Description

Technical Field

[0001] The utility model relates to the technical field of automobile speakers, in particular to an automobile speaker shell. Background Art

[0002] The function of a car horn is to warn pedestrians and attract the attention of other vehicles. Car horns are basically equipped on every car. When the horn button on the steering wheel or other locations is pressed, the current from the battery will flow through the circuit to the electromagnetic coil of the horn relay. The electromagnetic coil attracts the moving contact switch of the relay to close, and the current will flow to the horn. The current makes the electromagnet inside the horn work, thereby causing the diaphragm to vibrate and make a sound.

[0003] The utility model patent application document with publication number "CN215818475U" discloses a car horn that can adjust the volume according to power. It is mainly composed of a device body and a detection and adjustment device. This technical solution can collect the volume according to the actual situation on site, and then transmit it to the volume controller through a wire. The volume controller then adjusts the volume that the horn needs to transmit according to the collected volume, thereby enhancing the practicality of the horn. At the same time, it prevents water from entering the horn during rainy days and causing water damage to the horn, and prevents debris from entering the horn and blocking the sound outlet, affecting the normal use of the horn, and extending the use time of the horn.

[0004] The car horn disclosed in the above document has the following defects: a dustproof net is provided inside the horn housing of the car horn to prevent internal dust, but the horn housing is easily affected by external factors during installation and use, causing damage to the dustproof net, thereby affecting the dustproof effect of the horn.

[0005] It can be seen from this that the existing speaker housing does not have a structure for protecting the dustproof net, and it is necessary to improve the existing shortcomings and provide a car speaker housing. Utility Model Content
