A new type of automatic pressure relief earphone

Abstract

This utility model discloses a novel automatic pressure-releasing headphone, comprising: a shell with a connecting hole in the shell, a plug hole on the outer side of one end of the connecting hole, a support plate, a hollow connecting tube on the support plate, the outer dimension of the connecting tube matching the inner dimension of the connecting hole, and the inner dimension of the connecting tube matching the outer dimension of the plug hole; and ear tips on the shell. This novel automatic pressure-releasing headphone allows for effective release of pressure within the enclosed space formed by the ear tips and the head during wear, through the connecting hole and the connecting tube structure on the support plate. This avoids the deformation and cracking problems caused by long-term compression or stretching of the ear tips due to pressure accumulation in the sealed space, as seen in traditional headphones, significantly improving the lifespan and wearing comfort of the ear tips.

Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically to a novel automatic pressure-releasing headphone. Background Technology

[0002] When wearing headphones, the earcups fit snugly against the head, creating a sealed space for good sound insulation and conduction. However, in actual use, as the wearing time increases or the wearer's head movements change, the air pressure within this sealed space can fluctuate due to factors such as temperature changes and heat dissipation from the head. Since most current headphones lack an effective pressure relief structure, the pressure within the sealed space cannot be released in a timely manner, resulting in continuous pressure on the earcups.

[0003] Currently, the design of headphones on the market often focuses more on sound quality, appearance, and battery life, while neglecting the pressure issues caused by the seal during wear. When the pressure within the sealed space remains unbalanced for an extended period, the edges of the earcups that contact the head will experience significant compressive or tensile forces, leading to deformation, cracking, or even damage. Damaged earcups not only affect wearing comfort and noise isolation but may also shorten the headphones' lifespan and increase user costs. Utility Model Content

[0004] The purpose of this invention is to provide a novel automatic pressure-releasing headphone to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel automatic pressure-reducing earphone, comprising:

[0006] The outer casing has a connecting hole, and a plug-in hole is provided on the outer side of one end of the connecting hole;

[0007] A support plate is provided with a hollow connecting tube, the outer dimension of which matches the inner dimension of the connecting hole, and the inner dimension of which matches the outer dimension of the insertion hole.

[0008] Preferably, the outer shell is provided with ear covers.

[0009] Preferably, there is at least one connection hole, which is arranged in a ring array in the outer casing.

[0010] Preferably, the number of connecting holes is the same as the number of connecting pipes, and they are connected and sealed to each other.

[0011] Preferably, one end of the outer casing is connected to a sealing plate, and the connection is not sealed.

[0012] Preferably, the outer casing is provided with a connecting plate for fastening and connecting with the sealing plate.

[0013] Preferably, the support plate is disposed in the connecting plate, and the connecting plate also engages with the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the new automatic pressure relief headphones enable the pressure in the closed space formed by the earcups and the head when wearing headphones to be effectively released through the connecting holes and the connecting tube structure on the support plate. This avoids the deformation and cracking problems caused by the long-term compression or pulling of the earcup edges due to the accumulation of pressure in the sealed space of traditional headphones, and significantly improves the service life and wearing comfort of the earcups.

[0015] This new type of automatic pressure relief headphone works by inserting a connecting tube into a connector hole, and the connector hole into the connecting tube, which allows the connector hole to seal and release pressure into the connecting tube. This ensures that there is no possibility of leakage during pressure relief, thus preventing damage to the speaker. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a novel automatic pressure-reducing headphone, comprising:

[0025] The outer shell 2 has a connection hole 23. The ear tips 1 and the outer shell 2 form the front chamber. When wearing the headphones, the head will contact the ear tips 1 and generate a certain pressure. One end of the connection hole 23 has a plug hole 22 on the outside. The ear tips 1 are provided on the outer shell 2, and the diaphragm is provided on the speaker 4. When the airflow blows on the diaphragm, it will deform and produce abnormal noise. The low frequency will drop, and the PNC effect will also deteriorate. One end of the outer shell 2 is connected to a sealing plate 3, which is not sealed. The non-sealed connection is used to discharge airflow to release the pressure in the front chamber.

