Abstract
The loudspeaker of width than change can be adapted to.Noise can be there is and change voice in existing frequency self-adaption loudspeaker.The utility model composition comprises: solenoid (1), described solenoid (1) is connected with driving circuit (2), described solenoid (1) is connected with mechanical sound-producing device (6), described driving circuit (2) is connected with oscillatory circuit (3), described oscillatory circuit (3) is connected than Circuit tuning (4) with oscillating impulse width, described oscillating impulse width is connected with sensor (5) than Circuit tuning (4), and described sensor (5) is connected with described mechanical sound-producing device (6).The utility model is used for the control of speaker sound.
Description
technical field:
the utility model relates to a kind of width that adapts to than the loudspeaker changed.
background technology:
existing frequency self-adaption loudspeaker are due to ambient pressure and environment temperature, or during change in voltage, frequency self-adaption loudspeaker loudspeaker can occur noise or change voice.
utility model content:
the purpose of this utility model is to provide a kind of width that adapts to than the loudspeaker changed.
above-mentioned object is realized by following technical scheme:
a kind of width that adapts to is than the loudspeaker changed, its composition comprises: solenoid, described solenoid is connected with driving circuit, described solenoid is connected with mechanical sound-producing device, described driving circuit is connected with oscillatory circuit, described oscillatory circuit is connected than Circuit tuning with oscillating impulse width, and described oscillating impulse width is connected with sensor than Circuit tuning, and described sensor is connected with described mechanical sound-producing device.
beneficial effect:
1. the utility model drives the electronic circuit width of sound horn to change than the change with environment, the change that can conform is worked as due to ambient pressure and environment temperature, or change in voltage and when causing loudspeaker occur noise or change voice, sound frequency changes by sensor feedback to oscillatory circuit, make oscillation width than change, thus make it without noise and change voice, improve loudspeaker reliability and serviceable life.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
embodiment:
embodiment 1:
a kind of width that adapts to is than the loudspeaker changed, its composition comprises: solenoid 1, described solenoid 1 is connected with driving circuit 2, described solenoid 1 is connected with mechanical sound-producing device 6, described driving circuit 2 is connected with oscillatory circuit 3, described oscillatory circuit 3 is connected than Circuit tuning 4 with oscillating impulse width, and described oscillating impulse width is connected with sensor 5 than Circuit tuning 4, and described sensor 5 is connected with described mechanical sound-producing device 6.
Claims (1)
