Description

Technical Field

[0001] This utility model relates to the field of sound unit technology, specifically to an earphone. Background Technology

[0002] Currently, traditional headphones primarily transmit sound through air conduction or bone conduction. Air conduction headphones rely on speakers to drive air vibrations, but they suffer from sound leakage and their sound quality is easily affected by noise. While bone conduction headphones reduce sound leakage, they are less comfortable to wear and may cause ear fatigue with prolonged use. Furthermore, the vibrator assembly in existing headphones is usually built into the shell, resulting in lower vibration transmission efficiency and consequently, insufficient sound clarity and low-frequency performance.

[0003] To address these issues, some improvement solutions have attempted to optimize the vibrator layout or adopt a structure that fits the ear, but problems such as indirect vibration transmission paths and poor fit still exist. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a headphone that is compact in structure, efficient in vibration transmission, comfortable to wear and easy to assemble.

[0005] This utility model is achieved through the following technical solution: An earphone includes a housing, a conductive component, and a vibrator assembly installed within the housing, wherein the output end of the vibrator assembly protrudes from the housing; the conductive component includes a connecting portion and a wearing portion, wherein the shape of the wearing portion is adapted to the shape of the concha of the human ear, and the output end of the vibrator assembly is connected to the wearing portion through the connecting portion to achieve vibration transmission.

[0006] The oscillator assembly includes an oscillator support and an oscillator body mounted on the oscillator support; The lower end of the vibrator bracket is connected to a drive shaft, which is connected to the wearing part through a connecting part.

[0007] The oscillator support has an open top, and the oscillator body is installed inside the oscillator support.

[0008] The oscillator support, oscillator body, and drive shaft are integrally formed.

[0009] The drive shaft has a groove at its end that is parallel to the radial direction of the drive shaft, and the connecting part has a boss that mates with the groove.

[0010] The cross-section of the groove is arc-shaped or semi-circular.

[0011] The drive shaft has a foolproof surface on one side, and the connecting part has a fixing surface that fits against the foolproof surface.

[0012] The housing includes an upper cover, a middle shell, and a lower shell connected sequentially from top to bottom. The inner end face of the upper cover is provided with several reinforcing ribs, which press against the upper end face of the oscillator assembly.

[0013] A gasket is connected between the vibrator support and the housing, and the drive shaft protrudes from the gasket and connects to the connecting part.

[0014] The conductive component further includes an ear wing disposed between the connecting part and the wearing part, wherein the connecting part, the wearing part, and the ear wing are detachably connected; Positioning parts for limiting axial rotation are provided between the connecting part and the wearing part, and between the wearing part and the ear wing.

[0015] The beneficial effects of this utility model are: The headphones provided by this utility model adopt a design in which the vibrator assembly and the conduction assembly are separated but physically connected. The vibration generated by the vibrator is directly transmitted to the concha cavity of the human body through the conduction assembly. The sound signal is transmitted to the auditory nerve by utilizing the conduction principle of the auricular cartilage, effectively bypassing the ear canal and eardrum. This avoids the pressure and blockage feeling of traditional in-ear headphones on the ear canal, making them comfortable to wear and not affecting the user's perception of ambient sound, thus improving the safety and comfort of use. In addition, the connection of the vibrator bracket, drive shaft and conduction assembly forms an efficient and stable vibration transmission path, which can minimize energy loss and ensure that the vibration energy generated by the vibrator is effectively and accurately transmitted to the wearing part, thereby improving the sound quality and conduction efficiency of the headphones.

Detailed Implementation

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] Example 1 like Figures 1 to 4 As shown, the earphone of this utility model mainly includes a housing 100, a vibrator assembly 300, and a conduction assembly 200. The vibrator assembly 300 is installed inside the housing 100, and its output end protrudes outside the housing 100. The conduction assembly 200 is used to transmit the vibration generated by the vibrator assembly 300 to the human ear.

[0026] In this embodiment, the conduction component 200 includes a connecting portion 201 and a wearing portion 202. The wearing portion 202 is designed to conform to the shape of the human concha, allowing it to fit snugly against the concha during wear, thereby achieving optimal vibration conduction. The output end of the vibrator component 300 is securely connected to the wearing portion 202 via the connecting portion 201, enabling lossless transmission of vibration from the vibrator component 300 to the wearing portion 202. After the vibration is conducted to the concha by the wearing portion 202, it is conducted through the auricular cartilage, directly reaching the inner ear and bypassing the tympanic membrane, thus achieving a clear auditory experience. Because the ear canal is not blocked, the user can clearly hear ambient sounds, greatly enhancing safety for outdoor use.

