Problems solved by technology

[0005] In order to solve the deficiencies in the prior art, the present invention provides a near-field audio transceiver system and transceiver method based on a wireless Mesh network. The execution terminal only has a radio function or a pronunciation function, thereby effectively avoiding the vibration of the speaker from causing the radio frequency of the microphone. impact, and can avoid the wiring difficulties and inconvenient problems caused by wired connections

Embodiment 1

[0025] Such as Figure 1-3 As shown, a near-field audio transceiver system based on a wireless Mesh network includes a host, at least one execution terminal and at least one relay terminal, and the relay terminal is connected to the host and the execution terminal through Bluetooth, so that the system uses the Bluetooth Mesh network For data communication, one relay terminal can connect multiple execution terminals via Bluetooth, and one execution terminal can also connect multiple relay terminals via Bluetooth at the same time.

[0026] The host computer is used to obtain uplink audio signals from the execution terminal, send downlink audio signals to the execution terminal, and send control signals to the execution terminal.

[0027] The executive terminal includes the radio function or the pronunciation function, and each executive terminal only includes one kind of function. When the execution terminal performs the sound collection function, it is used to collect the firs...

Embodiment 2

[0048] Based on Embodiment 1, the present invention also provides an extended system. The extended system may include multiple hosts, and multiple hosts, multiple relay terminals, and multiple execution terminals may form a mesh network of several hosts. Such as figure 2 As shown, in the mesh network of multiple hosts, the sending and receiving method of this embodiment is roughly the same as that of Embodiment 1, except that multiple hosts can output control signals in parallel, that is, the following steps are different:

[0049] Step 1.2. Multiple hosts generate query data packets and broadcast the query data packets to all relay terminals. After the relay terminals are powered on and started, they use scanning mode to receive information. After receiving the query data packets, the relay terminals feed back address information to All hosts, and then all hosts generate a first-level linked list, which includes the host itself, other hosts, and relay terminals connected to ...

Abstract

A near-field audio transceiver system based on a wireless Mesh network, including at least one host, at least one execution terminal and at least one relay terminal; the host is used to obtain uplink audio signals from the execution terminal, send downlink audio signals to the execution terminal, and send The terminal sends a control signal; when the terminal executes the radio function, it is used to collect the first sound and convert the first sound into an uplink audio signal, and then sends the uplink audio signal to the host; when the terminal executes the pronunciation function, it is used to obtain the downlink audio from the host signal and convert the downlink audio signal into a second sound, and then emit the second sound; the relay terminal is used to forward the uplink audio signal, downlink audio signal and control signal between the host and the execution terminal. In the present invention, the execution terminal only has the sound collection function or the pronunciation function, which effectively avoids the influence of the vibration of the speaker on the sound collection of the microphone, and can avoid the problems of difficult routing and inconvenient use caused by wired connections.

Description

technical field [0001] The present invention relates to the technical field of audio transceiving, in particular to a near-field audio transceiving system and transceiving method based on a wireless Mesh network. Background technique [0002] At present, in the field of audio transmission and reception, the difficulty of receiving audio is generally greater than that of emitting audio, especially in near-field radio, the existence of echoes leads to poor radio reception, because the sensitivity of the microphone is very high, as long as there is a little sound, it can be heard Income, that is, in addition to the sound source itself, the echo part is also included, which leads to a lot of noise in the income audio. [0003] In the prior art, two methods are mainly used to overcome the high noise of near-field radio. One is to use the echo algorithm to eliminate noise, but because the echo algorithm is mostly very complex, the performance requirements of the hardware device a...
