circuit, static memory, logic control Components of circuits, audio amplifiers. When using, press SB1 (Recording Buttons), the sound signal will be accepted by the microphone B1, and converted into an electrical signal. After the transmission is amplified by the microphone, it is converted into a digital signal to store it in a static memory. When the button SB2 (playback button) is pressed, the stored digital recording signal is removed from the static memory. After the number / mode conversion circuit, the digital signal is converted into an analog signal (electrical signal), after the audio is magnificent, To drive the speaker to make a sound. In terms of component selection, the circuit components do not have special requirements and can be selected according to the circuit diagram.
