Description

A kind of wireless headset
Technical field
This utility model is related to ear phone technology field, more particularly to a kind of wireless headset.
Background technology
In-Ear wireless headset in the market, particularly TWS earphone, major defect has following aspects:
1st, the earphone tonequality aspect low-frequency effect of same type is very poor in the market, is primarily due to space problem, simultaneously Horn single body very little, loudspeaker low-frequency effect is maximum to play effect to meet not to have enough spaces after loudspeaker;
2nd, because being In-Ear requirement, volume can not be too big, and the earphone of same type is in design stacking in the market During, space availability ratio is not high, and because the stack manner of battery is unreasonable, the volume of battery diminishes, and battery capacity is not high, and one As using two to three hours;
3rd, wear comfort is bad, and volume is generally bigger than normal, and rise after wearing ear, and comfort level is very poor, and wear time is longer just Ear distending pain can be felt, feel bad;The earphone wear comfort of same type is bad in the market, and main cause is two factors, Headset main body is done the big degree feeling distending pain to human ear to meet the volume requirement of battery by the first, its two be earplug angle Degree not do by the physiological structure of human ear lead to user after wearing ear mouth to the area between human ear tragus and external acoustic pore Domain is subject to very big top power, has the discomfort such as pain after its result wear time is long, lead to second of this design Problem is that the area coverage to earhole of speaking of earplug front end reduces, and tonequality impression can be deteriorated.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, this utility model provides a kind of wireless headset, and it is by speaker sound Chamber design near the side of speaker, forms an independent rear operatic tunes, is that speaker is provided behind enough skies in body shell Between require, so as to maximum play effect, in the case of not increasing volume, to improve ear further meeting the low frequency behavior of speaker The low-frequency effect of machine and the degree of balance ensureing left and right acoustic channels sound.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of wireless headset, including body shell, is fixed on battery in body shell, PCBA board and wireless transceiver, has The pleasant earplug of speaker;Described PCBA board is connected with described battery, wireless transceiver and speaker respectively;In described body shell It is additionally provided with the rear operatic tunes near described speaker.
Further, the described rear operatic tunes include being arranged on the side near described speaker for the described body shell operatic tunes body and For sealing the operatic tunes lid of this operatic tunes body.
Further, described battery is cylinder type lithium battery;Described cylinder type lithium battery axis and the folder of PCBA board plane Angle is 0~90 °.
Further, described cylinder type lithium battery axis and the angle of PCBA board plane are 0 °.
Further, also include at least one charging needle, its perpendicular to described PCBA board plane and fixation be connected electrically in described In PCBA board;At least one charging hole corresponding with described at least one charging needle is provided with described body shell, described charging needle is worn Overcharge hole extends to outside described body shell.
Further, described at least one charging needle is 3 charging needles side by side.
Further, also include the antenna button lid that is arranged in described PCBA board, the antenna of described wireless transceiver sets Put on described antenna button lid.
Further, described antenna button lid is provided with antenna contacts, described PCBA board is provided with can with described The antenna shrapnel of the corresponding contact of antenna contacts.
Further, earflap and soft rubber sleeve are also included, described soft rubber sleeve is matched with described body shell profile, to be sleeved on In described body shell.After wearing, described soft rubber sleeve or body shell rely on the tragus of ear and antitraguss to fix, and described earflap corresponds to Lean against on the antihelix of ear.
Further, described earplug axis perpendicular to the angle between the B plane that Y plane is constituted and X-plane For a angle, its angle is 145+/- 3 °;The described earplug axis A that constituted of plane being located perpendicular to described PCBA board puts down Angle between face 25 and Z plane is β angle, and its angle is 110+/- 3 °.
This utility model has the advantages that:
(1) this wireless headset, by the side of speaker operatic tunes design close speaker in body shell, forms one independent The operatic tunes afterwards, is that speaker is provided behind enough spaces and requires come the low frequency behavior to meet speaker so as to maximum play effect, Improve the low-frequency effect of earphone and the degree of balance ensureing left and right acoustic channels sound further in the case of not increasing volume;Solve The problem of existing same type wireless headset poor effect in low frequency tonequality;
(2) this wireless headset adopts cylinder type lithium battery, and does optimization processing to its disposing way, it is preferred that cylindrical Lithium battery axis is parallel to each other with PCBA board plane, maximally utilises earphone on the premise of can meeting wear comfort The space of body shell, the maximum capacity of battery can reach the use time of three to four hours;Simultaneously by wireless headset Total height be reduced to below 18mm, realize miniaturization further;This kind of optimization design, the solder joint on battery protecting plate and PCBA Solder joint on plate is spaced from each other, the possibility being not in contact with, and can be prevented effectively from PCBA board solder joint and battery when producing welding Protection board solder joint contacts and short circuit, and then leads to the problem of disabler;
(3) the charging design of existing wireless headset is all using one piece of detached PCBA, makees contact point and expose on PCBA Outside ear casing, then contact to realize charging by probe on external power supply, but charging contact has welding asks Topic leads to the bad problem of product function, or even the problem that cannot charge, and increases production cost;And this wireless headset is to charge Pin is directly weldingly fixed on PCBA, and when assembling, charging needle passes through the charging hole in body shell, extends to body shell Outer surface, then realizes charge requirement by contacting with the probe of external charger.The implementation method of charging copper pin, is easy to Produce, remove bonding wire operation from, effectively reduce and lead to the bad problem of product function because of bonding wire, reduce production station and improve simultaneously Production efficiency, reduces product cost;
(4) this wireless headset comfortable wearing, difficult for drop-off, after being worn on user ear, the Poly cap on earplug is very Effectively agree with ear external acoustic pore periphery well, prevent the problem that the low frequency of sound leaks well;Earplug is according to the life of human ear Reason structure has done the structure adjusting to meet human ear of two angles, the very big raising of wear comfort, this structure simultaneously to it By going out acoustic aperture, maximum is accomplished to the area coverage of earhole, so that headphones sound transmission is more unimpeded, more preferably, product are comfortable for tonequality impression The more existing similar-type products of property are outstanding.