[0027] In this embodiment, the vibrator assembly 300 specifically includes a vibrator support 301 and a vibrator body 302 installed within the vibrator support 301. The vibrator body 302 is the core component that generates vibration, and its vibration energy is collected and transmitted through the vibrator support 301. A drive shaft 303 (the output end of the vibrator assembly 300) is connected to the lower end of the vibrator support 301. This drive shaft 303 acts as a key mechanical connector between the vibrator assembly 300 and the conduction assembly 200, ensuring that vibration can be transmitted to the connection part 201 in the most direct and concentrated manner, and then transmitted from the connection part 201 to the wearing part 202. This design greatly reduces energy loss during vibration transmission and improves overall conduction efficiency and sound quality performance.

[0028] In this embodiment, the oscillator support 301 has an open top, and the oscillator body 302 is installed inside the oscillator support 301. This design makes the installation and positioning of the oscillator body 302 simple and reliable. At the same time, the oscillator support 301 can provide stable support for the oscillator body 302, ensuring that it will not shift or loosen during vibration, and further ensuring the stability and consistency of vibration transmission.

[0029] To ensure a secure connection between the connecting part 201 and the drive shaft 303 without relative rotation, the end of the drive shaft 303 has a parallel groove 304 along its radial direction. Correspondingly, the connecting part 201 has a boss 203 that mates with the groove 304. When the connecting part 201 is connected to the drive shaft 303, the boss 203 will engage with the groove 304, achieving a secure lock. This structure effectively prevents axial rotation of the connecting part 201, ensuring the correct orientation of the wearing part 202, thereby achieving the best wearing fit. The cross-section of the groove 304 can preferably be arc-shaped or semi-circular; this design makes the connection smoother and stronger, and reduces stress concentration.

[0030] Furthermore, to prevent incorrect orientation of the connecting part 201 and the drive shaft 303 during assembly, a foolproof surface 305 is provided on one side of the drive shaft 303 in this embodiment, and a corresponding fixing surface 204 that fits against the foolproof surface 305 is provided at the connection point of the connecting part 201. Only when the connecting part 201 is aligned correctly with the drive shaft 303 can the two be successfully connected. This foolproof design greatly simplifies user operation, prevents damage caused by incorrect assembly, and improves product reliability.

[0031] In terms of the structure of the housing 100, it can be composed of an upper cover 101, a middle shell 102, and a lower shell 103 connected sequentially from top to bottom. To ensure the stability of the oscillator assembly 300 inside the housing 100, the inner end face of the upper cover 101 can be provided with several reinforcing ribs, which can tightly press against the upper end face of the oscillator assembly 300. This design utilizes the closed structure of the housing 100 to form a two-way constraint on the oscillator assembly 300, ensuring that its position inside the housing 100 will not shift due to vibration, avoiding internal abnormal noise caused by vibration, and accurately guiding the vibration energy to the drive shaft 303.

[0032] To further isolate the vibration of the oscillator assembly 300, a gasket 104 can be connected between the oscillator support 301 and the housing 100. The gasket 104 can be made of an elastic material (such as rubber, silicone, etc.), and the drive shaft 303 of the oscillator assembly 300 protrudes through the gasket 104 and connects to the connecting part 201. The function of the gasket 104 is to absorb and attenuate the stray vibrations generated by the oscillator assembly 300 during operation, prevent these vibrations from being transmitted to the housing 100, thereby eliminating the noise generated by the vibration of the housing 100, and making the vibration energy more concentrated on the conduction component 200, thus improving the sound quality purity of the headphones.

[0033] To meet the wearing needs of different users, the conductive component 200 can also be modular. For example, it may further include an ear wing 205 disposed between the connecting part 201 and the wearing part 202. The connecting part 201, the wearing part 202, and the ear wing 205 can be designed to be detachably connected. For example, positioning parts for limiting axial rotation are provided between the connecting part 201 and the wearing part 202, and between the wearing part 202 and the ear wing 205, to ensure that each component maintains its correct relative position after disassembly and assembly. This modular design allows users to freely replace the wearing part 202 and the ear wing 205 of different sizes according to their ear size and wearing habits, improving the product's versatility and user experience.

[0034] Example 2 To further simplify manufacturing and improve the reliability of vibration transmission, the oscillator support 301, oscillator body 302, and drive shaft 303 can be designed as a single integrated structure. For example, these three components can be manufactured in one piece using integrated injection molding technology. This integrated design not only eliminates gaps between components, avoiding vibration attenuation caused by weak connections, but also significantly reduces production costs and assembly time.

[0035] It should be noted that, except for the content described in this embodiment, all other contents are the same as in Embodiment 1, and will not be repeated here.

[0036] In summary, the headphones provided by this utility model, through the above-mentioned structural design, not only solve the pain points of existing headphones in terms of wearing comfort and safety, but also achieve efficient and stable performance by optimizing the vibration transmission path and connection method. At the same time, they also show unique advantages in manufacturing and assembly, making them an innovative audio product with high comfort, high safety, high conduction efficiency and high reliability.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
