Technical Field

The invention belongs to the field of electronic equipment, and particularly relates to an earphone capable of effectively preventing a stethoscope effect.

Background

With the continuous development of some electronic equipment such as cell-phone, walkman, when needing to appreciate music, the earphone just becomes the accessory that these electronic product are essential, however in wired in-ear earphone's use, the stethoscope effect often appears, and the stethoscope effect is that the earphone cord receives external collision or air friction, and the vibration that produces passes through the earphone cord and directly transmits to the duct in, produces the very unpleasant friction sound of letting the people.

Most traditional earphone cords are all simple direct and are connected with the earphone head, and longer earphone cord between earphone head and the player produces the stethoscope effect because of colliding the friction with the clothing externally easily, influence the use of earphone and experience, also cause uncomfortable sense to the ear easily, and moreover, most traditional wired earphone's earphone cord is generally all longer, and not only produces the stethoscope effect more easily more longer, also takes place the winding easily, is not convenient for use.

To this end, we propose an earphone that effectively prevents the stethoscope effect to solve the above problems.

Disclosure of Invention

The invention aims to solve the problem that most of the traditional earphones are easy to generate stethoscope effect and cause discomfort to ears, and provides an earphone which can protect ears and effectively prevent the stethoscope effect.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides an earphone that can effectively prevent stethoscope effect, includes earphone head and earphone cord, earphone cord fixed connection is at the lower extreme of earphone head, the lower lateral wall fixedly connected with amortization box of earphone head, the fixed plate that fixedly connected with level set up in the amortization box, the fixed plate below is equipped with the vibration board rather than parallel arrangement, the fixed permanent-magnet block that inlays in inside of vibration board, fixedly connected with antivibration spring between fixed plate and the vibration board, the one end that earphone cord kept away from the earphone head runs through the fixed plate setting and is the heliciform around establishing along the antivibration spring, the one end that the antivibration spring was kept away from to the earphone cord extends to the outside setting of amortization box, the both ends of vibration board all extend to the inboard setting of amortization box, be equipped with vibration board assorted sliding tray on the.

The invention has the beneficial effects that:

the earphone cord is the heliciform along the anti-vibration spring and winds and establish, earphone circular telegram back, when the earphone drives vibration board vibration under the effect of stethoscope effect, can drive its inside permanent magnetism piece vibration from top to bottom, can know by lenz's law, the magnetic field of the induced-current that the earphone cord on the anti-vibration spring produced always hinders the change that arouses the magnetic flux of induced-current, can hinder the vibration board from top to bottom vibration promptly, avoid in vibration conduction to the earphone head, can reduce the uncomfortable sense that the stethoscope effect made the ear to produce at to a great extent.

In the earphone capable of effectively preventing the stethoscope effect, the elastic liquid bags are fixedly connected between the sliding groove and the upper side wall and the lower side wall of the vibrating plate, and the magnetic powder with the opposite poles repelling each other is respectively contained in the liquid of the two elastic liquid bags.

When the earphone wire drives the vibration board to vibrate, the elasticity of the elastic liquid bag can buffer the vibration of a part of earphone wire, the magnetic powder with unlike poles repelling in the elastic liquid bag can fluctuate in a small amplitude, and the magnetic action between the magnetic powder can further restrain and weaken the vibration board.

In foretell earphone that can effectively prevent the stethoscope effect, the lower extreme fixedly connected with wire winding box of amortization box, rotate through the coil spring in the wire winding box and be connected with the bobbin, the one end that the amortization box was kept away from to the earphone cord is around establishing on the bobbin and extending to the outside setting of wire winding box, be equipped with adjustment mechanism in the wire winding box.

In the use process, the earphone wire with the redundant length is wound on the winding drum, so that the distance between the earphone head and the player is shortened, and the stethoscope effect caused by the friction between the earphone wire with the clothes is avoided.

In foretell earphone that can effectively prevent the stethoscope effect, adjustment mechanism includes the clamp plate of sliding connection in the wire winding box, fixedly connected with spring between the inside wall of clamp plate and wire winding box, fixedly connected with connecting rod on the clamp plate, the other end of connecting rod extends to wire winding box outer wall setting and fixedly connected with and draws the button.

Under the condition of not using, whole root earphone cord all is the winding on the bobbin, can prevent effectively that the earphone cord from taking place the winding, facilitates the use, when needs use, will draw the outside pulling of button, alright with the length in order to decide the earphone cord as required.
