Description

Technical Field

[0001] The utility model relates to the technical field of automobile loudspeakers, in particular to a high-strength automobile loudspeaker mask. Background Art

[0002] Car speakers are devices installed inside a car to play audio signals. They are usually driven by the car audio system to provide music, navigation prompts, radio broadcasts and other sound outputs to the passengers in the car.

[0003] The following are the specific functions:

[0004] Music playback: Car speakers are responsible for playing music from various audio sources (such as CD, MP3, Bluetooth devices, etc.), creating a pleasant riding environment for drivers and passengers;

[0005] Voice communication: In the car phone system or car navigation system, the speaker is used to play the incoming call ringtone, call sound and navigation instructions to ensure that the driver can clearly receive this information;

[0006] Warning and prompt sounds: In some car systems, such as reversing radar, automatic braking system, etc., the speaker will emit warning sounds or prompt sounds to alert the driver;

[0007] Audio and video entertainment: For car audio systems equipped with video playback function, the speakers also play the sound of movies and videos to provide entertainment for rear passengers;

[0008] Vehicle Noise Suppression: Some advanced car audio systems utilize speakers to play out-of-phase waveforms to cancel out noise inside the vehicle and improve overall listening comfort.

[0009] Types of car speakers include full-range speakers, subwoofers, mid-range speakers, tweeters, etc. They may be distributed in different parts of the car, such as door panels, dashboards, trunks, etc., to achieve the best sound field effect.

[0010] Additionally, high-end automotive audio systems may integrate more complex speaker designs, such as surround sound systems and customized audio components to provide a cinematic listening experience.

[0011] At present, when loudspeakers are used in cars, especially in some long-distance tourist buses, in order to ensure air circulation in the car, the windows will be opened for a long time for ventilation when driving or stopping for repairs in suitable weather. However, due to the large amount of hair and dust outside, if the loudspeakers are exposed to the external environment for a long time, it is easy to adhere to a large amount of hair and dust, causing the sound quality of the loudspeakers to be distorted and the efficiency of the sound to be reduced, greatly reducing the safety of using horn warnings during driving.
