Earphone with high adaptability

Abstract

A highly adaptable clip-on earphone includes a driver unit, a control unit, a main shell, and an ear stem. The main shell has a sound-emitting chamber with a sound hole at its front end for mounting the driver unit, and its rear end extends away from the sound-emitting chamber. The control unit is installed inside the main shell and electrically connected to the driver unit. The ear stem is made of a flexible, soft material and includes a connecting arm and a pressure block. The front end of the connecting arm connects to the rear end of the main shell to form a bridge with an accommodating space, and the rear end of the connecting arm connects to the pressure block. When the sound-emitting chamber is inserted into the concha of the ear, the connecting arm adapts to the ear, allowing the accommodating space to surround the auricle. The pressure block abuts against the back of the ear and can adapt independently. Therefore, this design, through the cooperation of the connecting arm and the pressure block, allows the ear stem to deform and rebound in multiple places, adapting to ears of different shapes and sizes to maintain wearing stability, and reducing the pressure exerted on the ear by the sound-emitting chamber and pressure block to ensure wearing comfort, thus improving adaptability and user experience.

Description

Technical Field

[0001] This utility model belongs to the field of headphone technology, and in particular relates to a highly adaptable clip-on headphone. Background Technology

[0002] With the development of acoustic output technology, Bluetooth headphones have been widely used in people's daily lives. As a new type of Bluetooth headphone, clip-on headphones can be clipped near the wearer's earlobe and allow the sound-producing part to extend into the concha to play sound. Because they do not block the ear canal, they can ensure safety when used in outdoor scenarios, and they are more comfortable to wear than traditional in-ear headphones.

[0003] However, existing clip-on headphones are difficult to fit ears of different shapes and sizes. That is, the same clip-on headphones can be worn stably and comfortably for some users, but for others, they may be too loose and fall out easily, or too tight and affect comfort. Therefore, it is necessary to design a clip-on headphone with high adaptability to solve this problem. Utility Model Content

The ear stem is made of a flexible soft material and includes a connecting arm and a pressure block. The front end of the connecting arm connects to the rear end of the main shell to form a bridge with an accommodating space, and the rear end of the connecting arm connects to the pressure block. When the sound-emitting chamber extends into the concha of the ear, the connecting arm undergoes adaptive deformation so that the accommodating space of the bridge surrounds the auricle, and the pressure block abuts against the back of the ear and can undergo adaptive deformation independently.

[0020] See appendix Figure 1 - Appendix Figure 10A highly adaptable clip-on earphone includes a sound-emitting unit 1, a control unit 2, a main shell 3, and an ear stem 4. The main shell 3 has a sound-emitting chamber 31 with a sound hole 310 for mounting the sound-emitting unit 1 at its front end, and the rear end of the main shell 3 extends away from the sound-emitting chamber 31. The control unit 2 is installed inside the main shell 3 and electrically connected to the sound-emitting unit 1. The ear stem 4 is made of a flexible soft material and includes a connecting arm 41 and a pressing block 42. The front end of the connecting arm 41 is connected to the rear end of the main shell 3 to form a bow bridge 32 with an accommodating space 320, and the rear end of the connecting arm 41 is connected to the pressing block 42. When the sound-emitting chamber 31 is inserted into the concha 51 of the ear 5, the connecting arm 41 undergoes adaptive deformation so that the accommodating space 320 of the bow bridge 32 surrounds the auricle 52, while the pressing block 42 abuts against the back of the ear 53 and can undergo adaptive deformation independently.

[0021] Specifically, when using it, first hold the main shell 3 and pry open the ear stem 4 so that the connecting arm 41 deforms and expands the accommodating space 320 of the bow bridge 32. Then, insert the sound-generating chamber 31 into the concha cavity 51 and surround the auricle 52 through the accommodating space 320. Finally, release the ear stem 4 so that the energy-releasing and rebounding connecting arm 41 drives the pressure block 42 to abut against the back of the ear 53. Then, the sound-generating chamber 31 and the pressure block 42 hold the ear 5 to complete the wearing. After wearing, the control unit 2 receives the signal and transmits it to the sound-generating unit 1, so that the sound generated by the sound-generating unit 1 enters the inner ear canal through the sound hole 310.

[0022] During wear, if the user's ear 5 is thin or small, the pressure block 42 can remain in its original shape and maintain the clamping range unchanged. At this time, the pressure block 42 is driven to stably abut against the back of the ear 53 by the rebound of the connecting arm 41. If the user's ear 5 is thick or large, the pressure block 42 will be squeezed by the back of the ear 53 and undergo adaptive deformation to expand the clamping range. At this time, the pressure block 42 is driven to stably abut against the back of the ear 53 by the rebound of the connecting arm 41 and the rebound of the pressure block 42.

