Description

Technical Field

[0001] This utility model relates to a diaphragm, and more particularly to an integrated structure of voice coil lead diaphragm in OWS. Background Technology

[0002] OWS (Open Wearable Stereo) is a novel wearable audio technology that utilizes air conduction. It transmits sound wave vibrations, converted from electrical signals, directly to the auditory nerve via the temporal bone through traditional air conduction media such as the outer eardrum, tympanic membrane, and tympanic cavity. This open-back design allows users to enjoy music while simultaneously hearing ambient sounds, enhancing safety. It also boasts high sound quality, lightweight construction, and durability. In traditional loudspeakers, the voice coil leads are typically suspended or fixed to a support, making them susceptible to fatigue damage from vibration. This is especially true in OWS applications, where the operating environment is more prone to large amplitude vibrations, further increasing the risk of lead breakage, diaphragm deformation, and vibration imbalance. Utility Model Content

[0003] Therefore, it is necessary to provide an integrated voice coil lead diaphragm structure for OWS to address the shortcomings of existing technologies.

[0004] An OWS voice coil leaded diaphragm integrated structure includes a diaphragm body and a voice coil lead integrally connected to the diaphragm body. The voice coil lead includes a lead layer and electrode contacts. The lead layer is integrally formed on the top surface of the diaphragm body, and the electrode contacts are disposed on the bottom surface of the diaphragm body. The electrode contacts and the lead layer are connected by an electrical connection part.

[0005] Furthermore, a lead wire groove is provided on the outer surface of the diaphragm body, and the lead wire layer is embedded in the lead wire groove.

[0006] Furthermore, the lead layer is attached to the outer surface of the diaphragm body.

[0007] Furthermore, a through hole is provided on the central part, and an electrical connection part is disposed in the through hole. The lead layer and electrode contacts are respectively connected to the two ends of the electrical connection part.

[0008] Furthermore, the size of the electrode contacts is larger than that of the electrical connection portion.

[0009] Furthermore, the diaphragm body includes a central portion and a suspension portion disposed on its outer periphery, the inner end of the voice coil lead extends on the central portion and the suspension portion, and the outer end extends out of the outer side of the diaphragm body.

[0010] Furthermore, there are two voice coil leads, which are distributed on two opposite sides of the diaphragm body and are evenly staggered.

[0011] Furthermore, the voice coil leads are made of silver-copper alloy or gold-plated copper, and the diaphragm body is made of a polymer film.

[0012] Furthermore, the lead layer is an electroplated layer, which is attached to the outer surface of the diaphragm body.

[0013] In summary, this invention integrates the voice coil lead with the diaphragm body, with the lead embedded or deposited on the diaphragm surface, reducing the risk of fatigue damage caused by suspended leads in traditional structures. It also improves vibration balance; the integrated structure results in a more uniform mass distribution of the diaphragm body, effectively reducing distortion caused by vibration imbalance, especially during large amplitude operation. Furthermore, it is adaptable to various application scenarios, meeting the high requirements for speaker structural stability and sound quality in OWS (Out-of-Screen) wearing environments. In addition, when OWS is used in outdoor, sports, or everyday wearing environments, the integrated design effectively alleviates stress concentration, improves stability, and solves the problem of large amplitude vibration. It is highly practical and has significant potential for widespread adoption. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] like Figures 1 to 3 As shown, this utility model provides an integrated voice coil lead diaphragm structure for OWS. The integrated voice coil lead diaphragm structure for OWS includes a diaphragm body 10 and a voice coil lead 20, wherein the voice coil lead 20 is integrally formed on the diaphragm body 10.

[0019] The diaphragm body 10 includes a central portion 11 and a suspension portion 12 disposed on its outer periphery. The inner end of the voice coil lead 20 extends on the central portion 11 and the suspension portion 12, and the outer end extends outward from the outside of the diaphragm body 10. The voice coil lead 20 includes a lead layer 21 and electrode contacts 22. The lead layer 21 is integrally formed on the diaphragm body 10. The electrode contacts 22 are disposed on the bottom surface of the central portion 11 of the diaphragm body, and the lead layer 21 is disposed on the top surface of the central portion, and the electrode contacts 22 are electrically connected to the lead layer 21.

