Description

Technical Field

[0001] This utility model relates to the field of headphone accessories, and in particular to a flexible buffer and headphone pad that enhances sound insulation. Background Technology

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. Headphones are generally detachable from the media player, connected via a plug. The advantage is that they allow for private listening without disturbing others; they also isolate ambient noise, which is helpful for those using them in noisy environments such as recording studios, bars, while traveling, or exercising. Originally designed for telephones and radios, headphones are now widely used with mobile phones, portable music players, radios, portable game consoles, and digital audio players, thanks to the prevalence of portable electronic devices.

[0003] To maintain softness and comfort, the earcups of over-ear headphones are usually made of foam. The foam is typically made by trimming a whole piece of foam with a foam trimming device so that it can fit into the headphone shell. This trimming method results in a large amount of foam loss and waste of resources.

[0004] Secondly, the sound insulation effect of a single fabric covering foam in the headphone pad is poor, affecting the sound quality of the headphones. Although those skilled in the art have made considerable efforts to improve the sound quality of headphones, such as attaching an adhesive layer to the inside of the fabric layer, in actual use, due to the deformation of the headphones under pressure, cavities will inevitably form between the fabric layer and the foam part of the headphone pad, resulting in leakage. In addition, the method of setting a sound insulation layer on the fabric layer makes the fabric layer thicker overall; therefore, after the fabric layer covers the foam, wrinkles will be generated, affecting the precision of the covering and splicing process and the appearance of the headphone pad.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a flexible buffer and headphone pad with enhanced sound insulation. Through the design of a sealed sound-insulating component and a soft rubber layer, when the headphone pad is worn and compressed, the sealed sound-insulating component and the flexible buffer together bulge outward. The sealed sound-insulating component and the soft outer casing of the headphone pad form a tight fit, improving the tightness of the fit and minimizing the gaps between the foam part and the soft outer casing. This improves the airtightness of the headphone pad, reduces leakage, and effectively improves the sound quality of the headphones.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A flexible buffer body with enhanced sound insulation includes a flexible buffer body, a sealing sound insulation component, and a soft rubber layer. The flexible buffer body has a front and a back side disposed on opposite sides. The sealing sound insulation component is disposed on the front and / or back side of the flexible buffer body, and the soft rubber layer is disposed on the outer side of the flexible buffer body.

[0009] As a preferred embodiment, the sealing and sound-insulating component includes a silicone sheet, which is adhered to the front and / or back of the flexible buffer.

[0010] As a preferred embodiment, the sealing and sound-insulating component further includes a protective film, which is applied to the front and / or back of the flexible buffer body; the silicone sheet is adhered to the outside of the protective film.

[0011] As a preferred embodiment, one end of the flexible buffer is wound around the other end to form a ring-shaped flexible buffer.

[0012] As a preferred embodiment, the annular silicone sheet is bonded to the front or back of the annular flexible buffer.

[0013] As a preferred embodiment, the flexible buffer body has gradually thinned at both ends; the flexible buffer body is made of foam, sponge, or fiber material.

[0014] As a preferred embodiment, the flexible buffer body is integrally stamped.

[0015] As a preferred embodiment, the soft rubber layer is a deformable soft rubber.

[0016] An earphone pad includes a flexible buffer body and a soft outer cover, wherein the flexible buffer body is any of the aforementioned flexible buffer bodies with enhanced sound insulation, and the soft outer cover covers the flexible buffer body.

[0017] As a preferred embodiment, a sound-insulating block is also provided between the soft outer casing and the flexible buffer body.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses the design of a sealing sound insulation component and a soft rubber layer. In this way, when the finished headphones are worn and used, the headphone pad is squeezed, and the sealing sound insulation component and the flexible buffer body bulge outward together. The sealing sound insulation component and the soft outer packaging of the headphone pad form a tight fit, which improves the tightness of the fit and minimizes the phenomenon of gaps between the foam part and the soft outer packaging. This improves the airtightness of the headphone pad, reduces leakage, and effectively improves the sound quality of the headphones.

