Problems solved by technology

[0005] We found that the Hall electronic horns, non-contact electronic horns and mechanical contact horns currently in use with adaptive control methods have the same problem: the mechanical action of the moving stem and the vibrating diaphragm cannot reach a reasonable resonance state , the diaphragm vibrates and sounds under the action of the applied current. When the diaphragm moves to the lower turning point, the position sensor acts and controls the switch tube to be powered off so that the diaphragm releases and rebounds; it is hoped that the diaphragm will release and rebound to the corresponding position above and the

Abstract

The invention relates to an electronic loudspeaker and discloses an induction type self-adapting electronic loudspeaker. The structure of the induction type self-adapting electronic loudspeaker comprises a loudspeaker shell, wherein a frequency acquisition sensor is arranged at the internal bottom of the loudspeaker shell; a moveable stem is arranged above the frequency acquisition sensor; the moveable stem is connected with a loudspeaker sound board; a sounding part is arranged above the loudspeaker sound board; and the frequency acquisition sensor is connected with an electronic main board through a working inductance driving circuit. Compared with the prior art, the induction type self-adapting electronic loudspeaker of the invention has the characteristics of rational design, simple structure, convenient installation, precise detection, high working efficiency, convenient modulation and suitability for mass production.

Description

technical field [0001] The invention relates to an electronic horn, in particular to an inductive self-adaptive electronic horn. Background technique [0002] At present, car electric horns are divided into two categories according to the control method. One is the input mode outside the frequency, which is controlled by various electronic circuits outputting a certain fixed frequency and duty cycle. The products are all non-contact electronic horns; the other is self-adaptive. The method is that the position sensor controls the amplitude, and the vibration frequency is determined by the speaker itself. Its products mainly include traditional mechanical contact speakers and Hall-type non-contact electronic speakers. [0003] In the car electric horn that adopts the input mode outside the frequency, the computer chip drives the horn to have the disadvantage that the control frequency is fixed. This kind of horn takes a long time to debug. The actual vibration frequency of th...
