Description

Semi-open headphones Technical Field

[0001] The present invention relates to the field of electroacoustic conversion, and in particular to a semi-open earphone. Background Art

[0002] Smart wearable technology is changing our lifestyles, with headphones being the most prominent example. For young people in the AI ​​era, headphones are so commonplace that we barely even realize their increasing reliance on them. This isn't just because they convey sound; they empower the wearer with independence and the ability to create their own subjective reality. More importantly, as the boundaries between work and social life disappear, headphones have become a crucial modern mediator between public and private spaces.

[0003] As for headphones themselves, prolonged use can be harmful. Long-term use of headphones for phone calls or music can severely stimulate the auditory nerves of the eardrum due to the close proximity between the eardrum and the vibrating plate. This can cause dizziness, tinnitus, hearing loss, and hearing loss. Listening for several or even more than ten hours can also lead to sudden deafness. Chronic earplugs can cause irritation to the external auditory canal and lead to ear inflammation. Furthermore, prolonged use of headphones can lead to a constant state of mental tension, which is also detrimental to health.

[0004] Most traditional earphones are inserted into the ear and directly block the user's ear canal, making surface contact with the user's ear canal. During the wearing process, the ear canal and the external environment are completely blocked. On the one hand, this causes pain from wearing earphones for a long time, and it is also easy to cause the hygiene of the user's ear canal to deteriorate. On the other hand, it is easy for the user to have difficulty hearing external sounds while wearing them, which poses certain safety risks.

[0005] Traditional bone conduction headphones are widely known for their pain-free and protective properties. While they bypass the ear canal, preventing music from entering the ear and bypassing the eardrum, they also offer poor sound quality. Because sound is transmitted through the skin and bones to the ear ossicles, the separation and reproduction of music are poor, leading to issues such as sound leakage and a lack of immersion.

[0006] Traditional headphones typically use dynamic speakers, which typically produce better mid- and high-pitched sound but are unable to achieve excellent bass performance.

[0007] How to solve the problems of wireless Bluetooth headsets not getting tired when worn for a long time, being portable, preserving sound quality and ensuring sound fidelity is an urgent problem to be solved today. Summary of the Invention

[0013] Another advantage of the present invention is that it provides a semi-open earphone, which can be fixed by inserting one side into the ear and resting the other side against the back of the ear of the user, so that the earphone can be worn without falling off by only fixing the two sides.

[0014] Another advantage of the present invention is that it provides semi-open headphones, which can enhance the smart wearing and decorative features of the semi-open headphones by arranging decorative means such as diamonds on the outer surface.

[0015] Another advantage of the present invention is that it provides semi-open headphones, which can be worn in an adjustable clip-on manner to expand the audience group and adapt to customers of different age groups and ethnic groups.

[0016] Another advantage of the present invention is that it provides a semi-open earphone, the shape of which can be larger on the side away from the user's ear canal. On the one hand, it does not affect the user's wearing, and on the other hand, it can enhance the battery life performance of the semi-open earphone.

[0017] Another advantage of the present invention is that it provides a semi-open headphone that has a better sound output effect in the bass range than traditional headphones.

[0018] Another advantage of the present invention is that it provides semi-open headphones, the sound output of which has a certain heaviness and metallic texture, and the sound output effect is better, giving the user a mechanical experience.

[0019] Another advantage of the present invention is that it provides a semi-open earphone, which can achieve a stereo sound effect through the arrangement of the speaker holes when worn in the ear.

[0044] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0045] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0046] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0047] As shown in Figures 1 to 5, a semi-open earphone 1 according to a preferred embodiment of the present invention is illustrated. The semi-open earphone 1 is suitable for being worn on the ear of the user, with one end being suitable for extending and entering the ear canal 94 of the user, and the other end being against and located on the back of the auricle 93, so as to achieve long-term wearing without fatigue through the front-end wearing method of point contact, and ensure the output of sound effects through the shape of the front end. Furthermore, the semi-open earphone 1 spans across both sides of the user's auricle 93. In other words, the front end of the semi-open earphone 1 extends and is fixed in the concha 91 of the user, and the rear end extends to the back of the auricle 93 of the user.

[0048] For the sake of convenience, when the semi-open earphone 1 is placed on the ear of the user, the side to which the user's ear canal faces is defined as the front side, and the opposite side is defined as the back side.

[0049] The semi-open earphone 1 includes an in-ear speaker 10, an extended connection portion 20, and a behind-the-ear functional portion 30. The in-ear speaker 10, the extended connection portion 20, and the behind-the-ear functional portion 30 are interconnected. In other words, the semi-open earphone 1 is composed of three sections: the in-ear speaker 10, the extended connection portion 20, and the behind-the-ear functional portion 30.

