Abstract

The utility model pertains to a Bluetooth headset, comprising a main frame, two ear splitters extending out from two sides of the main frame, and earplugs positioned on the free end of the ear splitters. The earplug is internally provided with an althorn and a sackbut. All the althorn and the sackbut are connected with the main frame by a signal wire. By arranging an althorn and a sackbut in the same earplug of the headset, the utility model applies the principles of different sound boxes (speakers) in a HiFi stereo to the Bluetooth headset and breaks the limits of general wireless earphones. In the utility model, the althorn and the sackbut are sensitive to audio signals with different frequency bands, that is, high and intermediate frequency audio signals are played by the althorn while the intermediate and low frequency audio signals are played by the sackbut, thus signal of high, intermediate and low frequency bands are all well reproduced when played, and a surround stereo effect and a better sound effect can be achieved.

Description

The blue teeth wireless earphone

Technical field

The utility model relates to the earphone technical field, relates in particular to a kind of blue teeth wireless earphone.

Background technology

At present, the blue teeth wireless earphone uses more and more widely, not only be used for cooperating and receive calls with communication terminals such as mobile phones, also be used for gradually answering music with various audio and video display devices, listening to program of radio station etc., yet, all only be provided with loudspeaker in each earplug of existing blue teeth wireless earphone, because the limitation of loudspeaker self-characteristic, make that its sound to a certain frequency range is comparatively responsive, audio signal in this frequency range can be reproduced well, but the reproduction effect of the audio signal of other step sections is not good enough.

The utility model content

Technical problem to be solved in the utility model is: a kind of blue teeth wireless earphone is provided, and it can provide preferable audio.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of blue teeth wireless earphone, comprise that main frame, two ears that extend out respectively from the both sides of main frame split and be arranged at corresponding ear and split free-ended earplug, be provided with a loudspeaker and a bass horn in the described earplug, described loudspeaker and bass horn all link to each other with described main frame by holding wire.

Described ear is split the cable hole that passes for holding wire that inside is provided with perforation.

The free end that each ear is split is curved around forming ear-hang.

The beneficial effects of the utility model are: by a loudspeaker and a bass horn are set in the same earplug of earphone, the principle of the different audio amplifiers of HiFi combined acoustics (loudspeaker) is applied in the blue teeth wireless earphone, break through the limitation of general wireless headset, loudspeaker, bass horn are respectively to the audio signal sensitivity of different frequency range, high intermediate-freuqncy signal is play by loudspeaker, and the medium and low frequency signal is play by bass horn, thereby make the signal of high, medium and low frequency all can obtain play reproduction well, have the surround sound effect, the earphone audio is better.

Fig. 3 is the earplug internal structure schematic diagram of the utility model blue teeth wireless earphone.

Fig. 4 is the result of use detection figure of the utility model blue teeth wireless earphone.

Below in conjunction with accompanying drawing the utility model is described further.

Embodiment

As shown in Figures 1 and 2, the utility model provides a kind of blue teeth wireless earphone, comprises that main frame 1, two ears that extend out respectively from the both sides of main frame 1 split 2 and be arranged at corresponding ear and split 2 free-ended earplugs 3.

Wherein, described main frame comprises shell, is located at pcb board and power supply in the shell.

Ear is split 2 and is used to connect main frame and earplug, and provides a supporting role.Ear is split 2 and is extended to form respectively from the both sides of the shell of main frame, and ear is split the cable hole (scheming not shown) that 2 inside have perforation.Each ear is split 2 free end and also can further be bent around forming ear-hang 22, so that in use, can collude easily and is hung on the ear.

And being provided with a loudspeaker 30 and a bass horn 32 in the described earplug 3, described loudspeaker 30 and bass horn 32 all link to each other with the pcb board of described main frame by holding wire.And holding wire can split 2 cable hole from ear and pass and be connected to main frame 1, thereby makes the earphone outside can't see holding wire, thereby has clean and tidy overall appearance.

By a loudspeaker 30 and a bass horn 32 are set in the same earplug 3 of earphone, and the audio settings difference of the interior different loudspeaker of same earplug, the sound that the speaker sound of performance high pitch will show bass horn is little, this setting meets the receiving sensitivity reaction of human body to different range sound, causes desirable sound effect thereby reach.The ear of human body is in the acceptable sound, and the high pitch of healing more receives responsive, and in brief, high pitch is equally big with bass part sound partly, and high pitch can be covered bass, so this setting is to show different audio frequency simultaneously.As shown in Figure 4, ordinate is represented volume and sensitivity among the figure, its numerical value is bigger, sound is bigger, sensitivity is also big more, and abscissa is represented the audio frequency height, promptly is to high pitch audio frequency (20KHz) by audio bass (20Hz), curve A among the figure is represented the response curve of bass horn 32, and curve B is represented the response curve of loudspeaker 30.From the tendency of two curves as can be seen, loudspeaker 30, bass horn 32 are respectively to the audio signal sensitivity of different frequency range, high intermediate-freuqncy signal is play by loudspeaker 30, and the medium and low frequency signal is play by bass horn 32, thereby can make the signal of high, medium and low frequency all can obtain play reproduction well, have the surround sound effect, the earphone audio is better.

Claims

1, a kind of blue teeth wireless earphone, comprise that main frame, two ears that extend out respectively from the both sides of main frame split and be arranged at corresponding ear and split free-ended earplug, it is characterized in that: be provided with a loudspeaker and a bass horn in the described earplug, described loudspeaker and bass horn all link to each other with described main frame by holding wire.

2, blue teeth wireless earphone as claimed in claim 1 is characterized in that: described ear is split the cable hole that passes for holding wire that inside is provided with perforation.