[0023] For ease of understanding, this embodiment will analyze the issue from the perspectives of angular deformation and stress: As attached Figure 7As shown, in terms of angular deformation, assuming that the pressure block 42 forms an angle α1 when it is in the unfolded state, and that there is a distance b1 between the pressure block 42 and the sound-emitting chamber 31; then, after the ear 5 squeezes and deforms the pressure block 42, it forms an angle α2, and that there is a distance b2 between the pressure block 42 and the sound-emitting chamber 31; therefore, the actual expansion angle of the ear stem 4 when worn is α = α1 + α2, and the actual distance between the pressure block 42 and the sound-emitting chamber 31 is b = b1 + b2; based on this, it can be seen that when facing objects with thicker shapes or larger sizes... When the ear 5 and the pressure block 42 deform, α2 and b2 can replace a1 and b1 respectively. That is, the deformation of the pressure block 42 can replace the deformation of the connecting arm 41, ensuring that the connecting arm 41 can maintain a large wearing range to fit the ear 5 even when the swing angle is small. Since the connecting arm 41 is made of elastic material, the pressure applied by the connecting arm 41 remains unchanged when α1 and b1 are unchanged, so as to avoid the sound chamber 31 and the pressure block 42 excessively clamping the ear 5 and causing discomfort.

[0024] As attached Figure 8 As shown, from a force perspective, assuming the pressure exerted by the sound-generating chamber 31 on the ear clip cavity is F1, and the pressure exerted by the pressure block 42 on the back of the ear 53 is F2, F1 is generated by the contact friction between the sound-generating chamber 31 and the concha cavity 51, while F2 is generated by the deformation and rebound of the connecting arm 41 and transmitted to the back of the ear 53 by the pressure block 42. When the pressure block 42 deforms independently, it will rebound and generate pressure F3. F3 can effectively offset part of F2, making F2 smaller. This means that the connecting arm 41 can withstand deformation or only undergo small deformation. In this way, the ear clip-on headphones can be adapted to fit other sizes of ears 5. Since the pressure block 42 can perfectly fit the contour of the back of the ear 53 after deformation, F3 will be evenly distributed at each contact point between the pressure block 42 and the back of the ear 53, so that the pressure block 42 can stably contact the back of the ear 53 and ensure that the force at each contact point of the back of the ear 53 is smaller. Therefore, by reducing F2 and evenly distributing F3, the pressure exerted on the ear 5 by the sound chamber 31 and the pressure block 42 can be effectively reduced to ensure comfort, thereby achieving a seamless wearing effect.

[0025] In summary, this utility model, by installing a deformable connecting arm 41 and a pressure block 42 on the main shell 3 for use, allows the ear stem 4 to deform and rebound in multiple places. With this structural design, this ear clip-on earphone can not only adapt to ears 5 of different shapes and sizes to maintain wearing stability, but also reduce the pressure exerted on the ears 5 by the sound chamber 31 and the pressure block 42 to ensure wearing comfort, thus improving adaptability and user experience.

[0026] See appendix Figure 1 - Appendix Figure 9 The main shell 3 is made of a hard material, and the ear stem 4 is made of any one of silicone, TPE, or TPU.

[0027] Specifically, the main shell 3 is made of a hard material, which can better protect the control unit 2 and the sound unit 1, and prevent the main shell 3 from deforming and deviating from the concha cavity 51 during wearing, so as to ensure wearing stability; while the ear stem 4 is made of a soft material with elasticity, which can ensure that it has good deformation and recovery ability to provide sufficient rebound to achieve pre-tightening, and also make the contact between the pressure block 42 and the back of the ear 53 more gentle, so as to ensure wearing comfort.

[0028] Among them, hard materials can be hard metals, hard plastics, etc., while flexible soft materials can be silicone, TPE, TPU, etc. Since there are many types of hard materials and flexible soft materials, and they can all achieve the same or equivalent effects, this utility model does not impose any restrictions on them.

[0029] See appendix Figure 1 - Appendix Figure 9 The connecting arm 41 and the pressure block 42 are integrally formed.

[0030] Specifically, the integral molding of the connecting arm 41 and the pressure block 42 not only facilitates processing and production, reduces production difficulty and manufacturing costs, but also improves the overall structural stability and has a longer service life.

[0031] See appendix Figure 3 - Appendix Figure 5 The pressure block 42 has a columnar structure with a circular / elliptical cross-section.

[0032] Specifically, after wearing, the circumferential sidewall of the pressure block 42 contacts the back of the ear 53 to reduce friction. If the pressure block 42 deforms, the deformed pressure block 42 can still perfectly fit the contour of the back of the ear 53 to improve wearing stability and wearing comfort.

