Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically to an adjustable headphone rear cavity structure. Background Technology

[0002] With the continuous advancement of technology, electronic products with audio playback functions are becoming increasingly popular. In order to allow users to listen to the sound played by electronic products without external interference or disturbing others, headphones have become an essential accessory for electronic products.

[0003] Headphones are divided into wireless and wired headphones. Wireless headphones are mostly Bluetooth headphones. Bluetooth headphones on the market generally adjust the sound effect by using filters in the Bluetooth chip. This method has drawbacks; adjusting only through filters can make the sound harsh and unnatural. Wired headphones, on the other hand, only have a single frequency response characteristic. A single headphone can only provide a single timbre and frequency response characteristic, which can only give people one auditory experience and cannot satisfy consumers' preferences for various music styles. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a reasonably designed, replaceable, and adjustable headphone rear cavity structure that allows for sound effect adjustment through physical properties.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] An adjustable headphone rear cavity structure includes an headphone cavity, several sleeves, and an air damping mesh disposed on the sleeves. The mesh count of the air damping mesh on each sleeve is different. The headphone cavity is provided with a tuning hole. The sleeves are detachably disposed on the tuning hole and the tuning hole is blocked by the air damping mesh.

[0007] As a preferred embodiment of this utility model, the earphone cavity is provided with a vertical cylinder at the edge of the tuning hole, the air damping mesh is disposed at the upper end of the sleeve, and the lower end of the sleeve is sleeved on the vertical cylinder, which facilitates installation and disassembly.

[0008] In a preferred embodiment of this invention, the inner edge of the upper opening of the sleeve is recessed to form a mounting position that matches the shape of the air damping mesh. The air damping mesh is then adhered to this mounting position using adhesive. By utilizing the fit between the mounting position and the shape of the air damping mesh, along with the adhesive bonding, the air damping mesh can be securely installed on the sleeve, ensuring it will not easily fall off or shift during use, thus guaranteeing the stability and reliability of the air damping mesh during tuning.

[0009] As a preferred embodiment of this utility model, the air damping mesh is a nylon mesh, which has a certain strength and toughness, is not easily damaged, and can withstand the impact of sound vibration. At the same time, its mesh structure can effectively dampen airflow, thereby achieving the adjustment of sound frequency response characteristics.

[0010] In a preferred embodiment of this invention, the mesh size of the air damping mesh is 100-600 meshes. Within this mesh size range, consumers are provided with a variety of sound effect adjustment options. Different mesh sizes correspond to different air damping effects; that is, the larger the mesh size, the greater the resistance encountered by the air as it passes through, and the more significant the attenuation effect on the high-frequency part of the sound. This allows for adjustment and control of different frequency bands of the sound, enabling the headphones to present a variety of different sound effect styles, greatly enriching the sound quality performance and applicability of the headphones, and satisfying the preferences and needs of different users for different music styles.

[0011] In a preferred embodiment of this invention, five sockets are provided, with the air damping mesh on each socket having mesh counts of 100, 250, 300, 530, and 600 mesh, respectively. These five sockets offer different damping effects, each corresponding to a different sound effect adjustment scheme, further enriching the headphone's sound effect adjustment range and selectivity. This provides users with a more personalized sound quality experience. Users can choose the appropriate socket for installation based on their preferences and the style of music they are currently listening to, better meeting the listening needs of different scenarios and music genres, thereby achieving a diversified sound effect experience and enhancing the product's competitiveness and appeal.

[0012] The beneficial effects of this utility model are as follows: The utility model has a reasonable structural design, equipped with multiple sockets, each with an air damping mesh of different mesh counts. The sockets are detachably mounted on the tuning hole, and the air damping meshes block the tuning hole. When sound is transmitted through the tuning hole, the air damping meshes with different mesh counts create different resistances to airflow, thereby altering the frequency response characteristics of the sound. This physical property allows for sound effect adjustment, making the sound richer and more natural. In use, consumers can change the device themselves, selecting their preferred headphone style. By changing the sockets with different mesh counts, the headphones offer multiple sound effect adjustment possibilities, satisfying consumers' preferences for different music styles, improving the headphone's sound quality and applicability. It can be used for tuning both wireless Bluetooth headphones and wired headphones.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] See Figures 1 to 5 This embodiment provides an adjustable headphone rear cavity structure, which includes an headphone cavity 1, several sleeves 2, and an air damping mesh 3 disposed on each sleeve 2. The mesh count of the air damping mesh 3 on each sleeve 2 is different. The air damping mesh 3 is preferably a nylon mesh, which has a certain strength and toughness, is not easily damaged, and can withstand the impact of sound vibration. At the same time, its mesh structure can effectively dampen airflow, thereby achieving adjustment of the sound frequency response characteristics. The mesh count of the air damping mesh 3 is preferably 100 to 600 meshes. Within the mesh count range of 100 to 600 meshes, consumers are provided with a variety of sound effect adjustment options. Different mesh counts correspond to different air damping effects. That is, the larger the mesh count, the greater the resistance encountered by the air when passing through, and the more obvious the attenuation effect on the high-frequency part of the sound. This enables adjustment and control of different frequency bands of the sound, allowing the headphones to present a variety of different sound effect styles, greatly enriching the sound quality performance and applicability of the headphones, and meeting the preferences and needs of different users for different music styles.

