Description

Technical Field

[0001] This application relates to the field of loudspeaker technology, and more particularly to a bone conduction headphone. Background Technology

[0002] Bone conduction headphones are a type of headphone that uses bone conduction to transmit sound. They include a bone conduction sound-generating device for producing sound. Compared to the traditional method of transmitting sound through sound waves, bone conduction transmits vibrations directly to the auditory nerve through the bone, eliminating many steps in the sound wave transmission process. Therefore, it allows both ears to be open without damaging the eardrum, and it can achieve clear sound reproduction in noisy environments. Moreover, the sound waves will not affect others due to diffusion in the air, which is why it is loved by many consumers.

[0003] However, existing bone conduction headphones can cause pain due to prolonged pressure on the user's skin after wearing them for extended periods, making them unsuitable for long-term use. Utility Model Content

[0004] This application provides a bone conduction headphone, which aims to improve the wearing comfort of bone conduction headphones.

[0005] To address the aforementioned technical problems, this application provides a bone conduction headphone, comprising:

[0006] Two movement modules; and

[0007] Two ear hook assemblies include a housing, a bending transition portion, an earphone fixing portion, and a flexible layer. The earphone fixing portion is connected to the core module. The bending transition portion connects the housing and the earphone fixing portion. The bending transition portion is arc-shaped and is used to hang between the user's auricle and scalp. The flexible layer covers part of the outer surface of the housing. The flexible layer includes a first wrapping portion, which wraps around one end of the housing that abuts against the auricle when worn.

[0008] In some embodiments, the flexible layer further includes a second wrapping portion connected to the first wrapping portion and extending from the first wrapping portion in a direction away from the bending transition portion, the second wrapping portion wrapping around the accommodating compartment and abutting against the upper edge of the user's scalp when worn.

[0009] In some embodiments, the outer surface of the accommodating compartment is provided with a receiving groove, the first wrapping part and the second wrapping part are embedded in the receiving groove, and the outer surfaces of the first wrapping part and the second wrapping part are both coplanar with the exposed surface of the accommodating compartment.

[0010] In some embodiments, the flexible layer further includes a third wrapping portion connected to the first wrapping portion and wrapped around the outside of the bending transition portion.

[0011] In some embodiments, the first wrapping part, the second wrapping part, and the third wrapping part are an integral structure.

[0012] In some embodiments, the first wrapping portion, the second wrapping portion, and the third wrapping portion are all made of silicone.

[0013] In some embodiments, the outer surface of the accommodating compartment is provided with a connecting groove, and the inner wall surface of the flexible layer is provided with a connecting protrusion, which is engaged in the connecting groove.

[0014] In some embodiments, the accommodating compartment includes a first housing and a second housing that are interlocked together, and the bent transition is connected to one of the first housing and the second housing;

[0015] A wrapping cavity is formed within the first wrapping portion, and both the first shell and the second shell are housed within the wrapping cavity at the end that abuts against the auricle when worn.

[0016] In some embodiments, the headphone unit is provided in two parts, and the bone conduction headphones further include:

[0017] The neckband assembly is connected at both ends to the housings of the two headphone units, respectively.

[0018] In some embodiments, a battery is disposed in the housing of one of the earphone units, and a control board is disposed in the housing of the other earphone unit.

[0019] The bone conduction headphones in this embodiment utilize a flexible layer to enclose the ear canal. This allows the flexible layer to abut against the auricle when the headphones are worn, thereby reducing pressure on the auricle and improving wearing comfort. Furthermore, the flexible layer only encloses a portion of the ear canal. Specifically, the first part of the flexible layer encloses the end of the ear canal that abuts against the auricle during wear, eliminating the need to enclose the entire ear canal and thus reducing the cost of the bone conduction headphones.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] Bone conduction headphones are a type of headphone that uses bone conduction to transmit sound. They include a bone conduction sound-generating device for producing sound. Compared to the traditional method of transmitting sound through sound waves, bone conduction transmits vibrations directly to the auditory nerve through the bone, eliminating many steps in the sound wave transmission process. Therefore, it allows both ears to be open without damaging the eardrum, and it can achieve clear sound reproduction in noisy environments. Moreover, the sound waves will not affect others due to diffusion in the air, which is why it is loved by many consumers.

[0029] However, existing bone conduction headphones can cause pain due to prolonged pressure on the user's skin after wearing them for extended periods, making them unsuitable for long-term use.

