Description

Semi-open headphones with sound-enhancing speaker components Technical Field

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

[0002] The most important part of a headset is the driver. In our daily life, the most common drivers are: dynamic driver, balanced armature driver, planar driver, and electrostatic driver. The dynamic driver is currently the most widely used and the technology is relatively mature.

[0003] Dynamic headphones are the most common and widely used type of headphones. Their driver is essentially a small dynamic speaker. A voice coil in a permanent magnetic field drives the vibrations of a connected diaphragm. Driven by the signal current, the coil drives the diaphragm to produce sound. Dynamic headphones are often used to drive the headphone outputs on speakers. However, their disadvantage is that they are limited to mid-to-high-frequency audio and cannot meet the requirements of the low-frequency range. Traditional dynamic headphones produce sound by driving the diaphragm. However, due to the unique arrangement of the coils, the voice coil vibrates, and the vibrations are transmitted to the diaphragm. The diaphragm vibrates first where it contacts the voice coil, and then this vibration spreads to the center and edges of the flexible diaphragm. This transmission process is asynchronous, resulting in split vibrations. To a certain extent, this can lead to a decrease in sound quality.

[0004] Summary of the Invention

[0005] One advantage of the present invention is that it provides a semi-open headphone that can provide sound output of a full audio range.

[0006] Another advantage of the present invention is that it provides a semi-open headphone that has a better low-frequency sound output effect than a traditional headphone.

[0007] Another advantage of the present invention is that it provides a semi-open earphone, which achieves the goal of not getting tired of listening or wearing for a long time through the sound generation principle of a speaker component.

[0008] Another advantage of the present invention is the provision of semi-open headphones. These semi-open headphones, through the sound generation principle of the speaker assembly, achieve high resolution, resulting in better mid- and high-frequency performance and significant bass performance, while also being relatively affordable and easily marketable. Another advantage of the present invention is the provision of semi-open headphones. During sound generation, the vibration of the planar diaphragm is transmitted to a counterweight plate, producing a heavy, metallic bass effect, thereby enhancing the sound quality of the headphones.

[0009] Another advantage of the present invention is that it provides a speaker assembly that is suitable for being installed in any earphone, has a wide range of applications, has strong adaptability, and the installation position is not limited by the installation carrier.

[0010] Another advantage of the present invention is that it provides a semi-open headphone that is painless to wear and suitable for long-term wear.

[0011] Another advantage of the present invention is that it provides a semi-open earphone. When the semi-open earphone is worn, the sound-emitting part is hung in the user's antitragus, which will not cause squeezing or compression on the user's ear canal, thereby avoiding hearing damage to the user during use.

[0012] Another advantage of the present invention is that it provides semi-open headphones, in which the planar diaphragm of the plastic material of the diaphragm component has its rigidity increased by adding a metal superimposed layer, so that the vibration response speed of the diaphragm component is faster and the vibration directionality generated is stronger, thereby having high sound resolution and being able to restore the recorded sound as realistically as possible, producing a high-fidelity sound quality effect reaching the monitoring level.

[0013] Another advantage of the present invention is that it provides a semi-open earphone, wherein the structure of the diaphragm component can reduce the airflow generated by the diaphragm component when it vibrates, thereby reducing the impact on the eardrum, and when the semi-open earphone is worn, no completely closed space is formed between the sound-emitting part and the eardrum, thereby further reducing the impact of the airflow on the eardrum, so that the semi-open earphone can avoid hearing damage to the user when listening in the near field, thereby protecting the user's hearing.

[0014] Another advantage of the present invention is that it provides a semi-open earphone, wherein the diaphragm component allows for the use of an amplifier without the need for an amplifier and can provide better sound quality effects at lower sound pressures. Therefore, when the diaphragm component is applied to the semi-open earphone, it can operate at lower sound pressures, thereby reducing damage to the user's hearing, so that the semi-open earphone is suitable for long-term wear and can protect the user's hearing.

[0015] Another advantage of the present invention is that it provides semi-open headphones. When worn, the semi-open headphones have a certain decorative effect on the user's ears. When used as headphones, they also function as earrings. When the headphones are not used to listen to sound effects, they can still be worn on the ears as decorations.

[0016] Another advantage of the present invention is that it provides a semi-open earphone, which, through a semi-open wearing manner, does not shield external environmental sounds while listening to the sounds from the earphone, thereby avoiding safety hazards.

