Bone conduction earphone pasted with ear and using method thereof

Technical Field

The present application relates to the field of electronic devices, and in particular, to an ear-contacting bone conduction earphone and a method for using the same.

Background

The bone vibration device is a transducer for converting electric oscillation into mechanical vibration, the bone conduction earphone utilizes the principle of the bone vibration device, and the bone conduction indicates that the skull at the head of the bone responds to audio frequency and high-frequency vibration, transmits the audio frequency and receives audio frequency 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 ossicles 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 allows audio information to be transmitted in this particular manner because the bones of the temporal bone (temporal bone) and the maxilla bone (maxillary bone) of the cochlea (cochlea) are stimulated to be connected together throughout.

The existing bone conduction earphone mainly depends on the vibrator to contact the temporal bone and jaw bone in front of the external auditory canal to vibrate, so that the temporal bone of the cochlea is stimulated to conduct and vibrate information to the auditory nerve. The oscillator directly contacts temporal bone and jaw vibration, has following characteristics:

1. the density of temporal bones and jawbone bones is high, the requirements on resonance frequency and amplitude are high, and the bone conduction vibrator needs high power and high frequency to push, so that the problems of high power, unbalanced vibration, less low frequency, large magnetic circuit jitter, large distortion and the like are easily caused.

2. The oscillator is completely outside auricle, and bone conduction drives the air vibrations after shaking, can cause certain sound to put outward, and privacy nature is not enough high.

3. The temporomandibular joint is positioned in front of the external auditory canal, the joint position structure is complex, the nerve is sensitive, and the bone conduction vibrator vibrates in the position, so that discomfort such as pruritus is easily caused.

The characteristics result in the problems that the audio frequency range of the existing bone conduction earphones in the market is small, the audio frequency range is mainly concentrated between 0.2 and 3kHZ, the low frequency is poor, the volume is insufficient, the privacy is poor, discomfort exists and the like.

Detailed Description

The present application is described in further detail below with reference to figures 1-9. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

The embodiment of the application discloses a bone conduction headset of pasting ear.