[0019] Secondly, one end of the flexible buffer body is wound towards the other end to form a ring-shaped flexible buffer body, so that the silicone sheet is adhered to the front or back of the flexible buffer body. In this way, the long strip-shaped flexible buffer body is rolled into a roll when it is wound up, which improves the material utilization efficiency. The foam is rolled into a roll when it is wound up, which does not generate waste, reduces related processes, improves production efficiency, and at the same time reduces material loss.

[0039] A flexible buffer 30 with enhanced sound insulation includes a flexible buffer 10, a sealing sound insulation component 11, and a soft rubber layer 50.

[0040] The flexible buffer 10 has a front and a back side arranged on opposite sides; the front and / or back of the flexible buffer are provided with a sealing and sound-insulating component 11 for improving the sound insulation effect; the front and / or back of the sealing and sound-insulating component 11 are provided with a soft rubber layer 50.

[0041] The soft rubber layer 50 is disposed on the outer side of the flexible buffer body 10. In this embodiment, the soft rubber layer 50 can be disposed on the upper end surface and / or lower end surface and / or peripheral surface of the flexible buffer body 10, and the appropriate placement method can be selected according to actual needs. Preferably, the soft rubber layer is deformable soft rubber.

[0042] The soft rubber layer is ring-shaped, but in this embodiment, it can also be circular, elliptical, racetrack-shaped, rectangular, etc., which can be selected according to actual needs; the outer surface of the soft rubber layer is also provided with an outer film, which reduces the adhesiveness of the soft rubber surface; the thickness of the soft rubber layer is 1mm-30mm; the soft rubber layer can be made of metal rubber, PU, ​​TPE, TPU, or AB soft rubber, and the appropriate material can be selected according to actual needs.

[0043] Preferably, the flexible buffer 10 is made of foam, sponge, or fiber. Preferably, the flexible buffer 10 has tapered ends. Preferably, the thickness of the flexible buffer 10 is 2mm-15mm, and can be selected according to actual needs. Preferably, the flexible buffer is a long strip-shaped sheet. The width of the long strip-shaped flexible buffer does not need to be the same throughout its length.

[0044] The flexible buffer 10 has a protective film 12 on its front and / or back sides. Preferably, the protective film 12 is a silicone film, a PE film, or a plastic film. The plastic film can be made of PP, PET, PVC, or PA, etc., and the appropriate material can be selected according to actual needs.

[0045] In actual use, the protective membrane 12 seals the gaps in the flexible buffer 10, forming a tight fit and improving the tightness of the fit. The silicone membrane is soft and elastic, which can better conform to the contour of the human ear, reduce the pressure of the headphones on the ears, and make the ears feel more comfortable even after wearing for a long time. The silicone membrane has good sound insulation and sound leakage prevention effects, which can reduce the interference of external environmental noise on music, and at the same time prevent sound leakage inside the headphones, so that users can get a clearer and purer listening experience. It can provide a relatively stable environment for sound propagation, so that the sound can be more concentrated into the ear canal, thereby improving the sound quality, such as increasing the texture and quantity of low frequencies, and also increasing the performance of musical details.

[0046] A protective film can reduce the adhesion of the soft adhesive layer surface. Other methods can also be used to reduce surface adhesion, such as applying powder or a dryable liquid adhesive, which dries to form a non-adhesive surface. The appropriate method to reduce the adhesion of the soft adhesive layer surface can be selected according to actual needs.

[0047] A silicone sheet 13 is adhered to the outside of the protective film 12; one end of the flexible buffer body 10 is wound towards the other end to form an annular foam body 20, so that the silicone sheet 13 is adhered to the front or back of the flexible buffer body 10.

[0048] In this embodiment, it can be wound in multiple layers as needed, which will not be elaborated here. It can be wound from the outside to the inside to form a ring-shaped foam body, or it can be wound from the inside to the outside to form a ring-shaped foam body. The appropriate winding method can be selected according to actual needs.