[0017] Another advantage of the present invention is that it provides semi-open headphones, which are made of hard materials or materials with high ductility. The relative positions of the two ends have strong plasticity and can be adaptively worn and fixed by users of different age groups. They are not easy to be lost and are suitable for a wider user group.

[0018] Another advantage of the present invention is that it provides semi-open headphones. Compared with traditional headphones, the semi-open headphones disperse the sound output units that were originally centrally distributed. In terms of manufacturing process, the sound effect components located on the side of the user's concha cavity during wearing can be larger in size, thereby enhancing the sound output effect.

[0019] Another advantage of the present invention is that it provides a semi-open earphone, which has a variety of additional functional extensions, such as: hearing assistance, voice reminders, intelligent voice interaction, etc.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] As shown in Figures 1 to 4, a semi-open earphone 1 according to a preferred embodiment of the present invention is schematically shown. The semi-open earphone 1 is suitable for being worn on the ear of a user and outputting sound effects into the ear canal of the user through electroacoustic conversion.

[0058] For ease of explanation, when the semi-open earphones 1 are worn on the user's ears, the direction of the user's earlobe 92 is defined as forward, and the direction of the antitragus 93 above the user's earlobe 92 is defined as upward, and the direction of the antitragus 93 above the user's earlobe 92 is defined as downward.

[0059] The semi-open earphone 1 includes an ear-speaker portion 10, a connecting portion 20, and a functional portion 30. The ear-speaker portion 10, the connecting portion 20, and the functional portion 30 are interconnected. One end of the connecting portion 20 is connected to the ear-speaker portion 10, and the other end is connected to the functional portion 30. When the semi-open earphone 1 is worn, the ear-speaker portion 10 is located in the user's cavum concha 91, the connecting portion 20 extends from the upper end of the user's antitragus 93 from top to bottom across the user's earlobe 92, and the functional portion 30 is located on the back of the user's earlobe 92.

[0060] The ear-speaker portion 10 has the function of providing sound output, the connecting portion 20 has the function of connection and decoration, and the functional portion 30 has additional functions, such as energy supply, charging endurance, hearing aid function, intelligent voice interaction and the like.

[0061] It's worth noting that, unlike traditional headphones, the ear-facing speaker 10 of the semi-open headphone 1 doesn't directly insert into the user's ear canal. Instead, it hangs within the user's antitragus 93 and is confined to the user's cavum concha 91. Compared to traditional headphones, this avoids the hygienic issues and reduced user experience associated with prolonged ear canal use, achieving the goal of pain-free wear. It also prevents debris from clogging the surface of the ear-facing speaker 10, which could cause unsanitary conditions and make cleaning difficult.

[0062] Similarly, the ear-speaker portion 10 is hung in the user's concha cavity 91 and is clamped on the user's earlobe by the connecting portion 20 having a certain degree of ductility. This makes the wearing of the semi-open earphones 1 have a certain degree of stability. In this embodiment, the connecting portion 20 is preferably formed of a material with strong ductility, and the connecting portion 20 can ductilely bring the ear-speaker portion 10 and the functional portion 30 closer to each other. The ear-speaker portion 10 and the functional portion 30 are clamped and fixed to the user's ear by the ductility of the material of the connecting portion 20 itself. Compared with traditional earphones, loss, falling off and instability caused by the user's movement during wearing are avoided.

[0063] Furthermore, the connecting portion 20 in this embodiment is implemented as a fork from top to bottom that surrounds the user's earlobe 92 and extends backward to connect to the functional portion 30. The connecting portion 20 has a certain decorative effect. The shape of the connecting portion 20 is not limited by the present invention. The connecting portion 20 can be in various shapes, and only serves to connect the ear-closed sound-speaking portion 10 and the functional portion 30, and surrounds the front and rear end surfaces of the user's earlobe 92 to clamp and fix it. Users can choose different connecting portions 20 according to their own preferences, and they can play a decorative role during wearing to meet personalized fashion needs.

[0064] The functional unit 30 has additional functional features, and the user can use the functional unit 30 to realize functions such as charging and battery life, hearing aid function, and intelligent voice interaction of the entire device.

[0065] In particular, compared to traditional headphones, the functional portion 30 is separated from the ear-speaker portion 10, and unlike a centralized arrangement of functional components, the semi-open headphone 1 can have a larger structural shape of the functional portion 30 in the manufacturing process. On the one hand, the functional portion 30 is located on the back of the user's earlobe 92 during wear, and the larger functional portion 30 does not affect the wearing aesthetics of the semi-open headphone 1. On the other hand, the larger functional portion 30 can carry a larger energy endurance component than a smaller functional portion 30, thereby improving the sustainable use of the semi-open headphone 1. In other words, the standby time of the semi-open headphone 1 is improved, and the user can achieve sound output through the semi-open headphone 1 for a longer period of time.

