Description

Vibration output device provided in the user wear equipment

The present disclosure relates to a vibration output device provided in user wear equipment.

Recently, products using the bone conduction technology, which is widely known as being mounted on a mobile phone, have been appearing one after another. Various electronic devices using bone conduction technology, for example, applications such as speakers or hearing aids are commercially available. Temuco Japan, which holds patents related to bone conduction, plans to launch products that use bone conduction technology such as speakers and microphones that can be used in a vacuum and can be used anywhere in the water.

In general, the sound is recognized as the vibration of the air echoes the eardrum and the vibration is transmitted to the cochlea. Bone conduction, on the other hand, transmits vibrations directly from the bone to the cochlea. It is because of this principle that the sound is heard even when the ears are closed. Because of this, even if the eardrum and disorders, if the cochlea and auditory nerves are normal, you can hear the sound in the bone conduction.

On the other hand, when listening to music with earphones while enjoying rough sports such as snowboarding or skiing, the user does not grasp the surrounding situation and the probability of a safety accident is increased. In addition, the earphone has the disadvantage that the ear can be pulled out of the ear, and while listening to music can not hear the conversation of others.

In order to solve this problem, the research on the device that can hear the sound without going through the eardrum recently. In addition, research is being conducted on a device that allows a user to grasp the surroundings while listening to music and to listen to the conversations of others while listening to music.

The user wearing equipment 2000 may include an opening through which at least a portion of the vibration output unit 130 may be exposed. For example, the vibration plate 40 of the vibration output unit 130 may be exposed to the outside through the opening of the user wearing equipment 2000. In this case, the opening of the user wearing equipment 2000 may be larger than the size of the vibration output unit 130 to form a gap with the vibration output unit 130.

Appearance and components of the vibration output device 1000 are only embodiments of the present invention, but are not limited thereto.

3 illustrates a lower structure of the vibration output device 1000 provided in the user wearing equipment 2000 according to an embodiment of the present invention.

Referring to FIG. 3, the vibration output device 1000 may include a vibration plate 120, a vibration output unit 130, a suspension 140, and a fixing unit 170 according to an embodiment of the present invention.

Suspension 140 may include a suspension body and at least two legs. The suspension body may be attached to at least a portion of the vibration output unit 130 and may include a circular shape. The leg portion of the suspension may be formed on the outer side of the main body in a curved shape. For example, the suspension 140 may be provided with a circular suspension body and two curved legs. The suspension body and the suspension leg may be integrally molded.

Suspension 140 may be provided with only the leg portion without the suspension body. For example, the suspension 140 may be provided with only two legs. In this case, the leg portion of the suspension 140 may include a leg body 141 that can be attached to at least a portion of the vibration output unit 130, at least one extending bent from the leg body 141 It may include more than one leg (142).

At least two leg portions of the suspension 140 may include a fourth insertion hole at one end of each leg 142. In this case, the suspension 140 may be fixed to the user wearing equipment 2000 through the fixing means 170.

For example, when the suspension 140 is provided with a suspension body and a suspension leg, the suspension leg of the suspension 140 is fixed to the user wearing equipment 2000, and the suspension body is the diaphragm 120 and the vibration output unit 130. ) Can be connected. In this case, a spatial gap may be formed between the diaphragm 120 and the user wearing equipment 2000 and between the vibration output unit 130 and the user wearing equipment 2000.

For another example, when the suspension 140 is provided with only the suspension leg, the suspension 140 is a leg of the leg is fixed to the user wearing equipment 2000, the leg body is the diaphragm 120 and the vibration output unit ( In connection with the 130, a spatial gap may be formed between the diaphragm 120 and the user wearing device 2000 and between the vibration output unit 130 and the user wearing device 2000.

When a spatial gap is formed between the vibration output unit 130 and the user wearing equipment 2000 and between the vibration plate 120 and the user wearing equipment 2000, the suspension 140 may vibrate the vibration plate 120 and output the vibration. The unit 130 may reduce the loss of vibration generated by contacting the user wearing equipment 2000. As the suspension 140 reduces the loss of vibration of the vibration output unit 1000, the user can clearly hear the sound.

4A to 4E show the configuration of the vibration output device 1000. 4A to 4C show the vibration output device 1000 in an exploded view, and FIGS. 4D to 4E show a part of the vibration output device 1000 assembled.

The front case 110 may have an opening formed at a central portion thereof. The opening may include one hole and at least one step. For example, the opening may include one hole and two steps.

The diaphragm 120, the vibration output unit 130, and the suspension 140 may be located in the opening. The hole included in the opening may be formed so that the diaphragm 120 is exposed to the outside. Due to this, the diaphragm 120 may be in contact with the user wearing equipment. In addition, the diaphragm 120 may contact the head of the user.

The hole included in the opening may be larger than the size of the diaphragm 120 so that a gap Gap is formed between the diaphragm 120 and the front case 110.

At the edge of the opening of the front case 110, a first step may be formed to be close to the front part and a second step may be formed to be close to the rear part of the front case 110.

The front case 110 may include a gap between the first step and the second step. When the suspension 140 vibrates according to the vibration generated by the vibration output unit 130, a gap between the first step and the second step may provide a space in which the suspension 140 may vibrate. Therefore, even when the suspension 140 located in the front case 110 is vibrated, vibration may not be transmitted to the front case 110.

The second stepped portion formed on the rear side of the stepped portion included in the opening may form a space in which the suspension 140 and the suspension fixing case 150 may be located. The stepped portion formed on the rear surface may include at least two or more fifth insertion holes. Suspension 140 may be fixed to the front case 110 by the fixing means 170 is inserted through the fifth insertion hole.

However, the present invention is not limited thereto, and the vibration output unit 130 may be connected to the suspension 140 without the support means 160.

The suspension 140 may be attached to the rear surface of the vibration output unit 130. Suspension 140 is fixed to the front case 110, the vibration output unit 130 so that the vibration plate 120 and the vibration output unit 130 do not contact both the front case 110 and the rear case (180, 190). ) And the front case 110 can be connected. Suspension 140 is connected to the diaphragm 120 and the vibration output unit 130 to form a gap (gap) between the front case 110 so that the diaphragm 120 and the vibration output unit 130 is the front case ( 110 can be connected so as not to contact. The suspension 140 does not transmit vibration to the

cases

110, 180, and 190 by forming a gap between the diaphragm 120 and the vibration output unit 130 and the

cases
