But this series products can only use as audio amplifier, when there being phone, must audio amplifier be pulled up, just can normal ON phone, to the inconvenience of user still with serving in use.
Utility model content
In order to overcome the problems referred to above, the utility model provides a kind of audio amplifier of can working as in usual situation to use to society, need not pull up audio amplifier, just can work as the mobile telephone external voice device that headset uses when there being phone.
The technical solution of the utility model is: provide a kind of mobile telephone external voice device, comprise shell, in described shell, be provided with audio frequency power amplifier pcb board, battery, loudspeaker and microphone successively from bottom to up, described loudspeaker and microphone are connected with the circuit on described audio frequency power amplifier pcb board respectively; The lower surface of described shell is provided with 3.5 audio jack, and described 3.5 audio jack are connected with the circuit on described audio frequency power amplifier pcb board.
As to improvement of the present utility model, the lower surface of described shell is also provided with rotating mechanism, described 3.5 audio jack and described rotating mechanism pivot joint.
As to improvement of the present utility model, described shell is plastic casing.
As to improvement of the present utility model, also comprise plug cover, in plug cover, be provided with the incorporating section of receiving described 3.5 audio jack.
As to improvement of the present utility model, outside the bottom surface of described plug cover, be provided with cleaning cloth.
As to improvement of the present utility model, described cleaning cloth is superfine fibre cloth.
As to improvement of the present utility model, described battery is rechargeable lithium battary.
The utility model is compared with the direct insertion little audio amplifier of existing mobile phone, and the utility model has been provided with microphone, and overcoming existing product can only listen song, the problem that can not converse, and when phone comes, need not pull up audio amplifier and just can directly receive calls; This product is channel structure, not only can play music, sound of can also recording, and realizes call.
In addition, this product also tool have the following advantages:
Compared with mobile phone communication, the utility model, owing to being mobile telephone external voice call, can reduce the harm of electromagnetic radiation to human brain; Mobile phone self has loudspeaker and microphone, but position not in think, play and recording clear not; This product is face people due to the position of loudspeaker and wheat, and shortens and the distance of people, and volume and effect are all better than loudspeaker machine and the microphone of mobile phone, and sound is larger, more clear.
Be different from traditional wired audio amplifier, eliminate tone frequency channel wire, there is no the constraint of earphone cord, directly insert and can play and record, convenient, without the need to wearing, liberation ears are more comfortable; And individual small and exquisite fashion, more portable;
Be different from traditional Baffle Box of Bluetooth, cancelling signal pairing connection procedure, directly inserts and connects, more convenient.
