Description

Technical Field

[0001] This utility model belongs to the technical field of headphone products, specifically relating to a volume control earcup assembly and headphones. Background Technology

[0002] Currently, in the transmission and adjustment structures of electronic devices, adjustment is typically achieved using buttons or potentiometers without stop. Traditional button adjustments cannot meet users' needs for precise, rapid, and large-amplitude volume control, and offer a limited tactile experience. Potentiometers without stop adjust volume by rotating them to change the resistance value.

[0003] However, using potentiometers as the transmission mechanism for volume adjustment has revealed numerous problems. From a durability perspective, potentiometers contain components such as sliders, coils, and spring-loaded contacts. After prolonged use, the slider contacts will wear down, the coils are prone to wear and oxidation, and the elasticity of the spring-loaded contacts will decrease. After a certain number of years of actual use, frequent malfunctions such as poor contact will occur, leading to a decline in device performance or even complete malfunction. Moreover, the brushes and resistive film of potentiometers are prone to developing "dead zones" due to mechanical wear, manufacturing tolerances, poor contact, or material aging. These dead zones are areas where the output signal does not change during adjustment, which greatly affects the accuracy of adjustment. This results in abrupt or discontinuous changes in volume adjustment, severely degrading the user experience.

[0004] In conclusion, the existing traditional dial adjustment structure and potentiometer structure can no longer meet the growing demand for high-quality electronic devices in terms of durability and adjustment accuracy. There is an urgent need to develop a new transmission adjustment structure to overcome the above-mentioned defects of potentiometers and improve the overall performance of electronic devices and user experience. Summary of the Invention

[0005] To address the shortcomings of the prior art, this invention provides a volume-adjustable earcup assembly. This earcup uses a decoder to adjust the volume, and utilizes a roller, transmission gears, and the decoder's rotational transmission to achieve precise volume adjustment, while also being durable. Furthermore, this invention also provides headphones including this volume-adjustable earcup assembly.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects: In a first aspect, this utility model provides a volume-adjustable ear cup assembly, including a first housing, a roller rotatably connected to the first housing, a transmission gear meshing with the inner side of the roller, the transmission gear having a protruding connecting portion, a rotary encoder being drivenly connected to the connecting portion, the rotary encoder having a rotating component adapted to the connecting portion, the outer side of the roller being exposed on the outer side of the volume-adjustable ear cup assembly, the roller rotating and driving the rotating component to rotate through the transmission gear, and the rotary encoder being connected to a PCB board.

[0007] In some implementations, the roller is a ring structure that is rotatably connected to the first housing.

[0008] In some implementations, the first housing is provided with a first rotating groove, and a protrusion is provided below the roller. The protrusion is located within the first rotating groove, and the roller rotates along the first rotating groove through the protrusion.

[0009] In some implementations, a second housing is also included, which is located above the roller, with the roller positioned between the first housing and the second housing in the vertical direction.

[0010] In some implementations, the outer side of the roller is provided with a number of spaced-apart paddles, and the cross-sectional shape of the paddles is an "L" structure.

[0011] In some implementations, the first housing includes a first base and a first outer ring surrounding the first base, the transmission gear is connected to the first base, and the roller is rotatably connected to the first outer ring.

[0012] In some implementations, the first base is provided with a second rotating groove, and the transmission gear is rotatably connected to the second rotating groove.

[0013] In some implementations, the second housing assembly includes a second outer ring and a second base, the PCB board is connected to the second base, and the second outer ring is provided with a stop that protrudes toward the roller and abuts against the inner side of the roller.

[0014] In some implementations, the first housing and the second housing are locked together, the second base is provided with a clearance hole, the transmission gear and the rotary encoder are limited between the first housing and the second housing, and the rotary encoder is exposed in the clearance hole to connect with the PCB board.

[0015] Secondly, this utility model provides an earphone, including a headband and the aforementioned volume-adjusting ear cup assembly, wherein the volume-adjusting ear cup assembly is connected to both sides of the headband.

