[0025] Please refer to Figure 1 The earphone system 10000 provided by the embodiments of the present application includes an earphone 1000 and a charging box 3000. The charging box 3000 is used to charge the earphone 1000. Among them, since the earphone system 10000 in the present embodiment includes the earphone 1000, it can be understood that the earphone system 10000 at least includes the same beneficial effects as the earphone 1000, therefore, the beneficial effects of the earphone system 10000 please refer to the beneficial effects of the earphone 1000 introduced below.

[0026] In some embodiments of the present application, the earphone 1000 can be worn on the ear of a user and can be used in cooperation with a mobile phone, a computer, a smart wearable device (such as a smart watch, a smart bracelet, smart glasses, a smart helmet, etc.), a head-mounted device, a virtual reality device, and the like.

[0027] Specifically, in some embodiments, the earphone 1000 includes an air conduction earphone and a bone conduction earphone. The air conduction earphone is a kind of earphone that transmits sound through air vibration. The bone conduction earphone is a kind of earphone that converts sound into different mechanical vibrations and transmits sound waves through the human skull, bone labyrinth, inner ear lymph, cochlea, auditory center, and the like.

[0028] It should be noted that the ear of the user includes the external auditory canal, the concha cavity, the cymba concha, the triangular fossa, the helix, the antihelix, and the like. The concha cavity, the cymba concha, the triangular fossa, and the like have a certain depth and volume in the three-dimensional space. The external auditory canal is a curved duct that extends medially from the external auditory meatus at the depth of the concha cavity to the tympanic membrane.

[0029] Further, in some embodiments, the earphone 1000 includes a transduction assembly 100, which is a structure in the earphone 1000 for enabling the user to hear sound. In one example, in the case where the earphone 1000 is a bone conduction earphone, the transduction assembly 100 is configured to be located on the front side of the ear when the earphone 1000 is in a wearing state, at which time the transduction assembly 100 does not block the external auditory canal. In another example, in the case where the earphone 1000 is an air conduction earphone, the transduction assembly 100 is configured to at least partially extend into at least one of the concha cavity, the cymba concha, the triangular fossa, and the like when the earphone 1000 is in a wearing state.

[0030] Please refer to Figure 2 The transduction assembly 100 provided by the embodiments of the present application includes a housing 10, an active vibration assembly 30, and a passive vibration assembly 50. The housing 10 includes a contact region 101 that contacts the ear and a non-contact region 103 that does not contact the ear, and is provided with a receiving cavity 105. The contact region 101 is provided with a sound outlet hole 111, and the non-contact region 103 is provided with a mounting hole 151. The active vibration assembly 30 is received in the receiving cavity 105 and is used to vibrate to generate a first sound wave. At least part of the first sound wave is output from the sound outlet hole 111. Part of the first sound wave output from the sound outlet hole 111 is transmitted to the inner ear through the external auditory canal, and the other part is transmitted to the environment. The passive vibration assembly 50 is mounted in the mounting hole 151. The passive vibration assembly 50 vibrates to generate a second sound wave under the action of the vibration of the active vibration assembly 30. The second sound wave is used to cancel the first sound wave in the environment.

[0031] Specifically, the shell 10 is a structure for mounting other elements and housing the other elements inside the shell 10. The shell 10 of the present application is at least used for mounting the active vibration assembly 30 and housing the active vibration assembly 30 inside the shell 10 to protect the active vibration assembly 30. The cross-sectional shape of the shell 10 can be, but is not limited to, a circle, an ellipse, a rectangle, or other polygons, etc. The cross-sectional shape of the shell 10 of the present application is approximately a racetrack shape. The material of the shell 10 can be plastic or metal, etc. In the case that the material of the shell 10 is plastic, the shell 10 has good insulation performance, low cost, and light weight. In the case that the material of the shell 10 is metal, the shell 10 has high strength, good wear resistance, and long service life.

[0032] The shell 10 includes a contact area 101 in contact with the ear and a non-contact area 103 not in contact with the ear. The contact area 101 is an area where the shell 10 is in contact with the concha, the antihelix, etc. of the auricle to achieve stable wearing when the user wears the earphone 1000. The non-contact area 103 is an area not directly in contact with the auricle. The non-contact area 103 and the contact area 101 together enclose a receiving cavity 105 to provide mounting space for other components in the earphone 1000. The contact area 101 is provided with a sound hole 111 for transmitting the first sound wave generated by the active vibration assembly 30 from the inside of the shell 10 to the outside of the shell 10. The non-contact area 103 is provided with a mounting hole 151 for mounting the passive vibration assembly 50. The sound hole 111 and the mounting hole 151 can be one or multiple, which is not limited in the present application. The sound hole 111 and the mounting hole 151 can be, but are not limited to, a circle, an ellipse, a triangle, a quadrilateral, or other polygons, etc.

