Embodiment Construction

[0031] 1. Refer to the attached figure 1 The main microphone of the present invention is composed of pickup (MIC), preamplifier (AMP1), codec circuit (CODEC), output amplifier (AMP2), digital signal processor (DSP), memory (MEM), FM wireless receiver Device (REC), FM wireless transmitter (TRS), video encoder (VEN), main controller (MCU) and power supply module (PWR).

[0032] 2. Refer to the attached figure 2 The recording function of the microphone is composed of a pickup (MIC), a codec (CODEC), a digital signal processor (DSP), an animation processing (Flash), and a speaker. Sampling of the sound signal coming from the microphone. Each sample point is represented by a 16-bit signed number. We use adaptive incremental pulse code modulation (Adaptive Differential PulseCode Modulation) method to compress it. After compression, each sample point only needs 4 bits to store.

[0033] Adaptive incremental pulse code modulation (ADPCM) is an improved incremental modulation met...
