The specific embodiment
As shown in Figure 1, the utility model is by an amplifier circuit for sound frequency signal D, and promptly the input of power amplification circuit connects audio signal source Mi, and output connects loudspeaker K.Other has the input of multistage amplifier circuit W to be connected on the output of amplifier circuit for sound frequency signal, and promptly the signal source of multistage amplifier circuit is picked up from loudspeaker.Motor M then is connected on the output of multistage amplifier circuit, and making its input power is the power output of multistage amplifier circuit, is based on the power of audio signal.Dc source U is supply audio frequency amplifying circuit and multistage amplifier circuit work then.
One specific embodiment, as shown in Figure 2, used audio amplifier circuit D is the TDA2822M power amplification circuit, its
Number pin connects audio signal source Mi,
Number pin and
Number pin each through a resistance with
Number pin,
Each connects number pin behind an electric capacity,
Number pin ground connection.
Number pin connects dc source U,
Number pin ground connection.
Number pin and
Number pin connects loudspeaker K, a loudspeaker electric capacity in parallel.
Number pin connects the base stage of a NPN type triode T1 through a capacitor C, this transistor base also connects dc source through a resistance, the grounded emitter of this triode, colelctor electrode connect the base stage of second NPN type triode T2, and the base stage of this triode also connects dc source, colelctor electrode through resistance connection dc source, grounded emitter through a resistance.The 3rd triode T3 arranged, and is the positive-negative-positive triode, and its base stage is connected through the colelctor electrode of a resistance with second triode, and its emitter stage connects dc source.The 4th triode T4 arranged, and is NPN type triode, and the base stage of the 4th triode is connected with the colelctor electrode of the 3rd triode, grounded emitter.Motor M is connected between the colelctor electrode of dc source and the 4th triode, and electric capacity and motor parallel are arranged.Be to save cost, the 4th triode, i.e. the used triode of output stage in the power amplification circuit, the in parallel use of also available a plurality of low-power transistors substitutes large power triode.
