Description

Technical Field

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

[0002] Smart wearable technology has changed our lifestyle, and the most remarkable example is the earphone. For young people in the AI era, earphones are so common that we hardly realize the reasons why people rely on them more and more with the development of the times. It is not only because they are sound transmitters, but also because they endow the wearer with the ability to be independent and create subjective reality. More importantly, with the disappearance of the boundary between work and social life, earphones have become important modern mediators between public and private spaces.

[0003] As for the earphone itself, long-term wearing has certain damages to the body. When using earphones to answer calls or listen to music for a long time, since the eardrum is very close to the vibrating piece of the earphone, the sound wave conduction range is small and concentrated, which causes relatively large stimulation to the auditory nerve of the eardrum and is likely to cause dizziness, tinnitus, hearing loss, diplacusis, etc. If you listen continuously for several or even more than a dozen hours, sudden deafness may also occur. Earplugs can cause chronic irritation to the external auditory canal and cause ear inflammation. In addition, if you wear earphones for too long, your spirit will always be in a tense state, which is also not conducive to health.

[0004] Most traditional earphones directly block the user's ear canal in an in-ear manner, 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, it causes pain from wearing earphones for a long time and is also likely to cause a decline in the hygiene of the user's ear canal. On the other hand, it is easy for the user to not hear the external sounds clearly during the wearing process, which has certain potential safety hazards.

[0005] Traditional bone conduction earphones are known to the general public for their characteristics of not causing pain after long-term wearing and protecting the ears. Although traditional bone conduction earphones bypass the user's ear canal, the music does not enter the ear and does not pass through the user's eardrum, but the tone quality of bone conduction earphones is poor. Since it is transmitted through the skin and bones and then to the ossicles, the separation and restoration of the song are poor, and there are also problems of sound leakage and lack of immersion.

[0006] Traditional earphones usually use dynamic loudspeakers, and the output sound effects of dynamic loudspeakers are better in the performance of medium and high frequencies, and it is impossible to achieve excellent performance in the bass sound range.

[0007] How to simultaneously solve the problems of not feeling tired after long-term wearing of wireless Bluetooth earphones, portable wearing, sound quality preservation and sound effect preservation is an urgent problem to be solved nowadays. Summary of the Invention

[0008] One advantage of the present invention is to provide a semi-open earphone. The semi-open earphone contacts the user's ear canal through the reduced-size earplug part, avoiding the feeling of pressure on the user, achieving a completely painless experience, and enabling long-term wearing without fatigue.

[0009] Another advantage of the present invention is to provide a semi-open earphone. One side of the semi-open earphone is worn by inserting it into the ear, which can extend to the inner side of the user's ear canal, with better sound output effect. At the same time, it will not block the user's ear canal, causing problems such as extrusion, unhygienic conditions, and blocked sound.

[0010] Another advantage of the present invention is to provide a semi-open earphone. The semi-open earphone is fixed on both sides of the user's auricle through a wearing method of fixing on both sides and clamping in the middle, avoiding loss.

[0011] Another advantage of the present invention is to provide a semi-open earphone. The shape of the semi-open earphone on the side close to the user's ear canal is spindle-shaped, wider in the middle and narrower at both ends, which is easy to be inserted into the user's ear canal without completely closing the ear canal, and can maintain a good sound effect without easily causing sound distortion.

[0012] Another advantage of the present invention is to provide a semi-open earphone. The shape of the semi-open earphone on the side close to the user's ear canal is strip-shaped, which is easy to be inserted into the user's ear canal without completely closing the ear canal, and can maintain a good sound effect without easily causing sound distortion.

[0013] Another advantage of the present invention is to provide a semi-open earphone. The semi-open earphone can be worn by fixing one side by inserting it into the ear and the other side against the user's ear back, and can be worn without falling off only by fixing on both sides.

[0014] Another advantage of the present invention is to provide a semi-open earphone. The semi-open earphone can enhance the intelligent dressing and decorative property by means of decoration such as setting diamonds on the outer surface.

