Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but does not limit protection range of the present utility model and range of application:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of audio amplifier, comprise sound box 1, in the resonator 12 of described sound box 1, air-tightness is provided with movably and resonator 12 is divided into the demarcation strip 4 of the first chamber 10, second chamber 11, one end of described first chamber 10 is provided with loudspeaker 2, and one end that described second chamber 11 is relative with loudspeaker 2 is provided with the row pressure mouth 13 of the pressure for discharging the second chamber 11.
In the resonator 12 of sound box 1, air-tightness is provided with moveable demarcation strip 4, second chamber 11 is provided with row pressure mouth 13, when the pressure in the first chamber 10 in external pressure or hydraulic pressure and sound box 1 not etc. time, sound box 1 promotes demarcation strip 4 by the inlet, outlet of row pressure mouth 13 or water-in and water-out and moves and regulate, until the pressure of sound box 1 external pressure, the first chamber 10 and the pressure of the second chamber 11 reach balance, thus prevent external pressure or variation in water pressure and cause loudspeaker 2 to damage.
The audio amplifier of the present embodiment, please refer to Fig. 1, Fig. 2, Fig. 3, and the basis of previous technique scheme can be specifically, and described row pressure mouth 13 is provided with outward extending discharge pressure pipe 8, and described discharge pressure pipe 8 is provided with two-way automatic regulating valve 6.When sound box 1 external pressure or variation in water pressure, demarcation strip 4 moves, and two-way automatic regulating valve 6 is automatic conducting discharge pressure pipe 8 after bearing certain pressure, plays the effect of buffering row pressure.Described discharge pressure pipe 8 is also provided with manual modulation valve 7.When sound box 1 external pressure and the pressure of the first chamber 10, the pressure of the second chamber 11 keep balance, turn off manual modulation valve 7, can avoid causing demarcation strip 4 to move because of the conducting of two-way automatic regulating valve 6 in loudspeaker 2 audio plays process, cacophonia; Fixed cavity can also be provided for audio plays, avoid the distortion of audio frequency.
The audio amplifier of the present embodiment, please refer to Fig. 1, Fig. 2, Fig. 3, and the basis of previous technique scheme can be specifically, and described row pressure mouth 13 is provided with outward extending discharge pressure pipe 8, and described discharge pressure pipe 8 is provided with manual modulation valve 7.Discharge pressure pipe 8 is provided with manual modulation valve 7, when sound box 1 external pressure and the pressure of the first chamber 10, the pressure of the second chamber 11 keep balance, turns off manual modulation valve 7, demarcation strip 4 in loudspeaker 2 audio plays process can be avoided to move, cacophonia; Fixed cavity can also be provided for audio plays, avoid the distortion of audio frequency.
