Description
Technical field
This utility model relates to audio-frequence player device correlative technology field, and being specifically related to a kind of full Wireless can independent assortment
Bluetooth earphone audio amplifier.
Background technology
Existing bluetooth earphone or audio amplifier include mono headset/audio amplifier and stereophone/audio amplifier, monophonic ear
Machine/audio amplifier has a Bluetooth transmission/reception unit, a phonation unit and a sound collection unit, and above unit is all pacified
It is contained in same shell, and is rendered as an entirety.Stereophone/audio amplifier, has a Bluetooth transmission/reception unit,
Two phonation units and a sound collection unit, it generally uses following two connection mode: 1, Bluetooth transmission/reception is single
Unit, L channel phonation unit, sound collection unit is all arranged in same shell, and is rendered as an entirety (left earphone/sound
Case), R channel phonation unit is arranged in a shell, and is rendered as an entirety (right earphone/audio amplifier), left earphone/audio amplifier
It is connected with being set up by cable between right earphone/audio amplifier；2, Bluetooth transmission/reception unit and sound collection unit are arranged on one
In shell, and being rendered as an entirety (main frame), left/right sound channel phonation unit is separately mounted in a shell, and respectively in
It is now an entirety (left earphone/audio amplifier and right earphone/audio amplifier), between main frame and left earphone/audio amplifier and right earphone/audio amplifier respectively
Set up by a cable and connect.Mobile phone passes through HSP/HFP, and audio frequency and control signal are encoded and pack by A2DP, AVRCP agreement
After, by Bluetooth transmission out.The transmitter/receiver unit of earphone or audio amplifier receives audio signal, passes through wired connection after decoding
It is transferred to phonation unit.Mono headset/audio amplifier is transferred to phonation unit after being mixed by left and right acoustic channels.Stereophone/audio amplifier
Left and right acoustic channels is respectively transmitted to left and right phonation unit.
But above-mentioned existing bluetooth earphone or the product form of audio amplifier and connected mode, be the user that each self adaptation is different
Using scene, it is respectively provided with following defect:
A, single sound channel bluetooth headset, be commonly available to the application such as commercial affairs/driving, is mainly used in call, because only supporting list
Sound channel, the experience listening music is poor.B, I tech clip S, be commonly available to outdoor walkman music and moving scene, main
The happy call of audition to be used for.But at every moment could listen song with earphone in indoor, show slightly inconvenience.C, the left ear of earphone, right
Must be connected by cable between ear and main frame, when motion, cable can be formed stethoscope effect with clothes friction, cause and listen
The experience of song declines.Monophonic Baffle Box of Bluetooth, is commonly available to outdoor portable and listens song to put outward, and such as square dance, rides.But sound
Quality cannot be compared with stereophone or audio amplifier.D. stereosonic blue tooth audio amplifier, is commonly available to the wireless music such as parlor and plays.
Because two phonation units, heavier, power consumption is the highest, and portability declines.Because needing for wired between the phonation unit of left and right
Cable, it is impossible to really exempt from line.E. not having a product can cover above-mentioned different application scenarios, user needs to buy different bluetooths
Product, the paying of repetition perfectly could be experienced under different scenes.
In view of this, special proposition this utility model.