[0015] Another advantage of the present invention is to provide a semi-open earphone. The semi-open earphone can adopt an adjustable clamping wearing method to expand the wearing audience group and adapt to customer groups of different age levels and ethnic differences.

[0016] Another advantage of the present invention is to provide a semi-open earphone. The shape of the semi-open earphone on the side far from the user's ear canal can tend to be larger. 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 to provide a semi-open earphone, which has better sound effect output in the bass range compared with traditional earphones.

[0018] Another advantage of the present invention is to provide a semi-open earphone, the sound effect output of which has a certain sense of heaviness and metallic texture, and the sound effect output is better, bringing a mechanical experience to the user.

[0019] Another advantage of the present invention is to provide a semi-open earphone, which can achieve stereo sound through the arrangement of sound holes while being worn in the ear.

[0044] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present invention can be applied to other implementation manners, variant schemes, improvement schemes, equivalent schemes, and other technical schemes without departing 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 orientation or positional relationship indicated by terms such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 construed as limitations on the present invention.

[0046] It can 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 can be one, and in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0047] As Figures 1 to 5 shown, a semi-open earphone 1 according to a preferred embodiment of the present invention is schematically shown. The semi-open earphone 1 is adapted to be worn on the ear of a user, one end is adapted to extend and enter the ear canal 94 of the user, and the other end abuts against and is located on the back side of the auricle 93, so as to achieve no fatigue after long-term wearing through the front wearing method of point contact, and ensure the output of sound effects through the front shape. Further, the semi-open earphone 1 straddles 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 side of the user's auricle 93.

[0048] For the sake of convenience of description, when the semi-open earphone 1 is located at the user's ear, the side towards which the user's ear canal faces is defined as the front side, and conversely, it is defined as the rear side.

[0049] The semi-open earphone 1 includes an in-ear speaker part 10, an extension connecting part 20, and a back-ear functional part 30. The in-ear speaker part 10, the extension connecting part 20, and the back-ear functional part 30 are connected to each other. That is to say, the semi-open earphone 1 is composed of three sections: the in-ear speaker part 10, the extension connecting part 20, and the back-ear functional part 30.

[0050] The in-ear speaker part 10 is adapted to provide the function of sound effect output. The extension connecting part 20 is adapted to provide the function of connection, clamping, and fixing. The back-ear functional part 30 is adapted to provide additional accessory functions. When the semi-open earphone 1 is in a worn state, the in-ear speaker part 10 approaches and extends deep into the user's ear canal 94, the extension connecting part 20 straddles the front and rear sides of the user's auricle 93 and bypasses the helix 92. The back-ear functional part 30 is located on the back side of the user's auricle 93.

[0051] Specifically, in this embodiment, the in-ear speaker part 10 is implemented as a shuttle shape. Due to the characteristics of the narrow ends and wide middle of the shuttle shape, when the in-ear speaker part 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 communicating with the outside world in the ear canal 94, so as to avoid causing pressure to the user, achieve painless wearing for a long time, and avoid damage to hearing due to the ear canal 94 being closed. The ear can also hear external sounds to avoid safety risks.

[0052] More specifically, as Figures 3 to 5 shown in, the in-ear speaker part 10 includes an end face 101 and has a first side face 102 and a second side face 103. The size of the end face 101 is smaller, while the first side face 102 and the second side face 103 are opposite and larger in size. When the in-ear speaker part 10 is inserted into the user's ear canal 94, its end face 101 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 user's auricle 93 respectively. The end face 101 is tapered to reduce the width dimension in the direction towards the user's ear canal 94, so as to facilitate the end of the in-ear speaker part 10 to be inserted into the user's ear canal 94.

[0053] The material of the extension connection part 20 is different from that of the in-ear speaker part 10 and the back-ear functional part 30. Further, the material of the extension connection part 20 is preferably a material with a certain degree of extensibility and flexibility. By folding and bending the extension connection part 20, the semi-open earphone 1 is fixedly worn on the user's ear. In other words, the user bends the extension connection part 20 to bring the in-ear speaker part 10 closer to the back-ear functional part 30. The user adjusts the bending degree of the extension connection part 20 to bring the semi-open earphone 1 closer to and fit snugly on the user's ear to complete the wearing. Through the adjustable wearing method, it can adapt to users of a wider age range and the size differences of ears caused by different ethnic groups. The wearing method is almost close to the user's ear, avoiding loss and reducing the use cost of the semi-open earphone 1.

