Description

Smartphone function expansion equipment based on raspberry group
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.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a simple structure, low in production cost's smart mobile phone function extension equipment based on raspberry group.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a smart mobile phone function extension equipment based on raspberry group, includes power module and extension module, power module with the extension module electricity is connected, the extension module is connected with the smart mobile phone communication.
The extension module comprises an SD card, a first loudspeaker, a second loudspeaker and a raspberry group chip controller, the power module, the SD card, the first loudspeaker and the second loudspeaker are all electrically connected with the raspberry group chip controller, and the raspberry group chip controller is in communication connection with the smart phone.
The raspberry pi chip controller comprises a Central Processing Unit (CPU), a Bluetooth chip and an interface module, wherein the interface module and the Bluetooth chip are electrically connected with the CPU.
The utility model has the advantages that: the utility model discloses through establish with the smart mobile phone and be connected, separately export the audio frequency of smart mobile phone output with left and right sound channel through extension module, solved the smart mobile phone can only the single disadvantage of sound channel output, optimized and used experience; in addition, a certain amount of storage space is arranged in the extension module, a user can paste or transfer files in the intelligent mobile phone to the internal storage space of the extension module, more files can be stored in the equipment carried by the user, the practicability of the product is effectively improved, and the intelligent mobile phone has the advantages of being simple in structure, small in size, low in production cost and the like.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a block diagram illustrating the structure of the present invention;
FIG. 2 is a flow chart of the present invention;
fig. 3 is a block diagram of the raspberry pi chip controller of the present invention.
Detailed Description
Referring to fig. 1 to 3, the smart phone function expansion device based on the raspberry pi comprises a power module 1 and an expansion module 2, wherein the power module 1 is electrically connected with the expansion module 2, and the expansion module 2 is in communication connection with a smart phone 3.
In this embodiment, the expansion module includes an SD card 5, a first speaker 6, a second speaker 7, and a raspberry pi controller 8, the power module 1, the SD card 5, the first speaker 6, and the second speaker 7 are all electrically connected to the raspberry pi controller 8, the raspberry pi controller 8 is communicatively connected to the smart phone 3, further, the raspberry pi controller includes a central processing unit CPU, a bluetooth chip, and an interface module, and the interface module and the bluetooth chip are both electrically connected to the central processing unit CPU; in this embodiment, the central processing unit CPU is configured to receive an audio output by the smart phone, and communicate with the smart phone through the bluetooth chip; the interface module comprises a GPIO (general purpose input/output) interface, a MINIHDI (Micro-high definition multimedia interface), a Micro usb data interface and a Micro usb power supply interface, the power module 1 is a battery 4, the power module 1 supplies power to a Central Processing Unit (CPU) through the Micro usb power supply interface, the first loudspeaker 6 and the second loudspeaker 7 are electrically connected with the CPU through the GPIO interface, when the raspberry pi controller 8 is connected with the smart phone 3 in a matched mode, the raspberry pi controller 8 outputs received audio from the GPIO interface, and outputs audio output by the smart phone 3 in the form of a left channel and a right channel through the first loudspeaker 6 and the second loudspeaker 7 respectively, and the MINI HDMI interface and the Micro usb data interface are used for providing video input connection and data transmission for the raspberry pi chip controller 8; in this embodiment, the raspberry pi controller 8 further includes a memory card slot for assembling the SD card 5, in this embodiment, a user can directly access a file in the SD card 5 of the raspberry pi controller 8 through a file manager of the smart phone 3, and can also copy or transfer a file stored inside the smart phone 3 to the SD card 5 through a bluetooth chip, so that the smart phone 3 carried by the user can store more files, and the practicability of the product is effectively improved; in this embodiment, raspberry group chip controller 8 have the low price, advantages such as small, and the user can design whole extension equipment on less plate body or casing, like cell-phone shell etc to fix extension equipment through modes such as joint or gluing on smart mobile phone 3, conveniently carry the use.
