The present invention relates to an earphone, and more particularly, to an earphone capable of realizing multiple sounds by one speaker.

Earphones are small devices that convert electrical signals into acoustic signals that can be plugged into or close to the ear, and are used only when listening alone in portable radios, hearing aids, and, in general, small devices for listening to music.

Conventional techniques relating to earphones are disclosed in a number of published documents, including Korean Utility Model Registration No. 20-0283124 (designation: Earphone).

Such earphones are operated while a speaker element for reproducing an electrical signal to sound is fitted on the ear canal side so that the sound can be heard by vibrating air in the inner ear canal space. However, the characteristics of the speaker element are faithful to the reproduction of the range of the specific range, but not so effective for the reproduction of the range beyond or below the specific range, and it is difficult to listen to the three-dimensional sound by the earphone.

On the other hand, the human hearing path can be divided into the path of stimulating the auditory nerve through the eardrum and the path of stimulating the auditory nerve through the bone, and the bone conduction that enables hearing by vibrating bone for the hearing impaired due to the defect of the eardrum. The speaker is disclosed in Korean Patent Laid-Open Publication No. 2002-0086580 (name of the invention: Galdospeaker) and the like. In general, in such a bone loudspeaker, the sound transmitted through the bone is faithful to low-end sound reproduction, but not so effective for high-end reproduction.

Therefore, the Republic of Korea Utility Model Registration No. 20-0253605 (name of the design: headphone with surround function), a pair of air conduction speaker and bone conduction to listen to sound by vibrating the eardrum through air conduction Disclosed is a technology related to a headphone composed of a pair of bone conduction speakers that can hear the sound by vibrating the bone through.

Such a headphone technique also requires wearing the bone conduction speaker to be closely attached to the bone formation part of the temporal part, and then putting the air conduction speaker on the ear canal side, that is, the hassle of wearing, and the bone conduction speaker faces Because it is disposed on the front side of the, it is not good for the aesthetic appearance. In addition, in the case of such headphones, since there is a connecting element that elastically connects the left and right sets of bone conduction speakers and the air conduction speakers, it is mechanically possible to configure the bone conduction speaker and the air conduction speaker as a pair, and thus, conventionally In the case where there is no connection element that elastically connects the left and right speaker elements with an acoustic device known as an earphone, since the technology related to the headphone cannot be applied, it is difficult to reproduce three-dimensional multi-sound with conventional earphones. .

An object of the present invention is to provide an earphone capable of realizing the reproduction of the multiple sounds of the earphone, which cannot be solved in the related art as described above.

Furthermore, another object of the present invention is to provide earphones that are easy to wear while enabling reproduction of multiple sounds.

In addition, another object of the present invention is to provide earphones that can realize reproduction of multiple sounds while having a good aesthetic appearance.

Earphone according to the present invention for achieving the above object, the connector (Connector) connected to the AV (Audio-Video) device; An air conduction speaker that receives the first electrical signal received from the AV device through the connector and vibrates air in the inner ear canal space through air conduction; A first casing fitted to the external auditory meatus while supporting the air conduction speaker; A bone conduction speaker that receives the second electrical signal received from the AV device through the connector and vibrates the bone; A second casing for supporting the bone conduction speaker; A connection line which transmits a first electrical signal received from the connector to the air conduction speaker and a second electrical signal received from the connector to the bone conduction speaker; And a connection end connected to the first casing and the second casing to be integrally fixed, and wherein the bone conduction speaker is in close contact with the skin when the first casing is fitted to the ear canal. Characterized in that it comprises a.

In addition, the connecting end is formed to extend from the first casing to the rear head side after protruding from the first casing, so that the bone conduction speaker is arranged on the rear side of the face.

In addition, the connection end is preferably provided with an elastic body so that the bone conduction speaker can be firmly in close contact with the skin.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention, it looks at in more detail with respect to the present invention.

1 is a perspective view of an earphone 100 according to an embodiment of the present invention.

Referring to FIG. 1, the earphone 100 according to the present invention includes a connector 11, an air conduction speaker 12, a first casing 13 for receiving an air conduction speaker 12, and the first casing. 1, the cover 14 covering the open front end of the casing 13, the bone conduction speaker 15, the second casing 16 for supporting the bone conduction speaker 15, and received from the connector 11 Connecting lines 17, 17a, and 17b for transmitting electrical signals to the air conduction speaker 12 and the bone conduction speaker 15, and the first casing 13 and the second casing 16 are integrally fixed. It comprises a connecting end 18 or the like.

The above-described configuration will be described in more detail as follows.

The connector 11 is a terminal connected to the AV device. Here, the AV device may be a radio, a cassette, a computer or a mobile communication device capable of listening to music. The connector 11 receives a first electrical signal and a second electrical signal for sound reproduction from the AV device. The first electrical signal is an electrical signal for sound reproduction in a high range, and the second electrical signal is an electrical signal for sound reproduction in a low range. Therefore, the first electrical signal is transmitted to the air conduction speaker 12, which will be described later, and the second electrical signal is transmitted to the bone conduction speaker 15, which will be described later.

