Abstract

The invention relates to the technical field of Bluetooth communication. The invention discloses Bluetooth communication equipment for audio playing and audio forwarding, a group and an audio playingand forwarding method thereof. The Bluetooth communication equipment comprises a Bluetooth communication unit; a first Bluetooth chip which is used for establishing a first Bluetooth communication link with the front-end communication equipment; a second Bluetooth chip which is used for establishing a second Bluetooth communication link with rear-end communication equipment; a first sound mixing circuit which is used for carrying out sound mixing processing on the audio data received by the second Bluetooth chip and the audio data acquired by the microphone; a second sound mixing circuit whichis used for carrying out sound mixing processing on the audio data received by the first Bluetooth chip and an audio signal acquired by the microphone; and the plurality of Bluetooth communication devices form a multi-stage series Bluetooth communication link. According to the invention, a plurality of Bluetooth communication devices can be connected, the number of the Bluetooth communication devices is not limited, a communication protocol does not need to be developed privately, the connection of the Bluetooth communication devices is orderly, and the call and voice forwarding among the Bluetooth communication devices is realized.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a bluetooth communication device for audio playback and forwarding, a communication method and a group thereof. Background technique [0002] With the development and continuous promotion of Bluetooth technology, the application range and application fields of Bluetooth headsets are also expanding. At present, the Bluetooth headset technology is limited to the audio communication between the mobile phone and the Bluetooth headset, and there are no products on the market that can realize serial communication between multiple devices such as mobile phones and Bluetooth headsets, and Bluetooth headsets and Bluetooth headsets. However, this product has a greater demand in the market. [0003] China has the largest market for two-wheeled electric vehicles and motorcycles. How to answer the phone while driving two-wheeled electric vehicles or motorcycles has become an ...
