Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted speakers, in particular to a waterproof, dustproof and iron-chip-proof structure of a vehicle-mounted speaker. Background Art

[0002] Speakers, commonly known as horns, are more important in car audio systems. To make car speakers show excellent timbre and positioning, the technical requirements and difficulty are much higher than those of home audio. The disadvantages of car speakers are numerous and complex, because there are some disadvantages in the interior space of the car that are not found in the house: narrow space, irregular objects, complex environment (noise, vibration, car materials, etc.) and the installation position of the speaker (limited by the interior and exterior shape of the car); more importantly, the listening position is not good, biased to the left and right; and because the direction of the speaker is not evenly symmetrical from the front, it leads to complex frequencies, phase differences and peaks, troughs, standing waves, reflective time differences, long reverberation time (resonance), etc., which are not conducive to listening. Traditional speakers are made of nylon mesh or non-woven materials, which are not durable and easily contaminated. Therefore, a waterproof, dustproof and iron filings-proof structure for a car speaker is proposed to solve the problems mentioned in the above background. Utility Model Content