The air conduction speaker 12 receives the first electrical signal received from the AV device through the connector 11 to vibrate air in the inner ear canal space through air conduction. In general, since the reproduction of the sound range through air conduction is effective for the reproduction of the high sound, the air conduction speaker 12 receives the first electric signal received from the AV device through the connector 11 and reproduces the high sound.

The first casing 13 is fitted to the ear canal side of the ear while supporting the air conduction speaker 12. The sound generated by the vibration generated from the air conduction speaker 12 spreads to the front to spread the eardrum through the ear canal. Shear is open to stimulate.

The cover 14 is provided to cover the open front end of the first casing 13 in order to protect the air conduction speaker 12 supported by the first casing 13 from the outside. Of course, the cover 14 is formed with a plurality of passage holes 14a so that the air vibration generated through the air conduction speaker 12 can spread toward the front of the first casing 13.

The bone conduction speaker 15, by vibrating the bone (骨) through the skin of the back of the head, to stimulate the auditory nerve through the bone to be able to hear the sound. In general, hearing through the bones is effectively transmitted in the low range. Therefore, the bone conduction speaker 15 receives the second electrical signal received through the connector 11 from the AV device to reproduce the bass sound. In addition, since the bone conduction speaker 15 can be disposed on the back of the head of the person behind the ear, the bone conduction speaker 15 is not visible in the appearance of the person observed from the front.

The second casing 16 is open to the front so that the vibration generated by the bone conduction speaker 15 can be transferred to the bone through the skin of the back of the head while supporting the bone conduction speaker 15.

The connection lines 17, 17a, and 17b transmit a first electrical signal received from the connector 11 to the air conduction speaker 12, and transmit a second electrical signal received from the connector 11. The element is delivered to the bone conduction speaker (15).

The connection end 18 may be in close contact with the bone conduction speaker 15 when the first casing 13 supporting the air conduction speaker 12 is fitted to the ear canal side of the ear. The first casing 13 and the second casing 16 are connected to each other so as to be integrally fixed.

In addition, the connecting end 18 is formed so as to protrude from the first casing 13 and extend to the rear head side after covering the auricle, so that the bone conduction speaker 15 is arranged at the rear side of the face.

In addition, the extended end is more preferably provided as an elastic body. Because, the shape of the back of the head may be different according to the shape of the user's skull, when the arbitrary user inserts the first casing 13 to the ear canal side, the bone conduction speaker 15 by the elastic force of the extended end is This is because the adhesion of the air conduction speaker 12 is further improved by being able to be integrally attached to the skin of the laryngeal region.

Depending on the application, the connecting end may be formed so that the bone conduction speaker is disposed on the front side and the temporal side of the face, but it is more preferable to be disposed on the laryngeal side in appearance.

On the other hand, the first casing 13, the second casing 16 and the connecting end 18 may be integrally injection molded, but after injection into a separate component, it may be to be fixedly coupled to each other.

The use and operation of the speaker configured as described above will be described with reference to FIG.

As shown in FIG. 2, the user completes the wearing by fitting the first casing 13 supported by the air conduction speaker 12 to the ear canal side while the connecting end 18 spans the ear wheels. . At this time, since the second casing 16 supporting the bone conduction speaker 15 is integrally connected to the first casing 13 through the connecting end 18, the first casing 13 is supported by the ear wheels. With the wearing of the bone conduction speaker 15 is also in close contact with the skin of the larynx naturally. At this time, since the connecting end 18 has elasticity and closely adheres the second casing 16 to the back of the laryngeal region, the bone conduction speaker 15 can be stably in close contact with the skin regardless of the skull shape of the user.

On the other hand, when the user wears the earphone 100 before or after connecting the connector 11 to the AV device output terminal, the first electrical signal for reproducing the high-frequency band output from the AV device is the connector 11 and the connecting line 17. The air conduction speaker 12 vibrates the air in the inner ear canal space according to the air conduction speaker 12 through 17a. Therefore, the sound of the high band is transmitted to the auditory nerve through the eardrum, so that the user can hear the high band.

In addition, the second electrical signal for reproducing the low frequency band output from the AV device is input to the bone conduction speaker 15 via the connector 11 and the connection lines 17 and 17b, whereby the bone conduction speaker 15 is Vibrate the bones through the skin of the larynx. Therefore, the low-end sound is transmitted to the auditory nerve through the skull (bone) of the back of the head region so that the user can hear the low-end band.

By splitting the high and low bands through two human hearing paths as described above, the user can listen to the sounds of the high and low bands more faithfully and listen to the three-dimensional sound. .

On the other hand, since the above embodiments are only examples of the present invention, the present invention should not be construed as being limited to the above embodiments. In other words, the present invention should be construed as having a technical spirit that includes the contents described in the claims to be described later and the equivalent ranges of such contents.

According to the earphone according to the present invention as described in detail above, it is possible to hear the multiple sound by one earphone, and second, it is easy to wear while implementing the reproduction of the multiple sound, and the user appearance when worn by the user The sense of taste has a good effect.