[0066] In addition, since the wearing method of the semi-open earphones 1 is not limited to the user's ear canal, the volume size of the ear-closed sound speaker 10 can be larger, and the larger volume of the ear-closed sound speaker 10 can achieve an improvement in sound quality. Through the wearing method of the semi-open earphones 1, the ear-closed sound speaker 10 is hung on the inner side of the user's anti-auricular 93. The problem of the lack of privacy of the sound effects during the sound output process is avoided. Similarly, the ear-closed sound speaker 10 is close to and close to the user's ear canal, so that the semi-open earphones 1 will not affect people outside during the wearing process, and will not completely block the outside sounds during the process of listening to the sound output.

[0067] The ear-closed speaker part 10 includes a first housing 11, a first cover 12, a speaker assembly 14, and a sound receiving cavity 13. The first housing 11 is integrally connected to the connecting part 20, and the first cover 12 is installed on the first housing 11. The first housing 11 and the first cover 12 surround and form the sound receiving cavity 13. The speaker assembly 14 is installed in the sound receiving cavity 13. In other words, the speaker assembly 14 is installed between the first housing 11 and the first cover 12. Compared with the existing technology, the sound output of the speaker assembly 14 is better, and can achieve full-range coverage of low, medium and high frequencies. At the same time, the sound output resolution of the speaker assembly 14 is relatively large, so that the user will not feel a strong sense of fatigue during the process of wearing and listening. The semi-open earphones 1 have the function of not getting tired after listening for a long time.

[0068] Specifically, the speaker assembly 14 includes a housing member 141, an electromagnetic member 142, and a diaphragm member 143. The housing member 141 is adapted to provide an installation space, and the electromagnetic member 142 and the diaphragm member 143 are mounted on the housing member 141. The housing member 141 provides an installation function, the electromagnetic member 142 provides an electromagnetic drive function, and the diaphragm member 143 is adapted to provide a sound output function. The diaphragm member 143 is located at the front end relative to the electromagnetic member 142, so that the sound generated by the diaphragm member 143 is output forward.

[0069] The housing member 141 includes a shell 1411 and a chamber 1412. The shell 1411 provides an installation space, and the chamber 1412 provides a space for gas flow. The electromagnetic member 142 is installed at the rear end of the shell 1411, and the diaphragm member 143 is covered and installed on the front end of the shell 1411. In other words, the rear end of the chamber 1412 is closed, and the front end is open to the diaphragm member 143.

[0070] The electromagnetic member 142 includes a magnet 1421 and a first circuit board 1422. The magnet 1421 is disposed on the front side of the rear end face of the housing 1411, and the first circuit board 1422 is mounted on the rear side of the rear end face of the housing 1411. In other words, the magnet 1421 is located inside the chamber 1412, and the first circuit board 1422 is located outside the chamber 1412. In other words, the magnet 1421 and the first circuit board 1422 are located on the front and rear sides of the rear end face of the housing 1411, respectively.

[0071] In this embodiment, the magnet 1421 is implemented as a permanent magnet, and the magnet 1421 is suitable for providing a magnetic field. The magnet 1421 is arranged on the rear side of the diaphragm member 143 to provide an electromagnetic force. The first circuit board 1422 is implemented to provide the diaphragm member 143 with an electromagnetic force.

[0072] The diaphragm component 143 includes a planar diaphragm 1431, a counterweight plate 1432 and at least one metal stacking layer 1433. The planar diaphragm 1431 is suitable for being covered on the front end surface of the shell 1411. The planar diaphragm 1431 is suitable for covering the front side of the cavity 1412. The planar diaphragm 1431 is suitable for providing vibration to produce sound output. The counterweight plate 1431 is installed on the front side of the planar diaphragm 1431, and the position of the counterweight plate 1431 corresponds to the position of the magnet 1421. The metal stacking layer 1433 is arranged on the front end surface of the planar diaphragm 1431. Furthermore, the counterweight plate 1431 is arranged at the center of the planar diaphragm 1431, and the metal stacking layer 1433 is arranged on the circumference of the planar diaphragm 1431. That is, the metal stacking layer 1433 is arranged on the circumference of the counterweight plate 1431. In other words, the counterweight plate 1431 is arranged at the center of the metal stacking layer 1433 .