[0050] The in-ear speaker 10 is adapted to provide a sound output function. The extended connection portion 20 is adapted to provide a connection, clamping, and fixing function. The behind-the-ear functional portion 30 is adapted to provide additional auxiliary functions. When the semi-open earphones 1 are worn, the in-ear speaker 10 is close to and extends deep into the user's ear canal 94, and the extended connection portion 20 spans the front and back sides of the user's auricle 93 and bypasses the helix 92. The behind-the-ear functional portion 30 is located on the back side of the user's auricle 93.

[0051] In particular, in this embodiment, the in-ear speaker 10 is implemented in a shuttle shape. Due to the characteristics of the shuttle shape being narrow at both ends and wide in the middle, when the in-ear speaker 10 of the semi-open earphone 1 extends into the user's ear canal 94, it does not completely close the ear canal 94, but leaves a gap in the ear canal 94 that is connected to the outside world, so as to avoid oppression to the user, achieve painless wearing for a long time, and avoid hearing damage due to the closure of the ear canal 94. The ear can still hear external sounds to avoid safety risks.

[0052] More specifically, as shown in Figures 3 to 5 , the in-ear speaker 10 includes an end face 101 and has a first side face 102 and a second side face 103. The end face 101 is smaller, while the first side face 102 and the second side face 103 are larger and face each other. When inserted into the user's ear canal 94, the in-ear speaker 10 faces the user's ear canal 94, while the first side face 102 and the second side face 103 face the outside of the ear and the auricle 93, respectively. The end face 101 tapers, decreasing in width toward the user's ear canal 94, thereby accommodating the end of the in-ear speaker 10 to be inserted into the user's ear canal 94.

[0053] The material of the extended connection part 20 is different from that of the in-ear speaker part 10 and the behind-the-ear functional part 30. Furthermore, the material of the extended connection part 20 is preferably a material with a certain degree of stretchability. By folding and bending the extended connection part 20, the semi-open earphone 1 is fixedly worn on the user's ear. In other words, the user bends the extended connection part 20 to bring the in-ear speaker part 10 close to the behind-the-ear functional part 30. The user adjusts the degree of bending of the extended connection part 20 to bring the semi-open earphone 1 close to and fit it to the user's ear to complete the wearing process. The adjustable wearing method can adapt to users of a wider age range and the size of the ears caused by different races. The wearing method is close to the user's ear, which avoids loss and reduces the cost of using the semi-open earphone 1.

[0054] The in-ear speaker 10 is in a spindle shape and extends into the user's ear canal 94, outputting sound effects to the user in an in-ear manner. However, compared to traditional in-ear headphones, the in-ear speaker 10 does not completely block the user's ear canal 94. On the one hand, it avoids the problem of wearing environment hygiene caused by the in-ear wearing method, and on the other hand, it reduces the discomfort caused by the increase in wearing time. The semi-open headphone 1 optimizes the original surface contact and turns it into a partial contact with the user's ear, further reducing the contact area with the user's ear surface, reducing the squeezing feeling caused by pressing the ear, and greatly reducing the pain caused by squeezing as the wearing time increases.

[0055] The in-ear speaker part 10 includes a speaker housing 11 and an ear-supporting connecting body 13 and a sound receiving cavity 14. The speaker housing 11 and the ear-supporting connecting body 13 are installed and connected to each other, and the sound receiving cavity 14 is formed between the speaker housing 11 and the ear-supporting connecting body 13. The ear-supporting connecting body 13 is integrally connected to the extended connecting part 20. When the semi-open earphone 1 is in the wearing state, the speaker housing 11 is located in the concha cavity 91 of the user and extends into the ear canal 94 of the user. The ear-supporting connecting body 13 is farther away from the ear canal of the user than the speaker housing 11.

[0056] The in-ear speaker part 10 includes a speaker component 12 and a plurality of speaker holes 15. The speaker component 12 is suitable for providing the function of sound output, and the speaker holes 15 are arranged on the speaker body 11. The speaker component 12 is located between the speaker body 11 and the ear-connecting body 13. In other words, the speaker component 12 is located in the sound receiving cavity 14. When the semi-open earphones 1 are worn, the speaker component 12 outputs sound from front to back to the user's ear canal. The speaker holes 15 are arranged on the side of the speaker body 11 rather than the end face, and are not facing the user's cavum concha 91.

