Embodiment Construction

[0015] Embodiments of the present invention will be described below in conjunction with related figures. In the drawings, the same reference numerals indicate the same or similar components or method flows.

[0016] figure 1 It is a simplified functional block diagram of the multi-member Bluetooth device 100 according to an embodiment of the present invention. The multi-member Bluetooth device 100 is used for data transmission with a source Bluetooth device 102 and includes multiple member circuits. For convenience of explanation, in figure 1 In the embodiment of FIG. 2 , only two member circuits are shown, which are the main Bluetooth circuit 110 and the secondary Bluetooth circuit 120 .

[0017] In this embodiment, all member circuits in the multi-member Bluetooth device 100 have a similar main circuit structure, but different additional circuit components can be set in different member circuits, and it is not limited to the circuit structure of all member circuits. exac...

Abstract

The invention provides a multi-member Bluetooth device capable of synchronizing audio playback between different Bluetooth circuits. The multi-member Bluetooth device is used for communicating data with a source Bluetooth device, wherein the source Bluetooth device acts as a master in a first piconet. The multi-member Bluetooth device includes a main Bluetooth circuit and an auxiliary Bluetooth circuit. The main Bluetooth circuit acts as a slave in the first piconet, and acts as a master in a second piconet. The auxiliary Bluetooth circuit acts as a slave in the second piconet. The main Bluetooth circuit generates a first slave clock and a second main clock synchronized with a first main clock generated by the source Bluetooth device, and samples a first audio data to be playback. The auxiliary Bluetooth circuit generates a second slave clock and a third slave clock synchronized with the second main clock, and samples a second audio data to be playback.

Description

technical field [0001] The invention relates to the bluetooth technology, in particular to a multi-member bluetooth device which can keep the audio playing of different bluetooth circuits synchronous. Background technique [0002] A multi-member Bluetooth device refers to a Bluetooth device composed of multiple Bluetooth circuits used in conjunction with each other, for example, a pair of Bluetooth headsets, a group of Bluetooth speakers, and the like. When the multi-member Bluetooth device is connected with other Bluetooth devices (hereinafter referred to as remote Bluetooth devices), the remote Bluetooth device will treat the multi-member Bluetooth device as a single Bluetooth device. [0003] Many traditional multi-member Bluetooth devices have audio playback capabilities. In many applications, different Bluetooth circuits may play audio data in concert to create a stereo or surround sound effect. However, if the audio playback operations of different bluetooth circuits...