[0026] Compared to the drawbacks of traditional headphones where earcups are damaged due to pressure buildup in sealed environments, this invention takes a different approach. By combining the connecting tube 51 of the support plate 5, a complete pressure release system is constructed. This design not only effectively reduces the risk of earcups 1 deforming and cracking under long-term pressure, but also significantly improves the comfort and durability of the headphones. Furthermore, the annular array of connecting holes 23 in the outer shell 2 ensures uniform pressure distribution, guaranteeing stable and reliable pressure release. The ingenious design of the size matching between the connecting tube 51, connecting holes 23, and insertion holes 22 greatly simplifies the product assembly process while ensuring tight connection and sealing performance of components. The non-sealed snap-fit ​​structure between the outer shell 2 and the sealing plate 3, combined with the snap-fit ​​fixing method of the support plate 5, further optimizes the pressure release path. This innovative structural design fundamentally overcomes the technical bottleneck of earcup damage caused by the lack of pressure relief function in traditional headphones, providing a completely new solution for improving the performance of over-ear headphones.

[0027] There is at least one connecting hole 23, which is arranged in a ring array in the outer shell 2. This design can better and more efficiently release pressure. The number of connecting holes 23 is the same as the number of connecting pipes 51. By opening the connecting holes 23 in the outer shell 2 in a ring array, a multi-channel, balanced pressure release system is constructed and relatively connected in a sealed manner, so that there is no possibility of air leakage.

[0028] The outer casing 2 is provided with a connecting plate 21, which serves to connect the support plate 5 and the sealing plate 3. It is used to fasten and connect with the sealing plate 3. In addition, the connecting plate 21 on the outer casing 2 adopts a fastening connection method, which not only achieves a stable connection between the support plate 5 and the sealing plate 3, but also forms a precise positioning and sealing mechanism between the two.

[0029] The support plate 5 has a hollow connecting pipe 51, which is connected to the connecting hole 23 to ensure that airflow can enter the connecting hole 23 and then be discharged to the rear compartment through the connecting pipe 51. This design allows the airflow in the rear compartment and the wearing force to generate a reaction force, which provides some protection for the diaphragm on the speaker 4. It also has the effect of connecting the front compartment and the rear compartment to communicate with each other after the connecting pipe 51 and the connecting hole 23 are connected, increasing the volume of the rear compartment. The outer dimension of the connecting pipe 51 matches the inner dimension of the connecting hole 23, and the inner dimension of the connecting pipe 51 matches the outer dimension of the insertion hole 22. This design ensures that the connecting pipe 51 can be perfectly sealed with the connecting hole 23, ensuring that the airflow will not leak out and affect the diaphragm. The support plate 5 is located in the connecting plate 21, and the connecting plate 21 is also snapped onto the support plate 5.

[0030] The outer side of the hollow connecting tube 51 on the support plate 5 matches the inner side of the connecting hole 23 on the outer shell 2, and the inner side matches the outer side of the insertion hole 22. This dimensional adaptation achieves a sealed connection with the connecting hole 23. The collected pressurized airflow from the front chamber is introduced into the connecting tube 51 through the connecting hole 23 and discharged to the rear chamber through the hollow channel of the connecting tube 51. This structure connects the front and rear chambers through the connecting tube 51, expanding the rear chamber volume while indirectly buffering the impact on the diaphragm of the horn 4 using the reaction force generated by the airflow and wearing pressure in the rear chamber. The support plate 5 is fixed by the connecting plate 21, ensuring a stable connection position between the connecting tube 51 and the connecting hole 23, preventing seal failure due to component displacement, and completing the dual functions of pressure release and diaphragm protection through structural linkage.

[0031] When using the new type of automatic pressure-releasing headphones, the earcups 1 contact the head to form a front chamber. The pressure of the head compresses the air in the front chamber, and the pressure is discharged outward through the connection hole 23. The compressed airflow can enter the connection hole 23 evenly and efficiently.

[0032] The outer dimension of the connecting tube 51 on the support plate 5 matches the inner dimension of the connecting hole 23, and the inner dimension matches the outer dimension of the insertion hole 22, forming a sealed mating structure. This guides airflow from the connecting hole 23 through the hollow channel of the connecting tube 51 into the rear chamber composed of the sealing plate 3 and the support plate 5. The outer shell 2 is not sealed to the sealing plate 3, providing an exhaust channel for the rear chamber. This allows the pressure in the front chamber to be released through airflow, preventing the ear tips 1 from breaking due to long-term pressure.

[0033] Meanwhile, the connecting pipe 51 connects the front and rear compartments, expanding the rear compartment volume and utilizing the reaction force generated by the airflow and wearing pressure in the rear compartment to buffer the impact on the diaphragm of the speaker 4, preventing the airflow from directly acting on the diaphragm and causing deformation, abnormal noise, and a decrease in noise reduction performance. The support plate 5 is fixed by the connecting plate 21, ensuring the stable docking position of the connecting pipe 51 and the connecting hole 23, maintaining the sealing performance, and completing the dual functions of pressure release and sound quality protection in the structural linkage.

[0034] 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.
