Abstract
An earphone core having an anti-noise function comprises a conductor, and is characterized in that a TPE (Thermoplastic Elastomer) sheath layer (2) is wrapped out of the conductor (1), and the TPE sheath layer (2) employs an anti-noise TPE material. The earphone core wraps the TPE sheath layer out of the conductor so as to reduce noise caused by the friction of wires with other objects, thereby improving audio-video quality in the process of using an earphone.
Description
Technical field
The utility model relates to electric wire, is a kind of earphone cord with anti-noise function specifically.
Background technology
General earphone cord skin-friction coefficient is bigger, can produce friction noise when in use contacting with other object, imports in the ear through earphone, has seriously reduced acoustical quality, influences audiovisual, and is more obvious in particular for this problem on the earphone of ear type.
Summary of the invention
The purpose of the utility model provides a kind of earphone cord with opposing friction noise function.
Said earphone cord with anti-noise function comprises conductor, it is characterized in that: outside conductor, wrap the TPE restrictive coating.
Said TPE restrictive coating is an anti-noise TPE material.
Said conductor is one of following several kinds: enamel-cover twisted wire, bare copper stranded wire, zinc-plated twisted wire.
The utility model reduces the noise that the friction of wire rod and other object is produced through outside conductor, wrapping the TPE restrictive coating; Improve the view quality of people in using the earphone process; Described TPE restrictive coating is an anti-noise TPE material, makes people that more better choice arranged when choosing earphone cord.
Description of drawings
Fig. 1 is the utility model cross section structure sketch map.
Among the figure: 1-conductor, 2-TPE restrictive coating.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: the earphone cord with anti-noise function as shown in fig. 1 wraps TPE restrictive coating 2 outside conductor 1.
Said TPE restrictive coating 2 is an anti-noise TPE material.
Said conductor is one of following several kinds: enamel-cover twisted wire, bare copper stranded wire, zinc-plated twisted wire.
The utility model reduces the noise that the friction of wire rod and other object is produced through outside conductor, wrapping the TPE restrictive coating; Improve the view quality of people in using the earphone process; Described TPE restrictive coating is an anti-noise TPE material, makes people that more better choice arranged when choosing earphone cord.
Claims (3)
