Technical Field
The present invention relates to a listening device using bone conduction that recognizes a sound by applying vibration to a bone, and more particularly to a listening device that can be worn reliably without recognizing a wearing position when worn.
Background
Conventionally, devices for listening to music or sounds of radio sets, televisions, and the like, such as headphones and earphones, which are worn on the ears and used for listening to music, or for listening to a conversation wirelessly using a mobile phone (hereinafter referred to as listening devices) have been widely used.
For example, in a listening device, a general headphone is composed of a device to be worn in an ear hole, a device to cover the entire ear, and the like, and the following structure is used: a sound source inputted as an electric signal is converted into air vibration, transmitted to the eardrum, vibrated, and recognized by transmitting sound information to the brain through vibration of the eardrum.
However, in recent years, there has been developed a listening device using bone conduction in which sound is recognized by vibration of bones and vibration of the bones is given to the skull, and the listening device is not configured to vibrate the eardrum by air vibration as described above. Listening devices using bone conduction do not need to be inserted into ear holes as in headphones and earphones, and therefore, are safe to wear because they are inserted into the ears without shielding surrounding sounds, and also, because a person with reduced hearing can recognize sounds without using vibration of the tympanic membrane, and use of hearing aids and the like has been advanced.
The listening device using bone conduction converts an acoustic signal input as an electrical signal into mechanical vibration, applies the vibration to a bone from an appropriate position, transmits the vibration to the bone, recognizes a sound using bone conduction sound transmitted by the vibration,
as the appropriate position, a periphery of the temple, a large protrusion periphery located posterior and inferior to a temporal bone called a mastoid, may be cited.
Since the periphery of the temple is the skull itself, and if the vibrating portion is brought into sufficient contact with the periphery of the temple, the sound vibration can be accurately applied to the bone, a device that comes into contact with the temple is widely used in listening devices using bone conduction, particularly in headphone types.
In addition, in the listening device using bone conduction of this type, it is important that the vibrating portion accurately contact the periphery of the temple, and therefore, the listening device has an arm shape that can be used by being hung on the upper portion of the ear.
On the other hand, as a device for applying vibration to the mastoid rather than the periphery of the temple, for example,
The device having a structure for imparting vibration to the periphery of the temple and the device having a structure for imparting vibration to the mastoid as described above can be worn without being inserted into the ear as described above, and can therefore be worn safely without blocking surrounding sound, and can also listen to sound even by a hearing impaired person.
Disclosure of Invention
Problems to be solved by the invention
As described above, the listening device using bone conduction can listen by bringing the vibrating portion into contact with an appropriate position. Further, in order to transmit vibration from the vibrating portion in contact with an appropriate position to the bone, a certain degree of contact pressure must be applied, and therefore fastening is required. This is because vibration cannot be transmitted well to the extent that the fastening is weak and only contact is made, and it is difficult to recognize sound.
Therefore, in the listening device using bone conduction in which the vibrating portion is brought into contact with the periphery of the temple, the vibrating portion is structurally designed to be brought into contact with the periphery of the temple by applying sufficient pressure thereto with precision (pinpoint), and it is necessary to pay attention to the arrangement of the vibrating portion at an appropriate position in the periphery of the temple when the listening device is worn.
In addition, when the vibrating portion is displaced from the proper position due to unstable wearing, the vibrating portion must be adjusted to contact the proper position again.
On the other hand, fig. 11 is a drawing for explaining the prior art, and shows a device of
Therefore, the positions of the mastoids are not uniform, and therefore, there is also a problem in that: it is necessary to arrange the vibrating portion and adjust the position of contact, and it is necessary to prepare several kinds of devices having different sizes in accordance with the physical characteristics of the wearer, and it is necessary to manufacture them in order according to the use purpose, which hinders the popularization of the voice recognition device using bone conduction.
However, conventionally, listening devices using bone conduction have been used to compensate for hearing loss, particularly for persons having problems with the eardrum and having difficulty in converting a sound source input as an electrical signal into air vibration and transmitting the air vibration to the eardrum for vibration.
However, in recent years, hearing devices using bone conduction have attracted attention because they do not block surrounding sound and are highly safe because they do not fit into ear holes, and their use by hearing-healthy people has increased when they are introduced into mobile phones.
However, in the case of a person with a healthy hearing, when sound from bone conduction is transmitted, sound entering from the ear hole is simultaneously transmitted to the eardrum, and therefore, if noise exists around the person, the noise entering from the ear hole and the sound from bone conduction are mixed, and the sound from bone conduction is blocked, which is rather difficult to hear.
To cope with such a problem, it is necessary to wear an earplug or to plug the earhole with a finger, losing the meaning of utilizing bone conduction.
Accordingly, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a listening device using bone conduction, which can be easily and simply worn by not only a hearing impaired person but also a hearing healthy person, and which can sufficiently listen to sound by bone conduction.
Means for solving the problems
The present inventors have conducted extensive studies in order to achieve the above object, and as a result, invented a device as described below.
(1) A listening device is provided with: a bone conduction driver that converts the acoustic electrical signal into vibrations; a vibration output structure that outputs the vibration converted by the bone conduction driver; and an ear hook member which is disposed above a frame body that houses the bone conduction driver, and which is engaged with the above pinna so that the vibration output structure is disposed between the rear portion and the temporal portion of the pinna, and has a length that abuts against the rear portion of the pinna within a range from above to below the rear portion of the pinna.
(2) A listening device is provided with: a bone conduction driver that converts the acoustic electrical signal into vibrations; a frame that houses the bone conduction driver; a vibration output structure which is detachably provided in the housing and outputs the vibration converted by the bone conduction driver; and an ear hook member provided to the housing.

Effects of the invention
(1) The listening device according to the present invention comprises: a bone conduction driver that converts the acoustic electrical signal into vibrations; a vibration output structure that outputs the vibration converted by the bone conduction driver; and an ear hook member which is disposed above the frame body housing the bone conduction driver, and which is engaged with the above of the pinna so that the vibration output structure is disposed between the rear portion and the temporal portion of the pinna, and which has a length that is abutted in a range from the above of the rear portion to the below of the pinna, so that the ear hook member can be worn easily and reliably without being aware of the wearing position regardless of the characteristics of the body of the wearer or regardless of the hearing-healthy person or the hearing-impaired person.
Further, since the listening device can be worn by being arranged only between the rear portion and the temporal portion of the pinna, the listening device does not receive a pressure due to fastening, does not shift even when moved slightly, is small and lightweight, has excellent design properties, can be easily worn and removed, and has excellent comfort when worn.
Further, since the vibration from the vibration output structure is transmitted from the temporal portion to the skull bone and from the rear portion of the pinna to the entire pinna to vibrate the air around the ear hole, the sound from the bone due to the bone conduction and the sound due to the air vibration from the ear hole can be simultaneously heard, and the sound can be clearly heard.
Further, since the hearing device uses bone conduction, it does not block the ear hole, is highly safe, and can be used in various fields such as a helmet and the like which can realize a conversation in a work site with intense noise, such as a headphone and a microphone, a hearing aid, and the like.

In particular, the vibration output structure can be appropriately selected and attached to the housing in consideration of age, gender, head shape, ear shape, and the like.
