Abstract

The invention discloses an earplug type earphone by adopting a bone conduction speaker, comprising a shell of the earplug type earphone and the bone conduction speaker arranged inside the shell, wherein the shell comprises a body and a front faceplate, and the bone conduction speaker component comprises magnetic body combinations, a coil and an elastic piece. The earplug type earphone is characterized in that the elastic piece is fixed inside the front faceplate, the coil of the bone conduction speaker or one of the magnetic body combinations is fixed on the elastic piece, while another one is correspondingly fixed inside the body. The earplug type earphone by adopting the bone conduction speaker realizes the use without an external amplifier, further guarantees the amplitude amplification under the condition of the prior input power by optimizing the structure of the bone conduction speaker, optimizes the listening effect, ensures that air inside the ear channel is communicated with outside air through a through hole on the earplug and a user can listen the outside sound, guarantees the normal endaural pressure and ensures that the listener feels more comfortable.

Description

Adopt the PlayGear Stealth of bone-conduction speaker

Technical field

The present invention relates to a kind of PlayGear Stealth, particularly a kind of PlayGear Stealth that adopts bone-conduction speaker.

Background technology

Bone-conduction speaker can conduct to ear bones with vibrations by contacting with human body as listening device, makes the people hear sound, and sound need not to be vulnerable to the influence of environment through air borne, the environment around also can not influencing because volume is excessive.Yet, satisfy the vibration condition of bone-conduction speaker if desired, usually need between ordinary playing device and bone-conduction speaker, amplifier be installed, small owing to its volume for insert earphone, and common portable equipment power is less, and it is more difficult to make the vibration of bone-conduction speaker reach instructions for use.

Summary of the invention

The objective of the invention is to: a kind of PlayGear Stealth that can directly be connected the employing bone-conduction speaker on the portable equipment is provided.

Technical scheme of the present invention is:

A kind of PlayGear Stealth that adopts bone-conduction speaker, comprise the casing of lead, PlayGear Stealth and be installed in the interior bone-conduction speaker assembly of casing, casing comprises main body and front panel, bone-conduction speaker adopts modular construction, the bone-conduction speaker assembly comprises magnet combination, coil and shell fragment, it is characterized in that: shell fragment is fixed on the inside of front panel, and one in coil in the bone-conduction speaker assembly or the magnet combination is fixed on the shell fragment, and another is fixed on the inside of main body accordingly.

Supplementary technology scheme of the present invention is:

Preferably, magnet combination is fixed on the shell fragment, coil stationary with liner plate that main body is connected on.

Preferably, magnet comprises columned central magnet and the outer ring-type yoke of central magnet, in central magnet and ring-type yoke bottom opposite side the opposing inclined face is arranged.The opposite face that tilts can increase the density of line of magnetic force of sectioned coil.

Preferably, coil, liner plate are fixed on the shell fragment, and magnet combination is fixed on the main body.

Preferably, on main body, be provided with a through hole, several apertures are arranged on the front panel.

Preferably, be provided with an able to turn on or off soft lid in the main body outside with the corresponding position of through hole.

Preferably, shell fragment is a sheet metal that openwork part is arranged, and openwork part is the coupling part after removing openwork part between the central authorities of sheet metal and the periphery between the central authorities and periphery of sheet metal, at least one bending is arranged on the coupling part.And outer being with at sheet metal is no less than two stiff end.

The invention has the beneficial effects as follows: the assembly coil of bone-conduction speaker and magnet combination are separately positioned on main body and are equipped with on the front panel of shell fragment in PlayGear Stealth, vibration can directly be occurred on the front panel, contact with the direct of human body by front panel, vibration is reached ear bones, reduced the decay link of vibration, can realize need not to use between the external amplifier; Can further guarantee under the condition of existing input power, to increase amplitude by the structure of optimizing bone-conduction speaker on this basis, optimize audibility; Through hole on PlayGear Stealth can make the listener both can hear external sound so that the air in the duct is communicated with outside air, can guarantee that also the ear internal pressure is normal, makes the listener feel more comfortable; And owing to adopt the PlayGear Stealth of bone-conduction speaker can reach in the environment playing sound hardly, so with the supporting use of hearing aids the time, this kind earphone can not cause the positive feedback of hearing aids, can avoid the generation of uttering long and high-pitched sounds.
