Description

Technical Field

[0001] The utility model relates to the field of vibration membranes, and more specifically, to a vibration membrane and a loudspeaker. Background Art

[0002] The vibration membrane is one of the important components of various speakers such as earphones, headphones, and microphones. The vibration membrane includes a dome and a folding ring. The vibration membrane is usually a single-layer vibration membrane formed of a single material. When a speaker makes a sound, there are usually high and low frequencies. The higher the resonant frequency of the vibration membrane, the higher the corresponding high frequency that the vibration membrane can produce. The lower the resonant frequency of the vibration membrane, the lower the corresponding low frequency that the vibration membrane can produce.

[0003] Some existing diaphragms are simply placed within the speaker's mounting area, such as in headphones. There's no secure assembly between the diaphragm and the headphone housing, which consists of a main body and a cover. If the cover becomes damaged and falls off, the diaphragm could fall out or even become damaged, reducing the product's performance. Therefore, to address this issue, we propose a diaphragm and speaker. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a vibration membrane and a loudspeaker, which adopt the following technical solutions:

[0005] A vibration membrane includes a vibration membrane body, a mounting ring is provided on the outer fixed sleeve of the vibration membrane body, a rubber ring is provided on the side wall fixed sleeve of the mounting ring, a plurality of movable grooves distributed in a circular array are opened on the side wall of the mounting ring, and a positioning assembly is provided in the movable groove, and a protective assembly is provided between the vibration membrane body and the mounting ring.

[0006] By adopting the above technical solution, the staff places the vibration diaphragm body inside the existing speaker shell. A mounting ring is provided on the outside of the vibration diaphragm body, and a rubber pad is provided on the outside of the mounting ring, which is beneficial to increase the friction between the mounting ring and the inner wall of the speaker shell. A positioning component is provided on the outside of the mounting ring, which can play a role in positioning and fixing the mounting ring, and then play a role in positioning and fixing the vibration diaphragm body, which is beneficial to maintaining the stability of the installation of the vibration diaphragm body. A protective component is provided between the vibration diaphragm body and the mounting ring, which can play a role in protecting the vibration diaphragm body, which is beneficial to reduce the degree of damage to the vibration diaphragm body.

[0007] Furthermore, the positioning assembly includes a positioning rod slidably installed in the movable groove, and a spring is fixedly connected between the end of the positioning rod close to the vibration membrane body and the inner wall of the side opposite to the movable groove of the same group, and the end of the positioning rod away from the vibration membrane body is chamfered.

[0008] By adopting the above technical solution, the staff places the vibration membrane body inside the existing speaker shell. Due to the action of the inner wall of the speaker body, the positioning rod slides into the same group of movable grooves, and the positioning rod pushes the same group of springs to contract. When the vibration membrane body and the mounting ring are placed in the corresponding positions, the positioning rod returns to its original position under the elastic force of the same group of springs, and the end of the positioning rod contacts the inner wall of the speaker shell. The positioning rod is made of rubber material, which is conducive to increasing the friction between the positioning rod and the inner wall of the speaker, and thus is conducive to maintaining the stability of the placement of the vibration membrane body.

[0009] Furthermore, two symmetrically distributed sliding blocks are fixedly mounted on the side wall of one end of the positioning rod close to the vibration membrane body, and the inner wall of the movable groove is provided with a sliding groove matching the sliding blocks of the same group.

[0010] By adopting the above technical solution, when the positioning rod slides in the movable groove, the positioning rod slides with the slider in the same group of sliding grooves, and the cooperation between the slider and the sliding groove is conducive to maintaining the sliding stability of the positioning rod and helps to prevent the positioning rod from leaving the movable groove.

[0011] Furthermore, the protective assembly includes a connecting block arranged above the vibration membrane body, and a plurality of protective rods distributed in a circular array are fixedly installed on the side wall of the connecting block. An insert block is fixedly installed on one end of the protective rod away from the connecting block, and a slot matching the insert block is provided at the top of the mounting ring.

[0012] By adopting the above technical solution, the outer side of the vibration membrane body plays a role in protecting the vibration membrane body through the cooperation of the connecting block and the protective rod, which helps to reduce the damage to the vibration membrane body. The protective rod is positioned by the slot opened by the plug block and the top of the mounting ring, which can play the role of positioning and fixing the protective rod and is convenient for the staff to disassemble it later.

[0013] Furthermore, the inner wall of the bottom end of the slot is fixedly mounted with a limiting rod, and the bottom end of the insert block is provided with a limiting hole matching the limiting rod of the same group.

[0014] By adopting the above technical solution, a limit rod is provided in the slot. When the insert slides into the same group of slots, the limit rod engages with the limit hole opened at the bottom end of the insert, and the limit rod is made of rubber material, which is conducive to improving the stability of the protection rod installation.

[0015] Furthermore, a stabilizing rod is fixedly installed between two adjacent protective rods.

[0016] By adopting the above technical solution, the stabilizing rod is set between two adjacent protective rods, which plays a role in strengthening and stabilizing the protective rods, and is beneficial to improving the protective effect of the equipment.

[0017] Furthermore, a first positioning ring and a second positioning ring are fixedly mounted on the inner side and the inner wall of the top end of the vibration membrane body respectively.

[0018] By adopting the above technical solution, the interior of the vibration membrane body plays a positioning role through the arrangement of the first positioning ring and the second positioning ring, which is beneficial to improving the installation efficiency of the vibration membrane body.

[0019] A loudspeaker comprises the above-mentioned vibration membrane.

[0020] In summary, the present invention has the following beneficial technical effects:

[0021] (1) In the present invention, the positioning assembly is provided to position and fix the diaphragm body, and a rubber pad is provided on the outside of the mounting ring, which is beneficial to increase the friction between the mounting ring and the inner wall of the speaker housing, thereby helping to maintain the stability of the installation of the diaphragm body.
