Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in each claim of the present application can be realized.

The first embodiment of the present invention relates to a music sharing system for wireless card-inserted earphones, as shown in FIG. earphones 2, 3, ..., N); the first type of earphones contains a first memory card, an audio codec, a first wireless transceiver; the second type of earphones contains a second memory card, an audio codec, a second wireless transceiver. It should be noted that in practical applications, the internal structure of the first-type earphones and the second-type earphones are the same, including memory cards, audio codecs, and wireless transceivers, but when music sharing is realized, the first-type earphones send audio signal, while the second type of earphone receives the audio signal.

Audio data is stored in the first memory card. When the user uses the wireless card headset and switches to the card playback mode, the audio data in the memory card can be decoded by the audio codec and the audio signal can be played through the speaker for the user to listen to. . When it is necessary to share music with friends around, the audio data will be transmitted in the form of wireless broadcast signal after being modulated by the first wireless transceiver; within the transmission range of the wireless broadcast signal, the second type of earphone will receive the wireless broadcast through the second wireless transceiver After the signal is demodulated, the audio signal is decoded by the audio codec and played through the speaker. That is to say, after the audio data is modulated by a certain modulation method at the same time, it is transmitted through the wireless transmitter in the form of a wireless broadcast signal, and the same type of wireless plug-in card headsets of friends around are switched to the wireless listening mode, demodulated and played after receiving the wireless signal Come out, thus forming a one-to-many star data network, realizing the real-time music sharing function. In addition, for the convenience of the user's subsequent use, the demodulated audio data can also be stored, that is to say, the second type of earphone will also receive the wireless broadcast signal through the second wireless transceiver, and the demodulated data will be stored in the on the second memory card.

It should be noted that the first memory card and the second memory card may be memory cards in any form, such as SD card, TF card and so on. Audio codecs encode and decode audio data in any format, including mp3, wma, and all other formats. The first wireless transceiver and the second wireless transceiver can be in any form, work in any modulation and demodulation mode, and in any wireless frequency band. Manufacturers of wireless card headsets can decide to use specific memory cards, audio codec formats, modulation and demodulation methods, and wireless frequency bands based on comprehensive consideration of various indicators. These technologies are relatively mature and will not be repeated here.

The audio data transmission between the first-type earphones and the second-type earphones is carried out in the form of unlimited broadcasting, or the audio data transmission is carried out to specific users in the form of restricted authorization of the code. That is to say, when the sharing function is provided, it can be shared in the form of unlimited broadcasting, or it can be shared with specific users in the form of restricted code authorization. Provide users with a variety of audio data transmission forms to meet point-to-point and point-to-multipoint music sharing, which is neither disturbed nor disturbed by others, and significantly improves the utilization of frequency resources.

Compared with the prior art, the wireless card headset in this embodiment modulates the audio data in the memory card and transmits it in the form of a wireless broadcast signal. Within the transmission range of the wireless broadcast signal, other wireless card headsets receive the audio data. After the wireless broadcast signal is demodulated, it is played through the loudspeaker, so that the real-time multi-user music sharing function of the wireless plug-in headset can be realized, and a platform for real-time music appreciation and communication is provided for users.

The second embodiment of the present invention relates to a music sharing method for wireless card-inserted earphones, the flow of which is shown in FIG. 2 , and specifically includes the following steps:

After modulating the audio data stored in the memory card of the wireless card headset, it is transmitted in the form of a wireless broadcast signal;

Within the transmission range of the wireless broadcast signal, the same type of wireless card headset receives the wireless broadcast signal and demodulates it;

Decode the demodulated audio data to obtain an audio signal and play it through the speaker. At the same time, the wireless card headset can also store the demodulated data in its own memory card.

In addition, audio data transmission can be performed between wireless plug-in earphones in the form of unlimited broadcasting, and can also be transmitted to specific users in the form of restricted authorization of the code.

It is not difficult to find that this embodiment is a system embodiment corresponding to the first embodiment, and this embodiment can be implemented in cooperation with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in this embodiment, and will not be repeated here in order to reduce repetition. Correspondingly, the relevant technical details mentioned in this implementation manner can also be applied in the first implementation manner.

The division of steps in the above method is only for the sake of clarity of description. During implementation, it can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they contain the same logical relationship, they are all within the scope of protection of this patent; Adding insignificant modifications or introducing insignificant designs to the algorithm or process, but not changing the core design of the algorithm and process are all within the protection scope of the patent.

Those of ordinary skill in the art can understand that the above-mentioned embodiments are specific examples for realizing the present invention, and in practical applications, various changes can be made to it in form and details without departing from the spirit and spirit of the present invention. scope.
