Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an earphone with a sound-adjusting hole shielding plate. Background Art

[0002] Headphones are an audio device worn on the head, with earcups covering the ears. They offer numerous advantages. First, they offer excellent sound quality, with larger earcups providing richer sound details and more powerful low-frequency effects. Second, they are comfortable to wear, without the pressure on the ear canal that can occur with in-ear headphones. Furthermore, headphones typically offer excellent sound insulation, allowing you to immerse yourself in your music without external distractions. They are also stylish and available in a variety of styles and colors. Furthermore, some headphones also feature noise cancellation, further enhancing the listening experience. Whether studying or working indoors or traveling outdoors, headphones provide high-quality music enjoyment, making them an ideal choice for music lovers and those seeking a comfortable listening experience.

[0003] The opening of the existing earphones may cause sound leakage from the earphone cavity. Since the outside is connected to the earphone cavity, the headset may produce inaccurate sound. Utility Model Content

[0004] In order to overcome the above technical problems, the utility model provides an earphone with a tuning hole shielding plate, which is used to improve the problem of inaccurate music caused by sound leakage of the earphone.

[0005] In order to achieve the above-mentioned purpose, the present invention proposes an earphone with a tuning hole baffle, which includes an ear shell and a through hole formed on the ear shell and connected to the interior of the ear shell. A baffle is fixedly provided on the outer wall of the ear shell to block the outside of the through hole. A sound-blocking plate is provided on the baffle, one side of which is fixed to the baffle and the other side extends into the interior of the through hole.

[0006] When headphones play music, the speakers inside them vibrate significantly due to their large size. If the headphones were fully enclosed, the pressure fluctuations would hinder the speakers' normal vibration, affecting their sound quality. However, if the headphones were equipped with perforations to equalize the pressure, sound would leak from the chamber, degrading the sound quality and potentially causing loss of stereo sound or other impairments.

[0007] A through hole is provided on the ear shell, and a baffle fixed to the ear shell is provided outside the through hole, so that the through hole can be blocked to a certain extent from the outside, and by providing a sound-blocking plate extending into the through hole, the sound waves generated by the sound-generating unit can be further blocked from escaping from the through hole. At the same time, air circulation inside and outside the ear shell can be maintained, ensuring that the air pressure generated by the large vibration amplitude of the speaker when working can completely flow into the gap between the baffle and the sound-blocking plate, and ensuring that the proportion of sound leakage is extremely low, thereby effectively ensuring that the sound quality of the earphones will not be damaged.

[0008] Preferably, the shielding plate includes a back plate and a support plate, the support plate is fixed to the outside of the ear shell, and the back plate is plugged into the support plate.

[0009] The support plate is fixed to the outer wall of the ear shell and supports the back panel, which is equipped with a sound barrier. During installation or replacement, the back panel is plugged into the support plate and the sound barrier inserted into the through hole. This blocks sound from escaping the ear shell while ensuring air pressure inside and outside the ear shell is connected, without affecting the normal operation of the speaker. Furthermore, if the sound barrier becomes damaged after long-term use, simply remove the back panel and replace it with a new one with the sound barrier.

[0010] Preferably, a side of the back plate close to the ear shell is provided with sound-absorbing cotton circumferentially surrounding the sound-absorbing plate.

[0011] At the bottom of the sound insulation board, sound-absorbing cotton is set around and wrapped around the sound insulation board to further prevent sound leakage. At the same time, since the sound-absorbing cotton has breathable properties, it can connect the air pressure inside and outside the ear shell to ensure the normal operation of the speaker.

[0012] Preferably, corrugated raised strips are formed on two planes of the sound insulation plate.

[0013] Corrugated raised strips are formed on the two planes of the sound-absorbing board, and their function is to further absorb sound waves and avoid sound leakage.

[0014] Preferably, the sound-absorbing panels are a plurality of partitions arranged in parallel.

[0015] Multiple partitions can absorb sound waves separately, thereby increasing the area for absorbing sound waves and improving the efficiency of absorbing sound waves.

[0016] Preferably, sound guide tubes are installed between adjacent partitions.