[0054] The in-ear speaker part 10 is in a shuttle shape and extends into the user's ear canal 94. It outputs sound effects to the user in an in-ear manner. However, compared with traditional in-ear earphones, the in-ear speaker part 10 does not completely block the user's ear canal 94. On the one hand, it avoids the problem of wearing environmental hygiene caused by the in-ear wearing method. On the other hand, it reduces the discomfort caused by the increase in wearing time. The semi-open earphone 1 optimizes the original surface contact and becomes a partial contact with the user's ear, further reducing the contact area with the surface of the user's ear and reducing the squeezing feeling caused by pressing on the ear. As the wearing time increases, the pain caused by squeezing is significantly reduced.

[0055] The in-ear speaker part 10 includes a speaker housing 11, an ear-connecting main body 13, and a sound-collecting cavity 14. The speaker housing 11 and the ear-connecting main body 13 are installed and connected to each other, and the sound-collecting cavity 14 is formed between the speaker housing 11 and the ear-connecting main body 13. The ear-connecting main body 13 is integrally connected to the extension connection part 20. When the semi-open earphone 1 is in a worn state, the speaker housing 11 is located in the user's concha 91 and extends into the user's ear canal 94. The ear-connecting main body 13 is farther away from the user's ear canal 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 adapted to provide the function of sound effect output, and the speaker holes 15 are arranged on the speaker housing 11. The speaker component 12 is located between the speaker housing 11 and the ear-connecting main body 13. That is to say, the speaker component 12 is located in the sound-collecting cavity 14. When the semi-open earphone 1 is in a worn state, the speaker component 12 outputs sound effects to the user's ear canal from front to back. The speaker holes 15 are arranged on the side surface rather than the end surface of the speaker housing 11, and they do not face the user's concha 91.

[0057] That is to say, when traditional earphones are worn on the user's ears, their speakers are arranged facing the user's ear canal 94 and vibrate to produce sound. However, in the present invention, when the semi-open earphone is worn on the user's ears, the sound emitting member 12 and the sound emitting hole 15 are not in the vertical direction and do not face the user's ear canal 94, but face the inner wall of the ear canal 94. The extension connection part 20 includes an extension main body 21 and has a clamping space 22. One end of the extension main body 21 is connected to the in-ear sound emitting part 10, and the other end is connected to the back-ear functional part 30. In other words, the extension main body 21 is located between the in-ear sound emitting part 10 and the back-ear functional part 30. The extension main body 21 is adapted to provide the function of connecting and extending. When the semi-open earphone 1 is in the wearing state, the extension main body 21 straddles the front and back sides of the user's auricle 93. That is to say, the extension main body 21 bends and extends forward from the back side of the user's auricle 93 along the side of the auricle 93. During the bending process, the extension main body 21 approaches and adheres to the user's auricle 93 to adapt to the ear shapes of different people and facilitate wearing. The extension main body 21 is bent to enclose the clamping space 22. The clamping space 22 is adapted to accommodate the user's auricle 93. The clamping space 22 is adapted to change in real time according to the size of the user's ear to adjust the wearing comfort. When the in-ear sound emitting part 10 and the back-ear functional part 30 move away from each other, the clamping space 22 becomes larger; when the in-ear sound emitting part 10 and the back-ear functional part 30 approach each other, the clamping space 22 becomes smaller.