[0033] The active vibration assembly 30 is used to generate the first sound wave. Exemplarily, the active vibration assembly 30 is a loudspeaker. The active vibration can drive the diaphragm inside the active vibration assembly 30 to vibrate, thereby pushing the surrounding air to form the first sound wave. The first sound wave is transmitted from the sound hole 111 of the shell 10. Part of the first sound wave output from the sound hole 111 is transmitted to the inner ear through the external auditory canal, and the other part is transmitted to the environment. It can be understood that, ideally, the earphone 1000 should transmit as little first sound wave to the environment as possible to avoid sound leakage of the earphone 1000.

[0034] The passive vibration component 50, also known as a passive cone or a passive radiator, is a component capable of generating vibrations under the action of external force. The passive vibration component 50 is installed in the mounting hole 151, and further, a part of the passive vibration component 50 is located inside the shell 10 and a part is located outside the shell 10. The passive vibration component 50 can generate a second sound wave by vibration under the action of the first sound wave generated by the active vibration component 30. The second sound wave can be transmitted to the environment, and the first sound wave and the second sound wave have certain differences in vibration direction, frequency, and phase difference, etc. The first sound wave and the second sound wave can produce destructive interference, thereby weakening the sound wave intensity, thereby reducing the first sound wave leaked in the environment.

[0035] In the transduction assembly 100 of the present application, in a first aspect, a part of the first sound wave can be transmitted from the sound outlet hole 111 to the ear, and another part of the first sound wave can drive the passive vibration component 50 to vibrate. The passive vibration component 50 can improve the low-frequency energy of the first sound wave, form a second sound wave with stronger bass effect, and improve the hearing effect; in a second aspect, the second sound wave can interfere with the leakage sound of the first sound wave from the ear, and the interference can be mutually offset to reduce the leakage sound, thereby further improving the hearing effect; in a third aspect, the passive vibration component 50 is installed in the mounting hole 151, and can block the mounting hole 151, thereby improving the waterproof effect of the transduction assembly 100.

[0036] Please refer to Figure 2 In some embodiments, the shell 10 includes opposite bottom wall 11 and top wall 13, and side wall 15 surrounding the bottom wall 11 and the top wall 13. The bottom wall 11, the top wall 13 and the side wall 15 together form a receiving cavity 105, the bottom wall 11 is the contact area 101, and the top wall 13 and / or the side wall 15 is the non-contact area 103.

[0037] Specifically, in some embodiments, the bottom wall 11 and the side wall 15 are an integral structure, i.e., the bottom wall 11 and the side wall 15 are one whole structure, thereby being able to improve the bonding strength between the bottom wall 11 and the side wall 15, preventing the bottom wall 11 and the side wall 15 from being separated during the operation of the shell 10, and thus ensuring the stability and reliability of the operation of the shell 10. In other embodiments, the bottom wall 11 and the side wall 15 are a split structure, i.e., the bottom wall 11 and the side wall 15 are two different structures. In one example, the bottom wall 11 and the side wall 15 can be combined together by a detachable connection mode, which includes but is not limited to a buckle connection or a threaded connection, etc. In another example, the bottom wall 11 and the side wall 15 can be combined together by a non-detachable connection mode, which includes but is not limited to bonding or welding, etc. Further, the top wall 13 and the bottom wall 11 can also be an integral or split structure, which is not described here. In one implementation, the top wall 13 is the non-contact area 103, in another implementation, the side wall 15 is the non-contact area 103, and in still another implementation, the top wall 13 and the side wall 15 are both the non-contact area 103.

[0038] The bottom wall 11, the top wall 13 and the side wall 15 jointly form the accommodating cavity 105. The accommodating cavity 105 can converge the first sound wave, so that the first sound wave generated by the active vibration assembly 30 is more concentrated in the direction of the sound outlet hole 111, reducing the possible loss or deviation of the first sound wave during propagation. When the first sound wave is output through the sound outlet hole 111, the converging effect of the accommodating cavity 105 can help the first sound wave to be concentrated in the direction of the external ear canal, thereby increasing the proportion of the first sound wave entering the external ear canal, improving the transmission efficiency of the first sound wave, reducing the first sound wave leaking to the environment, and helping to reduce the sound leakage.

[0039] Please refer to Figure 2 In some embodiments, the mounting hole 151 includes a first mounting hole 1511 and a second mounting hole 1512, and the passive vibration assembly 50 includes a first passive vibration member 51 and a second passive vibration member 52, the first passive vibration member 51 is installed in the first mounting hole 1511, and the second passive vibration member 52 is installed in the second mounting hole 1512.

