Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
A kind of high-fidelity bluetooth earphone, as shown in Figures 1 to 5, including the head beam 1 in u-shaped structure and head beam 1 two ends
The headset body of setting, the headset body at two ends can export respectively as the L channel of audio frequency and R channel；Described headset is originally
Body includes earmuff body 2, and described earmuff body 2 includes face-piece 3 and the functional unit of face-piece 3 inner side；Described functional unit includes:
Bluetooth module, including main control chip, is used for accepting Bluetooth signal, and it is converted into electric signal output, in master control
Antenna for transmitting and receiving electromagnetic wave energy is connected with chip；
And horn module, it is connected with described bluetooth module, convert electrical signals to acoustical signal output, this horn module
Including several vibration units 4；The both sides of described horn module form the front operatic tunes 5 and the rear operatic tunes 6 respectively；Described face-piece 3 sets
There is the pore making the described rear operatic tunes 6 and extraneous conducting；
And power amplifier module, it is connected with described bluetooth module and horn module, amplify the audio signal that Bluetooth chip sends
Power, provides more high-power audio signal for loudspeaker；Power amplifier module (i.e. power amplifying system) can select amp
Max97220 series module.
And power module, it is connected with described bluetooth module, horn module and power amplifier module, be that three powers.
This earphone can easily pass through bluetooth module with corresponding bluetooth equipment (as mobile phone, panel computer, notebook
Deng) support the use, receive Bluetooth signal, carry out the transmission of audio frequency.
Above-mentioned face-piece 3 side inwardly is provided with sponge leather sheath earmuff 7 around the described front operatic tunes 5, and the front operatic tunes of earphone is exactly
Cavity and human ear between for the vibration unit (loudspeaker), around has sponge leather sheath to surround and sound insulation；Earphone back cavity is exactly vibration unit
(loudspeaker) cavity and earphone outer covering between.When earphone pronunciation works, the diaphragm in vibration unit is vibrating back and forth, generation
Air-flow forms pressure between the front operatic tunes and the rear operatic tunes, and because earphone is worn over head, the airflow portion of the front operatic tunes will be by sponge
Absorb, the air-flow of the rear operatic tunes is discharged by the pore on face-piece, and according to resonance principle, the front operatic tunes is suitable with rear operatic tunes capacity, loudspeaker
Diaphragm reaches maximum resonance it is ensured that the output of high-fidelity tonequality.
The effect of pore mainly has two, first, being to lose heart during the vibration for horn diaphragm, is unlikely in big pressure condition
Under cause the deformation of horn diaphragm；In addition, its effect is reasonably to adjust capacity, ante-chamber and the air-flow of back cavity is allowed to make a concerted effort to be formed
Resonance, increases the bass effect of earphone.
Above-mentioned main control chip adopts ws9623 family chip.Because common Bluetooth chip audio signal power out only has
About 10mw, so the power amplifier chip from a 130mw；After middle bass reinforcement, it is easily caused the muddy of bass
Turbid or even thunder, make experiencer's sensation irritated, in an optional embodiment, a dsp (number can be connected on main control chip
Word signal processing unit), using dsp technology to 300-500hz about frequency range suppress, thus allow hearer to have preferably listening
Feel experience.

The earphone knob 9 of mesh switching.Specifically, can be on the earmuff body of both sides, one of earmuff body arranges the rotation of volume adjusting
Button, the knob of another setting song switching, enormously simplify operation, convenient use person appreciates music, brings good use
Experience.
Above-mentioned vibration unit includes 10,1 30mm moving-coil unit 11 of 1 50mm moving-coil unit and 30mm moving-coil unit
4 peripherally disposed 20mm moving-coil units 12 of outside.Above-mentioned 20mm moving-coil unit 12 is along described 30mm moving-coil unit 11
Circumferencial direction be uniformly arranged.The operatic tunes 6 after this bluetooth earphone band independence, it is ensured that the clear sound of voice unit, is not subject to bass list
The reflection sound wave interference of unit.Multiple independent moving-coil units can ensure that the good output of tonequality.
In an optional embodiment, it is provided with audio frequency line jack 13 in the bottom of above-mentioned earmuff body 2.During use, pass through
Tone frequency channel wire connects audio frequency line jack 13 and the playback equipments such as Mp 3 player, carries out music, earmuff body 2 is worn on ear,
Head beam 1 plays the effect being fixed on head that consolidates earphone, and earphone passes through sound horn.
User can individually adjust volume and switching song, the tune of one of which function by the knob on control panel
Section will not produce related impact to another function, meets the demand that user regulates and controls for music, through the tonequality energy optimizing
Bring the stimulation on sense organ to hearer, experience gratification on the spot in person and be subject to.
This utility model forms the front operatic tunes 5 and the rear operatic tunes 6 respectively in the both sides of loudspeaker, face-piece 3 be provided with make the rear operatic tunes with
The pore of extraneous conducting, by the discharge to excessive gas in earphone for the pore on cavity body structure, makes the air pressure within earphone reach
To balance it is ensured that earphone exports tonequality.This earphone can easily pass through bluetooth module with corresponding bluetooth equipment (as handss
Machine, panel computer, notebook etc.) support the use, receive Bluetooth signal, carry out the transmission of audio frequency.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in this utility model
Protection domain within.
