Description

Technical Field

[0001] This utility model relates to the field of horn technology, and in particular to a vehicle alarm horn device. Background Technology

[0002] A loudspeaker is an electroacoustic transducer that converts electrical signals into sound waves. It is widely used in audio systems, broadcasting, communications, automotive electronics, and other fields. Its core function is to drive a diaphragm to vibrate using principles such as electromagnetism, piezoelectricity, or electrostatics, thereby generating sound waves in the air and playing sound.

[0003] However, existing vehicle alarm horn devices still have certain defects: when in use, the horn often gets damp due to external moisture or rain, which causes the horn sound to become distorted. Also, when the horn is in the car, the shaking of the vehicle body may cause the horn fixing device to loosen, causing the horn to fall off.

[0004] A search revealed Chinese Patent Publication No. CN117750284B, which discloses a vehicle-mounted horn device with a shock-absorbing structure. The device includes a mounting base and a first horn unit, a fixed housing with an opening at its upper end, and a sliding housing that can slide along the height of the fixed housing. The fixed housing is fixedly connected to the mounting base. The sliding housing includes an outer peripheral wall and an inner peripheral wall, with a space between them. The inner peripheral wall is slidably inserted into the fixed housing. The mounting base is equipped with an electric component for driving the sliding housing to slide. The outer peripheral wall has a first horn mounting hole. The fixed housing is fixedly connected to the mounting base. A permanent magnet ring is disposed on the outer side of the inner peripheral wall, and an excitation coil is disposed on the side of the mounting base facing the permanent magnet ring. This invention provides a vehicle-mounted horn device with a shock-absorbing structure, offering good shock absorption and a superior user experience. However, the device has poor waterproofing performance, and prolonged use may cause horn sound distortion due to moisture absorption. Utility Model Content

[0012] According to the vehicle alarm horn device, the inner side of the housing is a cavity structure, and a sealing cover is fixedly connected to the inner side of the upper part of the housing. A sound transmission hole is opened on the upper part of the sealing cover.

[0013] According to the vehicle alarm horn device, a frame is fixedly connected to the bottom of the housing, and a sound cavity is fixedly connected to the top of the frame.

[0014] According to the vehicle alarm horn device, a waterproof layer is fixedly connected to the inner side of the housing.

[0015] The above-mentioned solution has the following beneficial effects:

[0016] By installing a waterproof layer on the outside of the speaker's sound cavity, the speaker's waterproof performance is significantly improved, preventing distortion caused by water ingress or moisture.

[0017] By installing a spring-loaded buckle device under the speaker connector, the connection between the connector and the connector frame is more stable and easier to disassemble. This not only improves the stability of the speaker assembly after connection but also enables quick disassembly of the connector and the connector frame.
