Problems solved by technology

like figure 1 , figure 2 As shown, the existing traditional loudspeaker device has a large structural size, especially a large thickness. To achieve an ultra-thin and ultra-narrow size, the shape of the paper cone will become narrow and long, and the voice coil drive is concentrated at the middle point of the paper cone. When vibrating and sounding, the paper cone is prone to deformation and distortion, which cannot meet the requirements

Abstract

The invention discloses a loudspeaker as well as a television and a sound box adopting the loudspeaker and belongs to the technical field of design and manufacturing of accessories of household appliances. The loudspeaker whose outline dimension can be appropriately changed as needed as well as the television and the sound box adopting the loudspeaker for an ultrathin and ultra-narrow environment are provided. The loudspeaker comprises a magnet, a vibration system, a printed circuit board and a frame positioning rack, wherein the magnet comprises at least two strip magnetic blocks which are parallel to each other; each strip magnetic block is fixed through the frame positioning rack; and the printed circuit board arranged between the two adjacent strip magnetic blocks drives the vibration system to produce sound. Each of the television of the sound box includes the loudspeaker.

Description

technical field [0001] The invention relates to a loudspeaker and belongs to the technical field of design and manufacture of accessories of household electrical appliances. The present invention also relates to a TV installed with the loudspeaker and a sound box installed with the loudspeaker respectively. Background technique [0002] With the development of flat-panel TVs, the thickness and frame of TV sets are getting narrower and narrower; at the same time, external speakers are getting longer and narrower and thinner, matching them with ultra-thin and ultra-narrow strip speakers. Such as figure 1 , figure 2 As shown, the existing traditional loudspeaker device has a large structural size, especially a large thickness. To achieve an ultra-thin and ultra-narrow size, the shape of the paper cone will become narrow and long, and the voice coil drive is concentrated at the middle point of the paper cone. When vibrating and sounding, the paper cone is prone to deformatio...
