Description

Technical Field

[0001] This utility model relates to the field of volume key technology, and in particular to a volume key structure and a headset. Background Technology

[0002] Headphone volume buttons refer to the buttons or controls on headphones used to adjust the volume. These buttons are usually located in the headphone in-line controls, close to the headphones. Users can increase the volume by clicking the volume "+" button and decrease the volume by clicking the volume "-" button.

[0003] Some headphone volume buttons on the market achieve their rebound through the spring force of the volume switch or by adding an additional spring. Since the rebound force of the volume switch is limited, the volume buttons may experience looseness, rattling noises, or failure to rebound promptly. Adding an additional spring, on the other hand, complicates assembly and increases costs.

[0004] For example, Chinese patent application CN201220514231.0 discloses a Bluetooth headset, specifically stating "a Bluetooth headset, including a mid-frame, a circuit board installed in the cavity of the mid-frame, a front shell and a bottom shell respectively snapped onto the upper and lower surfaces of the mid-frame, and an earpiece extending from the bottom shell, wherein the front shell is an elastic body with a protrusion on its inner side, the protrusion triggering a headset switch provided on the circuit board." "A rectangular groove is provided on one side wall of the mid-frame, a volume button is installed in the rectangular groove, and a rib extends from the bottom shell at the volume button position to hold the volume button in place." The volume button of this type of headset can only be activated by a volume switch or by an additional spring, which suffers from the aforementioned problem. Utility Model Content

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] Example 1

[0033] Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a volume key structure.

[0034] The button 30 has an elastic seat 312, which provides sufficient elasticity to prevent the button 30 from loosening or making abnormal noise after assembly. Simultaneously, the button 30 can swing on the support 11, which disperses the impact force on the button 30 and prevents damage.

[0035] This application provides a volume key structure, including a first shell 10, a second shell 20, and a button 30. The button 30 has a groove 31. The first shell 10 and the second shell 20 are fitted together. A support portion 11 is provided inside the first shell 10, and the support portion 11 is embedded in the groove 31. The button 30 can swing on the support portion 11. A first end of the button 30 can trigger a first volume control switch 32, and a second end of the button 30 can trigger a second volume control switch 33. An elastic seat 312 is formed on the outer periphery of the button 30. A first positioning post 21 is provided inside the second shell 20, and the first positioning post 21 passes through the elastic seat 312. The button 30 is an accessory made of metal or plastic. In this embodiment, the first shell 10, the second shell 20, and the button 30 are injection molded parts, manufactured using injection molding technology. The first shell 10 and the second shell 20 are assembled together by fastening and / or screws. The first volume control switch 32 and the second volume control switch 33 are connected to a circuit board 13. The button 30 swings on the support 11, thereby triggering either the first volume control switch 32 or the second volume control switch 33. The support 11 is embedded in the groove 31, which supports the button 30. The groove 31 and the support 11 have arc-shaped cross-sections. The groove 31 is an arc-shaped groove, and the support 11 is an arc-shaped rod. This structural design can reduce the impact force on the button 30. When the button 30 is hit at any angle, the impact force will be transmitted to the support 11, thereby protecting the button 30 and providing effective protection. The elastic seat 312 extends from the button 30. The button 30 and the elastic seat 312 are integrally formed. This structure makes the assembly structure of the button 30 simpler and easier, helping to reduce production costs. In this embodiment, the first volume control switch 32 and the second volume control switch 33 are preferably push-button electronic switches.

[0036] Preferably, the base of the button 30 extends a limiting step 310, the button 30 is exposed in the second housing 20, and the limiting step 310 is blocked by the inner wall of the second housing 20. The limiting step 310 extends from the edge of the button 30. During assembly, the button 30 is exposed in the second housing 20, and the limiting step 310 is blocked by the inner wall of the second housing 20. This design prevents the button 30 from coming out of the button 30 hole on the second housing 20, making assembly simpler.

[0037] Preferably, a limiting post 311 is provided on the limiting step 310, and the first volume control switch 32 and the second volume control switch 33 are disposed on the circuit board 13. The limiting post 311 can press against the circuit board 13. The circuit board 13 is fixed to the first housing 10 by screws. When the button 30 is pressed, the limiting post 311 presses against the edge of the circuit board 13. This design can control the swing amplitude of the button 30, and thus control the force on the first volume control switch 32 and the second volume control switch 33, effectively protecting the first volume control switch 32 and the second volume control switch 33.

[0038] Preferably, the elastic seat 312 includes a first elastic part 313, a second elastic part 314, and a third elastic part 316 connected in sequence; the first elastic part 313 and the third elastic part 316 are inclined inward; the second elastic part 314 is provided with a first mounting hole 315, and the first positioning post 21 is inserted into the first mounting hole 315. The elastic seat 312 is made of elastic plastic and can withstand a certain elastic deformation, thereby enabling the button 30 to obtain elastic force. The elastic seat 312 is frame-shaped or ring-shaped. When the first shell 10 and the second shell 20 are fastened, the first positioning post 21 is inserted into the first mounting hole 315, so that the button 30 can be positioned and will not loosen. Preferably, the first elastic part 313 and the third elastic part 316 are inclined inward, and the second elastic part 314 connects the first elastic part 313 and the third elastic part. With this design, when the button 30 is pressed, the elastic seat 312 can undergo elastic deformation, so the button 30 can obtain a good rebound force.

[0039] Preferably, the support portion 11 extends to both sides with limiting plates 12, and the groove of the recess 31 can press against the limiting plates 12. This allows the limiting plates 12 to block the button 30 when it swings to a certain extent, thus limiting the swing range of the button 30 and protecting the first volume control switch 32 and the second volume control switch 33.

[0040] Preferably, a first acoustic cavity 15 is formed by a recess on the first shell 10, and an ear pad 18 is provided at the opening of the first acoustic cavity 15. The first acoustic cavity 15 is formed by a recess, and the ear pad 18 is provided at the opening of the first acoustic cavity 15, which increases the depth of the first acoustic cavity 15, provides more space to accommodate the outer ear, and makes the sound outlet further away from the eardrum, greatly improving the wearing comfort.

[0041] Preferably, the first shell 10 is provided with a first fastening part 14, and the ear pad 18 is sleeved on the mounting frame 16. The mounting frame 16 is provided with a second fastening part 17; the second fastening part 17 fastens to the first fastening part 14. The ear pad 18 can be sleeved or glued to the mounting frame 16. The second fastening part 17 is an L-shaped barb, and the first fastening part 14 is block-shaped. The second fastening part 17 fastens to the first fastening part 14. This design makes the assembly of the ear pad 18 very convenient and efficient.

[0042] Example 2

[0043] Please refer to Figure 9 As shown, this application provides a headset including the aforementioned volume button structure; an earcup 41 is rotatably mounted on the end of the headband 40, and a second shell 20 is pivotally mounted on the earcup 41. The earcup 41 is an injection-molded part. The headband 40 and the earcup 41 are rotatably connected via a first connecting shaft. A second connecting shaft is provided on the earcup 41, and the earcup 41 is rotatably connected to the second shell 20 support via a second connecting shaft 42. This design allows the headset to fit snugly against the ear for better comfort.

[0044] In summary, the key design feature of this invention is that the elastic seat 312 on the outer periphery of the button 30 provides elasticity to the button 30. The button 30 generates elasticity through its own structure, resulting in better rebound force and eliminating looseness and noise. The assembly of the button 30 is also simpler and less costly. Furthermore, when the button 30 swings on the support 11, the support 11 protects the button 30, providing effective protection.