[0073] The planar diaphragm 1431 has a central region 14311 and an outer region 14312. The central region 14311 is located at the center of the outer region 14312. In this embodiment, the central region 14311 is implemented as a centrally located circular region, while the outer region 14312 is implemented as an annular region extending away from the center. The metal overlay 1433 is located in the outer region 14312, and the counterweight plate 1432 is located in the central region 14311.

[0074] It is worth mentioning that in this embodiment, the counterweight plate 1431 is implemented as a circular plate. The magnets 1421 are symmetrically arranged on the counterweight plate 1431 located in the central area 14311. In other words, the center of the magnet 1421, the center of the central area 14311, and the center of the counterweight plate 1431 are located on the same axis.

[0075] Compared to existing technologies, the weight plate 1431 increases the weight of the planar diaphragm 1431, thereby changing the audio frequency emitted by the diaphragm member 143. The electromagnetic member 142 also includes a plurality of terminals 1423. In this embodiment, there are four terminals 1423 located on the rear end of the housing 1411. Two of these terminals 1423 are electrically connected to the metal stack 1433 to provide power. The other two terminals 1423 are electrically connected to the first circuit board 1422 to provide signal processing.

[0076] The arrangement of the dotted metal overlay 1433 in the outer edge region 14312, influenced by the magnetic field of the magnet 1421 located at the rear side of the cavity 1412, promotes vibration of the planar diaphragm 1431, ultimately producing sound output from back to front. Compared to traditional sound output modes, the addition of the counterweight plate 1432 shifts the sound output range of the planar diaphragm 1431 from the original mid-high frequencies to a system where low, mid-high frequencies are distributed in different regions. The placement of the counterweight plate 1432 increases the weight of the planar diaphragm 1431, indirectly reducing its vibration amplitude. Specifically, the planar diaphragm 1431 and the counterweight plate 1431 in the center region 14311 are suitable for emitting low-frequency sounds, while the planar diaphragm 1431 and the metal overlay 1433 in the outer edge region 14312 are suitable for emitting mid-high frequencies.

[0077] In this embodiment, the counterweight plate 1431 is made of a metal that is not magnetically attracted, such as copper or stainless steel. This allows for better bass, resulting in the semi-open earphones 1 having better sound quality than existing earphones. Existing earphones are unable to address the low-frequency sound quality. When the sound produced by the vibrating planar diaphragm 1431 strikes the counterweight plate, a heavy, metallic bass effect is produced, thereby compensating for the low frequencies and improving the sound quality of the semi-open earphones 1.

[0078] In particular, the speaker assembly 14 can achieve the same sound effect or even better than the existing sound through the micro-vibration generated by the current and the magnetic field. Compared with the existing speaker device, it saves magnets and diaphragms, has low cost and is easy to promote.

[0079] The ear speaker 10 has a plurality of sound receiving holes 15 , which are provided in the first cover 12 and at the end surface of the first cover 12 . The speaker assembly 14 is adapted to emit sound through the shrinking sound receiving holes 15 .

[0080] The connecting portion 20 includes a connecting body 21 and a clamping space 22. The connecting body 21 is integrally connected to the first compartment 11, and the connecting body 21 has a certain degree of ductility. The connecting body 21 is foldable. When the semi-open earphones 1 are worn, the connecting body 21 spans the front and rear ends of the user's earlobe 92. The two sides of the connecting body 21 are close to each other and form the clamping space 22, and the user's earlobe 92 is suitable for being located in the clamping space 22. In other words, the semi-open earphones 1 are clamped to the user's ears through the clamping space 22.

[0081] The functional portion 30 includes a second compartment 31 and a second cover 32, and has a functional cavity 33. The second compartment 31 is integrally connected to the connecting body 21, and the second cover 32 is mounted on the second compartment 31, forming the functional cavity 33 between the second compartment 31 and the second cover 32. When the semi-open earphones 1 are worn, the second compartment 31 and the second cover 32 are located on the back of the user's earlobe 92.

[0082] The connecting portion 20 also has at least one wire opening groove 23, and the wire opening groove 23 is arranged on the connecting body 21. The wire opening groove 23 is connected to the sound receiving cavity 13 and the functional cavity 33. A wire 24 is suitable for being arranged in the wire opening groove 23, and the wire 24 extends from the sound receiving cavity 13 to the functional cavity 33 along the wire opening groove 23. In this embodiment, the wire 24 can be optionally implemented as an internal luminous light strip with a transparent outer surface. When the semi-open earphones 1 are in the wearing state, the wire 24 is located in the wire opening groove 23 and is visible. Users can choose the wires 24 of different colors to meet their personalized fashion needs according to their preferences.

