Embodiment 1

[0023] figure 1 A sectional view of a loudspeaker unit provided by an embodiment of the present invention.

[0024] Such as figure 1 As shown, the speaker unit includes a magnetic cover 3, a magnet 4 and a washer 5 arranged in sequence, and the centers of the magnetic cover 3, magnet 4 and washer 5 are respectively provided with openings of the same shape and size; the speaker unit is provided with a The fixed column 1, the shape of the fixed column 1 matches the opening; the magnetic cover 3, the magnet 4 and the washer 5 are set on the fixed column 1, and are concentrically fixed together by the fixed column 1.

[0025] Holes are made in the center of the magnetic cover 3, magnet 4, and washer 5 of the speaker unit, and the fixing column 1 adapted to the shape of the opening is used to penetrate the three together. On the premise of ensuring the concentricity of the three, the All three are firmly held together. The loudspeaker unit with this structural design can ensure ...

Embodiment 2

[0032] figure 2 A sectional view of a loudspeaker unit provided by another embodiment of the present invention, different from Embodiment 1, the fixing column 1 is a metal rivet, and the magnetic cover 3, the magnet 4 and the washer 5 are concentrically fixed together by the riveting process .

[0033] The invention also discloses a method for making a loudspeaker unit. The loudspeaker unit includes a magnetic cover, a magnet and a washer arranged in sequence. The opening of the loudspeaker unit is provided with a fixed column whose shape matches the opening; the magnetic cover, magnet and washer are placed on the fixed column, and the three are concentrically fixed together through the fixed column.

[0034] Holes are made in the center of the magnetic cover, magnet and washer of the loudspeaker unit, and the fixing columns that match the shape of the opening are used to connect the three together. On the premise of ensuring the concentricity of the three, the three are fir...

Abstract

The invention discloses a single loudspeaker and a production method of the single loudspeaker. The single loudspeaker comprises a magnetic cover, a magnet and a washer which are arranged in sequence. The centers of the magnetic cover, the magnet and the washer are provided with holes. The holes are consistent in shape and size. A fixed column is arranged in the single loudspeaker. The shape of the fixed column is matched with the shapes of the holes. The magnetic cover, the magnet and the washer sleeve the fixed column and are concentrically fixed together by the fixed column. Through arrangement of the holes at the centers of the magnetic cover, the magnet and the washer of the single loudspeaker, the magnetic cover, the magnet and the washer are brought together in a penetrating manner by the fixed column which is matched with the holes in shape. The magnetic cover, the magnet and the washer are firmly fixed together on the premise of ensuring the concentricity of the magnetic cover, the magnet and the washer. According to the single loudspeaker with such a structural design, distribution of the magnetic field generated by a magnetic circuit system is uniform, a high-quality sound effect is provided, the magnetic circuit system is fixed through adoption of the fixed column, therefore, the strength is relatively high, the reliability is high, and the service life of the product can be improved.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker unit and a method for manufacturing the loudspeaker unit. Background technique [0002] The speaker unit includes a vibration system and a magnetic circuit system. The vibration system includes a voice coil and a diaphragm. The magnetic circuit system usually includes a washer, a magnet, a magnetic cover, and a basin frame. The sounding principle of the loudspeaker is to input the audio current into the voice coil of the single loudspeaker, so that the voice coil is driven by the magnetic field to drive the diaphragm to vibrate and produce sound. High, that is, the requirements for the manufacturing precision of the magnetic circuit system are very high. In the current loudspeaker unit, the fixing between the magnetic cover, the magnet and the washer is usually realized by glue bonding. [0003] However, due to size differences among the magnetic cover, magne...