[0057] That is, when conventional earphones are worn on the user's ears, their speakers are arranged and vibrate toward the user's ear canal 94 to produce sound. However, in the present invention, when the semi-open earphones are worn on the user's ears, the speaker member 12 and the speaker hole 15 are not in a vertical direction, nor are they facing the user's ear canal 94, but are facing the inner wall of the ear canal 94. The extended connection portion 20 includes an extended main body 21 and a clamping space 22. One end of the extended main body 21 is connected to the in-ear speaker portion 10, and the other end is connected to the behind-the-ear functional portion 30. In other words, the extended main body 21 is located between the in-ear speaker portion 10 and the behind-the-ear functional portion 30. The extended main body 21 is suitable for providing a connecting extension function. When the semi-open earphones 1 are in the wearing state, the extended main body 21 spans the front and back sides of the user's auricle 93. That is, the extended main body 21 bends and extends from the back side of the user's auricle 93 along the side of the auricle 93 to the front side. During the bending and stretching process, the extension body 21 approaches and fits the user's auricle 93 to adapt to the ear shapes of different people and facilitate wearing. The extension body 21 bends and surrounds to form the clamping space 22. The clamping space 22 is suitable for accommodating the user's auricle 93. The clamping space 22 is suitable for changing in real time according to the size of the user's ear to adjust the wearing comfort. When the in-ear speaker part 10 and the behind-the-ear functional part 30 move away from each other, the clamping space 22 becomes larger; when the in-ear speaker part 10 and the behind-the-ear functional part 30 move closer to each other, the clamping space 22 becomes smaller.

[0058] The clamping space 22 can be adjusted to change, so that the user has a certain degree of convenience in the process of wearing. For example, when the user is a deliveryman or a courier, usually, this user group has to drive a vehicle for a long time, while listening to the navigation, answering orders, customer messages, and always paying attention to the news of the external environment. By wearing the semi-open earphones 1. Due to the structural characteristics of the shuttle-shaped in-ear speaker 10, the semi-in-ear wearing method does not block the user's ear canal 94. At the same time, the auxiliary clamping and fixing of the extended connection part 20 avoids the loss of the earphones during driving. When arriving at the predetermined delivery address, the semi-open earphones 1 can also be easily removed by the bendability of the extended connection part 20. On the one hand, the wearing method will not cause long-term squeezing of the user's ear canal and thus avoid the pain caused by compression. On the other hand, it can be stably clamped and freely removed, ensuring the convenience of wearing and avoiding damage to the user's hearing caused by long-term wearing.

[0059] The back-ear functional portion 30 includes a functional connection body 31, a pair of functional covers 34, and a functional cavity 36. The functional connection body 31 is integrally connected to the extension body 21, and the functional covers 34 are adapted to be mounted on either side of the functional connection body 31. The functional cavity 36 is formed between the functional covers 34 and the functional connection body 31. The functional cavity 36 is adapted to store energy and information.

[0060] In this embodiment, the functional connection body 31, the ear-rest connection body 13, and the extension body 21 can be made of the same material, preferably a material with good ductility, so that when the semi-open earphones 1 are worn, the user can easily pinch the earphones and change the relative positional relationship between the functional connection body 31, the ear-rest connection body 13, and the extension body 21. By changing the relative positional relationship between the functional connection body 31, the ear-rest connection body 13, and the extension body 21, the size of the clamping space 22 can be changed to adapt to the shape of the user's ear, achieving a tight fit, and the adjustable clamping space 22 allows for easy removal.

[0061] The behind-the-ear functional portion 30 further includes a functional component 32 and a power supply component 33. The functional component 32 is adapted to provide information processing functions, and the power supply component 33 is adapted to provide energy replenishment functions. The functional component 32 and the power supply component 33 are installed in the functional cavity 36. The functional component 32 and the power supply component 33 are electrically connected to each other. Furthermore, the functional component 32 and the power supply component 33 are also electrically connected to the speaker component 12. In other words, the speaker component 12 is electrically connected to the power supply component 33 via the functional component 32. Furthermore, the information received and processed by the functional component 32 is transmitted to the speaker component 12, which converts the electrical signal into an acoustic signal and outputs the sound effect to the user's ear canal through the speaker hole 15.

[0062] The behind-the-ear functional portion 30 also includes at least one charging contact 35. In this embodiment, the number of the charging contacts 35 is actually two. The charging contact 35 is provided on the functional cover 34. The charging contact 35 is connected to the power supply component 33 at one end, and the other end extends and protrudes from the functional cover 34. The semi-open earphones 1 are externally energy-supplied through the charging contacts 35. In other words, the power supply component 33 is suitable for external energy supply through the charging contacts 35. In other words, when the semi-open earphones 1 are not in use, the user can charge and replenish them by contacting the charging contacts 35 with an external power source.

