Description

Technical Field

[0001] This invention relates to an earphone device, and more particularly to an over-ear headphone. Background Technology

[0002] With the rapid development of technology, various electronic products are evolving even faster. Among them, headphones can serve as a medium for sound transmission between electronic devices and the human ear, transmitting sound information to the human ear.

[0003] For headphones, since everyone's head shape is different, some users may feel uncomfortable when wearing headphones because the earcups do not fit the contours of their heads. Therefore, further design is needed to improve the adjustability of the earcups. Summary of the Invention

[0004] This invention provides a headset that improves the flexibility of earcups adjustment and significantly reduces manufacturing costs.

[0005] The present invention relates to a headset comprising a headband and two earcups connected to opposite ends of the headband, each earcup including an adjustment assembly. The adjustment assembly includes a base, two elastic elements, two protrusions, and two sliders. The base has two opposing receiving portions and two guide grooves. The elastic elements are respectively disposed within these receiving portions and extend along a first axial direction. The protrusions are respectively slidably engaged with these guide grooves and protrude into these receiving portions. The sliders are respectively disposed within these receiving portions and each slider is respectively connected between a corresponding protrusion and a corresponding elastic element. When an external force is applied to each earcup and causes each earcup to expand outward by an angle along a second axial direction of the first axial direction, each earcup drives its corresponding base, causing each protrusion to move within its respective guide groove and pushing each slider to move along the first axial direction to compress each elastic element. When the external force is removed, each earcup returns to its original position due to the elastic force of its elastic elements.

[0006] In one embodiment of the invention, each of the earmuffs further includes a housing and a front cover. The housing has an open end and a bottom wall. The front cover covers the open end of the housing, wherein each adjustment component is respectively connected between the headband and the corresponding bottom wall.

[0007] In one embodiment of the present invention, each of the earcups further includes a speaker. The speaker is disposed within an accommodating space formed by the housing and the front cover, and the speaker has a sound-emitting surface facing an inner surface of the front cover, the inner surface of which faces the bottom wall.

[0008] In one embodiment of the present invention, each of the above-mentioned guide grooves has a first section and a second section connected to the first section, the first section being parallel to a first axial direction, and the second section extending from the end of the first section in a direction inclined to the first axial direction.

[0009] In one embodiment of the present invention, each of the above-mentioned sliders has an inclined surface and a bottom surface, each bottom surface is connected to one end of each elastic element, and each inclined surface is inclined to the first axial direction.

[0010] In one embodiment of the present invention, each of the aforementioned inclined surfaces abuts against each of the protruding posts. When an external force is applied to each earmuff, each protruding post moves from the first segment to the second segment and from a first abutting position on the inclined surface to a second abutting position, thereby pushing each slider. A first distance between the first abutting position and the bottom surface is less than a second distance between the second abutting position and the bottom surface.

[0011] In one embodiment of the present invention, the base further includes two first sidewalls and two second sidewalls connected to the first sidewalls, each guide groove is formed on each first sidewall, each second sidewall corresponds to each bottom surface, and each second sidewall is connected to the other end of each elastic member.

[0012] In one embodiment of the present invention, the extension direction of the aforementioned second sidewalls is parallel to the second axial direction, and the extension direction of the aforementioned first sidewalls is parallel to the first axial direction.

[0013] In one embodiment of the invention, each of the above-described adjustment components further includes a rod and a sleeve. The rod has a first end and a second end opposite to each other, the first end being connected to the headband, and the second end extending in a direction having a rotational axis. The sleeve is disposed between the receiving portions of the base, the sleeve including two pivot portions and having a hollow portion, the second end being connected to the hollow portion, and the pivot portions being pivotally connected to the first sidewalls.

[0014] In one embodiment of the present invention, each of the above-described adjustment components further includes a positioning member. The positioning member is sleeved on the portion of the second end that passes through the hollow portion, and the positioning member includes a baffle to limit the rotation angle of each earcup in the rotational axis of the second end.

[0015] Based on the above, in the headphones of the present invention, the earcups can be adjusted by adjusting the components to fit the user's head shape. When the user removes the headphones, the earcups can automatically return to their original position by adjusting the elastic force of the elastic element in the components. Therefore, the headphones of the present invention improve the freedom of adjustment of the earcups and significantly reduce manufacturing costs.

