Problems solved by technology
When the microphone is set on the steering wheel 30 of the car in Figure 1, the following problems will be encountered: the wiring harness on the steering wheel needs to be connected with the wiring harness of the whole vehicle through the clock spring. Since the clock spring cannot be shielded, the microphone is installed on the steering wheel will be subject to electromagnetic interference
[0004] In short, in the prior art, the best sound collection effect cannot be achieved because the microphone cannot be set at the best position

Description
technical field [0001] The invention relates to automobile electronic technology, in particular to a steering wheel integrating a wireless microphone. Background technique [0002] Existing cars are often equipped with a bluetooth phone system, wherein the microphone for receiving sound signals is connected to the bluetooth module through a transmission line. Due to the complex electromagnetic environment in the car, in order to avoid the interference of electromagnetic signals, it is necessary to use shielded wires as transmission lines. However, the bulk of the shielding wire itself is relatively large, so that its installation location is greatly restricted. For example, it can only be arranged in places such as the center console, instrument panel, and ceiling reading lights. [0003] Fig. 1 is a schematic diagram of the layout of a prior art car phone device in a car. Referring to FIG. 1 , the microphone can be placed on the Bluetooth device 10 or on the dashboard 20 ...
