Abstract
The utility model puts forward a piece of expansion sound equipment for a mobile terminal. The expansion sound equipment for the mobile terminal comprises a sound box and a host, wherein the host is provided with an interface adaptive to the mobile terminal, the host comprises an audio frequency chip and charge control chip which are connected to the interface, the audio frequency chip is connected with the sound box, the charge control chip is connected with an input power source, the host also comprises a main control chip which is connected to the audio frequency chip so as to receive signals from the audio frequency chip, and the main control chip is also connected to the charge control chip so as to control the charge control chip to be disconnected from the input power source when the audio frequency chip is in working processes. The expansion sound equipment for the mobile terminal can be disconnected from the input power source and stops charging when the mobile terminal is played through the expansion sound equipment, and a chip damage problem which is caused when a playing function and a charging function are fulfilled at the same time can be prevented.
Description
Technical field
The utility model relates to electronic technology field, relates in particular to a kind of mobile terminal expansion sound equipment.
Background technology
Mobile terminal, such as smart mobile phone, digital code player etc., all have powerful storage capacity and music playback function, and a lot of people have been accustomed to the use mobile terminal and have listened song.Simultaneously increasing musical works also all starts to be propagated by network, and the user can download to these musical works in mobile terminal very easily.Enjoy music by mobile terminal at home for the ease of the user, a lot of mobile terminal expansion sound equipments also occurred now, this expansion sound equipment all has the interface suitable with mobile terminal, can connect easily mobile terminal.This expansion sound equipment can read the voice data in mobile terminal by this interface, is then play.Existing mobile terminal is not only by these interface transmission data, also by this interface charging, therefore a lot, and the expansion sound equipment can both be also the mobile terminal charging when playing.But existing mobile terminal caloric value when charging is very large, if also play and be easy to cause equipment burnout at the same time.
Summary of the invention
For the defect existed in prior art and deficiency, the purpose of this utility model is to propose a kind of mobile terminal expansion sound equipment.
In order to achieve the above object, the utility model proposes a kind of mobile terminal expansion sound equipment, comprise audio amplifier and main frame, described main frame has the interface suitable with described mobile terminal, described main frame comprises audio chip and charge controlling chip, described audio chip all is connected described interface with charge controlling chip, and described charge controlling chip connects input power, described audio chip connects audio amplifier; Also comprise main control chip, described main control chip connects described audio chip to receive the signal of described audio chip, and described main control chip also connects described charge controlling chip to control described charge controlling chip disconnection input power when described audio chip is worked.
As technique scheme preferably, described charge controlling chip is an electronic switch, the input of described electronic switch connects input power, output connects described interface, and the control end of described electronic switch connects described main control chip.
As technique scheme preferably, the input of described audio chip connects described interface, output connects audio amplifier; Described main control chip connects the output of described audio chip.
The beneficial effect of the technical scheme that the utility model embodiment provides is: the utility model can disconnect input power and stop charging when mobile terminal is play by the expansion sound equipment, prevents the chip damage problem because play and charge and cause simultaneously.
