Description

Bass radiation vibrating diaphragm

Technical Field

The utility model relates to a sound membrane especially relates to a bass radiation vibrating diaphragm.

Background

The sound film, i.e. the diaphragm, also commonly called "cone", is the core component of the speaker, and is the key for the speaker to convert the level signal into the audio signal. When the loudspeaker inputs an electric signal, the electric signal drives the vibrating diaphragm to vibrate through the principle of electromagnetic effect, piezoelectric effect or electrostatic effect, so that an audio signal is emitted. Among the many diaphragm products is a bass-radiating diaphragm, often referred to as a passive plate, which is typically constructed by bonding a soft suspension edge to a metal plate, primarily to reinforce the bass-tone section of the speaker.

The existing bass radiation diaphragm product in the market is usually a complete passive plate product formed by molding a suspension edge or a sound film main body part and then bonding a metal plate on the suspension edge or the sound film main body part. The passive plate processed in this way is often unstable in structural strength, and the metal plate is easy to loosen and the like. And the production and processing in multiple steps not only reduces the production efficiency, but also is easy to have accidents in the production process, and causes adverse effects on the quality of products.

SUMMERY OF THE UTILITY MODEL

In view of the foregoing, it is desirable to provide a bass-radiation diaphragm.

The utility model provides a bass radiation vibrating diaphragm, includes vibrating diaphragm main part and metal sheet, vibrating diaphragm main part integrated into one piece includes the central part from inside to outside in proper order, rolls over the ring and hangs outside the limit. The central part is internally provided with an accommodating cavity, and the metal plate is embedded in the accommodating cavity. The section of the corrugated ring is in a wave-shaped design.

Furthermore, the folding ring is of an annular design and consists of a plurality of sections of folding ring sections. The cross section of each folded ring section is in a wave-shaped design, and the directions of wave crests and wave troughs of any two adjacent folded ring sections are different.

Furthermore, the bottom of the accommodating cavity is also provided with a plurality of heat dissipation through holes which are uniformly distributed. The plurality of heat dissipation through holes are different in size.

Furthermore, a plurality of mounting through holes are formed in the edge outside the suspension edge. The main part of the vibrating diaphragm is rounded.

To sum up, the utility model relates to a bass radiation vibrating diaphragm's beneficial effect lies in: by designing the integrally formed vibrating diaphragm main body part and embedding and wrapping the metal plate in the vibrating diaphragm main body part, the metal plate is more firmly and stably assembled, the quality of a product is improved, the process flow can be simplified by the integrated processing and forming, and the production efficiency is improved; the corrugated curved surface folded ring in the multi-section design can support the center part and also has certain amplification and improvement on the acoustic effect of the vibrating diaphragm; the heat dissipation through holes in the main body part of the vibrating diaphragm are more convenient for dissipating heat generated in the vibrating process of the vibrating diaphragm, so that adverse effects on the vibrating diaphragm caused by high temperature are avoided; the utility model discloses the practicality is strong, has stronger popularization meaning.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to fig. 3, the utility model provides a bass radiation diaphragm 100, including diaphragm main part 10 and metal sheet 20, diaphragm main part 10 integrated into one piece includes central part 11, book ring 12 and hangs the limit in proper order from inside to outside 13. An accommodating cavity (not shown) is arranged in the central part 11, and the metal plate 20 is embedded in the accommodating cavity. The section of the corrugated ring 12 is in a wave-shaped design. The integrally formed diaphragm body portion 10 supports the acoustic effect of the low frequency band more stably. The metal plate 20 embedded and wrapped in the accommodating cavity is more stable and firm, and the problems of loosening and the like can be avoided. The corrugated design of the folding rings 12 provides better support for the central part 11.

The folding ring 12 is of an annular design and is composed of a plurality of folding ring segments 121. The cross section of each bending ring segment 121 is designed in a wave shape, and the directions of the wave crests and the wave troughs of any two adjacent bending ring segments 121 are different. The multi-section connection type folding rings 12 enable the diaphragm to generate richer and more changeable hearing, and further optimize the acoustic effect of the diaphragm.

The bottom of the accommodating cavity is also provided with a plurality of heat dissipation through holes 111, and the heat dissipation through holes 111 are uniformly distributed. The plurality of heat dissipation through holes 111 are provided with different sizes. The heat dissipation through holes 111 are beneficial to heat exchange between the passive plate and the outside, so that heat generated in the vibration process of the passive plate can be dissipated more quickly, and the influence of high temperature on the service life of the passive plate is avoided.