[0020] Specifically, a through hole is provided on the central portion 11, and an electrical connection portion 111 is disposed within the through hole. The electrical connection portion 111 is connected to the electrode contact 22 and the lead layer 21. Further, it can be understood that in another embodiment, the outer diameter of the electrical connection portion 111 is smaller than that of the electrode contact 22 and the lead layer 21, so that both ends of the electrical connection portion 111 can be limited and are not easily detached from the diaphragm body 10.

[0021] In this embodiment, the lead layer 21 is a conductive material, comprising an outer extension 211 and an inner integral connecting portion 212, the connecting portion 212 being integrally connected to the outer surface of the diaphragm body 10. In one embodiment, the connecting portion 212 is embedded in the outer surface of the diaphragm body 10. Specifically, a lead groove is pre-set on the top surface of the substrate of the diaphragm body 10, the conductive lead layer 21 is embedded in the lead groove, and then the substrate of the diaphragm body 10 and the lead layer 21 are placed into a mold and integrally formed by high temperature pressing, thus combining the diaphragm body 10 and the lead layer 21 into an integral structure. This integrally formed structure ensures that the two are tightly bonded and not easily detached.

[0022] In another embodiment, the lead layer 21 is surface-attached to the surface of the diaphragm body 10. One method of surface attachment is to directly electroplate the lead layer 21 onto the outer surface of the diaphragm body 10 using electroplating. If a lead groove is not provided at the electroplating location, the lead layer 21 is formed directly on the top surface of the diaphragm body 10. Of course, it is understood that the required lead layer 21 can also be formed by electroplating within a lead groove. Furthermore, the electroplating of the lead layer 21 can employ conventional techniques in the electroplating field. When electroplating the extension 211, a separable substrate can be used for electroplating, and after electroplating, the substrate can be removed, leaving the extension. This specific electroplating method is also existing technology in the electroplating field; therefore, its specific steps will not be described in detail here. Of course, it is understood that the surface attachment method of this invention is not limited to electroplating.

[0023] In this embodiment, two voice coil leads 20 are provided, distributed on two opposite sides of the diaphragm body 10 and evenly staggered. Furthermore, in this embodiment, the voice coil leads 20 are made of silver-copper alloy or gold-plated copper, which have the advantages of high conductivity and strong fatigue resistance. The diaphragm body 10 is made of a polymer film, which has the characteristics of lightweight and high durability.

[0024] During operation, the diaphragm body 10 vibrates under the drive of the voice coil magnetic field. The electrical signal is converted into mechanical vibration through the voice coil lead 20, which in turn drives the air to vibrate and produce sound. Because the voice coil lead 20 is integrally set with the diaphragm body 10, the voice coil lead 20 moves synchronously with the diaphragm body 10, which significantly reduces the vibration imbalance caused by large amplitude movements, reduces the risk of lead breakage, and improves structural stability and acoustic performance.

[0025] In summary, this invention integrates the voice coil lead 20 with the diaphragm body 10, with the lead 20 embedded or deposited on the surface of the diaphragm body 10, reducing the risk of fatigue damage caused by suspended leads in traditional structures. It also improves vibration balance; the integrated structure makes the mass distribution of the diaphragm body 10 more uniform, effectively reducing distortion caused by vibration imbalance, especially during large amplitude operation. Furthermore, it is adaptable to various application scenarios, meeting the high requirements for speaker structural stability and sound quality in OWS wearing scenarios. In addition, when OWS is used in outdoor, sports, or daily wearing environments, the integrated design can effectively alleviate stress concentration, improve stability, and solve the problem of large amplitude vibration. It is highly practical and has significant potential for widespread adoption.

[0026] The embodiments described above only illustrate some implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
