Abstract
Description
Technical Field
[0001] This utility model relates to the field of sound protection equipment manufacturing technology, specifically to a music earplug for noise reduction. Background Technology
[0002] With the rapid development of modern society and the continuous improvement of living standards, contemporary people lead fast-paced lives with rich nightlife, especially in noisy environments such as concerts, music festivals, and nightclubs. These environments are filled with various audio frequencies, including some harmful to the eardrums and excessively high frequencies unrelated to the music itself. Most young people in these settings lack awareness of ear protection, which not only affects their work efficiency and quality of life but also negatively impacts their physical health, such as hearing loss, sleep disorders, and increased psychological stress. Therefore, music noise cancellation technology has become particularly important in various products, and music earbuds are one such innovative solution. Music earbuds combine audio technology and noise isolation technology to provide a superior listening experience. Traditional earbuds typically focus on comfort and basic noise isolation; for example, 3M earbuds usually use passive noise cancellation. However, earbuds unevenly reduce volume, causing the heard music to deviate from its intended high, mid, and low frequencies.
[0003] According to the Chinese Utility Model Publication No. CN218634213U, a noise-reducing and sound-insulating earplug is disclosed. This utility model can absorb external noise through sound-absorbing cotton 2, preventing external noise from entering the ear canal through the vent hole 1011 and the vent channel.
[0004] However, there are some issues to consider when implementing the above technical solutions: First, the device mainly uses sound-absorbing cotton for sound insulation, which absorbs sound waves and reduces the reflection and propagation of sound in space, thereby reducing noise levels. It mainly relies on the density and structure of materials, such as polyester fiber or mineral wool, to effectively block sound. However, in the field of vocal music, using only sound-absorbing cotton for noise reduction does not reduce the puncture of some audio frequencies on the eardrum to a certain extent, thus failing to protect the eardrum. Furthermore, using only sound-absorbing cotton for noise reduction can also damage the quality of the vocal music itself, altering the music's frequency and making it impossible to coexist harmoniously with the vocal music. Utility Model Content
[0005] The purpose of this invention is to provide a noise-canceling earplug for music, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a music earplug for noise reduction, comprising an inner ear kit and a noise reduction component, wherein a noise reduction component is provided at one end of the inner ear kit, an inner ear sleeve retainer is provided on one side of the inner ear kit, an outer ring is provided on one side of the inner ear sleeve retainer, and a thin film is provided on one side of the outer ring.
[0007] Preferably, an inner ear sleeve retainer is fixedly connected to the lower part of the inner ear kit, and a cylindrical hole is opened inside the inner ear kit and a cylindrical hole is opened inside the inner ear sleeve retainer. The diameter of the cylindrical hole opened inside the inner ear kit is larger than the diameter of the cylindrical hole opened inside the inner ear sleeve retainer.
[0008] Preferably, a pad is fitted inside the lower part of the inner ear sleeve retainer, the diameter of the pad is smaller than the diameter of the cylindrical hole opened inside the inner ear sleeve retainer, and the pad is made of nylon.
[0009] Preferably, an outer ring is provided below the pad, and the diameter of the pad corresponds to the diameter of the outer ring.
[0010] Preferably, a thin film is adhered to the surface of the outer ring, and the thin film is made of PU film.
[0011] Preferably, an outer ear sleeve is provided below the PU film. The outer ear sleeve is made of ABS plastic. An outer ear sleeve groove is provided at the upper end of the outer ear sleeve. The outer diameter of the outer ear sleeve matches the inner diameter of the inner ear sleeve retaining ring.
[0012] Preferably, an ear cover buckle is fixedly connected to the lower part of the ear cover, and the ear cover buckle has an inlet hole inside.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention achieves effective noise isolation through a combination of an inner ear kit, an inner ear sleeve retainer, an outer ring, and a diaphragm. The different diameters of the inner ear sleeve retainer and the inner ear kit ensure stable fixation of the padding and outer ring, preventing components from slipping during use. The nylon padding effectively prevents earwax from contaminating the PU diaphragm while softening sound, thus maintaining good noise reduction. The varying thicknesses of the PU diaphragm can be adjusted according to the type of music, precisely filtering unwanted frequencies, reducing environmental noise interference, and improving the clarity and indistinguishability of the music.
