Problems solved by technology
Operators find it laborious to perform such opening and closing operations until the desired signal channel is selected
On the other hand, there is no wireless communication system including a receiving unit capable of selecting a signal channel in cooperation with a wireless microphone
If a conventional wireless communication system is established in close proximity to each other, such as Figure 11 As shown, the wireless signal output from one of the wireless communication systems tends to interfere with the wireless signal from the other wireless communication system, and thus when the operator erroneously operates the switching element, resulting in the generation of a deteriorated speaker's voice
[0005] Therefore, the previously mentioned conventional wireless communication system constructed as previously mentioned suffers from the problem that the wireless microphone makes it laborious to open and close the cover member before selectively operating the switch element to change the signal channel, and the conventional The wireless receiving unit of one of the wireless communication systems tends to receive the wireless signal transmitted through the wireless microphone of the other conventional wireless communication system, resulting in deterioration of the production rate of the speaker's voice

The invention discloses a kind of wireless microphone, which is used to receive an audio signal and transmit a wireless signal, it can combine an audio operation unit and an output control signal operationally. It includes: modulating device for modulating the wireless signal containing audio signal in order to generate a modulated wireless signal, the modulating device is operational under several operation conditions, and it has several signal channels related to operation condition and permissible for passing wireless signal; the detecting device for detecting the control signal outputted by audio operation unit, the control signal represents the operation condition of the modulating device; and adjustment device for responding the control signal form acoustics operation unit to adjust and modulate the operation condition of the device.
Description
technical field [0001] The present invention relates to a wireless communication system for transmitting and receiving wireless signals carrying voice signals representing the voice of a speaker, and more particularly to a wireless communication system comprising at least one wireless microphone for transmitting wireless signals carrying voice signals signal, and a wireless receiving unit for receiving a wireless signal carrying a voice signal transmitted by a wireless microphone in a local communication area to ensure reliable communication based on channel, gain, and other operating conditions input to the wireless microphone. Background technique [0002] Hitherto, various wireless communication systems of this type have been proposed, and a typical example is shown in FIG. 12 . A conventional wireless communication system is shown in Fig. 12, comprising at least one wireless microphone, used to receive the speaker's voice, while transmitting a wireless signal carrying th...
