Abstract
The utility model discloses a music sharing mobile terminal, which comprises a case, a main board, a microprocessing controller and a memory, wherein the microprocessing controller is provided with an audio frequency processing unit in an integrated way. The utility model is characterized in that the music sharing mobile terminal comprises a frequency modulation (FM) wireless emitting device arranged on the main board, wherein the frequency modulation (FM) wireless emitting device is connected with the microprocessing controller through a circuit. The music share mobile terminal provided by the utility model has the advantages that the music sharing of the mobile terminal can be realized through receiving frequency modulation signals sent by the mobile terminal as long as searching or finding the frequency band of the frequency modulation signals no matter the mobile terminal is the mobile terminal with the FM radio function or the frequency modulation radio. Because the frequency modulation signal transmission distance is long, in addition, the number of receiving parties is not limited, and the music sharing function can be perfectly realized.
Description
Technical field
The utility model relates to a kind of music sharing portable terminal.
Background technology
Along with the development of electronic communication, the function of portable terminal is more and more diversified, listens to the music by more and more user-selected with portable terminal, and the music data that oneself is kept in the portable terminal is shared with other people, becomes one of demand of user.Common music sharing mobile phone in the prior art mainly is provided with bluetooth module on the mainboard of portable terminal, rely on Bluetooth technology to realize the mutual transmission of music data.This mode though also can carry out music sharing easily between portable terminal, is lost owing to have signal in the process that Bluetooth signal transmits in air, has limited the distance between portable terminal greatly.In addition, Bluetooth signal as runs into barriers such as wall in transmission course, the reflection of solid can take place, and has further increased losing of signal.Like this, utilize portable terminal to realize that the function of music sharing has been subjected to the very big restriction on the space.
The utility model content
In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of portable terminal that utilizes FM signal to realize the music wireless sharing functionality.
Above-mentioned music sharing portable terminal, comprise shell, mainboard, integrated microprocessor controller, the memory that is provided with audio treatment unit, it is characterized in that: also comprise frequency modulation (FM) wireless launcher that is arranged on the mainboard, described frequency modulation (FM) wireless launcher is connected with described microprocessor controller circuit.
Music sharing portable terminal provided by the utility model, no matter be the portable terminal that has FM receiver function, or FM receiver, as long as search for or find out the residing frequency range of this FM signal, just can receive the FM signal that this portable terminal sends, realize the music sharing of described portable terminal.Because the frequency-modulated signal transmission distance, and recipient's quantity is unrestricted, can better realize the function of music sharing
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 utilizes the utility model to realize the schematic flow sheet of music sharing.
Embodiment
As shown in Figure 1, a kind of music sharing portable terminal, comprise shell, mainboard, integrated microprocessor controller, the memory that is provided with audio treatment unit, it is characterized in that: also comprise frequency modulation (FM) wireless launcher that is arranged on the mainboard, described frequency modulation (FM) wireless launcher is connected with described microprocessor controller circuit.Described frequency modulation (FM) wireless launcher is used to receive the stereo audio signal of described microprocessor controller transmission and this stereo audio signal is handled back emission FM signal.Like this, no matter be the portable terminal that has FM receiver function, or FM receiver, as long as search for or find out the residing frequency range of this FM signal, just can receive the described FM signal that this portable terminal sends, realize the music sharing of described portable terminal.Because the frequency-modulated signal transmission distance, and recipient's quantity is unrestricted, can better realize the function of music sharing.
Be illustrated in figure 2 as described music sharing portable terminal and realize the schematic flow sheet of music sharing.As long as the recipient has wireless function, with regard to the frequency range of this music sharing portable terminal of energy, stereo audio signal sends with the form of FM broadcasting; If the recipient knows the frequency range of this music sharing portable terminal, directly import this frequency range, can be convenient receive audio signal.
