Abstract

The invention relates to the technical field of buzzers, and especially relates to a welding-free high-frequency high-sound-pressure buzzer and a production method. The outer side face of an upper shell is provided with a step part. The outer side face of the step part is provided with at least two upper inserts. The outer side face of a lower shell is provided with lower inserts which can be connected with the upper inserts by means of insertion. The upper and lower inserts are internally provided with upper and lower insertion holes which are communicated, and the upper and lower insertion holes are internally provided with plugs which can move in the upper and lower insertion holes. The lower side of each lower insert is provided with a plurality of slots, and elastic jaws are formed on the side face of each lower insert between the slots. The upper shell and the lower shell are connected by a plurality of buckle devices. Two surface mounting components are arranged oppositely on a circuit board, and each surface mounting component includes a pin and a welding part. A coil is provided with avoiding parts in positions corresponding to the surface mounting components. The performance of the welding-free high-frequency high-sound-pressure buzzer is improved, and the installation mode is simplified. Moreover, the production process is optimized, the production efficiency is improved, and the cost is saved.
