The utility model content
The utility model is to provide a kind of portable karaok bluetooth earphone of monitoring with the MIC signal for portable digital product, purposes such as the mobile phone with Bluetooth function, panel computer, laptop computers, can only listen to sound accompaniment to solve when current mobile phone connects the mobile phone Karaoke by bluetooth earphone or wired earphone, can not monitor the difficult problem of user's voice, realize that synchronous monitoring of voice and external sound source sound accompaniment makes it the effect that body faces the KTV scene.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of portable karaok bluetooth earphone of monitoring with the MIC signal, comprise: microphone pickup device, bluetooth module, prime amplifier, reverberation circuit, Karaoke switch, audio-frequency power amplifier, loudspeaker and power circuit module, described microphone pickup device is connected with prime amplifier by the Karaoke switch, described prime amplifier connects reverberation circuit, described reverberation circuit connects audio-frequency power amplifier, and outputs to earphone horn by audio-frequency power amplifier; The microphone pickup device is connected with bluetooth module, for sending voice to bluetooth equipment, the bluetooth equipment source of sound is connected to audio-frequency power amplifier by bluetooth module by sound accompaniment, and audio-frequency power amplifier is connected to earphone horn, described power circuit module is connected with other each circuit, and electric power is provided.
The volume control switch that one control microphone pickup device voice volume preferably, is arranged on described Karaoke bluetooth earphone external shell.
Preferably, also include and there is the reverberation regulator potentiometer of regulating the Karaoke reverberation intensity.
Preferably, described microphone pickup device signal output is divided into two-way, and a road is transmitted into the bluetooth equipments such as mobile phone through bluetooth module, and another road process Karaoke volume switch is to prime amplifier.
Preferably, there are charging circuit and rechargeable battery, peripheral hardware charging inlet and power switch in power circuit module the inside.
The utility model compared with prior art, beneficial effect is: the portable karaok bluetooth earphone of monitoring with the MIC signal that the utility model provides, setting up other bluetooth equipments such as mobile phone is connected with the Bluetooth matching between bluetooth earphone, and by prime amplifier and the reverberation circuit be arranged in bluetooth earphone, the people's sound audio signals by the input of microphone pickup device is carried out to reverberation amplification processing, output to loudspeaker by power amplifier chips afterwards, realized that voice and external sound source sound accompaniment synchronously monitor, experience the spot effect of KTV, go to which where is sung, be that amusement oneself does not affect again others, guaranteed audio, avoided the problem that causes song to be difficult to not hear because environment is noisy.
The accompanying drawing explanation
The theory diagram of the portable karaok bluetooth earphone that Fig. 1 is the monitoring of the utility model band MIC signal.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 1 the theory diagram of the portable karaok bluetooth earphone that Fig. 1 is the monitoring of the utility model band MIC signal.The utility model provides a kind of portable karaok bluetooth earphone of monitoring with the MIC signal, can only listen to sound accompaniment to solve when other bluetooth equipments such as current mobile phone connect the mobile phone Karaoke by bluetooth earphone or wired earphone, can not monitor the difficult problem of user's voice, realize that synchronous monitoring of voice and external sound source sound accompaniment makes it the effect that body faces the KTV scene, connects by Bluetooth pairing between other bluetooth equipment such as described mobile phone and the utility model bluetooth earphone.
The utility model comprises: the microphone pickup device, bluetooth module, prime amplifier, reverberation circuit, the Karaoke switch, audio-frequency power amplifier, loudspeaker, the power circuit module, wherein said microphone pickup device is connected with prime amplifier by the Karaoke switch, prime amplifier connects reverberation circuit, reverberation circuit connects the audio-frequency power amplifier power stage to loudspeaker, the microphone pickup device connects bluetooth module and voice is sent to the bluetooth equipments such as mobile phone, the bluetooth equipment sources of sound such as mobile phone are connected to audio-frequency power amplifier by bluetooth module by sound accompaniment, power amplifier is connected to loudspeaker, each circuit of power circuit module and other is connected, electric power is provided.
Described microphone pickup device divides two-way output for gathering user people's acoustical signal, the bluetooth module of leading up to exports other bluetooth equipments such as mobile phone to, another road outputs to prime amplifier by on-off controller, and amplifying signal outputs to loudspeaker by power amplifier after by reverberation circuit handler sound effective value.
The bluetooth module Corresponding matching built-in with bluetooth equipment terminals such as mobile phones by described bluetooth earphone embedded with bluetooth module is connected.
Principle of work of the present utility model is: model the utility model bluetooth earphone is connected with the bluetooth of the Bluetooth terminals such as mobile phone, when mobile phone will enter talking state, control and make on-off controller in closed condition by the Karaoke switch, between microphone pickup device and prime amplifier, disconnect, the microphone pickup device is directly by other bluetooth equipment couplings such as bluetooth module and mobile phone, enter other bluetooth equipments such as mobile phone, do not enter audio amplifier circuit, now other bluetooth equipments such as mobile phone are in normal operating conditions.