[0030] Please see Figure 1 as well as Figure 2To address the aforementioned issues, this application provides a bone conduction headphone 1. The bone conduction headphone 1 includes a headphone unit 10, which includes a mechanism module 11 and an ear hook assembly 12. The ear hook assembly 12 is worn on the user's ear. The mechanism module 11 conforms to the user's head and contacts the user's skin. During operation, the mechanism module 11 generates mechanical vibrations carrying sound signals. These mechanical vibrations transmit the sound signals to the user through the skin, skull / jawbone, auditory hair cells in the cochlea, and auditory nerve.

[0031] In one embodiment, the movement module 11 has a vibration unit that generates mechanical vibration. This vibration unit can be a moving coil vibration unit, a moving iron vibration unit, a piezoelectric vibration unit, a magnetostrictive vibration unit, etc. Furthermore, a movement module 11 can contain one vibration unit, have two vibration units, or even be arranged in an array with multiple vibration units; this application does not impose any limitations on this. For example, when using two vibration units, they can each be responsible for different frequency bands, such as independent crossover of high and low frequencies. This allows the high-frequency unit (e.g., a moving iron) to resolve details, while the low-frequency unit (e.g., a moving coil or magnetostrictive) enhances bass extension.

[0032] In one embodiment, the bone conduction headphones 1 can be a single headphone unit 10, which can be applied to scenarios such as hearing aids for hearing-impaired patients and prompting for live broadcasts. In other embodiments, the bone conduction headphones 1 can also be provided with two headphone units 10, so that when the user wears the bone conduction headphones 1, the core modules 11 of the two headphone units 10 are located on the left and right sides of the user's head, respectively. During use, both core modules 11 emit sound, thus enabling the bone conduction headphones 1 to achieve stereo sound effects.

[0033] Understandably, the bone conduction headphones 1 also include an electronic control module 13, which includes an electrically connected battery 131 and a control board 132. The battery 131 is used to provide power for the operation of the core module 11, and the control board 132 can be used to control the sound output of the core module 11 (mainly converting electrical signals into mechanical vibrations). The battery 131 can be a rechargeable lithium battery or a dry cell battery, and this application does not limit it.

[0034] In the case of two headphone units 10, in order to prevent the weight of a single headphone unit 10 from being too heavy, in one embodiment, one of the two headphone units 10 may be provided with a battery, and the other of the two headphone units 10 may be provided with a control board.

[0035] The following content will be further elaborated on the bone conduction headphones 1 having two headphone units 10.

[0036] Please see Figure 1 In one embodiment, in addition to having two headphone units 10, the bone conduction headphones 1 also include a neckband assembly 14, with its two ends connected to two core modules 11 respectively. This arrangement allows the neckband assembly 14 to wrap around the back of the user's head, facilitating the wearing of the bone conduction headphones 1. Simultaneously, when the user wears the bone conduction headphones 1, the two core modules 11, through the cooperation of the two ear hook assemblies 12 and the neckband assembly 14, can better hold the user's head and make contact with the user's skin, thereby improving the sound reception of the core modules 11. Furthermore, when one headphone unit 10 has a battery and the other headphone unit 10 has a control board, the control board 132 and the battery 131 can be connected via wires embedded in the neckband assembly 14.

[0037] Specifically, the neckband assembly 14 may include an elastic metal wire, a conductive wire, and an elastic covering that encapsulates the elastic metal wire and the conductive wire. The elastic covering and the conductive wire are an integrally formed extruded structure; the covering further has a threading channel within which the elastic metal wire passes. Preferably, the threading channel is formed during the extrusion molding process. Furthermore, the elastic metal wire may be made of, but is not limited to, spring steel, titanium alloy, titanium-nickel alloy, chromium-molybdenum steel, etc., and the elastic covering may be made of, but is not limited to, polycarbonate, polyamide, silicone, rubber, etc., so that the neckband assembly 14 can balance wearing comfort and structural rigidity.

