AI Technical Summary

Problems solved by technology

The overall factors cause the internal temperature of the host to rise, which makes the electronic components aging
In order to solve this problem, the following solutions are generally adopted: 1. Use a laser head with high temperature resistance, but it is expensive, and generally only used by customers with special requirements or front-mounted; 2. Use micro-fans to dissipate heat. Most of the high-end car audio have adopted this kind of solution, the cooling is obvious, but the price is also high, and it also produces noise and dust

Abstract

The invention discloses a car audio, comprising a top cap, a power amplifier unit, a movement unit and a servo unit. The servo unit is arranged at the side of the movement unit and is vertical to the top cap and the power amplifier unit, so that heat produced by a heating device on the servo unit can not radiate to a laser head or the interior of a host. Heat dispersion is good, and the temperature in the interior of the host is low, thus slowing down ageing of the laser head and other electronic devices and prolonging the service life of car audio.

Description

technical field [0001] The invention relates to a vehicle entertainment device, in particular to a vehicle audio system. Background technique [0002] In the current car audio, one of the most common problems is the aging of the laser head, resulting in the phenomenon of not reading discs, which shortens the normal service life of the car audio. Wherein the reasons that make the laser head and other electronic devices aggravate the aging are as follows: the servo board 101 is placed below the movement 102 or the servo board circuit is moved to the main board 103 and below the movement 102, such as figure 1 shown. 105 above the servo circuit is the active area of ​​the laser head. According to the principle of upward flow of heat, the heat generated by the decoding, driving, and power management ICs on the servo board gathers in the laser head area, causing the temperature around the laser head to rise. Behind the laser head is the heat sink 104 of the power amplifier. Sinc...
