Abstract

The invention belongs to the technical field of buzzers, and discloses a noise-reducing strong-sound electronic buzzer and its control system and control method. A sound-enhancing wall is welded and installed on the left and right sides of the resonance cavity, and the sound-enhancing wall is sleeved with a Elastic sleeve, elastic sleeve and dust cover, the dust cover is embedded with a dust net; the end of the elastic sleeve is sewn with a fixed soft card, and the fixed soft card is provided with a convex head, the elastic sleeve The right end is sutured and fixed with a fixing belt, and the fixing belt is sutured and fixed with a buckle, and the buckle is connected with the protruding head; at the place where the sound reinforcement wall and the resonance chamber are welded, a sound outlet is welded and installed, and there is a sound outlet around the outside of the sound outlet. There is a circle of noise-reduction grille at one circle, and the noise-reduction grille and the sound outlet are vertically staggered. The present invention further enhances the sound wave energy generated by the buzzer through the physical structure, weakens the energy of external noise, thereby improving the sound performance of the electronic buzzer, and reducing the influence of different external environmental factors on the electronic buzzer.

Description

technical field [0001] The invention belongs to the technical field of buzzers, and in particular relates to a noise-reducing strong-pitch electronic buzzer, a control system and a control method thereof. Background technique [0002] Electronic buzzers are generally composed of simple electronic circuits and piezoelectric speakers. The simple circuits are composed of a small number of electronic components, and the piezoelectric speakers are composed of piezoelectric ceramic sheets and sound-aiding chambers. There are two types of electronic buzzers: electronic buzzers and musical buzzers. [0003] At present, the existing electronic buzzer dustproof device cannot be adjusted according to the size of the sound reinforcement wall, which reduces the wide usability and increases the cost of replacement. At the same time, when the existing electronic buzzer buzzes, the sound is mixed with noise, which reduces the clarity of the buzzer. [0004] In summary, the problems in the...
