Abstract

The invention discloses a wireless recording apparatus. The wireless recording apparatus comprises a recording master machine and a sound source slave machine. The recording master machine comprises a microprocessor, a master machine wireless communication unit connected with the microprocessor, and a memory. The sound source slave machine comprises a signal conversion module, a slave machine microphone connected with the signal conversion module, and a slave machine wireless communication unit. The master machine wireless communication unit of the recording master machine establishes a wireless communication channel with the slave machine wireless communication unit of the sound source slave machine, and the master machine wireless communication unit receives sound source signals of the sound source slave machine and transmits the sound source signals to the microprocessor for processing and generating wireless recording data for storage in the memory. According to the invention, through the wireless communication channel established by the master machine wireless communication unit of the recording master machine and the slave machine wireless communication unit of the sound source slave machine, the recording master machine receives the sound source signals of the sound source slave machine in a wireless transmission communication mode and processes and generates the recording data, such that far-distance recording at a large pace is greatly facilitated, the recording quality is guaranteed, and the popularization and application are facilitated.

Description

【Technical field】 [0001] The invention relates to a recording device, in particular to a wireless recording device which facilitates wireless connection to realize long-distance recording. 【Background technique】 [0002] The recording device is used to record the sound of the scene, such as the speech of the meeting, etc., and save the content of the speech, which is convenient for recall and search. Due to the situation of different conference venues, in a small meeting room, the recording device can record the content of the meeting. However, in a large conference venue, if the recording device is far away from the speaker, coupled with the interference of other sound sources in the venue, it will directly It affects the recording effect, and even the recording is unclear and difficult to recognize, which undoubtedly loses the value of the recording. [0003] Therefore, if it is possible to provide a recording device that is convenient for recording at a relatively long d...
