Description

Speaker type headphone for helmet {Speaker Type Headphone}

[0001] The present invention relates to a speaker-type headphone for a helmet, and more particularly to a speaker-type headphone for a helmet which is detachably coupled to a helmet, and in which a sound signal transmitted from the body is outputted through a speaker attached to the inner wall of the helmet Speaker type headphone.

In general, there are two ways in which people can hear sound: air conduction and bone conduction.

Among them, the air conduction method is a method in which sound is transmitted to the inner ear through the eardrum, and the vibration of the sound transmitted to the air is transmitted to the eardrum in the ear and is transmitted through the three bones Is conveyed to the "wow".

Therefore, the wah (cochlea) is filled with a liquid called lymphatic fluid, and the vibration of the liquid is converted into an electric signal, which is transmitted to the auditory nerve, so that the human brain recognizes the sound.

Air conduction type earphones and headphones can not hear outside noise by using their ears. By using air conduction type earphones and headphones to prevent ears from being used in advanced countries, And to prevent them from listening to it.

In addition, air conduction type earphones or headphones can not be worn when wearing a helmet.

A conventional technique such as Registration Practical Utility Model No. 20-0401222 " Music Helmet with Audio Player Function ", Registered Utility Model No. 20-0213413, " Helmet with MFP 3 function " A built-in sound system is built in to allow the user to listen to the sound while wearing the helmet.

However, the method of embedding a sound device in a helmet increases the manufacturing cost of the helmet, and it is difficult to maintain the sound device when a trouble occurs in the sound device.

[ 2 detachment grooves 142. As shown in Fig. At this time, the second detachable groove 142 provided on the upper surface of the mount is provided on the rotation line of the second detachable protrusion 141 when the insertion portion 121 of the main body is inserted into the hollow portion 112 of the mount and rotated.

The second detachable groove 142 is formed with a recessed portion 142a which is formed at one side surface and the upper surface of the mount 110 so that the second detachable protrusion 141 of the main body can be pulled in through the side surface of the mount 110, And a locking protrusion 142b which is provided in the lead-in groove 142a and engages the second detachable protrusion 141. [

Here, the second detachable protrusion 141 of the main body is provided with a retaining groove 141a which is engaged with the locking protrusion 142b in the lead-in groove.

The locking protrusion 142b in the lead-in groove has an inclined surface facing the entrance side of the lead-in groove so that the second lead-out protrusion 141 enters the lead-in groove 142a, (Not shown).

The locking protrusion 142b is connected to the operating lever 143 protruding from one side of the mount and is inserted into the inner side wall of the inlet groove 142a according to the operation of the operating lever 143. [

That is, when the second detachment protrusion 141 of the main body is inserted into the second detachment groove 142a, which is the second detachment groove 142, the second detachment means 140 enters the inclined surface of the locking protrusion 142b, The engaging groove 141a formed on the engaging protrusion 141 is engaged with the locking protrusion 142b to engage the other side of the body 120 with the other side of the mount 110. [

When the main body 120 and the mount 110 are separated from each other, when the operating lever 143 protruding from one side of the mount 110 is pressed, the locking protrusion 142b is drawn into the inner side wall of the inlet groove 142a, 2 release the detachment of the detachment protrusion 141. When the main body 120 is rotated in the other direction, the second detachable protrusion 141 is separated from the second detachable groove 142 and at the same time, the first detachable protrusion 131, which is the first detachment means, The first detachment protrusion 131 is separated from the first detachment groove 132 by separating the first detachment protrusion 131 from the first detachment groove 132b.

The speaker-type headphone 100 for a helmet configured as described above is characterized in that the mount 110 and the main body 120 are attached to the surface of the helmet 1 and the speaker 150 is attached to the inner surface of the helmet 1 near the wearer's ear Respectively.

5, when the insertion portion 121 of the main body 120 is inserted into the hollow portion 112 of the mount, the first attachment / detachment protrusion 131 of the main body 120 is inserted into the hollow portion 112 of the mount, To be inserted into the entry groove 132a formed in the inner surface. The other side of the main body 120 is positioned in a diagonal direction with respect to the mount 110. The second detachable protrusion 141 provided on the other side of the main body 120 is rotatably supported by the second detachable groove 142 of the mount, Lt; / RTI >

When the main body 120 is rotated in one direction, the first detachment protrusion 131 of the main body, which is the first detachment means, is moved to the locking groove 132b of the mount and is restrained, The second detachment protrusion 141 of the main body which is the second detachment means is fitted into the second detachment groove 142 of the mount.

When the main body 120 is detached from the mount 110, when the operating lever 143 protruded to one side of the mount 110 is pressed, the locking protrusion 142b of the inlet recess for restricting the second releasing protrusion 141 And then the main body 120 is rotated in the other direction so that the second detachable protrusion 141 is detached from the second detachable protrusion 141. [ The first detachment protrusion 131 of the main body which is the first detachment means moves from the locking groove 132b of the first detachment groove to the entry groove 132a so that the insertion portion 121 of the main body is separated from the groove 142, The main body 120 can be separated from the mount 110 by being pulled out of the hollow portion 112 of the mount.

In addition, the main body 120 is provided with a connection terminal portion 124 for connecting the speaker 150, and the speaker 150 is provided with an ear jack 151 connected to the connection terminal portion 124 of the main body. Here, although the main body 120 and the speaker 150 are connected by wire, the speaker 150 may wirelessly receive and output a sound signal from the main body 120.

In addition, as shown in FIG. 6, a microphone 160 may be further connected to the ear jack 151 of the speaker for receiving a voice signal, transmitting the voice signal to the wireless terminal through the controller and the wireless module, and supporting the voice call with the wireless terminal .

As described above, according to the present invention, the mount is attached to the surface of the helmet, and the body is detachably coupled to the mount by the first and second attaching / detaching means, thereby improving the convenience of use.

In addition, it is possible not only to listen to the sound while wearing the helmet, but also to maintain the stable attachment state of the bone conduction headphone to the wind load due to the motorcycle running.
