W-type loudspeaker

Abstract

The invention provides a W-type loudspeaker which refers that the cross section of the overall structure of the W-type loudspeaker is W-shaped. A W-shaped basin support is a basin-shaped support formed by an iron sheet via integral stamping. The periphery of the W-shaped basin support is provided with an external taper ring, an internal tape cover is arranged in the middle and an annular magnetic-conductive cavity is arranged at the lower end. The internal wall of the annular magnetic-conductive cavity is provided with an annular strong permanent magnet. A W-shaped paper cone is a basin-shaped voice diaphragm formed by paper material via integral processing. The periphery of the W-shaped paper cone is provided with a tape ring, a tape cover is arranged in the middle, and an annular installing slot is arranged at the lower end. A framework voice coil is adhered in the annular installing slot. The W-shaped structure is adopted so that an elastic wave plate of a common loudspeaker is enabled to be a taper paper cone which can stabilize the position of the voice coil and can also generate sound, power of the voice coil can be maximized, mass of a vibration component can be minimized, the performance index of the loudspeaker can be effectively enhanced, the improved magnetic circuit system is simple and low in total weight and thus advantages are obvious.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a W-shaped loudspeaker. Background technique [0002] The loudspeaker is an electro-acoustic device combined with a magnetic circuit system and a vibration system. It is an electro-acoustic device with a long history of development and relatively mature technology. At present, in the speaker technology, there are still continuous improvements in the magnetic circuit system and vibration system. A large number of new loudspeakers have emerged, for example, the published application number is "201120066480.3", and the patent document named "A Double Suspension Side Loudspeaker" has the same magnetic circuit system of the loudspeaker as the traditional loudspeaker, and its vibration system is the traditional The cone-shaped paper cone is changed into a flat plate, and the vibration of the traditional loudspeaker is changed from a single hanging side to a double hang...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of traditional loudspeakers and the existing "a double suspension side loudspeaker" technology, the present invention provides a W-shaped loudspeaker with improved magnetic circuit system and vibration system, which not only improves the complex magnetic circuit system of the existing loudspeaker , cumbersome shortcomings, and absorb the advantages of the cone-shaped paper cone and double hanging edge, it adopts W-shaped structure, which can make the elastic plate of the ordinary speaker become a cone-shaped paper cone that not only stabilizes the position of the voice coil, but also can produce sound. The voice coil power is maximized, the mass of the vibrating parts is minimized, and the performance index of the speaker is effectively improved