[0083] The functional portion 30 includes a second circuit board 34, a power supply 35, a microphone unit 36, and at least one charging contact 37. The second circuit board 34 and the power supply 35 are disposed within the functional cavity 33. The microphone unit 36 ​​and the charging contact 37 are disposed on the outer surface of the second cover 32. The second circuit board 34 is adapted to provide additional functions, the power supply 35 has an energy supply function, the microphone unit 36 ​​is adapted to provide a voice interaction function, and the charging contact 37 is adapted to provide external energy supply. The power supply 35 is electrically connected to the second circuit board 34. The microphone unit 36 ​​is electrically connected to the second circuit board 34.

Furthermore, the power supply 35 is electrically connected to the first circuit board 1422 and the metal stack 1433 via the terminal 1423.

[0084] In this embodiment, the microphone unit 36 ​​can be implemented as a sound generator for hearing aid functions and intelligent voice interaction functions. The microphone unit 36 ​​is electrically connected to the second circuit board 34, so that the semi-open earphones 1 can provide hearing aid and intelligent voice interaction functions to the user through the microphone unit 36.

[0085] In particular, the semi-open earphone 1 further includes at least one decorative unit 40. In the present embodiment, the decorative unit 40 is provided at the connecting portion 20. In another embodiment, the decorative unit 40 is suitable for being located at the ear-closed speaker portion 10 or the functional portion 30. The decorative unit 40 is externally visible on the semi-open earphone 1 to provide a decorative and beautifying effect, and thus the installation position of the decorative unit 40 is not limited by the present invention. Specifically, the decorative unit 40 is located at the lower end of the connecting portion 20. When the semi-open earphone 1 is worn on the user's ear, the connecting portion 20 is located at the user's earlobe 92, and the decorative unit 40 is arranged from top to bottom from the user's earlobe. It plays the role of decorating the earlobe 92 to meet the user's personalized needs. The user can replace and select the ear ornament unit 40 according to his or her preferences.

[0086] As shown in Figures 4A to 4F, a speaker assembly 14 and a diaphragm member 143 thereof according to a variant embodiment of the above-mentioned embodiment of the present invention are illustrated, and the speaker assembly 14 is suitable for being installed in an earphone 9. The speaker assembly 14 is suitable for providing electroacoustic conversion and emitting sound effects. In this embodiment, the speaker assembly 14 includes a shell member 141, an electromagnetic member 142 and the diaphragm member 143. The shell member 141 is suitable for providing an installation space. The electromagnetic member 142 is suitable for providing energy drive and supply, and the diaphragm member 143 is suitable for providing sound output. The electromagnetic member 142 and the diaphragm member 143 are combined together to provide electroacoustic conversion.

[0087] The outer shell component 141 includes a shell 1411 , which provides an installation space. The electromagnetic component 142 is installed at the rear end of the shell 1411 , and the diaphragm component 143 is covered and installed on the front end surface of the shell 1411 .

[0088] The electromagnetic component 142 includes a magnetic return system 1424 and the above-mentioned first circuit board 1422. In this embodiment, the magnetic return system 1424 includes a permanent magnet 14241, an iron core 14242 and a washer 14243 to form a magnetic gap 14244, thereby providing a magnetic field to interact with the magnetic field of the diaphragm component 143 to drive the diaphragm component 143 to vibrate.

[0089] In this embodiment, the diaphragm component 143 includes a planar diaphragm 1431, a metal superposition layer 1433 and a voice coil 1434. One end of the voice coil 1434 is connected to the planar diaphragm 1431, and the other end extends into the magnetic return system 1424 and the magnetic gap 14244. The voice coil 1434 is electrically connected to the first circuit board 1422 so that a driving current can be input to generate an electromagnetic field, and interact with the magnetic field of the magnetic return system 1424 so that the voice coil 1434 is driven to reciprocate to drive the planar diaphragm 1431 to vibrate and produce sound.

[0090] In this embodiment of the present invention, similarly, the material of the planar diaphragm 1431 can be a plastic material such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyetherimide (PEI), polyimide (PI), liquid crystal polymer (LCP), polyetheretherketone (PEEK), polycarbonate (PC), polyphenylene sulfide (PPS), or polyarylate (PAR). The metal overlay layer 1433 is made of a metal material such as aluminum. It is attached to the planar diaphragm 1431 but does not receive a driving current. By providing the metal overlay layer 1433 on the flexible planar diaphragm 1431, the planar diaphragm 1431 is tightened, its rigidity is increased, and its elasticity is reduced, thereby increasing the vibration frequency and improving the sound quality.