[0040] Specifically, the first mounting hole 1511 and the second mounting hole 1512 can have the same or different cross-sectional shapes. For example, the first mounting hole 1511 can have a circular cross-sectional shape, and the second mounting hole 1512 can have a runway shape. The first mounting hole 1511 and the second mounting hole 1512 can have the same or different cross-sectional areas. In this application, the first mounting hole 1511 and the second mounting hole 1512 both have a runway shape, which is more conducive to forming. The interference efficiency of the two passive vibration pieces is higher, which can expand the propagation range of the second sound wave, thereby expanding the interference range of the first sound wave and reducing the leakage of sound. Further, the first passive vibration piece 51 and the second passive vibration piece 52 are respectively mounted in different mounting holes 151, i.e., the first passive vibration piece 51 is mounted in the first mounting hole 1511, and the second passive vibration piece 52 is mounted in the second mounting hole 1512. Therefore, the first passive vibration piece 51 and the second passive vibration piece 52 can form the second sound wave from two positions, and the second sound wave generated by the first passive vibration piece 51 and the second passive vibration piece 52 comes from different positions. Therefore, the frequency and phase difference of the two groups of second sound waves have certain differences, which are more likely to interfere with the first sound wave.

[0041] In addition, the two passive vibration pieces also provide a redundant design. In the event of a malfunction or performance degradation of one of the passive vibration pieces, the other passive vibration piece can still vibrate to generate a second sound wave under the action of the first sound wave, thereby interfering with the first sound wave in the environment and maintaining the influence on the first sound wave in the environment.

[0042] Please refer to Figure 2 In some embodiments, the first passive vibration piece 51 and the second passive vibration piece 52 are arranged on the side wall 15, and in a direction perpendicular to the thickness direction Z of the transduction assembly 100, the first passive vibration piece 51 and the second passive vibration piece 52 are arranged opposite to each other.

[0043] Specifically, the direction perpendicular to the thickness direction Z of the transduction assembly 100 is the width direction X. It can be understood that the side wall 15 surrounds the bottom wall 11 with the sound hole 111, and in the case that the user wears the earphone 1000, the first passive vibration piece 51 and the second passive vibration piece 52 are arranged opposite to each other in the width direction X, so as to be distributed on opposite sides of the concha cavity in a direction perpendicular to the cross section of the human body. After the first sound wave is output from the sound hole 111, part of it enters the ear canal through the concha cavity, and part of it spreads to the environment from the periphery of the concha cavity. Therefore, in the case that the user wears the earphone 1000, the first passive vibration piece 51 and the second passive vibration piece 52 can interfere with the first sound wave leaked into the environment on opposite sides of the concha cavity, thereby reducing the leakage of sound.

[0044] Secondly, the relative arrangement of the first passive vibration member 51 and the second passive vibration member 52 balances the spatial distribution of the first passive vibration member 51 and the second passive vibration member 52, and the vibration forces of the two passive vibration members arranged oppositely will offset each other to some extent, balancing the force generated by the passive vibration assembly 50 when vibrating on the shell 10, thereby reducing the stress concentration or deformation problem of the shell 10 due to vibration, and improving the service life of the earphone 1000.

[0045] Referring to Figure 2 In some embodiments, in the width direction X of the transduction assembly 100, the distance between the first passive vibration member 51 and the sound hole 111 is greater than the distance between the second passive vibration member 52 and the sound hole 111.

[0046] Specifically, the distance between the first passive vibration member 51 and the sound hole 111 is greater than the distance between the second passive vibration member 52 and the sound hole 111, and because the propagation paths of sound waves are different, the sound waves generated by the first passive vibration member 51 and the second passive vibration member 52 will experience different time delays during propagation, forming a phase difference, and more easily forming a complementary relationship in frequency and phase with the leaked first sound wave, thereby more effectively forming interference with the first sound wave.

[0047] Referring to Figure 2 In some embodiments, the volume of the first passive vibration member 51 is greater than the volume of the second passive vibration member 52.

[0048] Specifically, the second passive vibration member 52 close to the sound hole 111 has a small volume, which helps to avoid unnecessary attenuation caused by interference between the second passive vibration member 52 and the first sound wave, thereby reducing its interference with the first sound wave entering the external auditory canal. Ensure that the first sound wave can be transmitted more clearly to the external auditory canal.

[0049] And the first passive vibration member 51 away from the sound hole 111 has a large volume, which can provide sufficient energy for generating the second sound wave, and ensure that the second sound wave can effectively interfere with the first sound wave, thereby reducing the leakage of sound.

[0050] Referring to Figure 2 In some embodiments, the passive vibration assembly 50 is made of silica gel.

