Further,
The cell-phone cover is cortical material or rubber material.
Further,
There is an inner cavity, the loudspeaker are arranged described interior intracavitary and convex to the outer surface of cell-phone cover in the cell-phone cover
Out, a sound equipment is formed.
Further,
The metal contact piece is two.
Further, the sound quality evaluating apparatus includes: mobile phone master chip, audio frequency power amplifier chip and built-in loudspeaker, spy
Sign is: the system also includes switching group and external evaluated end, the switching group, include: first switch, second switch
It is switched with third, the input terminal of the output end of the mobile phone master chip and the audio frequency power amplifier chip is electrically connected, the audio
The output end of power amplifier chips and the first switch are electrically connected, and the input terminal and the second switch of the built-in loudspeaker are electrical
Connection, the external evaluated end and third switch are electrically connected, between the first switch and third switch
Electrical connection between electrical connection, the second switch and third switch is controlled by main control module.
Compared with prior art, the utility model has the beneficial effects that having the advantages that structure is simply and vdiverse in function.
