Description
Technical field
The utility model belongs to technical field of electronic communication, and in particular to a kind of bluetooth headset.
Background technique
In the prior art, it is sometimes necessary to wear detection to bluetooth headset to realize that such as ear-phone function module is opened
The functions such as pass, and wearing detection is carried out using capacitance induction principle, this detection method of wearing needs to increase the electricity worn and detected
Pole (such as copper foil or steel disc) causes earphone volume big, at high cost and increase structure design difficulty.
Utility model content
The utility model provides a kind of bluetooth headset, and structure is complicated, body when for solving existing bluetooth headset wearing detection
The big and at high cost problem of product reduces earphone cost input, reduces earphone body while realizing that bluetooth headset wears detection
Product, easy to carry and placement, promotes user experience.
In order to solve the above-mentioned technical problem, the following technical solutions are proposed is resolved for the utility model institute:
A kind of bluetooth headset, including loudspeaker and Bluetooth chip, which is characterized in that further include induction electrode and and Bluetooth chip
The capacitance detecting chips of communication connection；The induction electrode is pole piece in the loudspeaker；The pole piece by connecting line or
Arrangements of electric connection is connected with the capacitance detecting chips.
Further, the capacitance detecting chips are Cypress CapSense controller.
Further, the model CY8C4014 of the capacitance detecting chips.
Further, the dielectric material of high dielectric constant is provided in the side of the close user's ear of the pole piece.
Further, arrangements of electric connection is probe adapter or elastic slice
Compared with prior art, the advantages of the utility model and beneficial effect is: pole piece is as induction in multiplexing loudspeaker
In addition electrode does not individually add induction electrode, realize that earphone wears detection close to sensing principle using capacitor, reduce knot in earphone
Structure design complexities, input cost is low, and small in size, easy to carry and placement.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be practical to this
New embodiment or attached drawing needed to be used in the description of the prior art are made one and are briefly introduced, it should be apparent that, it is described below
Attached drawing is some embodiments of the utility model, for those of ordinary skill in the art, is not being made the creative labor
Under the premise of, it can also be obtained according to these attached drawings other accompanying drawings.
Fig. 1 is a kind of functional block diagram of embodiment of the utility model bluetooth headset.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
When carrying out wearing detection to earphone, in order to avoid additional induction electrode, as shown in Figure 1, the present embodiment relates to
And a kind of bluetooth headset, including loudspeaker 10, Bluetooth chip 20, induction electrode and the capacitance detecting communicated to connect with Bluetooth chip 20
Chip 30；Induction electrode is pole piece 40 in loudspeaker 10, and when bluetooth headset is worn to user's ear, pole piece 40 is close to user
Ear；Pole piece 40 is connected by connecting line or arrangements of electric connection with capacitance detecting chips 30.In the present embodiment, induction electrode
It can also be other metalworks in loudspeaker metal shell or loudspeaker, pole piece 40 passes through probe adapter 60 and capacitance detecting core
Piece 40 is connected.Alternatively, pole piece 40 can be connected by elastic slice or other interconnection means equal to capacitance detecting chips 30.
Specifically, bluetooth headset is to wear bluetooth headset in the present embodiment, and ear-speakers are commonly designed close to human ear
Position, it is nearest apart from human ear, based on capacitor close to sensing principle, user's ear wear earphone when, human ear protrusion can and
The pole piece 40 of loudspeaker is close, changes pole piece 40 to dielectric constant greatly, so that the capacitance of 40 pairs of the earth of pole piece
Change, capacitance detecting chips 30 are electrically connected by probe with pole piece 40, and 40 direct-to-ground capacitance value of pole piece is detected.The present embodiment
In, capacitance detecting chips 30 use Cypress CapSense controller, such as the chip or other classes of model CY8C4014
The detection chip of the type PIC12LF1552T chip that perhaps capacitance detecting chips 30 are Microchip is TI's
MSP430FR2512/MSP430FR2522 chip etc..It can be for detection predetermined capacitive threshold value be worn, so that in capacitance detecting
When the capacitor that chip 30 detects reaches the threshold value, judge to be in wearing state still non-wearing state when current earphone, according to
The control to earphone may be implemented in itself or the judging result is sent to indigo plant for the state of current earphone, capacitance detecting chips 30
Tooth chip 20 realizes the control to earphone, for example, part functional module enters low-power consumption mode, headset switch machine or right in earphone
Earpiece volume size adjustment etc..
In the present embodiment, the dielectric material of high dielectric constant can be provided with close to the side of user's ear in pole piece 40
Material, such as sound-absorbing foam or rubber etc..Preferably, sound-absorbing foam is filled, advantage is: (1) from acoustical behavior: inside foam
Numerous micropore in a disguised form increases the volume of the operatic tunes after loudspeaker, greatly reduces headphones sound distortion, improves headphone acoustic experience,
And then improve earphone bass audio；(2) sound-absorbing foam and the common charged media of air, improve dielectric constant.
In order to improve the accuracy and sensitivity that earphone wears detection, adjusted by software (such as adjustment predetermined capacitive threshold value)
Whole suitable sensitivity effectively avoids false triggering for distinguishing whether earphone is normally worn.In addition, certain small size loudspeaker
Pole piece 40 can have that sensitivity is less than normal, cause the signal-to-noise ratio of response to increase, cause the probability of false triggering to increase, at this time
Sensitivity compensation can be realized by reducing distance between loudspeaker and human ear.
The present embodiment bluetooth headset is multiplexed pole piece 40 in loudspeaker, does not individually in addition add induction electrode, is connect using capacitor
Nearly sensing principle realizes that earphone wears detection, reduces complex structural designs degree in earphone, input cost is low, and small in size, is convenient for
It carries and places.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that:
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