[0058] The clamping space 22 can be adjusted and changed, so that the user has a certain degree of convenience during the wearing process. For example, when the user is a group of deliverymen or couriers, generally, this user group has to drive a vehicle for a long time, listen to the navigation, answer orders and customer messages while also paying attention to the news of the external environment at all times. By wearing the semi-open earphone 1. Due to the structural characteristics of the spindle-shaped in-ear speaker 10, the semi-in-ear wearing method does not block the user's ear canal 94. At the same time, through the auxiliary clamping and fixing of the extension connection part 20, the loss of the earphone during driving is avoided. When reaching the predetermined delivery address, the semi-open earphone 1 can also be easily removed through the bendability of the extension connection part 20. On the one hand, the wearing method will not cause long-term extrusion of the user's ear canal, thereby avoiding the pain caused by compression. On the other hand, it can be stably clamped and freely removed, ensuring the wearing convenience and avoiding the damage to the user's hearing caused by long-term wearing.

[0059] The back ear functional part 30 includes a functional connection main body 31, a pair of functional cover bodies 34, and has a functional cavity 36. The functional connection main body 31 is integrally connected to the extension main body 21, and the functional cover bodies 34 are respectively adapted to be installed on both sides of the functional connection main body 31. A functional cavity 36 is formed between the functional cover body 34 and the functional connection main body 31. The functional cavity 36 is adapted to provide the function of storing energy information.

[0060] In this embodiment, the materials of the functional connection main body 31, the ear-leaning connection main body 13, and the extension main body 21 can optionally be made of the same material, preferably a material with better ductility, so that when the semi-open earphone 1 is in a wearing state, the user can easily pinch the earphone to change the relative positional relationship between the functional connection main body 31, the ear-leaning connection main body 13, and the extension main body 21. By changing the relative positional relationship between the functional connection main body 31, the ear-leaning connection main body 13, and the extension main body 21, the size of the clamping space 22 is changed to adapt to the shape of the user's ear, so as to achieve a tight fit, and through the adjustable clamping space 22, it is easy to pick up.

[0061] The back ear functional part 30 further includes a functional component 32 and a power supply component 33. The functional component 32 is adapted to provide the function of information processing, the power supply component 33 is adapted to provide the function of energy supply, and 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. Further, the functional component 32 and the power supply component 33 are also electrically connected to the speaker component 12. That is to say, the speaker component 12 is electrically connected to the power supply component 33 through the functional component 32. Further, the information received and processed by the functional component 32 is transmitted to the speaker component 12, and the speaker component 12 converts the electrical signal into a sound signal and outputs the sound effect to the user's ear canal through the sound hole 15.

[0062] The back ear functional part 30 further includes at least one charging contact 35. In this embodiment, the number of the charging contacts 35 is two in real time. The charging contacts 35 are arranged on the functional cover body 34. One end of the charging contact 35 is connected to the power supply component 33, and the other end extends and protrudes from the functional cover body 34. The semi-open earphone 1 performs external energy supply through the charging contacts 35. That is to say, the power supply component 33 is adapted to perform external energy supply through the charging contacts 35. In other words, when the semi-open earphone 1 is not in use, the user can charge and supply by contacting the charging contacts 35 with an external power supply.

[0063] It is worth mentioning that when the semi-open earphone 1 is in a worn state, the back-ear functional part 30 is located on the dorsal side of the user's auricle 93 and is far from the user's concha 91. In terms of manufacturing process, the shape of the back-ear functional part 30 can be made to be relatively large. In other words, the shape of the back-ear functional part 30 is large. Furthermore, the power component 33 located inside the functional cavity 36 can be large. With the power component 33 of a large capacity, the battery life of the semi-open earphone 1 can be improved. When the user works outdoors for a long time and must often have functions such as navigation, etc., there is no need to frequently charge the semi-open earphone 1 additionally. The semi-open earphone 1 can be worn for long-term signal reception and positioning simulation, and it can be applicable to a wide range of audiences.

[0064] Compared with the dynamic coil speaker of traditional wireless Bluetooth earphones, the sound effect output in the medium and high frequency ranges is better, but the good sound effect output in the low frequency range has always been unable to be overcome. For the speaker component 12 of the semi-open earphone 1 in this embodiment, the speaker component 12 can achieve a better sound effect output in the low frequency range, making the output sound effect heavier and having a good sound quality experience according to the mechanical texture.