[0091] The metal overlay 1433 preferably has a hollow or mesh structure. It is planar but has holes or slots. This exposes portions of the planar diaphragm 1431 at locations corresponding to the holes or slots, allowing the planar diaphragm 1431 to pump air. For example, in this embodiment, the metal overlay 1433 includes a plurality of concentric circles 14331, each of which has a pore 14332 formed therein. The metal overlay 1433 is disposed on at least one surface of the planar diaphragm 1431. For example, in this embodiment, two layers of the metal overlay 1433 are disposed on opposite sides of the planar diaphragm 1431. In this case, the voice coil 1434 is bonded to the inner metal overlay 1433 via an adhesive, thereby indirectly connecting to the planar diaphragm 1431.

[0092] Similarly, the diaphragm member 143 also includes at least one counterweight plate 1432, which is disposed at a central position of the metal stack 1433. In other words, the counterweight plate 1432 is surrounded by the metal stack 1433. Furthermore, the counterweight plate 1432 is arranged at the front end surface of the top side of the planar diaphragm 1431, and the voice coil 1434 is located at the rear end surface of the bottom side of the planar diaphragm 1431. The counterweight plate 1432 at the central position of the planar diaphragm 1431 reduces the vibration frequency of the central area of ​​the diaphragm member 143, thereby providing enhanced low-frequency sound effects.

[0093] Preferably, the counterweight plate 1432 is annular and has a central hole 14322. When the counterweight plate 1432 is positioned on the front face of the planar diaphragm 1431, the central hole 14322 exposes the planar diaphragm 1431 to the outside. In other words, the planar diaphragm 1431, at a position corresponding to the central hole 14322, is adapted to pump air through the central hole 14322 and generate vibrations.

[0094] More notably, the sound quality is enhanced by providing the counterweight plate 1432 on the planar diaphragm 1431. In this embodiment, the counterweight plate 1432 is constructed of a metal that is not magnetically attracted, such as copper or stainless steel, to avoid interference with the magnetic field provided by the magnetic return system 1424. When the planar diaphragm 1431 vibrates, its vibration is transmitted to the counterweight plate 1432. Due to the material of the counterweight plate 1432, a heavy, metallic bass effect is produced, thereby compensating for the bass and improving the sound quality of the speaker assembly 14.

[0095] By arranging the counterweight plate 1432 in the central area of ​​the planar diaphragm 1431, the amplitude of vibration is reduced, so that a central area 14311 with the counterweight plate 1432 provides low-frequency sound effects; and an outer edge area 14312 of the planar diaphragm 1431 without the counterweight plate 1432 generates micro-vibration to provide mid- and high-frequency sounds.

[0096] Additionally, it will be appreciated that, in this embodiment, the counterweight plate 1432 and the metal overlay 1433 are made of different metal materials, and the counterweight plate 1432 thickens the diaphragm member 143 in the central region 14311. In another variant embodiment, the counterweight plate 1432 and the metal overlay 1433 may also be integrally formed and made of the same metal material, with the central portion being thicker than the peripheral portion, thereby forming the counterweight plate 1432.

[0097] It can be understood that the plastic planar diaphragm 1431 of the diaphragm component 143 of the present invention increases its rigidity by adding the metal superimposed layer 1433, so that the vibration response speed of the diaphragm component 143 is faster and the generated vibration directionality is stronger, thereby having high sound resolution and being able to restore the recorded sound as realistically as possible, producing a high-fidelity sound quality effect that reaches the monitoring level.

[0098] Furthermore, the structure of the diaphragm member 143 can reduce the airflow generated by the diaphragm member 143 during vibration, thereby reducing the impact on the eardrum. Furthermore, when the semi-open earphone 1 is worn, no completely enclosed space is formed between the ear-facing speaker portion 10 and the eardrum, further reducing the impact of airflow on the eardrum. Consequently, the semi-open earphone 1 can prevent hearing damage during near-field listening, thereby protecting the user's hearing.

[0099] In addition, the diaphragm member 143 allows for providing better sound quality even at lower sound pressure, for example, below 84 dB, so that when the diaphragm member 143 is applied to the earphone 9 , it can be suitable for long-term wear and protect the user's hearing.
