Description

Technical Field

[0001] The utility model belongs to the technical field of flash buzzers, and in particular relates to a durable flash buzzer. Background Art

[0002] The flash buzzer is a buzzer device used in the vehicle turn signal circuit. It is used to control the flash and emit a warning sound to reduce hidden dangers. The flash buzzer is now widely used in land transportation vehicles such as cars, motorcycles, and electric vehicles.

[0003] The flash buzzers on the market today have structural problems. The buzzer head is simply fixed in its exclusive round groove. The buzzer head is affected by its own vibration and the vibration of the vehicle. Later, it is easy to fall off from the round groove into the circuit cavity. This will first affect the sound effect. Secondly, the circuit is easy to break after the buzzer head falls off, affecting the service life of the buzzer. Utility Model Content

[0004] In order to overcome the above technical problems, the utility model provides a durable flash buzzer whose buzzer head is not easy to fall off.

[0005] The utility model adopts the following technical solutions:

[0006] A durable flash buzzer comprises a shell, wherein the shell is divided into a resonance cavity and a circuit cavity, wherein the resonance cavity and the circuit cavity are separated by a partition, wherein the partition has a circular groove, wherein a buzzer head is installed in the circular groove, and a cover plate is installed at the mouth of the circuit cavity, wherein the top of the buzzer head is not lower than the notch of the circular groove, and the lower surface of the cover plate is fixedly connected to a circuit board, wherein the circuit board is vertical, and the bottom end of the circuit board abuts against the buzzer head.

[0007] Preferably, a pair of asymmetrical slots are formed on a group of opposite sides of the cover plate, and a corresponding locking protrusion is formed on the inner side of the edge of the shell.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] In the utility model, the rigidity of the circuit board is reasonably utilized to make it abut against the buzzer head, so that the buzzer head is difficult to fall off from the circular groove and has a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Unless otherwise specified, the raw materials and equipment used can be purchased from the market or are commonly used in the art. The methods in the embodiments are conventional methods in the art unless otherwise specified. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0015] A durable flash buzzer comprises a shell 1, which is divided into a resonance chamber 2 and a circuit chamber 5. The resonance chamber 2 and the circuit chamber 5 are separated by a partition 6. The partition 6 has a circular groove 7. A buzzer head 8 is installed in the circular groove 7. A cover plate 10 is installed at the edge of the circuit chamber 5. The top of the buzzer head 8 is not lower than the notch of the circular groove 7. The lower surface of the cover plate 10 is fixedly connected to a circuit board 9. The circuit board 9 is vertical, and the bottom end of the circuit board 9 abuts against the buzzer head 8. A pair of asymmetric card slots 4 are opened on a group of opposite sides of the cover plate 10, and a corresponding card protrusion 3 is provided on the inner side of the edge of the shell 1.

[0016] A durable flash buzzer, when used:

[0017] The working principle is the same as that of the existing flash buzzer. Relying on the abutment support of the circuit board 9, the buzzer head 8 in the circular groove 7 is difficult to fall off from the circular groove 7. The flash buzzer has high vibration resistance and long service life.

[0018] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the above embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
