Embodiment 1

[0063] When the car audio is installed in the SUV / MPV model, according to the installation position of the car audio, calculate the angle at which the front of the audio is broadcast and refracted by the rear cover glass. In the SUV model, the installation angle of the car audio is 30-60° ,like figure 1 As shown, for a fixed SUV model, most of the SUV rear cover glass has an inclination angle of 45°, and the front side of the car audio can be set to 45°, and the reflected sound of the car audio is at 0°. Diffusion to the cabin space.

Embodiment 2

[0065] When the car audio is installed in a sedan model, according to the installation position of the car audio, calculate the angle at which the sound is transmitted from the front and refracted by the rear cover glass. In the car model, the installation angle of the car audio is 30-60° , for car models, such as figure 2 As shown, most of the car rear cover glass is placed above the front of the audio system. The front side of the car audio can be set to be horizontal, and the reflected sound of the car audio diffuses to the cabin space at an angle of 0°.

Abstract

An integrated digital vehicle sound equipment system is disclosed. Vehicle sound equipment is arranged behind a headrest assembly of a rear-row seat, and the front side of the sound equipment is at a 0-90-degree included angle to the horizontal plane. The vehicle sound equipment is provided with a bar-shaped housing with a semi-elliptic cross section. The housing is divided into a left sound box and a right sound box, which are symmetric, through a baffle plate, and a digital audio control system is arranged in the housing. The integrated digital vehicle sound equipment system has the advantages of small size, small occupied area, lossless installation, dismounting convenience, easy operation, flexible application and high fidelity sound quality.

Description

technical field [0001] The invention relates to an audio system, in particular to an integrated digital vehicle audio system. Background technique [0002] The interior of the car compartment is a special sound field environment. Not only is the interior space of the compartment limited and the listening area is small, but there are also two different acoustic characteristics in the same space: A strong reflection sound field space is formed, and a large amount of sound waves are absorbed by the soft materials such as seats, carpets, and patches in the lower part of the compartment, because the seats not only block the propagation of sound waves, but also change the sound waves due to their irregular geometric surfaces. Diffusion is formed in the direction of the sound, thus forming a complex sound field space that absorbs and reflects diffusion. [0003] At present, most car audio speakers are installed in the lower part of the car door. Due to the structure and cost const...
