Technical Field
The utility model relates to an electricity communication technical field, especially a smart mobile phone function extension equipment based on raspberry group.
Background
Along with the popularization of wireless communication equipment, especially smart phones, people's life and entertainment ways have also changed greatly. In daily life, the smart phone device is used for watching media files, particularly watching movies, watching TV plays and listening to music, which is one of the most important life and entertainment ways of people. However, the smart phone is limited by the influences of the size, power, cost and the like of the smart phone, most smart phones are only provided with one loudspeaker, if a better video watching experience is required, left and right sound channels are required to be output simultaneously, obviously, the single loudspeaker of many smart phones cannot achieve the effect, the sound of most of the loudspeakers is not flood enough, the user experience is poor, and the requirement of people on the video watching experience cannot be met.
In addition, not only apple smart phones, but also many smart phones based on the android system cancel the memory card expansion function, and use a ROM (read only memory) with a larger capacity, but the mobile phones with the large capacity ROM are generally higher in price, so that users are difficult to buy products meeting the use requirements of the users at a low price.
Therefore, there is a need to develop and design an expansion device which is small in size, portable, capable of improving the audio output quality of the smart phone and capable of expanding the memory of the smart phone.
