Buzzer structure convenient for installation and having combo audio

Abstract

The invention discloses a buzzer structure convenient for installation and having a combo audio. The buzzer structure comprises a housing, a buzzer and a resonant chamber. A piezoelectric buzzer is installed in the housing. The resonant chamber is arranged at the top end of the piezoelectric buzzer. An outer ring is installed at the bottom of the housing. The invention is scientific and reasonablein structure, and safe and convenient in use; and an outer ring is arranged for the invention. Through the effects of a sliding slot, a groove, a sliding block and a fixing block, the sliding block slides and the position of the fixing block is adjusted according to an actual situation of the installing position. By matching the effects of a connecting screw rod and a locking nut, the position thereof is fixed, such that the buzzer is better installed and fixed. Through the effect of a movable shaft, the fixing block is folded and hidden conveniently according to an actual requirement, thereby achieving a simple operation and a convenient installation. Through the effects of a through hole, an inner ring and a bearing hole as well as an extrusion bump, the bearing hole at one side of theinner ring is made overlapped with the through hole, thereby circulating air at the bottom of the buzzer and improving heat dissipation effects of the buzzer.

Description

technical field [0001] The invention relates to the field of buzzer technology, in particular to a buzzer structure with composite audio for easy installation. Background technique [0002] The buzzer is an electronic sounder with an integrated structure. It is powered by DC voltage and is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, and timers. , where the composite audio buzzer includes a piezoelectric buzzer, and the piezoelectric buzzer is mainly composed of a multivibrator, a buzzer, an impedance matcher, a resonance box, and a shell, etc., and is generated by the sound of the buzzer Composite audio, the existing buzzer has a simple structure, and the shell is fixed as a whole. When the mounting hole of the fixed plane does not fit with the fixing block of the buzzer due to errors, it makes the installation of the buzzer difficult, and the connection is...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a conveniently installed buzzer structure with composite audio, which can effectively solve the problem that the existing buzzer proposed in the background art has a simple structure, and the outer shell is fixed in one piece. It does not fit the fixed block of the buzzer, which makes it difficult to install the buzzer, and the excessively long connecting wire is exposed, which will also cause it to be entangled with external objects, affecting the normal operation of the device, and the problem of time-consuming and laborious installation
