Description of drawings
Fig. 1 is the structural principle synoptic diagram of the utility model.
Fig. 2 is the said public address system circuit theory diagrams of the utility model.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in Figure 1; The utility model mainly comprises the recording module 1 that has storage card and the module 2 that amplifies; Described recording module 1 is by panel button control or acoustic control system, and said recording module 1 is provided with the microphone interface 3 that is connected with the microphone of recording.The above-mentioned recording system that mainly is made up of recording module mainly is responsible for the audio file recording, and it has keying and acoustic control function; Can start, suspend and stop recording by button; The acoustic control function then promptly by sound control, realizes that noiseless or sound stops sound recordings automatically when being low to moderate setting value, begins recording when recovering sound automatically, and this function has been saved storage space and the continuity that has guaranteed recording file.
The described module that amplifies mainly is made up of microphone, amplify chip and loudspeaker, and the microphone output signal one tunnel of the module that amplifies is connected to recording module, and another road exports the module that amplifies to; Also link to each other on the described recording module with the said module that amplifies.
The public address system that mainly is made up of the module that amplifies is mainly used in amplifying of voice in the processes such as operation steps, action, safety practice, the division of labor.
The described storage card of the utility model is mainly used in the preservation recording file.
Also be provided with the display interface that connects LCD display 4 on the said recording module 1.
Shown in Figure 2, said amplifying links to each other with an amplifying triode Q1 through a capacitance C8 before the chip TEA2025, said microphone output signal wherein one the tunnel be connected in described amplifying triode Q1.
Said recording module 1 links to each other with external power supply through a Battery pack group 5 and charging socket 6 with the module 2 that amplifies.
Embodiment:
Adopt recording module, the storage card of capacity 8G can be realized 50 hours high-quality MP3 recording mode (320kbps) recording.Also have the voice playing function, can play MP3 music and the language that records.Support the sound control recording function, automatic pause recording when external sound is too little.In addition, recording module supports flash card to expand, the MicroSD card of the highest support 16G M2 memory stick or 32G.In Recording Process, after currently used memory capacity is full, will automatically switches to store card and continue and record, to guarantee the continuity of recording.Support the sound control recording function simultaneously:, continue recording when sound is arranged automatically when too hour automatic pause recording of external sound.
The module that amplifies adopts TEA2025 power amplifier chip and sound equipment, and output power can reach 4.7W, and voice output is clear loud and clear.MIC signal one road is recorded to recording module, and one the tunnel at first advanced triode Q1 cascode amplifies.The quiescent current of triode Q1 is about 1mA, and the collector quiescent voltage is about 3V, and voice signal amplifies after C8 goes into power amplifier TEA2025 at a distance from direct sending through Q1 and carries out power amplification.