[0038] Please see Figure 3 In one embodiment, the ear hook assembly 12 includes a receiving compartment 121, a bending transition portion 122, an earphone fixing portion 123, and a flexible layer 124. The earphone fixing portion 123 is connected to the core module 11. The bending transition portion 122 connects the receiving compartment 121 and the earphone fixing portion 123. The bending transition portion 122 is arc-shaped and is used to hang between the user's auricle and scalp. The earphone fixing portion 123 can be connected by a snap-fit, adhesive, or plug-in method, without specific limitations. Since the bending transition portion 122 needs to hang between the user's auricle and scalp, and different users have different auricle shapes, the bending transition portion 122 is provided with an elastic metal wire to allow the user to adjust the shape of the bending transition portion 122 according to their needs, and to enhance the strength of the bending transition portion 122, thereby increasing the reliability of the ear hook assembly 12.

[0039] In one embodiment, when a user wears the bone conduction headphones 1, the housing 121 is located behind the user's auricle and abuts against the user's auricle. The housing 121 abuts against the auricle to further support the headphone unit 10, so that the headphone unit 10 can be hung more stably on the user's auricle. However, the outer shell of the housing 121 is relatively hard. After the user wears the bone conduction headphones 1 for a long time, the user's auricle will feel pain due to prolonged pressure.

[0040] Therefore, the flexible layer 124 covers part of the outer surface of the housing 121. The flexible layer 124 includes a first covering portion 1241, which covers the end of the housing 121 that abuts against the auricle during wear. This arrangement, with the housing 121 abutting against the user's auricle via the first covering portion 1241, not only improves the wearing stability of the bone conduction headphones 1 but also alleviates pain caused by pressure from the housing 121, thereby improving the wearing comfort of the bone conduction headphones 1.

[0041] Please see Figure 2 A flexible layer 124 covers a portion of the outer surface of the receiving chamber 121. The flexible layer 124 includes a first covering portion 1241, which covers the receiving chamber 121 and abuts against one end of the auricle during wear. The flexible layer 124 can be made of, but is not limited to, polycarbonate, polyamide, acrylonitrile-butadiene-styrene copolymer, polystyrene (PS), high-impact polystyrene, polypropylene, polyethylene terephthalate, polyvinyl chloride, polyurethane, polyethylene, phenolic resin, urea-formaldehyde resin, melamine-formaldehyde resin, silicone, etc., to improve the wearing comfort of the bone conduction headphones 1. The flexible layer 124 can be installed in the receiving chamber 121 by snap-fitting or adhesive bonding; no specific limitation is made here.

[0042] In this embodiment of the bone conduction headphones 1, a flexible layer 124 is provided to wrap the housing 121, so that when the bone conduction headphones 1 are worn, the flexible layer 124 abuts against the auricle, thereby relieving the pressure of the bone conduction headphones 1 on the auricle and improving the wearing comfort of the bone conduction headphones 1. At the same time, the flexible layer 124 of this application only wraps a portion of the housing 121. In particular, the first wrapping part 1241 of the flexible layer 124 wraps the end of the housing 121 that abuts against the auricle when worn, without having to wrap the entire housing 121, thereby reducing the cost of the bone conduction headphones 1.

[0043] Please see Figure 2In one embodiment, the flexible layer 124 further includes a second wrapping portion 1242, which is connected to the first wrapping portion 1241 and extends from the first wrapping portion 1241 in a direction away from the bending transition portion 122. The second wrapping portion 1242 wraps around the receiving chamber 121 and abuts against the upper edge of the user's scalp when worn. This configuration, where the upper edge of the receiving chamber 121 contacts the user's scalp through the second wrapping portion 1242, increases the contact area between the bone conduction headphones 1 and the user's head, thereby improving the wearing stability of the bone conduction headphones 1 and enhancing the wearing comfort of the bone conduction headphones 1.

[0044] Further, please refer to Figure 3 The outer surface of the accommodating chamber 121 is provided with a receiving groove 1211. The first wrapping part 1241 and the second wrapping part 1242 are embedded in the receiving groove 1211, and the outer surfaces of the first wrapping part 1241 and the second wrapping part 1242 are both coplanar with the exposed surface of the accommodating chamber 121. This arrangement reduces the impact of the flexible layer 124 on the thickness of the ear hook assembly 12, thereby making it easier for the user to wear the bone conduction headphones 1. Preferably, the outer peripheral surface of the flexible layer 124 is coplanar with the outer surface of the accommodating chamber 121 that is not covered by the flexible layer 124.

