Abstract

The invention discloses a buzzer, a buzzing device comprising the buzzer and security equipment comprising the buzzer or the buzzing device. The buzzer comprises a housing and a buzzing sheet which ismatched with the housing to form a cavity; and the cavity is provided with a sound production hole communicated with the outside, and the cavity is constructed in a manner that the ratio of the outerdiameter of the cavity to the height of the buzzer is greater than 6.5, and / or the ratio of the diameter of the sound production hole to the inner diameter of the cavity is not greater than 0.5. Thebuzzer has the advantages of being low in manufacturing cost, compact in structure, stable in working performance and the like; the loudness of the buzzer can be remarkably improved; and the requirements for sound pressure levels of different frequency bands can be met.

Description

technical field [0001] The present invention relates to the technical field of sounding devices, in particular to a buzzer, a buzzer including the buzzer, and security equipment including the buzzer or the buzzer. Background technique [0002] Various types of buzzers have been widely used in many fields such as security, and especially constitute an important part of many signaling devices. When the set conditions are triggered, this kind of buzzer can be used to provide an alarm function so as to form a reliable safety mechanism.
