Description

Bone conduction earphone capable of being positioned and explained

Technical Field

The invention belongs to the technical field of earphones, and particularly relates to an earphone capable of positioning and explaining bone conduction.

Background

The concept of sound bone conduction is known by general public mostly from the release of google glass, and after the release of google glass in 2013, in addition to increasing visual functions which cannot be realized by mobile phones, the concept of sound bone conduction attracts attention of many people through a special mode of sound transmission by a Bonneconnection transmitter. In fact, sound bone conduction has a mature principle system and practical application in life and medical treatment. The study of bone-conduction sounds began in Barany, Herzog et al, the second and thirty decades ago. In 1950, pumphey first reported that humans can sense ultrasound up to 120kHz through bone conduction.

Bone conduction refers to the process of responding to audio and high-frequency vibration of the skull on the head, transmitting and receiving audio signals through auditory organs. Generally, the way in which a human body acquires audio information is air conduction of sound. The process is as follows: the auricle collects sound wave information, the audio information is transmitted to the tympanic membrane from the external auditory canal, the vibration is transmitted to the ossicle by the tympanic membrane, the vibration information is transmitted to the cochlea and the semicircular canal, the processed information enters the nerve endings, and the nerve endings information enters the brain. The bone conduction uses the skull and jaw bone as the medium of sound conduction, and information is directly transmitted to the middle ear. Bone conduction is the reason why audio information can be transmitted in this particular way is that the skull, including the temporal bone (temporalbone), which can stimulate the cochlea (cochlea), is entirely connected together.

The use of cochlear stimulation by bone conduction has been widely used in hearing tests to distinguish between hearing loss from damage to the ear canal in the external auditory canal or to damage such as receptors at the level of nerve cells. Bone conduction is effective for conductive hearing problems (i.e., loss of the ear canal transmission link in the external auditory canal). Bone conduction now also has some role in tinnitus treatment, such as long-term residual inhibition

When the outer ear and the middle ear of the human body are affected with pathological changes, the bone conduction can replace part of the function of air conduction. It is well known that bazedoxifene attempts a method of geovani philippie ingersia after hearing loss: biting a rod connected with the piano to regain the sound and continue the creation of the piano; in 1923, an engineer named Hugo Gernsback has begun to make hearing aids based on bone conduction theory. At present, bone conduction sounding is actually used in the medical industry and in various aspects of life in the form of earphones and the like. In 6 months 2013, the german broadcaster Sky Deutschland co-operated with the advertising company BBDO, also used bone conduction for the first time for commercial advertising projects. They spread advertising by bone conduction to passengers who head on subway windows, and by the vibration of the glass, advertising messages to potential consumers.

At present, the traditional earphone that uses on the market mostly all is earplug formula, packs the earphone in the ear, also has bluetooth headset, but all need hang the earphone on the ear, wear for a long time, make the ear tired easily or can bring a series of problems such as the ear is uncomfortable, the serious even can influence people's hearing of condition.

With the continuous development of earphone technology, a new earphone, a bone conduction earphone, has appeared, which transmits sound to the brain through the vibration of the earphone to the skull, can well protect the eardrum, and also reduces the pressure of the ear, so that the earphone is popularized more and more. The existing bone conduction earphones are also various and have various functions. The existing bone conduction forehead earphones mainly aim at people with hearing impairment, so that the people can realize normal hearing function by means of bone conduction characteristics. In the aspect of scenic spot explanation, the application of bone conduction earphone still is a big blank, if can be applied to the aspect of scenic spot explanation bone conduction earphone, not only can make the ear obtain idle, can conveniently listen the sound of surrounding environment.