[0051] Specifically, silica gel has good elasticity and flexibility, so the passive vibration assembly 50 made of silica gel can quickly respond under the influence of the first sound wave and vibrate to generate the second sound wave, thereby improving the sensitivity and accuracy of the passive vibration assembly 50 in generating the second sound wave. Secondly, silica gel has excellent durability and anti-aging performance, and can maintain stable mechanical and acoustic properties in long-term use. At the same time, silica gel has good temperature resistance and can work normally under different temperature environments, with strong adaptability.

[0052] Further, since the silica gel has a certain elasticity, the passive vibration assembly 50 arranged in the mounting hole 151 also has a sealing function for sealing the mounting hole 151. When the passive vibration assembly 50 is mounted in the mounting hole 151, it is in close contact with the side wall 15 of the mounting hole 151, thereby sealing the gap between the passive vibration assembly 50 and the side wall 15 of the mounting hole 151. On the one hand, it can prevent the first sound wave from leaking out of the gap, and on the other hand, it can prevent fluid from flowing into the inside of the shell 10 from the gap, thereby improving the waterproof level of the earphone 1000 and prolonging the service life of the earphone 1000.

[0053] Referring to Figure 2 In some embodiments, the passive vibration assembly 50 is made of polyethylene.

[0054] Specifically, polyethylene has excellent durability, impact resistance, and better elasticity, and can maintain stable performance during long-term use, especially in a vibrating environment, and has strong impact resistance. Therefore, when the passive vibration assembly 50 made of polyethylene receives the vibration of the active vibration assembly 30, it can vibrate in response and form a second sound wave. In addition, polyethylene has a low density, which helps to reduce the overall weight of the earphone 1000, improve wearing comfort, avoid discomfort caused by excessive weight, and reduce pressure on the ear. Polyethylene also has a low cost, which makes it an ideal material with high cost performance, allowing it to maintain a high performance level while reducing production costs. Finally, the chemical stability and corrosion resistance of polyethylene enable it to work stably in various environments and are not easily oxidized or corroded, thereby prolonging the service life of the passive vibration assembly 50.

[0055] Referring to Figure 2 In some embodiments, the active vibration assembly 30 vibrates in the thickness direction Z of the transduction assembly 100, and the sound outlet hole 111 is opposite to the active vibration assembly 30 in the thickness direction Z of the transduction assembly 100.

[0056] Specifically, the sound outlet hole 111 is located in the vibration direction of the active vibration assembly 30, which can ensure that the sound wave generated by the active vibration assembly 30 is directly transmitted through the sound outlet hole 111, shortening the propagation path of the first sound wave, so that the first sound wave can be more directly and clearly transmitted to the user's ear canal. Since the vibration direction of the active vibration assembly 30 is aligned with the sound outlet hole 111, the first sound wave can be more efficiently transmitted from the vibrating component to the sound outlet hole 111, reducing possible attenuation or distortion in the sound wave transmission process, improving the transmission efficiency of the sound wave, and ensuring that the propagation direction of the sound matches the ear canal, thereby improving the sound quality of the earphone 1000 and the auditory experience of the user.

[0057] Referring to Figure 2In some embodiments, the active vibration component 30 comprises a support member, a spring, and a vibration member, at least a portion of the support member is connected with the housing 10, the vibration member is installed on the support member, the spring is connected with the vibration member, and the vibration member is capable of vibrating at least partially, and the vibration member is capable of driving the spring to vibrate.

[0058] Specifically, at least a portion of the support member is connected with the housing 10 to provide support for the active vibration component 30, and to ensure that the active vibration component 30 can maintain a relatively stable position during vibration, thereby avoiding unnecessary vibration or noise. The active vibration component 30 is installed on the support member and is used to generate the first sound wave. When an electric signal acts on the active vibration component 30, the main part can vibrate, thereby generating the first sound wave through vibration. The spring is connected with the active vibration component 30 and can convert the vibration of the active vibration component 30 into a larger range of vibration, enhancing the propagation effect of the first sound wave. The elastic properties of the spring help maintain the continuity of the vibration process, making the propagation of the first sound wave more stable. More specifically, the active vibration component 30 (loudspeaker) generates the first sound wave through the combined action of the support member, the spring, and the vibration member. First, the electric signal is transmitted to the vibration member through the wire, and the active vibration component 30 usually comprises an electromagnetic coil and a vibration diaphragm connected therewith. When the electric signal passes through the electromagnetic coil, a magnetic force is generated in the magnetic field, thereby causing the active vibration component 30 to vibrate. Since the active vibration component 30 is connected with the spring, the movement of the active vibration component 30 will drive the spring to vibrate. The vibration frequency and amplitude of the active vibration component 30 are determined by the frequency and strength of the electric signal. When the active vibration component 30 starts to vibrate, the air is also vibrated by the active vibration component 30, and the air vibration is propagated to the surrounding environment in the form of a sound wave.
