Abstract
The utility model relates to a novel loudspeaker, belonging to the class of domestic appliances. The novel loudspeaker is formed by adding a set of identical voice coils on the basis of an original moving-coil loudspeaker, so that a loudspeaker can be used normally under the original conditions and has two resistant functions. After the individual, symmetrical and direct coupled amplification carried by an amplifier designed and provided with the loudspeaker, the positive and the negative half-corrugated currents of the inputted alternate current signals work via the synthesis of the self of the loudspeaker. Therefore, the amplifier has the advantages of good performance, wiring and easy adjustment. Moreover, when the loudspeaker is applied on a push-pull amplifier with an output transformer, the output transformer can be saved. Therefore, the loudspeaker can be a novel loudspeaker with higher practicability.
Description
This New-type loudspeaker belongs to the household electrical appliance class
The loud speaker of producing is one group of voice coil loudspeaker voice coil now, and when having only sound amplifier to export complete AC signal, therefore the ability operate as normal, makes the line of sound amplifier complicated.
Purpose of the present invention just provides a kind of device of New-type loudspeaker, with its structure of simplifying the sound amplifier line unit, improves the performance of sound amplifier, makes sound amplifier reach the effect of real amplification high-fidelity.
The utility model loudspeaker is to adopt form that one group of voice coil loudspeaker voice coil of coil-moving speaker more becomes two groups of voice coil loudspeaker voice coils namely: two groups of voice coil loudspeaker voice coils and around (head of one group of voice coil loudspeaker voice coil is an output with another tail joint of organizing voice coil loudspeaker voice coil, and another monic tail is other two outputs.) totally three outputs realize.
This New-type loudspeaker is owing to adopt many group voice coil loudspeaker voice coils.So the sound amplifier line unit is greatly improved.After taking highly symmetrical same transistorlike to amplify separately to the electric current of positive and negative half waveform of the AC signal of input during work, the thus synthetic and work of loudspeaker self.Therefore, the sound amplifier with this speaker unit has: circuit is simple, adjusts easily the efficient height, power utilization rate height, power output is big, can be suitable for operation at low power supply voltage, and homophase disturbs basic neutralisation, the hum noise is minimum, and frequency response is wide, and distortion is little, the advantages such as integrated circuit of being more convenient for.This New-type loudspeaker, as when installing and using on having the push-pull amplifier of output transformer, just can save output transformer, directly be connected on the amplifier and use.(also can equally use with ventional loudspeakers, become the loudspeaker with two kinds of impedance function.）
Figure (1) is wiring diagram and the symbol of this New-type loudspeaker voice coil loudspeaker voice coil.
Figure (2) is for using the simple sound amplifier line map of this New-type loudspeaker device.
Among the figure (2), Y is this New-type loudspeaker, and S is that employing is identical with this New-type loudspeaker voice coil loudspeaker voice coil form, has the microphone of novel moving-coil type three outputs of paraphase function.Operation principle is equal to class B amplifier.During adjustment, must make the not quiescent point of two power tubes of the mutual symmetry of level, just enter the amplification region and (promptly just walked out cut-off region.）
Figure (3) is for using the high-quality high-fidelity power amplification line map of this New-type loudspeaker device.
Among the figure (3), BG1, BG2 form emitter commissure phase inverter.Other sound amplifier with figure (2) device is identical.
The easily row that is easy to implement of this New-type loudspeaker just on the basis of former coil-moving speaker, increases by one group of identical voice coil loudspeaker voice coil, namely many outputs.
Claims (1)
1, a kind of New-type loudspeaker has two groups of voice coil loudspeaker voice coils, it is characterized in that two groups of voice coil loudspeaker voice coils and knot, and the tail end joint of the head end of one group of voice coil loudspeaker voice coil and another group voice coil loudspeaker voice coil is an output, and another monic tail is other two outputs.