[0045] Please see Figure 4 In one embodiment, the flexible layer 124 further includes a third wrapping portion 1243, which is connected to the first wrapping portion 1241 and wraps around the outside of the bending transition portion 122. This arrangement allows the bending transition portion 122 to contact the user's auricle and scalp through the second wrapping portion 1242, thereby improving the wearing comfort of the bone conduction headphones 1.

[0046] Specifically, the bone conduction headphones 1 also includes a wire connecting the core module 11 and the electronic control module 13. The third wrapping part 1243 is provided with two wire passages. The bending transition part 122 is provided in one wire passage, and the wire is provided in the other wire passage. With this arrangement, the wire can be stored and protected by the third wrapping part 1243, thereby simplifying the structure of the bone conduction headphones 1.

[0047] Please see Figure 4 The first wrapping part 1241, the second wrapping part 1242, and the third wrapping part 1243 can be set separately, or they can be an integral structure. Preferably, the first wrapping part 1241, the second wrapping part 1242, and the third wrapping part 1243 are an integral structure. This simplifies the installation steps of the bone conduction headphones 1 and reduces the cost of the flexible layer 124, thereby reducing the cost of the bone conduction headphones 1.

[0048] Please see Figure 4In one embodiment, the first wrapping portion 1241, the second wrapping portion 1242, and the third wrapping portion 1243 are all made of silicone. Silicone has a low elastic modulus and a high elongation (up to 500%-1000%), and can still return to its original shape after repeated stretching or compression, exhibiting strong fatigue resistance. Silicone has strong resistance to water, oxygen, ozone, ultraviolet rays, etc., and is not easily corroded by chemicals such as acids, alkalis, and salts. The surface friction of silicone is high, providing good anti-slip properties, making it convenient for users to wear bone conduction headphones 1 during outdoor sports. The elasticity and density of silicone give it good sound insulation and cushioning properties, resulting in good wearing comfort.

[0049] Please see Figure 3 as well as Figure 4 In one embodiment, the outer surface of the accommodating compartment 121 is provided with a connecting groove 1212, and the inner wall surface of the flexible layer 124 is provided with a connecting protrusion 1244, which engages with the connecting groove 1212. This arrangement, through the cooperation of the connecting protrusion 1244 and the connecting groove 1212, avoids misalignment caused by friction between the flexible layer 124 and the user's skin, thus improving the wearing stability of the flexible layer 124.

[0050] Please see Figure 2 as well as Figure 3 In one embodiment, the accommodating compartment 121 includes a first housing 1213 and a second housing 1214 that are interlocked together, and a bent transition portion 122 is connected to one of the first housing 1213 and the second housing 1214; a wrapping cavity 124a is formed within the first wrapping portion 1241, and the ends of the first housing 1213 and the second housing 1214 that abut against the auricle when worn are both accommodated within the wrapping cavity 124a. This arrangement allows the first housing 1213 and the second housing 1214 to be wrapped and fixed within the wrapping cavity 124a, thereby improving the connection stability of the first housing 1213 and the second housing 1214.

[0051] Further, please refer to Figure 2 The connecting groove 1212 can be formed by the gap between the first housing 1213 and the second housing 1214. At the same time, the connecting protrusion 1244 extends into the gap between the first housing 1213 and the second housing 1214, which can effectively prevent the outer surface of the flexible layer 124 from being recessed, thus making the bone conduction headphones 1 more aesthetically pleasing.

[0052] When the storage compartment 121 is mainly used to accommodate the main control circuit board, such as Figure 3As shown, the ear hook assembly 12 may also include a control button 125. The control button is located on the receiving compartment 121 to facilitate connection between the control button 125 and the control board 132, thereby shortening the wiring distance. In this case, the control button 125 can be partially exposed on the outer surface of the ear hook assembly 12 for user operation. With this configuration, the control button 125 can be used to turn the bone conduction headphones 1 on and off, adjust the volume, and perform other functions. Figure 3 As shown, the ear hook assembly 12 may also include an indicator light 126. The indicator light 126 can be mounted on the receiving compartment 121 to facilitate connection with the control board 132, thereby shortening the wiring distance. In this case, the indicator light 126 may be partially exposed on the outer surface of the ear hook assembly 12, or it may specifically include an LED light source concealed within the ear hook assembly 12 and a light guide partially exposed on the outer surface of the ear hook assembly 12. With this configuration, the indicator light 126 can provide alerts when the bone conduction headphones 1 are charging or low on battery, and can also serve as a warning to pedestrians when the user is walking at night.
