Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as figure 1 and figure 2 As shown, the present invention includes a base 1, an electromagnetic drive device 2 and an upper cover 3. The top of the base 1 is provided with an electromagnetic drive device 2 and an upper cover 3. The upper cover 3 is covered on the outside of the electromagnetic drive device 2. The upper cover 3 adopts heat dissipation performance Good adhesive bond to base 1. The base 1 is a hollow cylindrical structure, and the bottom of the inner chamber of the base 1 is equipped with a rotating drive device. The rotary driving device includes a rotary motor 13, which is installed at the central position of the inner bottom of the base 1, and the center of the rotary motor 13 is covered with a rotating shaft 12, and the top of the rotating shaft 12 is fixed to the top of the inner cavity of the base 1. The rod 14 and the rotating motor 13 ca...

Abstract

The invention discloses a sustainable sound production electromagnetic buzzer with a heat dissipating function. The sustainable sound production electromagnetic buzzer comprises a base, an electromagnetic driving device and an upper cover; the electromagnetic driving device and the upper cover are arranged on the base, and the outer side of the electromagnetic driving device is covered with the upper cover; a rotation driving device is mounted in an inner cavity of the base, and a cross rod is mounted above the rotation driving device; a pair of conductive joints is arranged on one side of thecross rod, and a plurality of pairs of conductive contacts are arranged at the top of the inner cavity of the base; and the conductive contacts can make contact with the conductive joints; the top ofeach pair of conductive contacts is connected with a set of electromagnetic driving devices. By arranging the three electromagnetic driving devices, at the same time, only one electromagnetic drivingdevice is powered on to drive vibrating reeds to vibrate to produce sound, the working time of each single coil is effectively shortened, and in the case of long-time buzzing of the buzzer, each coilstops working for a period of time to avoid burnout caused by continuous heating to the buzzer.

Description

technical field [0001] The invention relates to the technical field of electromagnetic buzzer equipment, in particular to a sustainable sounding electromagnetic buzzer with heat dissipation function. Background technique [0002] The electromagnetic buzzer is an electroacoustic device that passes an audio signal through an electromagnetic coil to generate a changing magnetic field to push a metal diaphragm to vibrate and sound. The existing patent is an electromagnetic buzzer with heat dissipation function (Patent No.: 201711361381.6). The bottom of the buzzer body is connected to the colored lens through a snap connector, and a heat dissipation layer is arranged under the colored lens. A plugboard is fixed on one side of the protective case, and a power adapter is installed on the plugboard, and a heat dissipation groove is opened on the surface of the power adapter, and the electronic components inside the buzzer body are arranged on the side of the buzzer body through a h...
