Description

[Technical Field]

[0001] The utility model relates to the technical field of audio devices, in particular to an audio device for multimedia integrated dual-recording cameras of passenger cars with reasonable structural design and high usage experience. [Background Art]

[0002] Audio devices are relatively common equipment in people's daily lives, especially audio devices applied to passenger cars. With the continuous development and progress of technology, the usage performance and experience of audio devices have been greatly improved. In general designs, audio devices are fixedly installed at the corner parts or roof parts inside passenger cars, with relatively fixed structural designs. In such cases, there is a problem that the angle cannot be adjusted well according to the actual application scenario requirements in actual applications. For example, there are more passengers on one side and no sound is needed on one side, etc. The prior art generally uses soft adjustment, but the usage experience still cannot be achieved well in actual use.

[0003] For example, the utility model patent with the application number CN201620236924.6 and the patent name "An automotive audio for adjusting the sound transmission direction" specifically discloses an automotive audio for adjusting the sound transmission direction, including: a speaker, a power amplifier circuit, a reduction motor, an arc-shaped rack and an adjustment switch. The rear end of the speaker is connected to the arc-shaped rack, the arc-shaped rack meshes with the reduction motor, and the adjustment switch is electrically connected to the motor. When the adjustment switch is pressed, the speaker opening rotates up and down to adjust a certain angle. Since the utility model is provided with a reduction motor, an arc-shaped rack and an adjustment switch, the rear of the speaker is connected to the arc-shaped rack, the arc-shaped rack meshes with the reduction motor, and the adjustment switch is electrically connected to the motor. When the adjustment switch is pressed, the speaker opening rotates up and down to adjust a certain angle, so that the speaker direction is adjusted to the best direction felt by the listener, significantly improving the sound effect of the audio, with simple structure and convenient production and manufacturing.

[0004] Although the technical solutions of the above-mentioned prior designs have improved the angle adjustment performance of audio devices to a certain extent, there are still problems of being less user-friendly, less convenient, and having a complicated structure in actual use.

[0005] Based on this, it is necessary to improve and optimize from the specific structural parts of the prior designs. [Content of the Utility Model]