[0049] The flexible buffer body is integrally stamped. In actual manufacturing, a protective film 12, a silicone sheet 13, and a soft rubber layer can be directly applied to the integrally stamped flexible buffer body. This method makes the forming of the flexible buffer body simple and quick. The appropriate forming method can be selected according to actual needs, which will not be elaborated here.

[0050] When the finished headphones are worn, the headphone pads are compressed, and the silicone sheet, protective film, and annular foam bulge outward together. The silicone sheet, protective film, and soft outer casing of the headphone pads form a tight fit, which improves the tightness of the fit and minimizes the gap between the foam and the soft outer casing. This improves the airtightness of the headphone pads, reduces leakage, and effectively improves the sound quality of the headphones.

[0051] like Figure 1 The illustration discloses a first scenario of the flexible buffer 10 in this embodiment, wherein a protective film 12 is provided on the front side of the flexible buffer 10, and a silicone sheet 13 is adhered to the outside of the protective film 12.

[0052] like Figure 9 The illustration discloses a second scenario of the flexible buffer 10 in this embodiment, wherein a protective film 12 is provided on the back side of the flexible buffer 10, and a silicone sheet 13 is adhered to the outside of the protective film 12.

[0053] like Figure 10 The illustration discloses a third scenario of the flexible buffer 10 in this embodiment, wherein a protective film 12 is provided on both the front and back sides of the flexible buffer 10, and a silicone sheet 13 is adhered to the outside of the protective film 12.

[0054] An earphone pad includes a foam 30 and a soft outer covering 40. The foam 30 is the aforementioned flexible cushioning body 30 that enhances sound insulation. The soft outer covering 40 covers the foam 30. Preferably, the soft outer covering 40 is made of leather or fabric. Since only structural modifications are needed to the foam 30 portion, the design and application of the soft outer covering 40 are not limited. Furthermore, when the soft outer covering 40 covers the foam 30 portion, wrinkles do not occur as in traditional technologies, reducing processing difficulty and ensuring the aesthetic appearance of the earphone pad.

[0055] like Figure 6 The diagram illustrates the structure of an earphone pad according to this embodiment, wherein a soft rubber layer 50 is provided on both the front and back of the sealing and sound-insulating component; as shown... Figure 7 The diagram illustrates the structure of the headphone pad in this second embodiment, where a soft rubber layer 50 is provided on the front side of the sealing and sound-insulating component; as shown... Figure 8 The diagram shows the structure of the headphone pad in this embodiment three, with a soft rubber layer provided on the back of the sealing and sound-insulating component;

[0056] In this embodiment, for example, when the front and / or back of the sealing and sound-insulating component is provided with a soft rubber layer, the soft rubber design near the ear provides better wearing comfort and a certain cooling effect when the finished headphones are worn.

[0057] Preferably, a sound-insulating block 60 is provided between the soft outer casing 40 and the flexible buffer body 30. The sound-insulating block 60 can be a sponge, or it can be coated with polyurethane foam, sound-insulating sealant, silicone sealant, epoxy resin, or neoprene rubber adhesive. The choice can be made according to actual needs and will not be elaborated here.

[0058] The key design feature of this invention lies in its use of a sealing and sound-insulating component and a soft rubber layer. When the earphone is worn, the earphone pad is compressed, causing the sealing and sound-insulating component and the flexible buffer to bulge outward together. This creates a tight fit between the sealing and sound-insulating component and the soft outer casing of the earphone pad, improving the tightness of the fit and minimizing gaps between the foam and the soft outer casing. This enhances the airtightness of the earphone pad, reduces leakage, and effectively improves the sound quality of the earphone.

[0059] Secondly, one end of the flexible buffer body is wound towards the other end to form a ring-shaped flexible buffer body, so that the silicone sheet is adhered to the front or back of the flexible buffer body. In this way, the long strip-shaped flexible buffer body is rolled into a roll when it is wound up, which improves the material utilization efficiency. The foam is rolled into a roll when it is wound up, which does not generate waste, reduces related processes, improves production efficiency, and at the same time reduces material loss.

[0060] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