[0016] In summary, this utility model has at least the following advantages: 1. This utility model provides a volume control ear cup assembly. This assembly uses a rotary encoder to achieve precise volume adjustment. It also utilizes the cooperation between a roller, a transmission gear, and the rotary encoder to achieve precise adjustment. Because the roller and transmission gear are meshed, they have a precise tooth structure. This precise tooth structure, combined with the rotary encoder, allows for accurate adjustment of the appropriate volume level. Furthermore, the tight cooperation between the roller, transmission gear, and rotary encoder enables precise volume adjustment within a small space. Additionally, the gear engagement provides clear physical feedback, such as tooth feel and damping, allowing users to quickly perform blind operation based on muscle memory. Gear structures typically possess high strength and stability, capable of withstanding frequent rotation and use. Therefore, compared to traditional potentiometers, this gear-operated rotary encoder offers better durability and is less prone to wear and poor contact due to prolonged use, thus ensuring long-term stable operation of the volume control function.

[0024] Example 1: This embodiment provides a volume-adjustable ear cup assembly 1000, which combines structural stability, tactile comfort, and precise adjustment in terms of volume adjustment.

[0025] For details, please refer to Figures 1 to 5 The volume control ear cup assembly 1000 includes a first housing 100, on which a roller 200 is rotatably connected. A transmission gear 300 is meshed with the inner side of the roller 200. The transmission gear 300 has a protruding connecting part 310. A rotary encoder 400 is drivenly connected to the connecting part 310. The rotary encoder 400 has a rotating part 410 adapted to the connecting part 310. The outer side of the roller 200 is exposed on the outer side of the volume control ear cup assembly 1000. The rotation of the roller 200 drives the rotating part 410 to rotate through the transmission gear 300. The rotary encoder 400 is connected to a PCB board 500.

[0026] The inner side of the roller 200 is provided with several first protruding teeth 220, and the outer side of the transmission gear 300 is provided with several second protruding teeth 320. The first protruding teeth 220 and the second protruding teeth 320 mesh with each other to achieve meshing transmission connection.

[0027] In use, touching the outer side of the scroll wheel 200 causes it to rotate, which in turn drives the transmission gear 300 to rotate. The transmission gear 300, through the connecting part 310, drives the rotating component 410 of the rotary encoder 400 to rotate. The rotary encoder 400 generates an electrical signal based on the rotation of the rotating component 410, which is then transmitted to the PCB board 500 to precisely adjust the volume. Because the scroll wheel 200 and the transmission gear 300 are meshed, the tooth profile design between them provides a precise transmission ratio, ensuring that each rotation of the volume scroll wheel 200 is accurately transmitted to the rotary encoder 400, thus achieving precise volume adjustment.

[0028] In this embodiment, the rotating member 410 has a mating channel in its middle, which penetrates the middle of the rotary encoder 400. The connecting part 310 of the transmission gear 300 is adapted to the mating channel. The interface of the connecting part 310 is hexagonal, and the inner diameter of the rotating member 410, i.e., the cross-section of the mating channel, is also hexagonal. When the connecting part 310 rotates with the transmission gear 300, it can transmit power to the rotating member 410, causing the rotating member 410 to rotate.

[0029] Preferably, the scroll wheel 200 is an annular structure located above the first housing 100 and along the outer periphery of the first housing 100. The outer side of the scroll wheel 200 is fully exposed outside the first housing 100, which increases the control area for volume adjustment and helps to optimize the user experience.

[0030] It should be noted that the first housing 100 is provided with a first rotating groove 110, and the roller 200 is provided with a protrusion 210 below it. The protrusion 210 is confined within the first rotating groove 110, and the roller 200 rotates along the first rotating groove 110 via the protrusion 210. Specifically, the upper part of the first housing 100 is provided with an annular first protruding edge 101 and a second protruding edge 102. The first protruding edge 101 is located opposite to the inner side of the second protruding edge 102, and the first protruding edge 101 is higher than the second protruding edge 102. The first rotating groove 110 is formed between the first protruding edge 101 and the second protruding edge 102, forming an annular structure. A plurality of protruding protrusions 210 are provided at intervals below the roller 200. The roller 200 rotates along the first rotating groove 110 via the protruding edges, which is beneficial for the user to rotate the roller 200.

[0031] Furthermore, the volume control ear 1000 also includes a second housing 600, which is located above the scroll wheel 200, with the upper limit of the scroll wheel 200 in the vertical direction located between the first housing 100 and the second housing 600.

