A small size and easy to install diaphragm

Abstract

This utility model discloses a small-sized, easy-to-install diaphragm, belonging to the field of diaphragm technology. It includes a base layer, a diaphragm body on top of the base layer, an adsorption layer on top of the diaphragm body, an extension strip connected to the outside of the adsorption layer, a thin film inside the base layer, and the diaphragm body adsorbed on top of the thin film. A tear groove is formed on the top of the base layer. By setting the adsorption layer and the extension strip, this utility model allows for stable and controllable pulling of the adsorption layer during use, enabling the diaphragm body to gradually adhere to the product surface from one end to the other.

Description

Technical Field

[0001] This utility model relates to the field of diaphragm technology, specifically a small-sized diaphragm that is easy to install. Background Technology

[0002] In many technical fields such as optical devices, precision sensors, electronic product display modules and miniature speakers, small-sized functional films are increasingly widely used. These films are usually installed on specific cavities, openings or frames by direct pasting or adsorption through their adhesive backing or by using the principle of electrostatic adsorption, so as to achieve functions such as light transmission, sound transmission, protection and pressure balance. Small-sized diaphragms are often installed by direct gluing or adsorption, but problems such as air bubbles, misalignment, and difficulty in positioning can easily occur during the installation process. Especially in applications with high precision requirements, the installation efficiency of traditional diaphragms is low and the success rate is not high, which affects the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a small-sized diaphragm that is easy to install, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a small-sized, easy-to-install diaphragm, comprising a base layer, a diaphragm body disposed above the base layer, an adsorption layer adsorbed above the diaphragm body, an extension strip connected to the outside of the adsorption layer, a thin film disposed inside the base layer, the diaphragm body adsorbed above the thin film, a tear groove being formed above the base layer, and the base layer being connected to the thin film through the tear groove.

[0005] As a further preferred embodiment of this technical solution, the adsorption layer is made of silicone.

[0006] As a further preferred embodiment of this technical solution, the extension strip is made of PET material.

[0007] As a further preferred embodiment of this technical solution, the film is a release film, and its surface is treated with an anti-stick coating.

[0008] As a further preferred embodiment of this technical solution, the tear groove is arranged in a ring shape.

[0009] This utility model provides a small-sized diaphragm that is easy to install, and has the following beneficial effects: (1) By setting an adsorption layer and an extension strip, this utility model allows for a smooth and controllable pulling of the adsorption layer during use, enabling the membrane body to gradually adhere to the product surface from one end to the other. This process achieves initial positioning and slow adsorption of the membrane, effectively eliminating internal air and significantly reducing the generation of air bubbles. At the same time, the extension strip provides a good control point for operating force, preventing overall displacement or twisting caused by improper adhesion at one time, greatly improving the accuracy and success rate of installation, and is especially suitable for surface protection of micro-devices with high precision requirements.

[0010] (2) By setting tear grooves, this utility model allows users to quickly separate the base layer from the film with a slight push after the initial adsorption of the film body. The operation is simple and no additional tools are required. This not only greatly improves the installation efficiency and reduces the workload, but also avoids the risk of damage to the functional layer of the film. At the same time, the tear groove layout is reasonable and the stress concentration is controllable, which is conducive to maintaining the overall stability of the film shape. It is especially suitable for reliable mounting of small sizes. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] This utility model provides a small-sized diaphragm that is easy to install, such as... Figure 1 and Figure 2 As shown, this embodiment includes a base layer 1, a membrane body 2 on top of the base layer 1, an adsorption layer 3 adsorbed on top of the membrane body 2, an extension strip 4 connected to the outside of the adsorption layer 3, a thin film 5 inside the base layer 1, the membrane body 2 adsorbed on top of the thin film 5, a tear groove 6 is opened on top of the base layer 1, and the base layer 1 is connected to the thin film 5 through the tear groove 6.

[0015] Specifically, the adsorption layer 3 is made of silicone, which has good adsorption performance and flexibility, and can adapt to the surface of products with different curvatures. By setting the adsorption layer 3 of silicone, it has excellent adsorption stability and deformation recovery ability. Silicone material has high surface adhesion and low modulus characteristics, which can achieve uniform adhesion to the surface of products with different curvatures, avoiding edge lifting or falling off due to stress concentration. The extension belt 4 is made of PET material, which has a certain strength and ductility, making it easy for users to grip and apply force. The PET material of the extension belt 4 gives it high mechanical strength and fatigue resistance. PET material has good tensile strength and dimensional stability, allowing users to apply force to the adsorption layer 3 smoothly and controllably during the traction process, avoiding installation failure due to deformation or breakage of the extension belt 4. The surface of the extension belt 4 can be frosted or micro-textured to enhance the grip and improve the ease of operation. The membrane 5 is a release membrane with an anti-stick treatment on its surface, which facilitates easy separation from the membrane body 2 during installation. The tear groove 6 is arranged in a ring or U shape, which makes it easy for the user to apply pushing force to separate the base layer 1 from the membrane 5. By setting the tear groove 6, the user can quickly separate the base layer 1 from the membrane 5 by slightly pressing the base layer 1 with their fingers at the end of the installation. The ring groove design is conducive to stress concentration and avoids irregular breakage during the tearing process, thereby protecting the integrity of the membrane body 2. The groove depth is usually controlled within the range that does not penetrate the base layer 1 but is prone to breakage, taking into account both structural strength and ease of operation.

[0016] The present invention provides a small-sized diaphragm that is easy to install, and its working principle is as follows: When the membrane is used to connect small-sized products, the adsorption layer 3 on the membrane body 2 can be brought into contact with the product through the base layer 1, and then the adsorption layer 3 can be pulled by the extension belt 4. When the adsorption layer 3 is slowly torn open, the membrane body 2 will adsorb with the product. Then, a pushing force is applied to the base layer 1 so that the membrane body 2 can be firmly fixed with the product, and the base layer 1 is separated from the film 5 through the tear groove 6. Then the film 5 is torn open.

[0017] This application, through the setting of an adsorption layer and an extension strip, allows for a smooth and controllable pulling of the adsorption layer during use, enabling the membrane body to gradually adhere to the product surface from one end to the other. This process achieves initial positioning and slow adsorption of the membrane, effectively eliminating internal air and significantly reducing the generation of air bubbles. At the same time, the extension strip provides a good control point for operating force, preventing overall displacement or twisting caused by improper adhesion in one step, greatly improving the accuracy and success rate of installation, and is especially suitable for surface protection of micro-devices with high precision requirements.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
