Abstract
Provided is a noise-reduction Bluetooth headset, comprising a signal microphone, an operation processing module, a Hi-Fi speaker, a data storage module, and a volume adjustment module. The invention provides a noise-reduction Bluetooth headset of which the degree of intelligence is improved, and the noise reduction and volume adjustment functions bring better experience to users.
Description
Technical field
The present invention relates to ear speaker device, especially with regard to a kind of can the bluetooth ear of noise reduction
Machine.
Background technology
Nineteen ninety-five, Ericsson proposes bluetooth concept at first.Bluetooth specification uses
Microwave frequency band works, transfer rate 1M per second byte, maximum transmission distance 10 meters,
Can reach 100 meters by increasing transmitting power.Bluetooth technology is global open,
Having good compatibility in the world, the whole world can be by low cost
Invisible bluetooth network is connected.Bluetooth technology is applied at hand-free by bluetooth earphone exactly
A kind of earphone on earphone.
Existing bluetooth earphone, only achieves and allows user can exempt irritating electric wire
Impede, the most easily accept the function of audio-frequency information or call comfortablely.
At present, although have can the earphone of noise reduction, but still compare in intelligence degree
Low shallow, such as noise reduction and volume adjusting bring the experience of user, thus there is fall
Make an uproar and be combined the demand closer to user with volume adjusting.
Summary of the invention
In view of this, the present invention solves above-mentioned technical problem, it is provided that one can drop
The bluetooth earphone made an uproar.
The purpose of the present invention is achieved through the following technical solutions:
A kind of can the bluetooth earphone of noise reduction, including signal mike, calculation process mould
Block, Hi-Fi loudspeaker, data memory module, volume adjusting module.
Specifically, described signal mike is used for detecting ambient noise, described news
Number mike is connected with described calculation process module and will the noise signal transmission of detecting
To described calculation process module, described calculation process module is in order to divide noise signal
Analysis processes and generates the identical de-noising signal of opposite in phase amplitude and passed by this de-noising signal
Passing described Hi-Fi loudspeaker, described Hi-Fi loudspeaker send and shake with noise opposite in phase
Identical noise reduction sound wave, meanwhile, user is adjusted by volume adjusting module
Save this kind and the volume of bluetooth earphone of noise reduction can obtain suitable volume, described data
Memory module, described volume adjusting module are connected two-by-two with described calculation process module,
Described data memory module records ambient noise intensity and user regulation obtains
Volume, when identical noise intensity occurs again time, described calculation process module
Match the record of described data memory module and control described volume adjusting module and enter
The volume adjusting that row adapts.
The present invention provides the benefit that compared to prior art:
The present invention provide a kind of can the bluetooth earphone of noise reduction, it is achieved intelligence degree carries
Rising, particularly noise reduction and volume adjusting brings the experience that user is more excellent.
Accompanying drawing explanation
The invention will be further described to utilize accompanying drawing, but the embodiment in accompanying drawing is not
Constitute any limitation of the invention.
Fig. 1 is the control structure principle of a kind of bluetooth earphone counting step of the present invention
Figure.
Detailed description of the invention
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and reality
Execute example the present invention is described in further detail.
Refer to Fig. 1, the embodiment of the present invention includes:
A kind of can the bluetooth earphone of noise reduction, including signal mike 1, calculation process
Module 2, Hi-Fi loudspeaker 3, data memory module 4, volume adjusting module 5.
Specifically, described signal mike 1 is used for detecting ambient noise, described
Signal mike 1 is connected with described calculation process module 2 and by the noise letter of detecting
Number passing to described calculation process module 2, described calculation process module 2 is in order to right
Noise signal analyzing and processing generates the identical de-noising signal of opposite in phase amplitude should
De-noising signal passes to described Hi-Fi loudspeaker 3, described Hi-Fi loudspeaker 3 send with
The noise reduction sound wave that noise opposite in phase amplitude is identical, meanwhile, user passes through
Volume adjusting module 5 regulates this kind and can the volume of bluetooth earphone of noise reduction obtain properly
Volume, described data memory module 4, described volume adjusting module 5 are with described
Calculation process module 3 is connected two-by-two, and described data memory module 4 records the external world
Noise intensity and user regulate the volume obtained, when identical noise intensity again
When generation, described calculation process module 2 matches described data memory module 4
Record and control the volume adjusting that described volume adjusting module 5 carries out adapting.
It is obvious to a person skilled in the art that the invention is not restricted to above-mentioned demonstration
The details of property embodiment, and in the spirit or essential attributes without departing substantially from the present invention
In the case of, it is possible to realize the present invention in other specific forms.Therefore, no matter from
From the point of view of which point, embodiment all should be regarded as exemplary, and be unrestricted
Property, the scope of the present invention is limited by claims rather than described above,
It is intended that it is all by fall in the implication of equivalency and scope of claim
Change is included in the present invention.Any reference in claim should not regarded
For the claim involved by restriction.
Moreover, it will be appreciated that although this specification is been described by according to embodiment,
But the most each embodiment only comprises an independent technical scheme, description
This narrating mode is only that for clarity sake those skilled in the art should will say
Bright book is as an entirety, and the technical scheme in each embodiment can also be through suitable group
Close, form other embodiments that it will be appreciated by those skilled in the art that.
