Example 1

FIG. 1 is a schematic diagram of a wireless headset 1 , a first terminal 2 , and a second terminal 3 according to an embodiment of the present application. As shown in FIG. 1 , the wireless headset 1 of this embodiment includes:

a first wireless transceiver 101, where the first wireless transceiver 101 is configured to perform wireless communication with the first terminal 2 based on a first communication protocol;

A second wireless transceiver 102, the second wireless transceiver 102 is configured to perform wireless communication with the second terminal 3 based on a second communication protocol, where the second communication protocol is different from the first communication protocol.

Wherein, the types of the wireless earphones 1 may be various, for example, the types of the wireless earphones 1 may be ordinary wireless earphones 1 or true wireless stereo (True Wireless Stereo, TWS) earphones and the like.

The specific form of the wireless earphone 1 can be determined according to actual needs.

For example, in daily use, a user may use a pair of paired earphones, the paired earphones include a left earphone and a right earphone, and the wireless earphone 1 in the embodiment of the present application may be the paired earphones That is to say, the wireless earphone 1 can be the left earphone or the right earphone in a pair of paired earphones, and there is another wireless earphone 4 paired with the wireless earphone 1, and the wireless earphone 1 can Information is transmitted through wireless communication with other matching wireless earphones 4 without setting up a wired connection. The functions of other wireless earphones 4 paired with the wireless earphones 1 may be the same as the wireless earphones 1, or may be different.

Of course, in some cases, the wireless earphone 1 can be used alone in the form of a left earphone or a right earphone without pairing with other wireless earphones 4 .

In addition, the specific structure of the wireless earphone 1 can also be determined according to specific scene requirements, which is not limited here.

For example, in addition to the first wireless transceiver 101 and the second wireless transceiver 102, the wireless headset 1 may also include other components. For example, it may include one or more components of a control chip 103, a casing, a headphone button (such as a mechanical button or a touch button), a microphone 108, a speaker 109, an antenna 104, a battery, and the like. The earphone button may have a raised part on the surface of the wireless earphone 1 to facilitate user contact, and the earphone button may have one or more; and components such as the microphone 108, the control chip 103, the speaker 109, the antenna 104 and the battery can be Installed inside the housing. In some embodiments, the wireless headset 1 may include a control chip 103, and the control chip 103 may be used to control the wireless headset 1 to perform wireless communication through the first wireless transceiver 101 and/or through the wireless The transceiver 102 communicates wirelessly.

The first wireless transceiver 101 may perform one-way or two-way information transmission with the first terminal 2 based on the first communication protocol. The first communication protocol may be a general protocol or a standard communication protocol, for example, may be a Bluetooth transmission protocol or the like. Exemplarily, the first terminal 2 may be, for example, a mobile phone, a tablet computer, a desktop computer, a wearable device, and the like.

The second wireless transceiver 102 may perform one-way or two-way information transmission with the second terminal 3 based on the second communication protocol. The second communication protocol may be different from the first communication protocol, that is, the channel bandwidth or communication frequency band of the second communication protocol may be different from the first communication protocol. In some examples, the second communication protocol may be a proprietary communication protocol, and may also be referred to as a custom communication protocol. Different from the standard communication protocol, the protocol specification of the private communication protocol is often a self-defined specification, and the specific content of the second communication protocol can be set by the research and development personnel, so that it can often be more concise than the standard communication protocol. The transmission delay of the wireless transmission performed by the proprietary communication protocol is often very low, so that ultra-low delay wireless transmission can be realized. If the second communication protocol is a proprietary communication protocol, the second communication protocol may be pre-deployed in the second terminal 3 . Exemplarily, the second terminal 3 may be a wireless transmitter 5 or the like. In some examples, the second terminal 3 may also be electrically connected to the other terminal, and at this time, the other terminal may wirelessly communicate with the wireless headset 1 through the second terminal 3 .

The specific information interaction mode between the wireless headset 1 and the first terminal 2 and the second terminal 3 can be based on the type of the wireless headset 1 and the type of the first terminal 2 and the second terminal 3 to make sure.

In some embodiments, the first communication protocol is a Bluetooth communication protocol, the second communication protocol is a proprietary communication protocol, the second terminal 3 is a wireless transmitter 5, and the wireless transmitter 5 is used to communicate with all The first terminal 2 is electrically connected.

In the embodiment of the present application, the channel bandwidth of the private communication protocol may be different from that of the Bluetooth communication protocol, so as to avoid mutual interference between information flows. The communication frequency band of the private communication protocol may be the same as or different from the Bluetooth communication protocol. In some examples, both the first communication protocol and the Bluetooth communication protocol are in the 2.4 GHz frequency band.

Among them, since the private communication protocol does not need to set up a large-scale protocol stack and complex transmission standards, generally speaking, the delay of wireless communication based on the private communication protocol is often small, so that ultra-low delay data transmission can be realized. .

In some examples, the wireless transmitter 5 may be a portable device. At this time, the wireless transmitter 5 can be easily carried by the user, and is used for electrical connection with the first terminal 2 , so that the first terminal 2 can pass between the wireless transmitter 5 and the wireless headset 1 . Wireless communication is performed in a second communication protocol. It can be seen that if the second terminal 3 is the wireless transmitter 5, in the wireless connection mode based on the first communication protocol, the first terminal 2 can communicate with the wireless transmitter through the first wireless transceiver 101 The headset 1 transmits information; and in the wireless connection mode based on the second communication protocol, the first terminal 2 can communicate with the wireless headset 1 through the wireless transmitter 5 and the second wireless transceiver 102 Information transfer. At this time, when performing operations such as online games and online live broadcasts through the wireless headset 1 and the first terminal 2, the wireless transceiver can be used to realize the communication between the wireless headset 1 and the first terminal 2.
