Abstract

The invention discloses an anti-burglary multi-functional car sound system and the portable network digital audio format player. The sound system includes two parts: a primary part and a fixing part, the primary part is the control center of the whole system, and which is a movable part that it can be connected or separated with the car sound fixing part; the fixing part is sound device fixed on the car, the primary part and the fixing part are connected to communication connector arranged on the two parts. When the primary control part is separated form the fixing part, the invention can act anti-burglary function because the primary control part can be separated from the car, and the primary control part becomes a portable network digital audio frequency format player with data memory, it can be used as amusement, and it can be used to store each kind of data.

Description

technical field [0001] The invention relates to a car audio system and its network digital audio format player, in particular to an anti-theft network digital audio player car audio system and its portable network digital audio format player. Background technique [0002] With the continuous improvement of people's income, the team of car owners is growing day by day, and people's love and concern for car audio are increasing. Music in file formats such as CD and MP3 (Audio Layer III) is played with a CD as a storage medium by a CD reader. Their disadvantage in use is poor shockproof performance. Recording CDs is used as the storage medium for music. Although it has the advantages of large storage capacity, convenience, and low cost, it is limited by the car itself and the driving conditions of the car. Usually, the vibration of the car during driving can easily cause the disk to be unreadable and cause the laser head to wear out. , and even the mechanical damage of the di...