[0063] It is worth mentioning that when the semi-open earphones 1 are in the wearing state, the behind-the-ear functional part 30 is located on the back of the user's auricle 93, away from the user's cavum concha 91. In terms of manufacturing technology, the shape of the behind-the-ear functional part 30 can be made larger. In other words, the shape of the behind-the-ear functional part 30 is larger. Furthermore, the power supply component 33 located inside the functional cavity 36 can be larger. The larger capacity of the power supply component 33 can improve the battery life of the semi-open earphones 1. When the user works outdoors for a long time, they must always have navigation functions, etc., and there is no need to charge and recharge the semi-open earphones 1 frequently. The semi-open earphones 1 can be worn for long-term signal reception and positioning simulation, which is suitable for a wide audience.

[0064] Compared to dynamic speakers in traditional wireless Bluetooth headsets, which have better sound output in the mid- and high-pitched ranges but are unable to achieve good sound output in the bass range, the speaker component 12 of the semi-open headset 1 in this embodiment can achieve better sound output in the bass range, making the output sound heavier and providing a good sound quality experience based on the mechanical texture.

[0065] Specifically, the sound-speaker component 12 includes a mounting assembly 121, a magnetic return assembly 122, and a vibration assembly 123. The mounting assembly 121, the magnetic return assembly 122, and the vibration assembly 123 are mounted on each other. The mounting assembly 121 is suitable for providing rigid support and installation space, the magnetic return assembly 122 is suitable for providing electromagnetic conversion, and the vibration assembly 123 is suitable for providing sound output. The magnetic return assembly 122 is installed inside the mounting assembly 121, and the vibration assembly 123 is installed on the front end surface of the mounting assembly 121. The magnetic return assembly 122 and the vibration assembly 123 are combined to achieve electroacoustic conversion.

[0066] The mounting assembly 121 includes a housing 1211 and a cavity 1212 . The housing 1211 provides external rigidity support, and the cavity 1212 is adapted to provide an installation space. The housing 1211 surrounds and forms the cavity 1212 .

[0067] The magnetic return component 122 includes a magnet 1221, a core 1222 and a gasket 1223. The magnet 1221 is implemented as a permanent magnet in this embodiment, and the gasket 1223 is implemented as a washer in this embodiment. The magnet 1221, the core 1222 and the gasket 1223 are parallel to form a magnetic gap 1224. The magnetic gap 1224 provides a magnetic field to interact with the magnetic field of the vibration component 123 to drive the vibration component 123 to vibrate.

[0068] The vibration assembly 123 includes a diaphragm unit 1231, a weight layer 1232, a stacking layer 1233 and a voice coil unit 1234. The diaphragm unit 1231 is implemented as a planar diaphragm in this embodiment. The weight layer 1232 and the stacking layer 1233 are arranged on the diaphragm unit 1231. The voice coil unit 1234 is surrounded by the magnet 1221. One end of the voice coil unit 1234 is connected to the diaphragm unit 1231, and the other end extends into the magnetic return assembly 122 and the magnetic gap 1224. The voice coil unit 1234 is electrically connected to the functional component 32 to provide an input driving current to generate an electromagnetic field, and interacts with the magnetic field of the magnetic return assembly 122 to drive the voice coil unit 1234 to reciprocate. The voice coil unit 1234 drives the diaphragm unit 1231 to vibrate, thereby achieving sound output.

[0069] In this embodiment, the diaphragm unit 1231 may optionally be made of a plastic material, and the overlay layer 1233 may optionally be made of a metal material. The overlay layer 1233 is suitable for providing a metallic texture for sound effects, and the weight layer 1232 is suitable for providing a heavy texture for sound effects, thereby achieving low-frequency sound output. The overlay layer 1233 is attached to the diaphragm unit 1231. By providing the overlay layer 1233 on the flexible diaphragm unit 1231, the diaphragm unit 1231 is tightened and its rigidity is increased, reducing a certain degree of elasticity, thereby increasing the frequency of vibration, thereby improving the sound quality and sound effects, and reducing the distortion rate.

[0070] In this embodiment, the stacking layer 1233 is implemented as a mesh structure, distributed in a planar manner. Partial holes or grooves are implemented on the surface of the stacking layer 1233, so that the diaphragm unit 1231 is partially exposed at the location corresponding to the holes or grooves, thereby allowing the diaphragm unit 1231 to pump air. In this embodiment, the stacking layer 1233 further includes an annular layer 12331 and a sheet layer 12332. The annular layer 12331 is implemented as multiple concentric circles surrounding the inner side, and the sheet layer 12332 is located inside the annular layer 12331.

