Anti-jamming wireless microphone

Abstract

The invention provides an anti-jamming wireless microphone which comprises a microphone body (1). The wireless microphone is characterized in that a sound pick-up (2) is arranged on the upper end of the microphone body (1); the output end of the sound pick-up (2) is connected with the input end of an audio pick-up circuit (3); the output end of the audio pick-up circuit (3) is connected in series with a primary amplifier circuit (4) and a secondary amplifier circuit (5); the secondary amplifier circuit (5) is connected with an amplitude modulated wave oscillator (6); the amplitude modulated wave oscillator (6) is connected with a transmitting module (7); and a direct current power supply is connected with the sound pick-up (2), the audio pick-up circuit (3), the amplitude modulated wave oscillator (6) and the transmitting module (7). According to the invention, the anti-jamming wireless microphone has the advantages of high integration and small overall volume; through multi-stage signal amplification and amplitude modulated wave oscillation, the sound amplification effect is improved; the output sound quality effect of sound amplification is optimized; the anti-jamming performance is improved; and the use range is wide.

Description

technical field [0001] The invention relates to a wireless microphone, in particular to an anti-jamming wireless microphone, which belongs to the technical field of sound amplifying equipment. Background technique [0002] At present, the wireless microphones used by people have a large overall volume, low integration of internal components, poor sound amplification effect and output sound quality, poor anti-interference performance, and inconvenient use. Contents of the invention [0003] The purpose of the present invention is to solve the defects and deficiencies of the currently used wireless microphones, which have large overall volume, poor sound amplification effect and output sound quality, and poor anti-interference performance. And the sound quality of the sound output by the loudspeaker has been improved, the anti-interference performance has been improved, and it is an anti-interference wireless microphone which is very convenient to use. [0004] To achieve t...
