Disclosed is a bone conduction earphone in the form of a hair band, comprising a hair band (1). The hair band comprises a main support (11), a secondary support (12) and a casing (13). One end of the secondary support is provided with a bone conduction vibrator installation hole (121), and the other end thereof is connected to the main support. The casing is provided on an outer side of the secondary support and forms an accommodation cavity for accommodating a battery and a circuit board. The bone conduction earphone in the form of the hair band further comprises a bone conduction vibrator (3) provided in the bone conduction vibrator installation hole. The present invention adopts the bone conduction vibrator to convey sounds to auditory nerves by bone conduction, and adopts a soft rubber cover made of a biological soft rubber material to contact the human body in order to use a head bone as a conduction medium, thereby avoiding drawbacks caused by sound propagation through the air and sound reception by ears, thus causing no harm to eardrums. Furthermore, wearing the present invention as a hair band is aesthetically pleasing and fashionable, and the present invention in the form of the hair band is easy to carry and convenient to use.

Description

Hair band bone conduction earphone

Technical field

The invention relates to the technical field of earphone devices, and in particular to a hair band type bone conduction earphone.

Background technique

There are two ways of sound transmission. One is air conduction, which is called air conduction. It is the principle of using air vibration. The sound is transmitted to the eardrum and then transmitted to the inner ear nerve through the eardrum. At present, the traditional earphones on the market are made of the principle of air vibration. The earphones are attached to the ear holes, the earphones vibrate the air, and the air vibrates the eardrum of the person, and the sound is transmitted to the human brain. This kind of earphone, because it needs to stick the earphone in the ear hole when using it, when people cross the road, they can not hear the sound of the car whistle, which is quite dangerous; secondly, the traditional earphone is stuck in the ear hole in the ear canal. Form a humid and humid closed environment, the air inside the ear is blocked, the secreted sweat can not be volatilized, and the time is long, it is easy to breed a large number of bacteria, causing eardrum lesions. In addition, the conventional earphones have electromagnetic waves, which cause damage to the human brain and the hearing nerves. If the earphones are used for a long time at a large volume, the eardrum of the person is affected, which may cause human tinnitus, which may seriously cause hearing loss. At the same time, the existing earphones, wearing for a long time will make the girl's hair lift up, destroy the hair style, and it is very inconvenient to go out and wear it.

Summary of the invention

In view of the deficiencies of the prior art, the object of the present invention is to provide a hair band-type bone conduction earphone, which adopts a soft rubber sleeve made of a biological soft rubber material to contact the human body with a sound transmission mode of bone conduction. The skeleton is a conductive medium that transmits sound to the auditory nerve, while being beautiful and stylish, and easy to carry.

In order to achieve the above object, the technical solution adopted by the present invention is as follows: a hair band type bone conduction earphone comprising a headband, the headband comprising a main bracket, a secondary bracket and a casing, the secondary bracket having a bone at one end thereof Conducting the vibrator mounting hole, the other end is connected to the main bracket; the outer casing is disposed on the outer side of the sub-bracket, and forms a receiving cavity for placing the battery and the circuit board; further comprising a bone conduction vibrator, the bone conduction vibrator is disposed on the bone conduction The vibrator is installed inside the hole.

As a preferred solution, the inner side of the headband is covered with a soft rubber sleeve.

As a preferred solution, the main bracket and the secondary bracket are connected by a hinge bracket.

As a preferred solution, one end of the hinge bracket is provided with a bump, and the other end is provided with a folding head. The protrusion is disposed in the receiving cavity, and the folding head is fixed to the main bracket.

As a preferred solution, a LOGO decorative panel disposed outside the headband is also included.

As a preferred solution, the main bracket has a semicircular cross section.

As a preferred solution, the bone conduction oscillator is a BCT oscillator.

As a preferred solution, the outer casing and the secondary bracket are connected by screws, and the screws have an annealing hardness greater than 450 HRC.

As a preferred solution, the headband is provided with a gear adjustment button.

Compared with the prior art, the invention has the beneficial effects that the invention adopts a bone conduction vibrator, uses a bone conduction technology to avoid the sound propagation through the air, and the ear receives the sound, so that the eardrum is not damaged, and the hair band type is worn. Beautiful and stylish, easy to carry and easy to use.

detailed description

The invention is further described below in conjunction with specific embodiments. The following examples are only intended to more clearly illustrate the technical solutions of the present invention, and are not intended to limit the scope of the present invention.

Example:

As shown in FIG. 1 and FIG. 2, a headband bone conduction earphone includes a headband 1 including a main bracket 11, a secondary bracket 12 and a casing 13, and the secondary bracket 12 has a bone at one end thereof. The vibrator mounting hole 121 is connected, and the other end is connected to the main bracket 11; the outer casing 13 is disposed on the outer side of the sub-frame 12 and forms a receiving cavity for placing the battery and the circuit board; and further includes a bone conduction vibrator 3 for conducting the bone conduction The vibrator 3 is disposed in the bone conduction vibrator mounting hole 121; the bone conduction vibrator 3 is a BCT vibrator; and further includes a LOGO decorative plate 6 disposed outside the headband 1; the headband 1 is provided with a gear position adjustment button 14. The invention adopts the bone conduction vibrator 3, applies the bone conduction technology to avoid the sound propagation through the air, and the ear receives the sound, so that the ear membrane is not damaged, and the outer casing 13 is provided to support the protection and is provided with the LOGO decorative board 6 , increased the appearance.
