Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker drum paper, in particular to a loudspeaker drum paper with a glass acoustic diaphragm. Background Art

[0002] As people's living standards continue to improve, electronic products are becoming more and more popular in thousands of households. The speakers installed on electronic products are developing in the direction of thinner and lighter, especially on small speakers, ultra-thin LCD TVs, laptops and other electrical appliances. The quality of the speakers directly affects the sales volume of electronic products. The drum paper is the main sound-generating component of the speaker. When the speaker is working, the voice coil will generate strong vibrations in the magnetic field after receiving the audio signal. Since the voice coil is fixed on the drum paper, the vibration of the voice coil also drives the vibration of the drum paper, and the vibration of the drum paper further forces the air to vibrate, thereby making a sound. Therefore, the sound quality of the drum paper determines the quality of the speaker. Since most of the existing drum papers are single-piece cone structures made of various materials, they occupy a large space and have poor structural strength, and cannot produce a good range of sound.

[0005] Preferably, central axes of the hemispherical convex surface, the glass diaphragm and the suspension edge coincide with each other.

[0006] Preferably, the inner wall of the glass diaphragm is provided with a light-storage coating, and the light-storage coating is in a circular shape and is provided around the circumference of the glass diaphragm.

[0007] Preferably, the hanging edge is in an outwardly convex arch structure, and a UV adhesive layer is provided at the connection between the hanging edge and the glass diaphragm.

[0016] The utility model is described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 to Figure 2 As shown, the utility model is a speaker drum paper with a glass acoustic diaphragm, comprising a glass diaphragm 1 and a suspension edge 2 arranged on the glass diaphragm 1, wherein the suspension edge 2 is arranged around the circumference of the glass diaphragm 1, and the center of the glass diaphragm 1 protrudes upward to form a hemispherical convex surface 11, and both sides of the hemispherical convex surface 11 extend outward to form connecting arms 12, and the hemispherical convex surface 11 is integrally formed with the glass diaphragm 1 through the connecting arms 12.

[0018] When the present application is used in conjunction with an external voice coil, since the center of the glass diaphragm 1 bulges upward to form a hemispherical convex surface 11, the hemispherical convex surface 11 is integrally formed with the glass diaphragm 1 through a connecting arm 12, thereby facilitating the installation of the voice coil on the lower surface of the hemispherical convex surface 11. Preferably, the voice coil and the lower surface of the hemispherical convex surface 11 are bonded and fixed with glue, without the need for additional installation parts, and the space utilization rate is high. After the voice coil is connected to the audio signal, an up-and-down force is formed in the magnetic field, thereby driving the entire glass diaphragm 1 to vibrate up and down to produce sound, and the glass diaphragm 1 is made of reinforced lightweight glass with advanced cutting technology to prevent the glass from breaking, and then through precision molding, it better meets the processing requirements of the shape structure required by the glass diaphragm 1, so that the hardness and toughness of the glass diaphragm 1 are optimized, and a suitable damping effect is produced. At the same time, it also has the characteristics of high structural strength, low density, fast sound speed, high electroacoustic conversion efficiency, good sound quality and timbre. The high structural strength can reduce the split vibration, the deformation is small at low frequency, and a wide sound range is developed, which greatly improves the sound effect, the sound speed is fast, and the damping is moderate and the distortion is low. In addition, glass is an environmentally friendly material that can be recycled and reused, which effectively reduces environmental pollution. Glass also has the characteristics of high strength, impact resistance, waterproof and anti-fouling, high hardness, pressure resistance and scratch resistance, and good heat dissipation. The utility model is easy to process and shape, meets the product requirements of lightweight and compact structure, ensures good structural strength and wide sound range, and improves the quality of sound effect.

[0019] In this embodiment, the central axes of the hemispherical convex surface 11, the glass diaphragm 1, and the hanging edge 2 coincide with each other. Specifically, the hemispherical convex surface 11 and the glass diaphragm 1 are integrally formed, and the hanging edge 2 is arranged around the circumference of the glass diaphragm 1. The central axes of the hemispherical convex surface 11, the glass diaphragm 1, and the hanging edge 2 coincide with each other, ensuring the accuracy and coaxiality of the positions of the components, achieving accurate alignment among the hemispherical convex surface 11, the glass diaphragm 1, and the hanging edge 2, and improving the overall structural strength and assembly yield of the drum paper.

[0020] The inner wall of the glass diaphragm 1 of this embodiment is provided with a light-storage coating 13, which is in a circular shape and is provided around the circumference of the glass diaphragm 1. Specifically, the light-storage coating 13 can be provided in different patterns to play a decorative and aesthetic role. By providing the light-storage coating 13 on the inner wall of the glass diaphragm 1, it is easier to find and locate the drum paper in a dim external environment, thereby facilitating the location of the speaker and reducing accidental bumps. The light-storage coating 13 is also called phosphorescent paint, which is a paint that can emit fluorescence in the dark. The paint contains fluorescent substances, which can not only emit light when exposed to light, but also store light, and can still emit fluorescence when the lighting disappears. This is a paint prepared by a yellow-green zinc sulfide phosphor and volatile paints such as nitro lacquer, and trace amounts of heavy metals such as copper, manganese, bismuth, and lead are added as activators. This is a prior art and will not be repeated.

[0021] The hanging edge 2 of this embodiment is an outwardly convex arch structure, and a UV adhesive layer 3 is provided at the connection between the hanging edge 2 and the glass diaphragm 1. Specifically, a UV adhesive layer 3 is provided at the connection between the hanging edge 2 and the glass diaphragm 1 to facilitate molding and curing, reduce processing time, and improve the manufacturing capacity and yield rate of drum paper.

[0022] The suspension edge 2 of this embodiment is made of rubber material. Specifically, the suspension edge 2 is made of TPE, TPU or RB material and is made by hot pressing, which ensures the convenience of production of the suspension edge 2, reduces production costs, and saves resources. In addition, because rubber has a certain viscosity, the suspension edge 2 can be more firmly formed on the edge of the glass diaphragm 1 through the UV bonding layer 3, and the connection is stable and reliable.

[0023] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
