Description

Technical Field

[0001] This application relates to the field of audio equipment technology, and more particularly to a handset structure and an audio device. Background Technology

[0002] In the design of some audio devices on the market, such as headphones, over-ear headphones, and over-ear dual-channel hearing aids, the earpiece shell is usually made of plastic. For example, in some over-ear headphones, the earpiece often needs to be pressed against the ear, causing the plastic shell to come into direct contact with the skin of the ear.

[0003] Existing earpiece shells use rigid plastic components to ensure the structural strength of the earpiece, but the hard inner surface of the shell is close to the skin, causing rigid compression and resulting in discomfort for the user.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a handset structure and an audio device to solve the problem that the handset shell in the prior art is relatively hard, resulting in uncomfortable wearing.

[0006] The technical solution of this application is as follows: This application proposes a handset structure, including: a handset housing, an audio component disposed inside the handset housing, the handset housing having an inner sidewall facing the user's ear, and a sound outlet hole opened on the inner sidewall of the handset. A soft covering layer covers the surface of the inner wall of the earpiece.

[0007] Optionally, a sound-emitting protrusion is provided on the inner wall of the earpiece, and the sound outlet is opened on the sound-emitting protrusion; The soft covering layer includes a soft protrusion with an opening for ventilation. The soft protrusion covers the sound-emitting protrusion, and the sound outlet is located inside the opening for ventilation.

[0008] Optionally, a speaker grille is provided on the sound-emitting protrusion, and the speaker grille covers the sound-emitting hole; An inner baffle is provided at the opening of the air-proof opening. The inner diameter of the inner baffle is smaller than the outer diameter of the speaker mesh, and the inner baffle covers the edge of the speaker mesh. Optionally, the inner edge protrudes to form a raised top, which protrudes a predetermined length toward the user's ear to form a sound outlet channel with an axial length.

[0009] Optionally, a mesh connector is provided on the outer periphery of the speaker mesh, and a mating position is provided on the inner shell of the earpiece. The mesh connector is embedded in the mating position so that the speaker mesh is positioned on the sound-emitting protrusion.

[0010] Optionally, the mesh connector includes a insert that is integrally formed with the speaker mesh on the edge of the speaker mesh; The mating position includes a plug hole into which a insert is inserted to connect the mesh connector to the inner wall of the earpiece.

[0011] Optionally, the insert has an insertion end facing away from the speaker grille, the insertion end gradually approaching the central axis of the speaker grille in a direction away from the speaker grille.

[0012] Optionally, the sound-emitting protrusion is inclined on the surface of the inner wall of the earpiece, so as to face the user's ear canal opening.

[0013] Optionally, the top of the sound-emitting protrusion has a sound-emitting plane, and a sound-emitting angle is formed between the sound-emitting plane and the base surface of the inner wall of the earpiece, the sound-emitting angle being greater than 0 degrees and less than or equal to 90 degrees.

[0014] Optionally, the soft covering layer is a silicone layer or an engineered soft rubber layer.

[0015] Optionally, the earpiece housing includes: an earpiece front cover and an earpiece inner cover, the earpiece front cover having a rear sound cavity hole, and the earpiece inner wall located on the earpiece inner cover.

[0016] On the other hand, this application also proposes an audio device, which includes two earpiece structures as described above, two main units, and a rear-mounted unit; The earpiece is connected to the main unit, and the two main units are connected via a rear-mounted connector.

[0017] The beneficial effects of the earpiece structure and audio device provided in this application are at least as follows: by providing a soft covering layer on the surface of the inner wall of the earpiece housing, when the earpiece is hung on the user's ear, the soft covering layer on the inner surface contacts the skin of the ear. Since the soft covering layer is easy to deform, it makes soft contact with the skin, thereby improving wearing comfort. Attached Figure Description

[0023] like Figure 1 , Figure 2As shown, this embodiment proposes an earpiece structure for use in audio devices such as in-ear headphones, over-ear headphones, and over-ear dual-channel hearing aids. This earpiece structure mainly includes an earpiece housing 100 and a soft covering layer 200. An audio component 400 is disposed within the earpiece housing 100 for playing audio. The earpiece housing 100 has an inner earpiece wall 121 facing the user's ear and an outer earpiece wall facing away from the user's ear. A sound outlet 130 is provided on the inner earpiece wall 121, through which the sound played by the audio component 400 is transmitted to the user's ear. The soft covering layer 200 covers the surface of the inner earpiece wall 121. The soft covering layer 200 is a silicone layer or an engineering soft rubber layer, formed by secondary injection molding using silicone, TPU, TPE, or TPR materials, thereby covering the surface of the inner earpiece wall 121. By providing a soft covering layer 200 on the surface of the inner wall 121 of the earpiece housing 100, when the earpiece is hung on the user's ear, the soft covering layer 200 on the inner surface comes into contact with the skin of the ear. Since the soft covering layer 200 is easy to deform, it makes soft contact with the skin, thereby improving wearing comfort.

