A kind of voice coil loudspeaker voice coil, described voice coil loudspeaker voice coil is formed by voice coil line coiling, and described voice coil line is above-mentioned voice coil line.
For solving above-mentioned 3rd technical problem, the technical solution of the utility model is:
A kind of loud speaker, involving vibrations system and magnetic circuit system, described vibrational system comprises the vibrating diaphragm and voice coil loudspeaker voice coil that combine, and described voice coil loudspeaker voice coil is above-mentioned voice coil loudspeaker voice coil.
After have employed technique scheme, the beneficial effects of the utility model are:
Because the utility model voice coil line also comprises a layer graphene, graphene layer is looped around the periphery of core.Graphene is at present thin, the hardest nano material, and is the minimum material of current resistivity, has the features such as outstanding electronics is transportability, high tenacity, high strength and high-termal conductivity.Based on the above-mentioned advantage of Graphene, voice coil line tool compared with traditional enamelled wire that the utility model includes graphene layer has the following advantages:
One, firmer antibody Monoclonal, not easily breaks;
The voice coil loudspeaker voice coil of two, coiling similar resistance, the voice coil loudspeaker voice coil quality of the utility model voice coil line coiling is lighter, effectively can promote the sensitivity of loud speaker;
Three, the voice coil loudspeaker voice coil power loss that goes out of coiling is lower;
Four, the voice coil loudspeaker voice coil perfect heat-dissipating of coiling, when loud speaker works long hours or operating power is higher, effectively reduces the risk that voice coil loudspeaker voice coil burns out.
Because the utility model voice coil loudspeaker voice coil is formed by above-mentioned voice coil line coiling, then the utility model voice coil loudspeaker voice coil has the not easy fracture that goes between compared with traditional voice coil, good heat conductivity, and power is little, and quality is light, is more conducive to improving the advantages such as loudspeaker sensitivity.
Voice coil loudspeaker voice coil due to the utility model loud speaker is above-mentioned voice coil loudspeaker voice coil, then the utility model loud speaker has quality gently, low in energy consumption, highly sensitive; And voice coil loudspeaker voice coil to burn out probability low, the advantages such as long service life.
In sum, the utility model voice coil line and to solve voice coil loudspeaker voice coil quality in prior art with the voice coil loudspeaker voice coil of this voice coil line coiling and the loud speaker that is provided with this voice coil loudspeaker voice coil large, the technical problem such as easily damaged, the utility model voice coil line and with the voice coil loudspeaker voice coil of this voice coil line coiling and be provided with this voice coil loudspeaker voice coil loud speaker in voice coil loudspeaker voice coil quality light, low in energy consumption, not easily break, not easy burn-out, effectively improve the sensitivity of loud speaker, extend the useful life of loud speaker.
