Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] Such as figure 1 As shown, the wireless handheld microphone of the present invention comprises a pick-up head, an audio circuit and a microphone circuit connected in sequence; it is characterized in that: it also includes an acceleration sensing circuit, and the acceleration sensing circuit includes an acceleration sensor and a processing circuit; the acceleration sensor It is connected with the microphone circuit through the processing circuit. Among them, the pick-up head, the audio circuit and the microphone circuit are not the improvement points of the present invention, and can be implemented by using existing related circuits, so no more details are given here. The acceleration sensor is used to detect whether there is a change in the acceleration of the microphone, so as to judge whether the microphone is picked up, hel...

The invention provides a wireless handheld microphone. The wireless handheld microphone comprises a sound head, a voice-frequency circuit and a microphone circuit, wherein the sound head, the voice-frequency circuit and the microphone circuit are sequentially connected. The wireless handheld microphone is characterized by further comprising an acceleration sensing circuit. The accelerated speed sensing circuit comprises an acceleration sensor and a processing circuit. The acceleration sensor is connected with the microphone circuit through the processing circuit. According to the wireless handheld microphone, the acceleration sensor senses whether the microphone is in a handheld state, so that automatic start-up or power close-down of the microphone is controlled, effective and stable working voltage is provided for the microphone, the energy consumption of the microphone is effectively lowered, and the service life of the microphone is prolonged.
Description
technical field [0001] The invention relates to a wireless hand-held microphone, in particular to a wireless hand-held microphone with automatic switch. Background technique [0002] Microphone, as a kind of electroacoustic equipment, is widely used in schools, courts, government agencies, conference rooms and KTV and other occasions. At present, the wireless handheld microphones on the market all use buttons to control the power on and off of the microphone. Every time it is turned on and off, it is necessary to manually press the button to operate. The user often does not turn off the microphone when putting down the microphone, but keeps the microphone on. This will cause unnecessary energy consumption, cause energy waste and shorten the battery life. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a wireless handheld microphone that can be switche...
