The utility model has the advantages that：

It can be seen that bluetooth headset provided by the utility model will by the way that a detachable audio frequency adaptor is arranged Outer sound audio signal is exported from sound mouth, the ear that air converts input human body is carried out by hollow pipeline, to reduce directly from out Impact of the audio signal of sound mouth output to human body ear, while leakage sound can be greatly reduced, make user that secret be kept to converse. When removing audio frequency adaptor, outer loud mode can be directly switch to.The random switching of two kinds of call modes, not only meeting makes In the mode requirement of different call environments while the usage experience of user can be improved in user.

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 to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it can also be obtained according to these attached drawings other attached drawings.

Fig. 1 is the schematic diagram of the utility model bluetooth headset；

Fig. 2 is the schematic diagram of earplug in Fig. 1；

Fig. 3 is the partial sectional view of Fig. 1.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work All other embodiment obtained, fall within the protection scope of the utility model.

It please refers to Fig. 1, a kind of bluetooth headset 100 provided by the utility model, including shell 10 and is torn open with the shell 10 Unload the audio frequency adaptor 20 of formula connection.One end of the shell 10 is equipped with sound mouth 11, and the other end of shell 10 is equipped with USB interface (not indicating).In present embodiment, the bluetooth headset 100 is clip-on type earphone, is designed according to root outside human body ear, the shell The shape of body 10 is roughly the same with the profile of human body ear.When wearing, the bluetooth headset 100 is hung on the rear basal part of the ear of human body, The shell 10 includes that one end of the sound mouth 11 is opposite with the ear canal of human body, and the audio of bluetooth headset 100 is conducted into The ear of human body.

Referring to figure 2., the audio frequency adaptor 20 includes interconnecting piece 21, conducting part 22 and earplug portion 23.The interconnecting piece Set 21 is set to one end that the shell 100 is equipped with the sound mouth 11, and the conducting part 23 is extended to form from the interconnecting piece 21, The earplug portion 23 is extended to form from the conducting part 22 towards close to the direction of the interconnecting piece 21, the earplug portion 23 it is interior Gap 24 is formed between wall and the outer wall of the conducting part 22.That is, the extending direction in the earplug portion 23 and the biography The extending direction for leading portion 22 is opposite.

When user wears the bluetooth headset 100, the shell 10 is hung on the rear basal part of the ear, the earplug portion 23 is directly Fill in ear.As shown in figure 3, the audio that the sound mouth 11 exports first passes through the extruding of the conducting part 22, then import again Into the ear canal of human body, leakage sound can be greatly reduced, make user that secret be kept to converse.That is, the utility model provides Audio frequency adaptor 20 conducting part 22 be a hollow pipeline, from 100 sound mouth 11 of bluetooth headset export outer resonant frequency Signal can both reduce the sound directly exported from sound mouth 11 by the ear of the air transmission conversion input human body of conducting part 22 Impact of the frequency signal to human body ear, while leakage sound can be greatly reduced, make user that secret be kept to converse.

When user does not need to keep secret call, the audio frequency adaptor 20 and the shell 10 can be divided at any time From at this point, the sound mouth 11 of the bluetooth headset 100 can allow user that can also listen to for outer loud mode not exclusively with extraneous sound insulation Surrounding enviroment, to avoid security risk.

It can be seen that bluetooth headset 100 provided by the utility model, by the way that a detachable audio frequency adaptor is arranged 20, the ear that air conversion inputs human body is carried out by hollow pipeline by outer loud audio signal is exported from sound mouth 11, to reduce Impact of the audio signal directly exported from sound mouth 11 to human body ear, while leakage sound can be greatly reduced, protect user Hold secret call.When removing audio frequency adaptor 20, outer loud mode can be directly switch to.Two kinds of the random of call mode are cut It changes, not only meets user in the mode requirement of different call environments, while the usage experience of user can be improved.

Meanwhile 20 structure of audio frequency adaptor is simple, and it is small in size, it is easy to carry, it provides convenience to user.

Specifically, 22 internal diameter of conducting part of audio frequency adaptor 20 is less than the internal diameter of the interconnecting piece 21, the earplug portion 23 The direction of outer described without leave conducting part 22 towards the interconnecting piece 21 incrementally increase.That is, the earplug portion 23 is substantially In umbrella, when user is in secret call mode, the compactness of earplug and human body ear when wearing can be increased, to have Effect reduces the interference of external noise.

The material of the audio frequency adaptor 20 is soft rubber material, and is formed by integral forming process.In present embodiment, The material of the audio frequency adaptor 20 is silica gel, and the comfort level of user's wearing can be improved in silica gel material.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
