Description

Structure of ultrathin loudspeaker

Technical Field

The utility model relates to the technical field of loudspeakers, in particular to an ultrathin loudspeaker structure.

Background

With the continuous development of society, great importance is attached to the enjoyment of mental vision by the big families, for example, listening to songs, enjoying music, singing karaoke, and relaxing the mood, the enjoyment becomes a normal state, the area of the living room or bedroom of the ordinary family is between 15 and 25 square meters, the power of the sound box does not need to be very large, but the required volume is relatively small, the tone quality is relatively good, especially, a sound box with creative and small artistic modeling is popular at present, such as a sound box with an artistic sphere, and a sound box with a slightly opened book shape, such as a book stand, the loudspeaker is ultra-thin, the structure is more reasonable, therefore, people are all striving to research high-quality ultra-thin loudspeakers, the existing patent publication is CN 212064356U, the name is 'ultra-thin subwoofer', namely the ultra-thin loudspeaker, and a planar cone is adopted, the height of the speaker is reduced, but the plane paper cone is inferior to the high sound transmission, so the research of the ultra-thin speaker needs to be ultra-thin, and the sound range of the high and low sound range has enough width, which is the direction of the innovative design of the inventor.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the present invention is to provide an ultra-thin speaker structure, which is ultra-thin and has a wide enough sound range for sound transmission, in order to overcome the above-mentioned shortcomings of the prior art.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: a structure of an ultra-thin speaker is disclosed,

including basin frame, end magnetic pole piece, magnet steel, go up magnetic pole piece, antipole magnet steel, voice coil loudspeaker voice coil, drum paper, spring board and dustproof cap, its characterized in that: the cone-shaped drum paper is cone-shaped, the upper circular edge of the cone is placed on the opening circular edge of the basin frame, one surface of the spring plate is connected with a step in the basin frame, and a dustproof cap is arranged at the upper opening of the voice coil.

The basin stand is divided into three steps of high, middle and low, the spring plate is placed on the middle step, and the upper round edge of the drum paper is placed on the high step.

The voice coil is close to the periphery of the cylinder, but can move up and down without friction.

And a copper enameled coil is wound on the periphery of part of the voice coil according to the conventional method, and two ends of the enameled coil are connected with the wiring terminals on the basin stand.

The utility model has the beneficial effects that: the structure is simple, and the assembly is convenient and quick; the height of the 2-4 inch loudspeaker can be 20-40 mm, the range of sound still has enough width, and the tone quality is guaranteed.

Drawings

Fig. 1 is a schematic structural cross-sectional view of an ultra-thin speaker according to the present invention.

Detailed Description

The utility model is described in further detail below in an embodiment with reference to the drawings.

As shown in the figure, the structure of ultra-thin speaker of this embodiment, including basin frame 1, end magnetic pole piece 2, magnet steel 3, go up magnetic pole piece 4, antipole magnet steel 5, voice coil loudspeaker voice coil 6, drum paper 7, spring board 8 and dust cap 9, its characterized in that: the improved bathtub comprises a bathtub frame 1 and is characterized in that a bottom magnetic pole piece 2 is arranged at the bottom of the inner center of the bathtub frame 1, magnetic steel 3 is arranged on the bottom magnetic pole piece 2, an upper magnetic pole piece 4 is arranged on the magnetic steel 3, antipole magnetic steel 5 is arranged on the upper magnetic pole piece 4, the diameters of the bottom magnetic pole piece 2, the magnetic steel 3, the upper magnetic pole piece 4 and the antipole magnetic steel 5 are the same, a cylinder is formed, a voice coil 6 is sleeved on the periphery of the cylinder, the outer lower part of the voice coil 6 is connected with a bottom circular edge of drum paper 7 and an inner circular edge of a spring plate 8, the drum paper 7 is in a cone shape, the upper circular edge of the cone is placed on an opening circular edge of the bathtub frame 1, one surface of the spring plate 9 is connected with a step of an inner platform of the bathtub frame 1, and a dustproof cap 9 is arranged at the upper opening of the voice coil 6.

The basin stand 1 is internally divided into a high step, a middle step and a low step, the middle step is used for placing the spring plate 8, and the high step is used for placing the drum paper 7.

The voice coil 6 is arranged to abut against the outer circumference of the cylinder but can move up and down without friction.

Copper enameled coils are wound on the periphery of the voice coil 6 according to the conventional method, and two ends of each enameled coil are connected with wiring terminals (not shown) on the basin frame 1.