[0071] The weight layer 1232 is disposed in the center of the stacking layer 1233. In other words, the stacking layer 1233 surrounds the weight layer 1232. The weight layer 1232 is located at the front end of the diaphragm unit 1231, and the voice coil 1234 is located at the rear end of the diaphragm unit 1231. The weight layer 1232 is located in the center of the diaphragm unit 1231 to slow down the vibration frequency of the vibration assembly 123, thereby enhancing low-frequency sound output.

[0072] In this embodiment, the weight layer 1232 is annular. That is, when the weight layer 1232 is placed on the diaphragm unit 1231, the center of the weight layer 1232 exposes the diaphragm unit 1231 to the outside. In other words, the diaphragm unit 1231 is suitable for vibrating the air at the corresponding exposed position.

[0073] In particular, the sound quality is enhanced by placing the weight layer 1232 on the diaphragm unit 1231. The weight layer 1232 is made of a metal material that is not magnetically attracted, thus preventing interference with the magnetic field provided by the magnetic return assembly 122. When the diaphragm unit 1231 vibrates, its vibration is transmitted to the weight layer 1232. Due to the material of the weight layer 1232, a heavy, metallic bass effect is produced, thereby compensating for the bass and improving the sound quality of the semi-open headphone 1.

[0074] By setting the counterweight layer 1232 in the central area of ​​the diaphragm unit 1231, the amplitude of vibration is reduced, so that the area with the counterweight layer 1232 provides low-frequency sound effects; the area without the counterweight layer 1232 generates micro-vibration to provide mid- and high-frequency sounds.

[0075] Therefore, the arrangement of the sound-speaker component 12 ensures that the semi-open earphone 1 has high-quality output covering the entire range of low, medium and high frequencies, making it more competitive than traditional wireless earphones.

[0076] In this embodiment, the shape of the speaker member 12 is a shuttle or ellipse, which increases the corresponding speaker size to enhance the sound effect and fits the overall shape of the in-ear speaker 10 .

[0077] In this embodiment, more specifically, as shown in Figures 3 and 4, the diaphragm unit 1231 is elliptical, and has narrowed portions at both ends close to and away from the ear canal 94. This maintains the area of ​​the diaphragm unit 1231 and facilitates the insertion of the in-ear speaker 10 into the ear canal 94.

[0078] The speaker housing 11 forms the end surface 101, the second side surface 102, and the third side surface 103 of the in-ear speaker 10. In this embodiment, the speaker member 12 is arranged facing the third side surface 103. When the in-ear speaker 10 is inserted into the ear canal 94, the sound-emitting surface of the diaphragm unit 1231 of the speaker member 12 does not face the ear canal 94, but faces the third side surface 103 of the in-ear speaker 10 and the auricle 93.

[0079] In addition, it is worth mentioning that the earphone frame of the semi-open earphone 1 includes a functional connection body 31, an extension connection part 20 and a speaker body 11, and its material can be various metal materials, such as aluminum, titanium, copper, silver, gold, zinc alloy and stainless steel, and can be produced by powder casting, sand casting or 3D printing.

Furthermore, when the semi-open earphone 1A is in the wearing state, the extension body 21A is located in front of the user's auricle 93. The extension body 21A is close to the user's auricle 93, but does not fit the user's auricle 93. In other words, the extension body 21A remains suspended in front of the user's auricle 93.

[0083] In another embodiment of the present invention, at least one groove may be provided on the outer surface of the extended connection portion 20A to connect the sound receiving cavity 14 and the functional cavity 36. At least one wire is suitable for connecting through the groove. The speaker component 12 is suitable for being electrically connected to the power supply component 33 and the functional component 32 through the wire. Furthermore, the wire connection is arranged on the outside of the speaker connection portion 20A, and when the semi-open earphone 1A is in a wearing state, the wire is visible to the outside. The user can choose the color of the wire according to his or her preferences to meet the user's personalized fashion needs when the semi-open earphone 1 is in a wearing state.

[0084] Figures 9 and 10 illustrate a semi-open earphone 1B according to a second preferred embodiment of the present invention. The semi-open earphone 1B comprises an in-ear speaker 10B, an extended connector 20B, and a behind-the-ear functional portion 30B. The in-ear speaker 10B, the extended connector 20B, and the behind-the-ear functional portion 30B are interconnected. In other words, the semi-open earphone 1B comprises a three-part structure consisting of the in-ear speaker 10B, the extended connector 20B, and the behind-the-ear functional portion 30B.

[0085] The in-ear speaker portion 10B is adapted to provide a sound output function. The extended connection portion 20B is adapted to provide a connection, clamping, and fixing function.