[0024] like Figure 1 , Figure 2 As shown, in the specific structure, the earpiece housing 100 may include an earpiece front cover 110 and an earpiece inner cover 120. The earpiece front cover 110 and the earpiece inner cover 120 are spliced ​​and assembled to form the earpiece housing 100 (a rigid plastic housing), and the audio components 400 are fixed inside it. The outer surface of the earpiece inner cover 120 is the earpiece inner wall 121, and a soft covering layer 200 covers the earpiece inner wall 121. The shape of the soft covering layer 200 is flush with the edge of the earpiece front cover 110 and connects with it, thereby ensuring the overall smoothness of the appearance. For example, a recessed area is provided on the surface of the inner earpiece cover 120 (or when the earpiece face cover 110 and the inner earpiece cover 120 are assembled, the edge of the earpiece face cover 110 will protrude from the edge of the inner earpiece cover 120, thus forming the recessed area). The soft covering layer covers the recessed area and does not protrude outward from the edge of the earpiece face cover, so that the shape of the inner soft covering layer is flush with the edge of the earpiece face cover and connected, thereby ensuring the overall smoothness of the appearance.

[0025] like Figure 2 , Figure 3As shown, a sound-emitting protrusion 122 is further provided on the inner wall 121 of the earpiece, and a sound-emitting hole 130 is formed on the end face of the sound-emitting protrusion 122. The sound-emitting protrusion 122 protrudes towards the user's ear. The soft covering layer 200 includes a soft protrusion 210, on which a clearance opening 220 is formed. The soft protrusion 210 covers the sound-emitting protrusion 122, and the sound-emitting hole 130 is located within the clearance opening 220. By making the sound-emitting hole 130 protrude and closer to the ear canal opening, not only can the sound be guided into the ear, resulting in a better sound output effect, but also the soft covering layer 200 is more firmly fixed to the sound-emitting protrusion 122 by the soft protrusion 210 surrounding the sound-emitting protrusion 122, thus improving the fixation firmness of the soft covering layer 200.

[0026] like Figure 2 , Figure 3 As shown, a speaker grille 300 is provided on the sound-emitting protrusion 122, covering the sound outlet 130. An inner baffle 221 is provided at the opening of the clearance 220. The inner diameter of the inner baffle 221 is smaller than the outer diameter of the speaker grille 300, thus forming a step at the end of the soft protrusion 210 through the inner baffle 221, resulting in a stepped hole at the clearance 220 where the soft protrusion 210 is larger on the inside and smaller on the outside. The inner baffle 221 covers the edge of the speaker grille 300, pressing the speaker grille 300 against the end face of the sound-emitting protrusion 122, achieving stable fixation of the speaker grille 300 and preventing it from slipping out of the clearance 220.

[0027] The inner baffle 221 protrudes towards the sound outlet direction, forming a raised top 222. This raised top 222 increases the thickness of the inner baffle 221, thus making the speaker grille 300 more securely fixed by the inner baffle 221. Furthermore, the raised top 222 protrudes towards the user's ear, creating an inclined sound outlet channel with axial length. This channel guides the sound output direction, achieving directional sound transmission towards the user's ear. The end of the raised top 222 is positioned close to the ear canal opening, effectively reducing sound reflection within the concha and improving sound output performance.

[0028] like Figure 2 , Figure 3 As shown, a mesh connector 310 is provided on the outer periphery of the speaker grille 300, and a mating position 123 is provided on the inner shell of the earpiece. The mesh connector 310 is embedded in the mating position 123 so that the speaker grille 300 is positioned on the sound outlet protrusion 122. Before the secondary injection molding of the soft covering layer 200, the mesh connector 310 is first connected to the mating position 123, so that the speaker grille 300 is first limited on the sound outlet protrusion 122, avoiding displacement of the speaker grille 300 due to the impact of the injection plastic during the secondary injection molding process, improving the stability of the secondary injection molding process and increasing the yield.

