Independent sound system for car seat

Abstract

The invention discloses an independent sound system for a car seat. The system comprises a headrest, sound boxes, a power amplifier and sound sources, wherein the power amplifier is in signal connection with both the sound boxes and the sound sources; the headrest comprises a middle headrest part, and wing parts which are located on the left and the right sides of the headrest part and extended forward; a cavity, in which the corresponding sound box can be embedded, is formed in each wing part; each wing part can horizontally swing from side to side through a vertical rotating shaft; and the intersection angle between the central axis of a loudspeaker in each sound box and the central axis of the headrest ranges from 80 DEG to 100 DEG. The independent sound system for the car seat providedby the invention has the advantages that the sound boxes are arranged at a left wing part and a right wing part of the headrest close to the head of a driver / passenger, so that a left loudspeaker anda right loudspeaker can respectively face and be close to the left ear and the right ear of the driver / passenger within a small range and a short distance, and stereo sound field effects of near-field listening through ''open earphones'' can be further generated; and meanwhile, mutual effects between the current system and independent sound boxes in other seats of a same car can be avoided, a sense of pressure caused by earphones can be prevented, and the ''in-head effect'' of the earphones can be further eliminated.

Description

technical field [0001] The invention relates to the technical field of car audio equipment, in particular to an independent car seat audio system. Background technique [0002] Existing family cars are generally equipped with a sound power amplifier system, which cooperates with other functional modules in the car to realize the functions of listening to radio programs, playing music, and even answering mobile phones. If the driver wears headphones while driving, it is more dangerous and will affect his judgment on the surrounding environment of the car. Therefore, the audio system of most cars mainly includes the car audio of the original car. [0003] The earphone is a kind of near-field listening equipment, that is, the earphone diaphragm is close to the ear to listen to music, which makes the attenuation of the sound wave transmission in the air medium almost zero, so its attenuation and distortion in the air medium are very small. So this way of listening to audio is t...

Problems solved by technology

In terms of fidelity alone, it is easier for earphones to obtain weak details such as full-range and transient music playback, but it is difficult for long-distance speakers to achieve this, because it requires high equipment costs to obtain restore the lost part