[0065] Specifically, the speaker component 12 includes a mounting component 121, a magnetic circuit component 122, and a vibration component 123. The mounting component 121, the magnetic circuit component 122, and the vibration component 123 are installed with each other. The mounting component 121 is suitable for providing the functions of hardness support and installation space. The magnetic circuit component 122 is suitable for providing the function of electromagnetic conversion. The vibration component 123 is suitable for providing the function of sound effect output. The magnetic circuit component 122 is installed inside the mounting component 121, and the vibration component 123 is installed on the front end face of the mounting component 121. The magnetic circuit component 122 and the vibration component 123 are combined together to achieve electro-acoustic conversion.

[0066] The mounting component 121 includes a housing 1211 and a cavity 1212. The housing 1211 provides external hardness support, and the cavity 1212 is suitable for providing installation space. The housing 1211 surrounds and forms the cavity 1212.

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

[0068] The vibration assembly 123 includes a diaphragm unit 1231, a weight layer 1232, a superimposed 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 superimposed layer 1233 are disposed on the diaphragm unit 1231. The voice coil unit 1234 surrounds 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 member 32 to provide an input driving current to generate an electromagnetic field, and interact with the magnetic field of the magnetic return assembly 122 so that the voice coil unit 1234 is driven to perform reciprocating motion, and the voice coil unit 1234 drives the diaphragm unit 1231 to vibrate, thereby realizing sound effect output.

[0069] In this embodiment, the diaphragm unit 1231 is optionally implemented as a plastic material, and the superimposed layer 1233 is optionally made of a metal material. The superimposed layer 1233 is suitable for providing a metallic texture of the sound effect, and the weight layer 1232 is suitable for providing a heavy texture of the sound effect to realize the sound effect output in the low frequency range. The superimposed layer 1233 is attached to the diaphragm unit 1231. By setting the superimposed layer 1233 on the flexible diaphragm unit 1231, the diaphragm unit 1231 is tightened and its rigidity is increased, and a certain amount of elasticity is reduced, thereby increasing the vibration frequency, improving the sound quality and sound effect, and reducing the distortion rate.

[0070] In this embodiment, the superimposed layer 1233 is implemented as a mesh structure. The superimposed layer 1233 is distributed in a planar shape, and partial holes or grooves are implemented on the surface of the superimposed layer 1233, so that part of the diaphragm unit 1231 is exposed at the position corresponding to the holes or grooves, thereby enabling the diaphragm unit 1231 to agitate air. In this embodiment, the superimposed layer 1233 further includes an annular layer 12331 and a sheet layer 12332. The annular layer 12331 is implemented as a plurality of concentric circles surrounding from the outside to the inside, and the sheet layer 12332 is located inside the annular layer 12331.

[0071] The weight layer 1232 is disposed in the central region of the superimposed layer 1233, that is to say, the superimposed layer 1233 surrounds the weight layer 1232. The weight layer 1232 is located on the front end face of the diaphragm unit 1231, and the voice coil 1234 is located on the rear end face of the diaphragm unit 1231. The weight layer 1232 is located in the central region of the diaphragm unit 1231 to slow down the vibration frequency of the vibration assembly 123, thereby enhancing the sound effect output in the low frequency range.

[0072] In this embodiment, the counterweight layer 1232 is annular. That is to say, when the counterweight layer 1232 is disposed on the diaphragm unit 1231, the center of the counterweight layer 1232 exposes the diaphragm unit 1231 to the outside. That is to say, the diaphragm unit 1231 is adapted to agitate air to generate vibration through the exposed position at the corresponding position.

[0073] Specifically, the counterweight layer 1232 is disposed on the diaphragm unit 1231 to improve the sound quality. The counterweight layer 1232 is implemented as a metal material that is not attracted by magnetic force, avoiding interference with the magnetic field provided by the magnetic return assembly 122. When the diaphragm unit 1231 vibrates, its vibration is transmitted to the counterweight layer 1232. Due to the material of the counterweight layer 1232, a thick metallic bass effect is generated, thereby compensating for the bass and improving the sound quality of the semi-open earphone 1.