[0016] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings. Attached Figure Description

[0065] Figure 1 This is a front view of a headset according to an embodiment of the present invention. Please refer to... Figure 1 The headset 1 includes a headband 20 and two earcups 10 connected to opposite ends of the headband 20. The two earcups 10 correspond to the user's left and right ears, respectively. The headband 20 can be extended or shortened by an adjustment mechanism (not shown), and the method of adjusting the length of the headband 20 is not limited here. In this embodiment, the headset 1 is, for example, a wireless headphone device, but the invention is not limited thereto. It should be noted that since the earcup components for the left and right ears are essentially identical, the following description will use one of the two earcups as an example.

[0066] Figure 2A and Figure 2B yes Figure 1Disassembly diagram of the headphones. Figure 3 and Figure 4 yes Figure 1 The diagram shows some components of a headset from different viewing angles. Please refer to [the diagram first]. Figure 2A In this embodiment, the earcup 10 includes a housing 101, a front cover 102, and an ear pad 11. The housing 101 has an open end P1. The front cover 102 covers the open end P1 of the housing 101. The ear pad 11 is made of foam, which may be covered with a leather outer layer or a fabric outer layer, or may be made of flocked foam; this invention is not limited thereto.

[0067] In this embodiment, the earcup 10 also includes a speaker 103. The speaker 103 is disposed in an accommodating space C1 formed by the housing 101 and the front cover 102. The speaker 103 has a sound-emitting surface S1, which faces an inner surface S2 of the front cover 102, so that the sound generated by the speaker 103 can be transmitted more smoothly to the user's ear canal.

[0068] For details, please refer to Figure 2A and Figure 3 The housing 101 has a bottom wall BW. The earcups 10 of this embodiment include an adjustment assembly 100, which is connected between the headband 20 and the bottom wall BW. In this embodiment, the inner surface S2 of the front cover 102 and the bottom wall BW of the housing 101 face each other, but this is not a limitation of the invention.

[0069] Please refer to Figure 2B and Figure 3 In this embodiment, the adjustment assembly 100 includes a base 110, two elastic elements 120, two protrusions 130, and two sliders 140. The base 110 has two opposing receiving portions 111 and two guide grooves 112. The protrusions 130 are slidably engaged with the guide grooves 112. The elastic elements 120 extend along a first axial direction A1 and are disposed within the receiving portions 111. In this embodiment, the protrusions 130 are cylindrical, but the invention is not limited thereto.

[0070] Please refer to Figure 4 In this embodiment, sliders 140 are respectively disposed within these receiving portions 111, and protrusions 130 protrude into these receiving portions 111. Each slider 140 is respectively connected between the corresponding protrusion 130 and the corresponding elastic member 120.

[0071] Figure 5A and Figure 5B yes Figure 1A schematic diagram of the operation of the headphones. In this embodiment, when an external force is applied to the earcups 10 and the earcups 10 expand outward by an angle α along a second axis A2, the earcups 10 drive the base 110, causing the protrusions 130 to move within the guide grooves 112, and pushing the slider 140 to move along the first axis A1, thereby compressing the elastic element 120 as... Figure 5B As shown. When the external force is removed, the earcups 10 are freed from their original position by the elastic force of the elastic element 120. Figure 5B The state shown is reset to Figure 5A The initial state. In this embodiment, the angle α is, for example, about 15 degrees, but the invention is not limited thereto.

[0072] With the above configuration, the headphones 1 can improve the adjustment freedom of the earcups 10 and significantly reduce manufacturing costs.

[0073] For more details, please refer to Figure 5A and Figure 5B In this embodiment, the guide groove 112 has a first segment 1121 and a second segment 1122 connected to the first segment 1121. The first segment 1121 is parallel to the first axial direction A1, and the second segment 1122 extends from the end of the first segment 1121 in a direction inclined to the first axial direction A1.

