Example one

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 invention. As shown in fig. 1, the wireless headset 1 of this embodiment includes:

a first wireless transceiver 101, said first wireless transceiver 101 being adapted to wirelessly communicate with a first terminal 2 based on a first communication protocol;

a second wireless transceiver 102, said second wireless transceiver 102 being adapted to wirelessly communicate with a second terminal 3 based on a second communication protocol, said second communication protocol being different from said first communication protocol.

The type of the Wireless headset 1 may be various, for example, the type of the Wireless headset 1 may be a general Wireless headset 1 or a True Wireless Stereo (TWS) headset, and the like.

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

For example, in daily use, a user may use a pair of paired earphones, which includes a left earphone and a right earphone, and the wireless earphone 1 in the embodiment of the present invention may be one of the paired earphones, that is, the wireless earphone 1 may be the left earphone or the right earphone of the pair of paired earphones, and there is another wireless earphone 4 paired with the wireless earphone 1, and the wireless earphone 1 may perform information transmission with the other matched wireless earphone 4 through wireless communication without providing a wired connection. The functions of the other wireless earphones 4 paired with the wireless earphone 1 may be the same as or different from the wireless earphone 1.

Of course, in some cases, the wireless headset 1 may be used alone in the form of one left or right headset without pairing with other wireless headsets 4.

In addition, the specific structure of the wireless headset 1 may also be determined according to specific scene requirements, and is not limited herein.

For example, other components may be included in the wireless headset 1 in addition to the first wireless transceiver 101 and the second wireless transceiver 102. For example, one or more of the control chip 103, the housing, the earpiece keys (e.g., mechanical keys or touch keys), the microphone 108, the speaker 109, the antenna 104, and the battery, among others, may be included. The earphone keys may have a raised portion on the surface of the wireless earphone 1 for easy contact by a user, and may have one or more earphone keys; and the microphone 108, the control chip 103, the speaker 109, the antenna 104, and the battery may be mounted inside the housing. In some embodiments, the wireless headset 1 may comprise a control chip 103, and the control chip 103 may be configured to control the wireless headset 1 to communicate wirelessly via the first wireless transceiver 101 and/or to communicate wirelessly via the wireless transceiver 102.

The first wireless transceiver 101 may be capable of unidirectional or bidirectional information transfer with the first terminal 2 based on the first communication protocol. The first communication protocol may be a general protocol, or may be considered as a standard communication protocol, for example, a bluetooth transmission protocol. Illustratively, the first terminal 2 may be a mobile phone, a tablet computer, a desktop computer, a wearable device, and the like.

The second wireless transceiver 102 may perform a one-way or two-way information transfer 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, a channel bandwidth or a 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, which 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 research personnel, so that the private communication protocol is often simpler than the standard communication protocol, the transmission delay of wireless transmission through the private communication protocol is often very low, and the wireless transmission with ultra-low delay can be realized. If the second communication protocol is a private communication protocol, the second communication protocol may be pre-deployed in the second terminal 3. Illustratively, 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 with the other terminal, and in this case, the other terminal may wirelessly communicate with the wireless headset 1 through the second terminal 3.

The specific information interaction mode of the wireless headset 1 with the first terminal 2 and the second terminal 3 may be determined according to the type of the wireless headset 1 and the types of the first terminal 2 and the second terminal 3.

In some embodiments, the first communication protocol is a bluetooth communication protocol, the second communication protocol is a private communication protocol, and the second terminal 3 is a wireless transmitter 5, the wireless transmitter 5 being configured to electrically connect with the first terminal 2. In the embodiment of the present invention, the channel bandwidth of the private communication protocol may be different from the bluetooth communication protocol, so as to avoid mutual interference between information streams. The communication frequency band of the private communication protocol may be the same as or different from the bluetooth communication protocol. In some examples, the first communication protocol and the bluetooth communication protocol are both in the 2.4GHz band.

Since the private communication protocol does not need to set a large-scale protocol stack and a complicated transmission standard, generally, the delay of wireless communication based on the private communication protocol is often small, and thus, data transmission with ultra-low delay can be realized.

In some examples, the wireless transmitter 5 may be a portable device. At this time, the wireless transmitter 5 may be conveniently carried by a user and used to electrically connect with the first terminal 2, so that the first terminal 2 can perform wireless communication with the wireless headset 1 through the wireless transmitter 5 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 perform information transmission with the wireless headset 1 through the first wireless transceiver 101; in the wireless connection mode based on the second communication protocol, the first terminal 2 can perform information transmission with the wireless headset 1 through the wireless transmitter 5 and the second wireless transceiver 102. At this time, when operations such as online gaming, online live broadcasting, and the like are performed through the wireless headset 1 and the first terminal 2, ultra-low-delay data transmission between the wireless headset 1 and the first terminal 2 may be achieved through the wireless transceiver, so that the use experience of the user may be improved.

A specific implementation of the embodiments of the present invention is schematically illustrated below by a specific example.

Fig. 2 is a schematic diagram of an information interaction manner between the wireless headset 1 and the first terminal 2.

As shown in fig. 2, in one example, the first terminal 2 may be a mobile phone. There may be other wireless earphones 4 paired with the wireless earphone 1, where the wireless earphone 1 may be a right earphone, the other wireless earphones 4 may be left earphones, and the functions of the other wireless earphones 4 may be the same as the wireless earphone 1. Wherein, for the convenience of wearing, the structure of the other wireless earphone 4 may be symmetrical to the structure of the wireless earphone 1.

The wireless headset 1 and the other wireless headsets 4 can be stored in a storage box when not in use.

After the wireless headset 1 and the other wireless headset 4 paired with the wireless headset 1 are taken out from the storage box, the wireless headset 1 and the other wireless headset 4 can both wirelessly communicate with a mobile phone through a bluetooth communication protocol (i.e., the first communication protocol in this example) to transmit audio data, for example, the mobile phone can transmit audio corresponding to video and audio received through a cellular network during a call to the wireless headset 1 and/or the other wireless headset 4, and the wireless headset 1 and/or the other wireless headset 4 can transmit audio received by the microphone 108 of the mobile phone.

By the switch 105, the antenna 104 can be controlled to be electrically connected with the second wireless transceiver 102 or the antenna 104 can be controlled to be electrically connected with the first wireless transceiver 101. In this case, the switch 105 may control the connection state and the disconnection state of the first wireless transceiver 101 and the second wireless transceiver 102 with respect to the antenna 104 by a control strategy such as time division multiplexing, so as to conveniently control the wireless communication method adopted when the wireless headset 1 performs wireless communication. In addition, the first wireless transceiver 101 and the second wireless transceiver 102 may share one antenna 104, so as to improve the compactness of the structure of the wireless headset 1, reduce the hardware cost, and reduce the volume of the wireless headset 1.