[0074] By the counterweight layer 1232 disposed in the central region of the diaphragm unit 1231, the amplitude of vibration is reduced, so that the region with the counterweight layer 1232 provides low-frequency sound effects; the region without the counterweight layer 1232 generates micro-vibrations to provide medium and high frequencies.

[0075] Thus, through the setting of the speaker component 12, it is ensured that the semi-open earphone 1 provides high-quality output within the full sound range covering low, medium, and high frequencies. It is more competitive than traditional wireless earphones.

[0076] In this embodiment, the implemented shape of the speaker component 12 is spindle-shaped or oval. On the one hand, the corresponding speaker size is increased to enhance the sound effect. On the other hand, it is to fit the overall shape of the in-ear speaker part 10.

[0077] In this embodiment, more specifically, as Figure 3 and Figure 4 stated, the diaphragm unit 1231 is oval, and it has reduced portions at two ends close to and far from the ear canal 94, so that the area of the diaphragm unit 1231 is maintained and it is convenient for the in-ear speaker part 10 to be inserted into the ear canal 94.

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

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

[0081] Specifically, the semi-open earphone 1A further includes an externally embedded decoration part 40A. In this embodiment, the externally embedded decoration part 40A is optionally implemented on the extended connection part 20A or the back ear functional part 30A. In this embodiment, the externally embedded decoration part 40A can be implemented in a mode such as inlaying diamonds. The externally embedded decoration part 40A is externally visible, making the semi-open earphone 1A have a certain decorative effect. When the semi-open earphone 1A is in a worn state, the externally embedded decoration part 40A is externally visible to meet the personalized fashion needs of users. Users can also select the shape of the externally embedded decoration part 40A they like according to their own preferences to inlay and decorate the extended connection part 20A and the back ear functional part 30A. Further, the externally embedded decoration part 40A is disposed on the front end face of the extended main body 21A and the side surface of the back ear functional part 30A. In another embodiment of the present invention, the externally embedded decoration part 40A can also be inlaid on the outer surface of the back ear functional part 30A. Thus, the installation position of the externally embedded decoration part 40A is not limited by the present invention.

[0082] It is worth mentioning that in this embodiment, the semi-open earphone 1A includes an extended connection part 20A. The extended connection part 20A includes an extended main body 21A and has a clamping space 22A, and the clamping space 22A is formed by being surrounded by the extended main body 21A. In this embodiment, the extended main body 21A straddles the front and back end faces of the user's auricle 93. Further, when the semi-open earphone 1A is in a worn state, the extended main body 21A is located on the front side of the user's auricle 93. The extended main body 21A is close to the user's auricle 93 but does not fit closely to the user's auricle 93. In other words, the extended main body 21A maintains a suspension on the front side of the user's auricle 93.

[0083] In another embodiment of the present invention, at least one groove may be formed on the outer surface of the extension connection part 20A to communicate the sound receiving cavity 14 and the function cavity 36. At least one wire is adapted to pass through the groove for connection. The speaker component 12 is adapted to be electrically connected to the power supply component 33 and the function component 32 through the wire. Further, the wire is arranged outside the speaker connection part 20A, and when the semi-open earphone 1A is in a worn state, the wire is exposed outside. The user can select the color of the wire according to his or her preference to meet the personalized fashion needs of the user when the semi-open earphone 1 is in a worn state.

[0084] As Figures 9 to 10 Shown is a semi-open earphone 1B according to the second preferred embodiment provided by the present invention. The semi-open earphone 1B includes an in-ear speaker part 10B, an extension connection part 20B, and a back-ear function part 30B. The in-ear speaker part 10B, the extension connection part 20B, and the back-ear function part 30B are connected to each other. That is to say, the semi-open earphone 1B is composed of three parts: the in-ear speaker part 10B, the extension connection part 20B, and the back-ear function part 30B.

[0085] The in-ear speaker part 10B is adapted to provide the function of sound effect output. The extension connection part 20B is adapted to provide the function of connection and clamping fixation.