[0033] See appendix Figure 3 - Appendix Figure 9 A through hole 420 is provided in the middle of the pressure block 42 so that the cross-section of the pressure block 42 is annular.

[0034] Specifically, when the pressure block 42 is deformed by the ear back 53, it will deform inward towards the through hole 420, so that the side of the pressure block 42 that contacts the ear back 53 has a larger deformation range. Therefore, the design of the through hole 420 can provide the pressure block 42 with sufficient deformation space and also make the pressure block 42 have greater resilience. This increases the deformation and recovery ability of the pressure block 42 without increasing its volume, further improving wearing comfort and stability. On the other hand, users can also use the through hole 420 to hang personalized jewelry on the pressure block 42 to enrich the fun of use and increase aesthetics, further improving the user experience.

[0035] See appendix Figure 1 - Appendix Figure 9 The pressing block 42 has a contracted state within the accommodating space 320 and an unfolded state detached from the accommodating space 320.

[0036] Specifically, under normal circumstances, the pressure block 42 is in a retracted state to minimize the overall size of the product, making it convenient for users to place it in the corresponding charging case (not shown in the illustration) for charging; when wearing, the pressure block 42 is bent to the unfolded state so that the accommodating space 320 of the bow bridge 32 can expand to surround the auricle 52.

[0037] Therefore, the above structural design not only facilitates the overall storage and charging of the product, but also allows the connecting arm 41 to have a larger swing range while ensuring that the ear stem 4 has sufficient elasticity, further improving the user experience and wearing stability.

[0038] See appendix Figure 5 The vertical height from the tail end of the main shell 3 to the tail end of the connecting arm 41 is h, where 0.8cm≤h≤10cm.

[0039] Specifically, setting the length to 0.8cm≤h≤10cm ensures that the connecting arm 41 has sufficient deformation range and elasticity, while also ensuring ergonomic design and preventing the connecting arm 41 from being too long and causing the ear stem 4 to be mismatched with the shape of a regular ear 5. This allows the ear clip-on headphones to be worn stably while ensuring that the sound chamber 31 and the pressure block 42 can properly abut and hold the ear 5 and ensure wearing comfort.

[0040] See appendix Figure 7 The sound-generating chamber 31 has a concave design on the side wall near the pressure block 42 and is arc-shaped, with a concave distance of d, where 0cm < d ≤ 2cm.

[0041] Specifically, the concave and arc-shaped design of the side wall of the sound-generating chamber 31 near the pressure block 42 allows the curved surface formed by the side wall of the sound-generating chamber 31 to fit the shape and curvature of the ear clip cavity as much as possible, so as to effectively reduce local compression and reduce pain. Setting 0cm<d≤2cm allows the side wall of the sound-generating chamber 31 to slightly hook into the inner side of the concha cavity 51, ensuring that the sound-generating chamber 31 is not easy to fall out of the concha cavity 51.

[0042] See appendix Figure 1 - Appendix Figure 3 The main shell 3 has a bayonet 33 at its tail end, and the connecting arm 41 has a buckle 43 at its head end that engages with the bayonet 33. This design allows the main shell 3 and the ear stem 4 to be disassembled from each other, which is convenient for both initial assembly and subsequent disassembly and maintenance. Furthermore, with this design, the manufacturer can further set various length specifications of ear stem 4. By installing ear stems 4 of different specifications onto the main shell 3, the resulting headphones can be worn on more types of ears 5, further improving compatibility and ease of use.

[0043] See appendix Figure 1 - Appendix Figure 5 The sound unit 1 includes a speaker 11, and the control unit 2 includes a circuit board 21, a battery 22, and a charging pin 23. The speaker 11 is installed in the sound chamber 31 and is designed to correspond to the sound hole 310. The circuit board 21, the battery 22, and the charging pin 23 are all installed in the main shell 3, and the end of the charging pin 23 extends through the main shell 3 to the outside. The circuit board 21 is electrically connected to the speaker 11, the battery 22, and the charging pin 23.

[0044] Specifically, during use, the battery 22 supplies power to the circuit board 21 and the speaker 11. The circuit board 21 can receive audio signals from electronic devices such as mobile phones and tablets through signal modules such as Bluetooth and WiFi modules, decode them, and play them through the speaker 11. The sound played by the speaker 11 will overflow to the outside through the sound hole 310 and enter the inner ear canal. The charging pin 23 is used to contact the pin inside the charging box or directly contact the charging plug to facilitate charging of the battery 22.

[0045] It should be noted that the speaker 11, circuit board 21, battery 22 and charging pin 23 are all existing accessories and are widely used in this technical field. Therefore, their specific working principle and circuit structure will not be described in detail in this utility model. In addition, besides the above-mentioned accessories, the control unit 2 and the sound unit 1 can also use other accessories. Since there are many types of related accessories, this utility model does not limit them.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
