Hereinafter, a bone conduction earplug according to the present invention will be described with reference to the accompanying drawings.

1 to 5, a bone conduction earplug according to the present invention includes a main body 10 to be largely worn on the head, a bone conduction unit 20 for allowing the wearer to hear sound source data, and a drive unit 30 ).

1 and 2, the main body 10 includes two side widening portions 11 and 12 covering the wearer's ears and a connecting portion 13 between the two side widening portions 11 and 12, .

The body 10 is the same as a general earplug, and its shape and material are not limited. However, the supporting part having a predetermined elastic force is incorporated in the connecting part 13 so that the both side parts 11, So that it can be worn on the ear.

 At this time, the connection portion 13 may be worn on the back of the user (or on the back of the user) or on the user's upper edge.

1 (B), the two side widening parts 11 and 12 are unfolded on the basis of the connecting part 13 for convenience of understanding. However, the connecting part 13 may be formed as a double- It is needless to say that it is possible to borrow all kinds of known earplug type structures such as a structure in which the side windings 11 and 12 can be folded and folded and stored.

The bone conduction unit 20 is provided so as to be exposed to the inside of the warming portions 11 and 12 to vibrate the skull around the wearer's ear,

Although the figure shows an embodiment in which the bone conduction unit 20 protrudes inside the hair resting portions 11 and 12, the hair rising portions 11 and 12 are provided in a non-protruding shape according to the area, It is also possible.

The bone conduction unit 20, as shown in Fig. 3,

A housing 21 coupled to the inside (more precisely, the first and second hard cases 14 and 15) of the warming portions 11 and 12,

A vibration coil 22 built in the housing 21 to receive an acoustic signal,

A magnetic body 23 responsive to an electromagnetic field generated by an acoustic signal transmitted to the vibration coil 22,

A diaphragm 24 coupled to the magnetic body 23 to contact the skull,

A diaphragm 25 provided in the housing 21 for vibrating the diaphragm 24 in response to the magnetic body 23,

And a spring 26 for elastically supporting the housing 21 and suppressing vibration transmitted to the housing 21 by the diaphragm 25.

Particularly, the bone conduction unit 20 of the present invention precisely aligns the tolerance between the vibration coil 22, the magnetic body 23, and the housing 21 to one hundredth of an inch, thereby preventing the magnetic loss due to the clearance gap to the utmost .

In this case, the diaphragm 24 is made of a phosphor bronze material, thereby improving the elasticity generated during vibration than the stainless steel (SUS) material used as a diaphragm material of a conventional bone conduction acoustic device, thereby widening the width of the sound band.

Particularly, when a stainless steel material is used, the stainless steel is stiff due to the power supply, so that the vibration is not smoothly generated and the sound is broken. However, the present invention solves the above problem by using the phosphor bronze.

The housing 21 is screwed and fixed to the hard case 14 and 15 built in the warming portions 11 and 12 and is fixed to the outside of the warming portion 11 by a spring 26 provided inside, (I.e., the inner side of the base 12).

The vibration transmitted to the housing 21 when the diaphragm 25 vibrates due to the interaction between the vibration coil 22 and the magnetic body 23 is suppressed by the strong elastic force of the spring 26, Is concentrated only on the diaphragm (24), sound can be transmitted with higher quality.

That is, even if the housing 21 is fixedly coupled to the hard cases 14 and 15, the vibration is transmitted to the housing 21 as the diaphragm 25 vibrates,

In the conventional bone conduction acoustic apparatus, vibrations of the diaphragm 25 and the housing 21 are generated at the same time, and vibrations of the diaphragm 24 are not sufficiently transmitted to the skull due to mutual vibration overlapping or vibration canceling action. However,

The present invention solves the above-mentioned problem by suppressing the vibration of the housing (21) using the spring (26)

The bone conduction unit 20 of the present invention has a minimum diameter of 14 pie and a minimum diameter of 14 pie. However, in the conventional bone conduction acoustic equipment, The impedance of the same 8 ohm as the conventional antenna can be obtained even if the antenna is manufactured to have a height of 8 mm, so that the bone conduction unit 20 can be miniaturized and high quality sound can be delivered.

4, the driving unit 30 includes a wireless module 31, an acoustic processing unit 32, a control unit 33, a battery 34, and a controller 35.

The wireless module 31 wirelessly receives an acoustic signal and an operation signal for controlling the drive unit 30 from a portable device such as a smart phone or MP3. The wireless module 31 can wirelessly communicate using Bluetooth, ZigBee, NFC, or the like.

The sound signal received by the wireless module 31 is transmitted to the sound processing unit 32, and the operation signal is transmitted to the control unit 33.

The sound processing unit 32 demodulates and amplifies an acoustic signal transmitted through the wireless module 31, and outputs the amplified sound signal to the bone conduction unit 20.

The first moving magnet 42 is divided into N and S poles in the left and right directions,

The second moving magnet 44 is separated from the first moving magnet 42 by reversing the N and S poles in the left and right directions,

The N-pole and the S-pole of the stationary magnet 45 are arranged in the same direction as the second moving magnet 44 in the left-right direction (the N-pole and the S- (Which is the same as the polarity direction of the polarizer 44).

Therefore, as shown in the upper right section of [A] in Fig. 5, in a state in which the moving block 41 is moved to one side (right side in the figure) by the spring 26, the hook portion 17b is moved to the first moving magnet 41 The first and second moving magnets 42 and 44 face each other with a different polarity, so that the attractive forces of the first and second moving magnets 42 and 44 are opposite to each other , The lock of the cover 17 is maintained,

In this state, when the user moves the moving block 41 to the other side (left side in the drawing) by using the moving lever 41a with one hand as shown in the lower right section view of [A] in FIG. 5, (N-poles in the figure) of the first moving magnet 42 and the second moving magnet 44 are opposed to each other and a repulsive force acts between the first moving magnet 42 and the second moving magnet 44 to unlock the cover 17 So that the user can rotate the cover 17 in one opening direction (right clockwise direction in the figure) by using the other hooking groove 17a.