[0017] One of the functions of the sound guide tube is to guide part of the sound waves to between the partitions, guide the sound waves to the inside to be absorbed by the partitions, and increase the efficiency of absorbing sound waves.

[0018] Preferably, one end of the sound guide tube close to the back plate extends to the sound-absorbing cotton.

[0019] The sound guide tube guides the sound waves to the sound-absorbing cotton installed on the back panel. The sound waves are absorbed by the sound-absorbing cotton and the overall sound waves are dispersed, so that the sound-absorbing cotton can absorb sound to the greatest extent.

[0020] The earphones with tuning hole baffle provided by the utility model can realize secondary interception of internal sound waves by arranging the baffle outside the through hole of the ear shell, and can realize primary interception of sound waves by arranging the sound blocking plate extending into the through hole on the baffle. The intercepted sound waves will not affect the sound quality of the internal speaker, and at the same time, it ensures that the air pressure inside and outside the ear shell is connected, avoiding the disadvantage of the speaker not being able to work normally.

[0031] Support plate 6 is fixed to the outer wall of concha 1 and supports back plate 5. Sound damping plate 4 is mounted on back plate 5. During installation or replacement, back plate 5 is plugged into support plate 6 and sound damping plate 4 is inserted into through-hole 2. This prevents sound from escaping from concha 1 while ensuring air pressure communication between the inside and outside of concha 1, without affecting the normal operation of the speaker. Furthermore, if sound damping plate 4 becomes damaged after prolonged operation, it can be simply removed and replaced with a new one with sound damping plate 4.

[0032] In one embodiment of the present invention, a side of the back plate 5 close to the ear shell 1 is provided with sound-absorbing cotton 7 circumferentially surrounding the sound-absorbing plate 4.

[0033] At the bottom of the sound-proof plate 4, sound-absorbing cotton 7 is arranged around and wrapped around the sound-proof plate 4, which can further prevent sound leakage. At the same time, since the sound-absorbing cotton 7 has breathable properties, it can connect the air pressure inside and outside the ear shell 1 to ensure the normal operation of the speaker.

[0034] In one embodiment of the present invention, corrugated raised strips 8 are formed on two planes of the sound insulation plate 4 .

[0035] Corrugated raised strips 8 are formed on two planes of the sound-absorbing plate 4, and their function is also to further absorb sound waves and prevent sound leakage.

[0036] In one embodiment of the present invention, the sound-absorbing plate 4 is a plurality of partition plates 9 arranged in parallel.

[0037] The plurality of partitions 9 can absorb sound waves separately, thereby increasing the area for absorbing sound waves and improving the efficiency of absorbing sound waves.

[0038] In one embodiment of the present invention, a sound guide tube 10 is installed between adjacent partitions 9 .

[0039] One of the functions of the sound guide tube 10 is to guide a portion of the sound waves between the partitions 9 and guide the sound waves into the interior to be absorbed by the partitions 9, thereby increasing the efficiency of absorbing the sound waves.

[0040] In one embodiment of the present invention, one end of the sound guide tube 10 close to the back plate 5 extends to the sound-absorbing cotton 7 .

[0041] The sound guide tube 10 guides the sound waves to the sound-absorbing cotton 7 provided on the back plate 5 , and the sound-absorbing cotton 7 absorbs the sound waves and disperses the overall sound waves, so that the sound-absorbing cotton 7 can achieve sound absorption to the greatest extent.

[0042] The earphones with tuning hole baffles provided by the present invention can achieve secondary interception of internal sound waves by arranging the baffle 3 outside the through hole 2 of the ear shell 1, and can achieve primary interception of sound waves by arranging the sound blocking plate 4 extending into the through hole 2 on the baffle 3. The intercepted sound waves will not affect the sound quality of the internal speaker, and at the same time, it ensures that the air pressure inside and outside the ear shell 1 is connected, avoiding the disadvantage of the speaker not being able to work normally.

[0043] Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions and conversions can be made without exceeding the spirit and scope of the present invention as defined by the appended claims. Moreover, the scope of this application is not limited to the specific embodiments of the processes, devices, means, methods and steps described in the specification.
