Abstract
The utility model discloses a power supply system of an integrated audio frequency amplification circuit. The power supply system comprises a power supply module and an audio frequency amplification module in connection with a mainboard. One output end of the power supply module is connected with the power input end of the audio frequency amplification module, and the power supply module and the audio frequency amplification module are integrated on a same circuit board. By adopting the power supply system provided by the utility model, the connecting wires between the power supply module and the audio frequency module is reduced, the occupied space of the circuit board is reduced, and the electrical performance is improved; moreover, the power supply system has short signal path and high anti-electromagnetic interference capacity.
Description
Technical field
The utility model relates to electric supply system, especially relates to the electric supply system of integrated audio amplifying return circuit.
Background technology
At present the audio frequency amplification module of the power supply module of electric supply system and audio amplifier system is two modules independently, be located at respectively on the different circuit boards, the output of power supply module is connected by the power input of connecting line with the audio frequency amplification module, for this audio amplifier system provides power supply.Because the connecting line of two modules comes off easily, causes between two systems and exists potential safety hazard.
The utility model content
In order to overcome above-mentioned shortcoming, main purpose of the present utility model is to provide the electric supply system that need not the integrated audio amplifying return circuit that connecting line is connected between a kind of power supply module and audio frequency amplification module.
The utility model comprises power supply module and the audio frequency amplification module that links to each other with mainboard, one output of described power supply module links to each other with the power input of described audio frequency amplification module, and described power supply module and described audio frequency amplification module are integrated on the same circuit board.Therefore, need not connecting line between the utility model power supply module and audio frequency amplification module and be connected, can prevent the problem that connecting line comes off.
The utility model compared with prior art has following advantage: 1, reduced the be connected wire rod of power supply module with audio-frequency module, can prevent problem that connecting line comes off and safer; 2, reduce the volume that circuit board takies, improved electric property; 3, signal path is shorter, and anti-electromagnetic interference capability is strong.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: Fig. 1 is a structural representation of the present utility model; Fig. 2 is the circuit diagram of power supply module of the present utility model; Fig. 3 is the circuit diagram of audio frequency amplification module of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises power supply module 2 and the audio frequency amplification module 3 that links to each other with mainboard 1, one output of described power supply module 2 links to each other with the power input of described audio frequency amplification module 3, and described power supply module 2 and described audio frequency amplification module 3 are integrated on the same circuit board 4.Power supply module 2 of the present utility model is respectively mainboard 1 and 3 power supplies of audio frequency amplification module, the work of mainboard 1 control power supply module 2 and audio frequency amplification module 3.Shown in Fig. 2,3, one output 5 of power supply module 2 links to each other with the input 6 of audio frequency amplification module 3, power supply module 2 provides power supply for audio frequency amplification module 3, and described power supply module 2 is integrated on the same circuit board 4 with described audio frequency amplification module 3; All the other outputs of power supply module 2 provide power supply for other circuit.