[0074] In this embodiment, the slider 140 has an inclined surface F1 and a bottom surface F2. The bottom surface F2 is connected to one end E2 of the elastic element 120, and the inclined surface F1 is inclined to the first axial direction A1. The displacement distance of the slider 140 can be adjusted by adjusting the length of the inclined surface F1, thereby changing the compression amount of the elastic element 120.

[0075] In this embodiment, the inclined surface F1 abuts against the protrusion 130. When an external force is applied to the earmuff 10, the protrusion 130 moves from the first segment 1121 to the second segment 1122, and from... Figure 5A The first contact position F11 shown is moved to Figure 5B The second abutment position F12 is shown to push the slider 140 toward the elastic member 120. In this embodiment, a first distance D1 between the first abutment position F11 and the bottom surface F2 of the slider 140 is smaller than a second distance D2 between the second abutment position F12 and the bottom surface F2 of the slider 140.

[0076] Furthermore, please refer to Figure 2B and Figure 3 In this embodiment, the base 110 further includes two first sidewalls W1 and two second sidewalls W2 connected to the two first sidewalls W1. A guide groove 112 is formed on the first sidewalls W1, and the second sidewalls W2 correspond to the bottom surface F2 of the slider 140. The second sidewalls W2 are connected to one end E1 of the elastic member 120. In this embodiment, both the first sidewalls W1 and the second sidewalls W2 are perpendicular to the bottom wall BW.

[0077] In this embodiment, the extension direction of these second sidewalls W2 is parallel to the second axis A2, and the extension direction of these first sidewalls W1 is parallel to the first axis A1. Here, the first axis A1 is perpendicular to the second axis A2, but the present invention is not limited thereto.

[0078] Please refer to Figure 2A and Figure 2B In this embodiment, the adjustment assembly 100 further includes a rod 150. The rod 150 has a first end 151 and a second end 152 opposite to each other, and the first end 151 is connected to the headband 20. That is, in this embodiment, the opposite ends of the headband 20 are connected to the earmuffs 10 through the rod 150, but the present invention is not limited thereto.

[0079] In this embodiment, the adjusting assembly 100 further includes a sleeve 160. The sleeve 160 includes two pivot portions 161 and has a hollow portion 162. The second end 152 is connected to the hollow portion 162, and the pivot portions 161 are pivotally connected to the first sidewall W1 of the base 110 so that the rod 150 can rotate along the second axis A2 with the sleeve 160.

[0080] Please refer to Figure 3 In this embodiment, the extension direction of the second end 152 of the rod 150 has a rotational axis Z1.

[0081] Please refer to Figure 4 In this embodiment, the sleeve 160 is disposed between the receiving portions 111 of the base 110. Here, the sleeve 160 includes a pivot portion 161, a plate body V1, and a protrusion 130, and is integrally formed, but the present invention is not limited thereto. Specifically, the two protrusions 130 are respectively connected to the two pivot portions 161 through the two plates V1, and the two pivot portions 161, the two protrusions 130, and the two plates V1 are disposed on opposite sides of the hollow portion 162, but the present invention is not limited thereto.

[0082] In this embodiment, each adjustment component 100 further includes a positioning member 170. The positioning member 170 is sleeved on the portion of the second end 152 of the rod 150 that passes through the hollow portion 162. The positioning member 170 includes a baffle 171 to limit the rotation angle of each earcup 10 on the rotation axis Z1 of the second end 152 of the rod 150. Specifically, when the earcup 10 rotates on the rotation axis Z1, the positioning member 170 will rotate accordingly, and the rotation range can be limited by the interference between the baffle 171 and the sleeve 160. In this embodiment, the rotation range of the earcup 10 of the headset 1 on the rotation axis Z1 is, for example, 90 degrees inward and 15 degrees outward, but the present invention is not limited thereto.

[0083] In summary, in the headphones of this invention, when an external force is applied to the earcups and causes them to expand outwards along a second axis, the earcups drive the base, causing the protrusions to move within the guide grooves and pushing the slider to move along the first axis, thereby compressing the elastic element. When the external force is removed, the earcups return to their original position due to the elastic force of the elastic element. In this way, the headphones can improve the adjustment freedom of the earcups and significantly reduce manufacturing costs.

[0084] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and refinements without departing from the scope of the present invention.