[0020] In this embodiment, five socket tubes 2 are used as an example. That is, there are five socket tubes 2, and the mesh size of the air damping mesh 3 on each socket tube 2 is 100 mesh, 250 mesh, 300 mesh, 530 mesh, and 600 mesh, respectively. Five socket tubes 2 with different damping effects are provided, each corresponding to a different sound effect adjustment scheme, further enriching the sound effect adjustment range and selectivity of the headphones, providing users with a more personalized sound quality experience. Users can choose the appropriate socket tube 2 to install according to their preferences and the style of music they are currently listening to, which can better meet the listening needs of different scenarios and different music types, thereby achieving a diversified sound effect experience and enhancing the product's competitiveness and attractiveness. In other embodiments, the number of socket tubes 2 and air damping mesh 3 can be configured according to the required sound effect, such as three, four, six, or more socket tubes 2.

[0021] The air damping mesh 3 is disposed at the upper end of the sleeve 2. Specifically, an assembly position 21 is formed by a recess in the inner edge of the upper opening of the sleeve 2, which is adapted to the shape of the air damping mesh 3. The air damping mesh 3 is adhered to the assembly position 21 by adhesive. By utilizing the fit between the assembly position 21 and the shape of the air damping mesh 3, and with the adhesive backing for fixation, the air damping mesh 3 can be firmly installed on the sleeve 2, ensuring that it will not easily fall off or shift during use, thus guaranteeing the stability and reliability of the air damping mesh 3 during the tuning process.

[0022] The earphone housing 1 is provided with a tuning hole 11. Preferably, a vertical cylinder 4 is provided on the earphone housing 1 at the edge of the tuning hole 11. The vertical cylinder 4 can be integrally injection molded with the earphone housing 1, or it can be fixed by adhesive. The lower end of the sleeve 2 is sleeved on the vertical cylinder 4, that is, the sleeve 2 is assembled on the vertical cylinder 4 by interference fit, so that the sleeve 2 can be detachably set on the tuning hole 11, and then the tuning hole 11 is blocked by the air damping mesh 3 located at the upper end of the sleeve 2.

[0023] In other embodiments, the vertical cylinder 4 may be omitted. The tuning hole 11 is adapted to the size of the sleeve 2, that is, the lower end of the sleeve 2 can be directly inserted into the tuning hole 11. The sleeve 2 is also detachably assembled onto the tuning hole 11 through an interference fit. The installation and disassembly process is convenient.

[0024] In use, this utility model is equipped with five socket sleeves 2, each with a different mesh size of air damping mesh 3: 100 mesh, 250 mesh, 300 mesh, 530 mesh, and 600 mesh. Consumers can easily change the device to select their preferred headphone style by replacing the socket sleeves 2 with different mesh sizes.

[0025] See Figure 5 The headphones are shipped with a socket 2 equipped with a 300-mesh air damping mesh 3 in the factory configuration. Selecting the socket 2 with the 300-mesh air damping mesh 3 activates the headphone bass enhancement level 1. Selecting the socket 2 with the 300-mesh air damping mesh 3 also activates the headphone bass enhancement level 1. Selecting the socket 2 with the 250-mesh air damping mesh 3 activates the headphone bass enhancement level 1. Selecting the socket 2 with the 530-mesh air damping mesh 3 activates the headphone pure mode level 1. Selecting the socket 2 with the 600-mesh air damping mesh 3 activates the headphone pure mode level 2. By utilizing the air damping mesh 3 with different mesh counts, different resistances are created to airflow, thereby altering the frequency response characteristics of the sound. This achieves sound effect adjustment through physical properties, resulting in a richer and more natural sound. The headphones offer multiple sound effect adjustment possibilities to meet consumers' preferences for different music styles.
