Background technology
Bone conduction is a kind of sound conduction mode, is different from gas conduction pattern, carries out sound by earplug, air
The conduction of sound, but by sound being converted into the mechanical vibration of different frequency, by the skull of people, bone fan
Road, the transmission of internal ear lymph fluid, spiral organ of Corti, acoustic nerve, auditory center transmit sound wave.With respect to shaking
Film produces the classical sound conduction mode of sound wave, and bone conduction eliminates the step of many sound wave transmission, can be noisy
Miscellaneous environment realizes sound-reducing clearly, and sound wave also will not have influence on because of spreading in atmosphere
Other people.
But the LF-response of bone conduction earphone is poor, it would be highly desirable to need a kind of technical scheme to solve low-frequency sound
Conducting problem.
Utility model content
The purpose of this utility model is to provide a kind of wear-type bone conduction earphone, and this earphone is used for being worn on ear
Outward, this earphone has the effect improving LF-response.
In order to solve the problems referred to above, the technical solution adopted in the utility model is:
A kind of wear-type bone conduction earphone, including U-shaped support and two earphones, the two ends of described support and institute
State two earphones to be connected, described earphone be provided with bone-conduction speaker, it is characterised in that: described bone conduction
Speaker includes upper shell, lower seat, support column, rectangular slab piezoelectricity a period of time, support beam, vibration column, vibration
Film, wherein, described upper shell and described lower seat mutually support connection, and described rectangular slab piezoelectricity a period of time passes through institute
Stating support beam to be connected with described vibration column, described support column is positioned at the underface in described rectangular slab piezoelectricity a period of time,
The surface of described lower seat, described vibrating diaphragm is positioned at described vibration column and is overlying on described upper shell.
Through the experiment of the applicant, matrix plate piezoelectricity a period of time is for the response best results of low frequency and right
For high-frequency signal, due to the mechanism of bone conduction, generally also there is higher laser propagation effect, therefore overall
The sound signal quality that upper earphone obtains is optimal.
As improving further, described U-shaped support is the wearable circular arc type bracing frame at head or cervical region.
As improving further, this bone-conduction speaker includes upper shell, lower seat, support column, rectangular slab pressure
Electricity a period of time, support beam, vibration column, vibrating diaphragm.
As improving further, this rectangular slab piezoelectricity a period of time uses intermediate line supporting way.
As improving further, the piezoelectric constant of the piezoceramic material in rectangular slab piezoelectricity a period of time is more than
250×10-12m/v。
As improving further, upper shell, lower seat, vibrating diaphragm are coated with silica gel material.
The beneficial effects of the utility model:
This utility model wear-type bone conduction earphone can be worn on head by user, earphone laminating ear
At anterior cheekbone, receiving sound by the bone-conduction speaker in earphone, the sound quality obtained is preferable.

Detailed description of the invention
Below with reference to the accompanying drawings embodiment of the present utility model is described.At an accompanying drawing of the present utility model or
Plant the element described in embodiment and feature can be shown in one or more other accompanying drawings or embodiment
The element and the feature that go out combine.It should be noted that, for purposes of clarity, accompanying drawing and explanation eliminate with
This utility model unrelated, parts known to persons of ordinary skill in the art or the expression of process and description.
Below in conjunction with the accompanying drawings this utility model is described further.
As it is shown in figure 1, a kind of wear-type bone conduction earphone including U-shaped support and earphone, in described earphone
Being provided with bone-conduction speaker, this bone-conduction speaker includes upper shell 1, lower seat 2, support column 3, square
Shape plate piezoelectricity a period of time 4, support beam 5, vibration column 6, vibrating diaphragm 7.Wherein, upper shell 1 and lower seat 2 phase
Supporting connection mutually, rectangular slab piezoelectricity a period of time 4 is connected with vibration column 6 by support beam 5, and support column 3 is positioned at
The underface in rectangular slab piezoelectricity a period of time 4, the surface of lower seat 2, vibrating diaphragm 7 is positioned at vibration column 6 and is overlying on
On upper shell 1, rectangular slab piezoelectricity a period of time 4 drives vibration column 6 to pump by deformation, so that
Sound conduction is in the internal ear of people.
This utility model selects rectangular slab piezoelectricity a period of time, through the experiment of the applicant, matrix plate piezoelectricity a period of time
For the response best results of low frequency, and for high-frequency signal, due to the mechanism of bone conduction, generally
Also having higher laser propagation effect, the sound signal quality of the many acquisitions of earphone is optimal the most on the whole.
As improving further, this rectangular slab piezoelectricity a period of time uses intermediate line supporting way, namely support column 3
It is positioned at the underface in rectangular slab piezoelectricity a period of time 4.By this intermediate supports mode, reduce low frequency pressure further
The one class resonant frequency in electricity a period of time, increases the amplitude in piezoelectricity a period of time, solves low frequency sound signals reproduction and does not fills
The problem divided.
