Description

Technical Field

[0001] The utility model relates to the technical field of drum paper, in particular to a loudspeaker drum paper with high structural strength. Background Art

[0002] A loudspeaker is a commonly used modern electroacoustic component that converts electrical signals into sounds. Currently, most loudspeakers on the market use drum paper. When the voice coil is connected to an audio signal, it will generate strong vibrations in the magnetic field. The voice coil is fixed on the drum paper. The vibration of the voice coil also drives the vibration of the drum paper, and then the vibration of the drum paper forces the air to vibrate and form sound. As people's requirements for sound quality continue to increase, drum papers of various materials have also appeared one after another. Due to the different materials of drum papers, the sound quality effects are different. Existing drum papers are generally made of pulp material. Drum paper made of pulp material is easily softened after absorbing moisture in the air. The structural strength will also change with the temperature and humidity of the environment, resulting in poor structural stability, reduced performance, and affecting the sound quality effect.

[0018] The utility model is described in detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, a speaker drum paper with high structural strength of the utility model comprises a body 1 and a hanging edge 2 connected to the body 1, wherein the hanging edge 2 is arranged around the circumference of the body 1, and the body 1 comprises a wear-resistant layer 11, a base layer 12 and a reinforcing layer 13 arranged in sequence, wherein the lower surface of the wear-resistant layer 11 is bonded to the upper surface of the base layer 12, and the lower surface of the base layer 12 is bonded to the upper surface of the reinforcing layer 13, the wear-resistant layer 11 faces the outer wall of the body 1, and the reinforcing layer 13 faces the inner wall of the body 1.

[0020] The hanging edge 2 is arranged around the circumference of the carcass 1, and the wear-resistant layer 11 and the reinforcing layer 13 are respectively formed on the upper surface and the lower surface of the base layer 12 by gluing, and the wear-resistant layer 11 faces the outer wall of the carcass 1, and the reinforcing layer 13 faces the inner wall of the carcass 1. The wear-resistant layer 11 is used to protect the outer wall of the carcass 1 from scratches and wear, ensuring the long-term normal use of the carcass 1 and a long service life. The reinforcing layer 13 is used to reinforce the structure of the inner wall of the carcass 1, thereby improving the overall structural strength of the carcass 1, and is not prone to bending and deformation. It has the advantages of light volume, scratch resistance, wear resistance and stable structure. The utility model has a compact structure and light volume, good structural strength and performance, and improves the sound quality effect.

[0021] The reinforcement layer 13 of this embodiment includes a first rib 131 and a second rib 132 that are interlaced and woven, wherein the first rib 131 is made of carbon fiber material, and the second rib 132 is made of glass fiber material. Specifically, the first rib 131 is made of carbon fiber material, and the first rib 131 has a fiber-like appearance. The first rib 131 and the second rib 132 are interlaced and woven to form the reinforcement layer 13, which can ensure that the weight of the reinforcement layer 13 is light, thereby effectively reducing the overall weight of the drum paper, and can ensure that the drum paper has good rigidity and strength, and can bear and support the voice coil of the speaker when in use, so as to avoid the drum paper and the voice coil of the speaker being separated and used improperly, so that the drum paper maintains good sound quality and a suitable vibration frequency.

[0022] The carcass 1 of this embodiment is provided with a support bar 3, which is protruded from the surface of the carcass 1. There are a plurality of support bars 3, and the plurality of support bars 3 are arranged around the circumference of the carcass 1, so that the plurality of support bars 3 enclose a support space. Specifically, the plurality of support bars 3 are arranged around the circumference of the carcass 1, so that the plurality of support bars 3 enclose an enclosed support space, and the support space is used to support the entire carcass 1, thereby further improving the structural strength of the carcass 1 and reducing the possibility of structural damage caused by external influences.

[0023] In this embodiment, a connecting rib 4 is provided between two adjacent support bars 3. Specifically, the connecting rib 4 connects two adjacent support bars 3 in a transverse direction, and the connection is stable and reliable, so as to avoid positional deviation of the plurality of support bars 3, further ensure that the plurality of support bars 3 are firmly supported on the periphery of the carcass 1, improve the structural strength between the plurality of support bars 3, and extend the service life of the drum paper.