[0015] Furthermore, the outer ear tips and their matching slots provide additional fixation and protection, ensuring the earbud components are stable and easy to disassemble and clean. The sound inlet in the outer ear tip buckle further optimizes sound transmission, making the headphones perform better in frequency filtering and noise reduction. This combined approach not only improves the sound quality for musicians, ensuring a smooth noise reduction curve without altering the frequency response of the received music, but also guarantees clear, original music playback. Simultaneously, the nylon padding on the PU membrane eliminates excessively high-frequency noise, protecting the ears and preventing damage. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-5 An embodiment of this utility model is provided: a music earplug for noise reduction, including an inner ear kit 1 and a noise reduction component 2. The noise reduction component 2 is provided at one end of the inner ear kit 1, an inner ear retainer 201 is provided on one side of the inner ear kit 1, an outer ring 203 is provided on one side of the inner ear retainer 201, and a thin film 204 is provided on one side of the outer ring 203.
[0027] Specifically, an inner ear sleeve retainer 201 is fixedly connected to the lower part of the inner ear kit 1. The inner ear kit 1 has a cylindrical hole inside, and the inner ear sleeve retainer 201 has a cylindrical hole inside. The diameter of the cylindrical hole inside the inner ear kit 1 is larger than the diameter of the cylindrical hole inside the inner ear sleeve retainer 201. The different diameter design can ensure that the pad 202 and the outer ring 203 will not slip out of the hole, which plays a certain role in limiting the movement.
[0028] Specifically, a pad 202 is fitted inside the inner ear sleeve 201. The diameter of the pad 202 is smaller than the diameter of the cylindrical hole opened inside the inner ear sleeve 201. The pad 202 is made of nylon and can play a certain role in keeping clean, preventing earwax from sticking to the surface of the PU membrane and affecting the noise reduction effect.
[0029] Specifically, an outer ring 203 is provided below the pad 202. The diameter of the pad 202 corresponds to the diameter of the outer ring 203, and they can be nested inside the inner ear sleeve retainer 201 to ensure the effectiveness of use.
[0030] Specifically, a thin film 204 is adhered to the surface of the outer ring 203. The thin film 204 is made of PU film. Different thicknesses of PU film can be cut according to different vocal types to selectively filter unwanted vocal frequencies, thereby reducing environmental interference, enhancing the identification of vocal frequencies, and improving music quality.
[0031] Specifically, an outer ear sleeve 205 is provided below the PU film 204. The outer ear sleeve 205 is made of ABS plastic. An outer ear sleeve groove 206 is provided at the upper end of the outer ear sleeve 205. The outer diameter of the outer ear sleeve 205 matches the inner diameter of the inner ear sleeve retaining ring 201, so that the outer ear sleeve 205 can be inserted into the inner ear sleeve retaining ring 201 to achieve a detachable function. The outer ear sleeve groove 206 can fit the pad 202 and the outer ring 203, which serves as a limiting and fixing function.
[0032] Specifically, an outer ear cover buckle 207 is fixedly connected to the lower part of the outer ear cover 205. The outer ear cover buckle 207 has an inlet opening 208 inside, which allows the sound to be transmitted to the headphones for frequency filtering and noise filtering.
[0033] Working principle: First, place the pad 202 inside the hole at the bottom of the inner ear sleeve clasp 201. Then, place the outer ring 203 with the PU film 204 on the outer ear sleeve slot 206. Finally, insert the outer ear sleeve 205 into the inner hole of the inner ear sleeve clasp 201 to complete the earbud assembly. When wearing, insert the inner ear kit 1 into the wearer's ear canal. By controlling the thickness of the PU film, for example, a 10-20μm PU film is suitable for filtering music noise in the mid-to-high frequency range. This film thickness can effectively isolate noise in the frequency range of approximately 1kHz to 10kHz. For low-frequency noise (such as below 1kHz), thicker material is usually required. Therefore, a 10-20μm PU film is mainly used to improve the clarity of mid-to-high frequency music while reducing environmental interference. In this way, it can effectively isolate external noise, but its focus is on preserving the clarity and quality of the audio, filtering out unwanted noise, and maintaining the detail and layering of the music, especially in the high-frequency and low-frequency sound quality performance.
[0034] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