[0032] Specifically, the first housing 100 includes a first outer ring 130 and a first base 120 located inside the first outer ring 130, with a transmission gear 300 connected to the first base 120. A first protrusion 101 and a second protrusion 102 are both disposed on the first outer ring 130, and a roller 200 is rotatably connected to the first outer ring 130. The first base 120 has a second rotating groove 140, with the transmission gear 300 rotatably connected to the second rotating groove 140. The second rotating groove 140 is a circular structure adapted to the transmission gear 300, with the transmission gear 300 confined within and rotating within the second rotating groove 140. A connecting portion 310 protrudes upward from the middle of the transmission gear 300, and a rotary encoder 400 is located above the transmission gear 300. Simultaneously, the transmission gear 300 and the rotary encoder 400 are confined between the first housing 100 and the second housing 600.

[0033] Specifically, to further enhance the user experience, the outer side of the scroll wheel 200 is provided with several spaced-apart levers 240, each lever 240 having an "L"-shaped cross-section. In this embodiment, the levers 240 also protrude beyond the outer side of the second convex edge 102, allowing the user to better identify the location of the scroll wheel 200. Furthermore, the spaced-apart levers 240 provide the user with a point of leverage, making volume adjustment easier and more convenient, and facilitating blind operation.

[0034] Example 2: This embodiment further optimizes the structure based on Embodiment 1. Please refer to the reference. Figures 1 to 5 Key reference Figure 5 .

[0035] It should be noted that, similar to the first housing 100, the second housing 600 includes a second outer ring 620 and a second base 610. The second outer ring 620 has a stop 640 protruding in the direction of the roller 200, i.e., the stop 640 protrudes downwards from below the second outer ring 620. A third raised edge 230 is located above the roller 200, and the stop 640 abuts against the inner side of the third raised edge 230, providing inner support for the roller 200. When the user presses the roller 200 and pushes it to rotate, the roller 200 exhibits good stability, optimizing the user experience.

[0036] Furthermore, the PCB board 500 is connected above the second base 610 and to the rotary encoder 400. The second base 610 has a clearance hole 630, and the transmission gear 300 and the rotary encoder 400 are confined between the first housing 100 and the second housing 600, with the rotary encoder 400 exposed in the clearance hole 630 for connection to the PCB board 500. The first housing 100 and the second housing 600 are locked together. The first base 120 and the second base 610 have several through holes, through which fasteners pass to achieve a locked connection between the first housing 100 and the second housing 600. After the first housing 100 and the second housing 600 are locked together, the roller 200, the transmission gear 300, and the rotary encoder 400 are confined between the first housing 100 and the second housing 600.

[0037] Furthermore, the volume control earcup assembly 1000 also includes an intermediate component 700, a third housing 800, and a sound-generating module 900. The sound-generating module 900 and the transmission gear 300 are respectively located on both sides of the first base 120. The sound-generating module 900 is electrically connected to the PCB board 500. Ear pads can be connected to the side of the first housing 100 where the sound-generating module 900 is located.

[0038] On the side opposite to the sound-generating module 900, an intermediate component 700 and a third housing 800 are sequentially connected to the PCB board 500. The third housing 800 and the intermediate component 700 are connected to the second housing 600.

[0039] Example 3: This embodiment provides an earphone based on embodiment 2, such as... Figure 6 As shown, the headphones include a headband 2000 and the aforementioned volume-adjusting earcup assembly 1000, with the volume-adjusting earcup assembly 1000 connected to both sides of the headband 2000.

[0040] The volume control earcup assembly 1000 includes a first housing 100, on which a roller 200 is rotatably connected. A transmission gear 300 is meshed with the inner side of the roller 200. The transmission gear 300 has a protruding connecting part 310. A rotary encoder 400 is drivenly connected to the connecting part 310. The rotary encoder 400 has a rotating component 410 adapted to the connecting part 310. The outer side of the roller 200 is exposed on the outer side of the volume control earcup assembly 1000. The rotation of the roller 200 drives the rotating component 410 to rotate through the transmission gear 300. The rotary encoder 400 is connected to a PCB board 500.

[0041] The volume-adjustable earcup assembly 1000 adjusts the volume by rotating the roller 200 and driving the encoder 400 through the transmission gear 300.

[0042] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
