Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention,

referring to fig. 1-2 of the drawings,

the ultrathin loudspeaker in the embodiment of the utility model is usually arranged in a loudspeaker box, the volume of the loudspeaker is reduced, so that the aim of reducing the volume of the loudspeaker box is fulfilled, the whole loudspeaker is more attractive, and the ultrathin loudspeaker is particularly suitable for places with relatively narrow space, of course, the ultrathin loudspeaker is not only suitable for the loudspeaker box, for example, but also suitable for automobiles, so that the application range of the ultrathin loudspeaker is not limited,

the ultrathin loudspeaker specifically comprises a cone 1 and a basin frame 2 which is installed in a matched mode, wherein the cone 1 is composed of a suspension edge 11, a folding ring 12 and a vibrating diaphragm 13 which are sequentially connected from outside to inside, the suspension edge 11 is connected with the basin frame 2, a magnetic circuit component 3, a voice coil 4, a centering support piece 5 and a fixing frame 6 are installed in the basin frame 2, the magnetic circuit component 3 comprises a T iron, a magnet 32 is sleeved on the T iron, a washer 33 is arranged on the magnet 32, in the embodiment of the utility model, the magnet 32 is a neodymium iron boron magnet 32 or a ferrite magnet 32, the voice coil 4 comprises a support (not shown) and a coil (not shown), the coil is wound on the inner side of the support, one end of the support is connected with the cone 1, the other end of the support extends downwards to the periphery of the T iron, the inner periphery of the centering support piece 5 is connected with the outer periphery of the support, the outer periphery of the centering support piece 5 is connected with the bottom of the fixing frame 6, the top of the fixing frame 6 is connected with the vibrating diaphragm 13, and in the embodiment of the utility model, the shaping support, the fixing frame 6 and the vibrating diaphragm 13 are fixed by gluing.

The magnetic circuit component 3 is innovatively arranged in the basin frame 2, the volume of the loudspeaker is reduced substantially under the condition of not influencing the tone quality, so that a sound box with smaller volume is manufactured conveniently, the whole body is more attractive, the requirement of people is met, when the coil is electrified to generate a magnetic field, an interaction force is generated with the magnetic circuit component 3, the support is driven to move up and down along the T iron direction, and the sound basin 1 is driven to vibrate to push the surrounding air to vibrate to generate sound;

because the periphery of the centering support piece 5 is not connected with the basin frame 2, but is fixedly connected with the sound basin 1 through the fixing frame 6, the effect of fixing the voice coil 4 is achieved, the voice coil is not limited by action amplitude, but acts along with the action of the voice coil 4, namely the voice coil 4 is not limited by pulling of the centering support piece 5, so that the stroke can be increased under the condition of original power, and the effect of optimizing bass is achieved.

In the embodiment of the utility model, the voice cone 1 is provided with the dustproof cap 7, so that dust can be prevented from entering the magnetic circuit component 3 and influencing the sensitivity of the voice coil 4.
