Description

A kind of multifunctional bone conduction earphone

technical field

The invention relates to an earphone, in particular to a multifunctional bone conduction earphone.

Background technique

In the field of earphones, there are mainly two types of sound conduction earphones. The first is air conduction earphones. Air conduction earphones are generally in-ear or cover the entire ear. Air conduction earphones emit sound waves that pass through the external auditory canal and act on the eardrum. The vibration of the eardrum, the vibration of the eardrum transmits the sound to the cochlea and the auditory nerve, the second is the bone conduction earphone, the bone conduction earphone is in contact with the human skin, the shock wave passes through the human skin and bones, and is transmitted to the cochlea and the auditory nerve. Because the air conduction earphone needs to be put into the ear or cover the whole ear, in the process of using the air conduction earphone, other sounds are shielded, and the user cannot hear other useful sounds or the other sounds heard are very small, which brings great inconvenience to the user. It is inconvenient. For example, when using air conduction earphones to answer the phone, it will affect the reception of other sounds, and the air conduction earphones will make the ears uncomfortable after using them for a long time, which will bring users a bad user experience. Bone conduction earphones pass through the skin and bones. Conducting sound, without putting it in the ear or covering the whole ear, it solves the problem of shielding other sounds by the air conduction earphone, and it will not cause ear discomfort, but if it is in a noisy environment, the external interference sound It is directly received by the user through the ear, which has certain interference to the user, affects the effect of the user receiving the sound of the bone conduction earphone, and reduces the user experience.

The left ear-hanging body 212 and the left speaker position adjustment mechanism are split and consist of multiple parts. For example, a damper adjustment mechanism is used to adjust the speaker position through the rotation of the parts on both sides of the damper. The gear set mechanism 215 can also be used. The relative rotation of the gears in the gear set is used to adjust the position of the horn.

In a noisy environment, adjust the speaker position adjustment mechanism so that the speaker body covers the ear, which can shield the external sound and avoid the interference of the external sound. The vibration of the bone conduction earphone itself will cause the tragus and other parts of the ear The vibration is transmitted to the cochlea and auditory nerve through the bones, and the vibration of the bone conduction earphone itself will also emit sound waves. Since the horn body is located outside the external auditory canal, the sound waves directly propagate in the air in the external auditory canal, causing the eardrum to vibrate. It is transmitted to the cochlea and auditory nerve. When the external sound is blocked, the bone conduction earphone itself superimposes the two methods of bone conduction and air conduction, and the amplitude of the sound increases and the sound becomes louder.

In a noisy environment, the user wants to shield the external noise to a certain extent, but also does not want to miss other useful sounds. The user can choose to adjust only one speaker position adjustment mechanism to cover the corresponding ear. When the noise mainly comes from the left side When the noise is emitted, adjust the left horn position adjustment mechanism to cover only the left ear, and when the noise is mainly emitted from the right side, adjust the right horn position adjustment mechanism to only cover the right ear.

In a relatively quiet environment, adjust the speaker position adjustment mechanism so that the speaker body is away from the ear, and only use the bone conduction function to avoid ear discomfort caused by long-term wearing. The user can also hear other sounds except the earphone sound, avoiding Other useful sounds are missed.

The present invention only needs one earphone, and can select different positions of the horn body by adjusting the horn position adjustment mechanism according to different external environments, so that the horn body covers or stays away from the ear to select the corresponding conduction mode.

The left protective cover and the right protective cover are made of flexible materials, which can be silica gel, rubber or other flexible materials, preferably flexible materials with relatively large elasticity, so as to facilitate the installation and removal of the left protective cover and the right protective cover.

The hardness of the flexible material affects the transmitted sound quality. The greater the hardness of the flexible material, the stronger the ability to transmit high-frequency vibration, and the smaller the hardness of the flexible material, the stronger the ability to transmit low-frequency vibration. Different sound quality can be obtained by selecting flexible materials with different hardnesses. The hardness of the flexible material is preferably 35-55 Shore hardness, more preferably 40-50 Shore hardness, and further preferably 42-48 Shore hardness.

The protective cover is detachably arranged on the earphone body. The earphone body includes a left earphone body 21 and a right earphone body.

When the protective cover is assembled on the earphone body, the protective cover at least covers the outer surface of the part of the speaker body facing the user. The flexible protective cover can transmit vibration and has the function of a vibration transmission layer, so the vibration transmission layer can be omitted. The thickness has a certain influence on the transmitted sound quality. The thicker the protective cover is, the greater the mass is, the lower the resonance frequency is, and the bass effect is obvious. The thinner the protective cover is, the smaller the mass is, and the higher the resonance frequency is, the treble effect is obvious. , the thickness of the protective sheath is 0.1mm-1.5mm, preferably the thickness of the protective sheath is 0.15mm-0.8mm, and more preferably the thickness of the protective sheath is 0.2mm-0.5mm. Users can choose protective covers of different thicknesses according to their preferences for high and low sounds.

One end of the first rotating arm 2151 is fixed on the first gear 2152, the other end of the first rotating arm 2151 is fixed on the first ear-hanging body, one end of the second rotating arm 2153 is fixed on the second gear 2154, and the second rotating arm 2153 The other end of the ear hook is fixed on the second ear hook, and the first gear 2152 meshes with the second gear 2154. When the external force pushes the first ear hook, the first gear 2152 rotates around the second gear 2154 to change the position of the horn.

As a deformation method, the first rotating arm 2151 and the second rotating arm 2153 are hinged together, the first gear 2152 and the second gear 2154 mesh, the first gear 2152 is fixed on the first rotating arm 2151 and cannot rotate, and the second The gear 2154 is rotatably fixed on the second rotating arm 2153. When the external force pushes the first ear hanger, the first gear 2152 drives the second gear 2154 to rotate to realize the change of the horn body position.

It is also possible to directly fix the first ear-hanging body to the first gear 2152, cancel the first rotating arm 2151, directly fix the second ear-hanging body to the second gear 2154, and cancel the second rotating arm 2153.
