Abstract
Adopt monolithic processor controlled self-adaptation disc type horn.In different operating environments, the frequency of loudspeaker physical construction itself will change, and the oscillation frequency of loudspeaker does not change in conventional horn work, and frequency has therebetween resonated with regard to not existing, and then causes the cacophonia of loudspeaker.The utility model composition comprises: circuit board (1), it is characterized in that: described circuit board (1) is connected with electromagnetic mechanism (2), described electromagnetic mechanism (2) is connected with counterweight (3), described counterweight (3) is connected with diaphragm (4), described diaphragm (4) is connected with the sheet that amplifies (5), and described diaphragm (4) is connected with described circuit board (1).The utility model is for applying the control of speaker sound effect.
Description
technical field:
the utility model relates to the monolithic processor controlled self-adaptation disc type horn of a kind of employing.
background technology:
determine band electronic disc type horn when dispatching from the factory, the sense of hearing mainly through professional is adjusted to the vibration frequency of loudspeaker consistent with the frequency of the physical construction of loudspeaker itself, makes the frequency of the two almost close to resonance, to such an extent as to reaches best sound effect; But after dispatching from the factory, in different operating environments, the frequency of loudspeaker physical construction itself will change, and the oscillation frequency of loudspeaker does not change in loudspeaker work, frequency has therebetween resonated with regard to not existing, and then causes the cacophonia of loudspeaker.
utility model content:
the purpose of this utility model is to provide the monolithic processor controlled self-adaptation disc type horn of a kind of employing.
above-mentioned object is realized by following technical scheme:
the monolithic processor controlled self-adaptation disc type horn of a kind of employing, its composition comprises: circuit board, described circuit board is connected with electromagnetic mechanism, described electromagnetic mechanism is connected with counterweight, described counterweight is connected with diaphragm, described diaphragm is connected with the sheet that amplifies, and described diaphragm is connected with described circuit board.
described monolithic processor controlled self-adaptation disc type horn, described circuit board comprises sound transducer and single-chip microcomputer, and described sound transducer and described single-chip microcomputer are welded on described circuit board.
beneficial effect:
1. the utility model adds single-chip microcomputer and sound transducer, makes loudspeaker have adaptive ability.
a close-loop feedback is formed during utility model works, ensure the vibration frequency of diaphragm with the driving frequency of loudspeaker close to consistent, reach resonance, can work under different operating environment (comprising: hyperbaric environment, environment under low pressure, hot environment and low temperature environment etc.), guarantee tone quality of horn is best, solves the problem of determining band electronic disc type horn and can not adapt to working environment change.
the utility model circuit structure is succinct, and installation steps are few, improve efficiency of assembling.
the driving of loudspeaker is done in the pulse of the utility model single-chip microcomputer output certain frequency, control the break-make of electromagnetic mechanism, and then the to-and-fro movement of adhesive weight belt dynamic diaphragm, diaphragm vibration frequency is gathered by sound transducer, and this frequency is delivered to single-chip microcomputer, single-chip microcomputer by algorithm using the vibration frequency of diaphragm as driving, go again to control electromagnetic mechanism, so go down, form a close-loop feedback, the guarantee vibration frequency of diaphragm close to consistent, reaches resonance with the driving frequency of loudspeaker, ensures the sound effect that loudspeaker reach best.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is vertical views of accompanying drawing 1.
embodiment:
embodiment 1:
the monolithic processor controlled self-adaptation disc type horn of a kind of employing, its composition comprises: circuit board 1, described circuit board 1 is connected with electromagnetic mechanism 2, described electromagnetic mechanism 2 is connected with counterweight 3, described counterweight 3 is connected with diaphragm 4, described diaphragm 4 is connected with the sheet 5 that amplifies, and described diaphragm 4 is connected with described circuit board 1.
embodiment 2:
monolithic processor controlled self-adaptation disc type horn according to embodiment 1, described circuit board 1 comprises sound transducer 6 and single-chip microcomputer 7, and described sound transducer 6 and described single-chip microcomputer 7 are welded on described circuit board.