[0029] like Figure 2 , Figure 3 As shown, the mesh connector 310 in this embodiment includes a insert 311, which is integrally formed with the speaker grille 300 on its edge. The corresponding mating position 123 includes a insertion hole 124, into which the insert 311 is inserted to connect the mesh connector 310 to the inner wall 121 of the earpiece. The insert 311 can be a single piece extending a predetermined length axially. A insert 311 of a certain length can be fully inserted into the insertion hole 124, and can only be dislodged when it bends away from the insertion hole 124. Therefore, the use of the insert 311 to engage with the insertion hole 124 reduces the risk of the mesh connector 310 detaching from the sound outlet protrusion 122 after installation. In other structures, the mesh connector 310 can also be a hook, a tooth, etc., and the corresponding mating position 123 can be a buckle, a groove, etc.

[0030] like Figure 2 , Figure 3 As shown, the insert 311 has an insertion end 312 facing away from the speaker grille 300. Guide slopes 313 are provided on both sides of the insertion end 312, forming a conical structure. This facilitates insertion into the insertion hole 124 during assembly, improving assembly efficiency. The insertion end 312 gradually approaches the central axis of the speaker grille 300 in a direction away from the speaker grille 300, causing the insert 311 to be tilted inwards. A flexible clamping opening 314 is formed between the insert 311 and the speaker grille 300. When the insert 311 is inserted into the insertion hole 124, it is pushed away from the speaker grille 300 by the pressure of the sound-emitting protrusion 122, causing the clamping opening 314 to open and generate a clamping force. This clamping force allows the speaker grille 300 to adhere to the end face of the sound-emitting protrusion 122, preventing it from easily detaching from the insertion hole 124 of the sound-emitting protrusion 122.

[0031] like Figure 3 , Figure 4 As shown, the sound-emitting protrusion 122 is further inclined on the surface of the inner wall 121 of the earpiece, facing the user's ear canal opening. By tilting the sound-emitting protrusion 122, the sound outlet faces the ear canal opening and is closer to it, avoiding excessive loss of the audio signal emitted from the sound outlet. When the earpiece is used at the user's ear, the longitudinal section of the earpiece housing 100 is the base surface of the inner wall 121, and the top end face of the sound-emitting protrusion 122 is the sound-emitting plane 131, which gradually moves away from the ear canal opening from top to bottom. Figure 4 As shown, a sound-emitting angle α is formed between the sound-emitting plane 131 and the base plane of the inner wall 121 of the earpiece. The sound-emitting angle α is greater than 0 degrees and less than or equal to 90 degrees. Specifically, the best effect can be achieved within the range of 15°-70°.

[0032] like Figure 1 , Figure 2 As shown, in the above structure, the sound outlet is tilted to achieve open sound transmission, which is beneficial for directional sound transmission, reduces the distance from the sound outlet to the ear canal opening, and reduces sound reflection within the concha. In particular, the soft protrusion 210 covers the outer surface of the protruding sound outlet protrusion 122, making it more comfortable to wear.

[0033] Furthermore, the earpiece cover 110 can be designed as an independent structural component, manufactured separately and then assembled later. For example, it can be assembled as an independent structural component onto the main unit 500, or onto the curved connecting section 510 connected to the main unit 500. Independent design allows for greater flexibility in its shape design, less constraint by manufacturing processes, and facilitates assembly and industrial design.

[0034] like Figure 2 As shown, a rear acoustic chamber hole 111 is provided on the earpiece cover 110. The rear acoustic chamber hole 111 can be crescent-shaped or other relatively large opening structures. A dustproof mesh 112 is provided on the inside of the earpiece cover 110 to cover the rear acoustic chamber hole 111. Better sound quality can be achieved through the rear acoustic chamber hole 111.

[0035] like Figure 1 As shown, at least one button 113, such as a volume control button, can be designed on the earpiece housing 100. A call pickup hole is also provided on the earpiece housing 100 for convenient reception of the user's voice.

[0036] Example 2 like Figure 5 As shown, this application also proposes an audio device, including two earpiece structures as described above, two main units 500, and a rear hook 600. The earpiece structures are connected to the main units 500, and the two main units 500 are connected via the rear hook. The earpiece structures and the main units 500 can be connected via a flexible connecting section 510, which can deform to adapt to the user's usage habits; for example, it can be made of shape memory metal. The rear hook 600 can also be bent and deformed to adapt to the user's usage habits.

[0037] Both the curved connecting section 510 and the rear hanger 600 are equipped with conductive connectors for providing power or signals. These conductive connectors can be flexible circuit boards or cables. Multiple conductive connectors connect the left earpiece structure to the left main unit 500, the right earpiece structure to the right main unit 500, and the left and right main units 500, thus enabling audio playback functionality.

[0038] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
