[0004] The embodiment of the present application provides an earphone that can improve the call quality of the earphone and improve the voice recognition capability.

[0005] An embodiment of the present application provides an earphone, comprising a shell, a sound pickup assembly and a vibration sensor, wherein the shell has a accommodating cavity and a mounting port connected to the accommodating cavity; the sound pickup assembly comprises a shell, a diaphragm and a vibration sensor, the shell is arranged at the mounting port and is connected to the shell, and a mounting groove connected to the accommodating cavity is arranged on the inner side of the shell; the diaphragm is installed at the notch of the mounting groove; the vibration sensor is installed in the accommodating cavity and is connected to the diaphragm; wherein, in a worn state, the outer surface of the shell can contact the ear of the user.

[0006] Based on the earphones of the embodiment of the present application, when worn, the outer surface of the shell contacts the ear of the user.

[0025] The utility model provides an earphone 10. The earphone 10 can be in a wired form or a wireless Bluetooth form, and can be connected to communicate with a mobile phone, a computer, an MP3 player, a wearable audio device, and the like.

[0026] Among them, in terms of wearing style, the earphone 10 can be an in-ear earphone 10, or a semi-open earphone 10. When the earphone 10 is configured as an in-ear earphone 10, it can be a bean-shaped earphone, a rod-shaped earphone, etc., and when the earphone 10 is configured as a semi-open earphone 10, it can be an ear-hook earphone 10.

[0027] See also Figures 1 to 3 The earphone 10 may include a housing 100 and a sound pickup assembly 200. Figure 4 , wherein the housing 100 has a receiving cavity (not shown in the figure), and a mounting opening 140 is provided on the surface of the housing 100 for connecting the outside and the receiving cavity. The sound pickup assembly 200 is installed in the receiving cavity, and a part of the area is exposed from the mounting opening 140, so that the exposed part of the sound pickup assembly 200 contacts the ear of the user, and the sound pickup assembly 200 picks up the bone voiceprint of the user when speaking, and converts the bone voiceprint into an electrical signal and sends it to an electronic device connected to the headset 10 for communication.

[0028] The earphone 10 may also include a driving unit (not shown in the figure), a speaker (not shown in the figure), a battery (not shown in the figure), a microphone (not shown in the figure), a sound outlet 300 and an ear cap (not shown in the figure). The driving unit, the battery and the speaker are all contained in the accommodating cavity, the driving unit is electrically connected to the vibration sensor 230, the speaker and the microphone, and the battery is used to provide power to the driving unit, the speaker, the microphone and the vibration sensor 230. The sound outlet 300 is connected to the housing 100, and the sound outlet 300 has a sound channel. The end of the sound outlet 300 is provided with a sound outlet hole connected to the sound channel, and the sound channel is connected to the accommodating cavity. The speaker can transmit sound to the outside through the sound outlet 300. The ear cap is connected to the sound outlet 300 for contacting the external auditory canal of the user. It can be understood that the ear cap is made of a relatively soft material, such as a silicone material, a rubber material, etc., so as to improve the comfort of entering the ear.

[0029] The sound nozzle 300 and the shell 100 can be an integral structure or a split structure; when the sound nozzle 300 and the shell 100 are an integral structure, the sound nozzle 300 can be but is not limited to being formed on the shell 100 by means such as injection molding or 3D printing; when the sound nozzle 300 and the shell 100 are a split structure, the sound nozzle 300 can be but is not limited to being fixed to the shell 100 by means such as bonding or clamping.

[0030] The specific shape of the earphone 10 is not limited here. For example, the shape of the earphone 10 can be, but not limited to, a bean-shaped structure, a rod-shaped structure, or an ear-hook structure. The shell 100 serves as the outer shell 210 of the earphone 10, that is, the designer can reasonably design the shape of the shell 100 according to actual needs. Of course, the specific material of the shell 100 is not limited here. The designer can make a reasonable choice according to actual needs. For example, the material of the shell 100 can be, but not limited to, plastic or metal.

[0031] It is understandable that when the earphone 10 is configured as an earhook earphone 10 (not shown in the figure), the housing 100 includes a main shell (not shown in the figure) and an earhook (not shown in the figure), the main shell has the above-mentioned accommodating cavity, and the earhook is mainly used to be mounted on the user's ear. The earhook is curved and forms a storage space. In some connection methods between the earhook and the main shell, one end of the earhook is rotatably connected to the main shell so that the earhook can switch between a storage position and a wearing position relative to the main shell. When the earhook is in the storage position, the main shell is located in the storage space. When the earhook is in the wearing position, the main shell is located outside the storage space.

[0032] When the earphone 10 is configured as an earhook earphone 10, the sound pickup assembly 200 is disposed on the earhook. A drive unit and a battery may also be disposed in the earhook, and the battery supplies power to the drive unit and the sound pickup assembly 200. When the earhook earphone 10 is worn, the earhook is hung on the periphery of the ear, and the sound pickup assembly 200 fits the ear, which can effectively pick up the vibration generated when the user speaks, and has the advantages of being easy to carry and wear, and is more beautiful when worn, and does not hinder the user's activities.

[0033] Figure 1 A schematic diagram of the structure of an earphone 10 according to an embodiment of the utility model is shown. This embodiment is illustrated by taking the earphone 10 as an in-ear structure. Among them, the housing 100 may include a first shell 110 and a second shell 120, which are buckled and fixed to form the above-mentioned accommodating cavity. In the wearing state, the first shell 110 is located in the external auditory canal of the user, and at least part of the surface is in contact with the external auditory canal; the second shell 120 includes a connecting portion 121 and a rod portion 122 connected to each other, the connecting portion 121 is installed and connected to the first shell 110, part of the surface of the connecting portion 121 is in contact with the external auditory canal, and part of it extends out of the external auditory canal, and the rod portion 122 is exposed to the user's ear in the wearing state. The user can easily wear and remove the earphone 10 by holding the outer surface of the rod portion 122.

[0034] The specific connection method between the first shell 110 and the second shell 120 is not limited here. For example, the first shell 110 and the second shell 120 can be detachably connected or non-detachably connected; when the first shell 110 and the second shell 120 are detachably connected, the first shell 110 can be, but not limited to, connected to the second shell 120 by one or more of the methods such as screw connection or snap connection; when the first shell 110 and the second shell 120 are non-detachably connected, the first shell 110 can be, but not limited to, connected to the second shell 120 by methods such as gluing or welding.

[0035] See also Figure 1 and Figure 2 In some structural forms, two sound pickup assemblies 200 are provided, and two installation openings 140 are provided at intervals on the housing 100, and one sound pickup assembly 200 is installed at one installation opening 140; wherein, one of the two sound pickup assemblies 200 is used to contact the skin of the user's concha cavity, and the other is used to contact the skin of the user's antitragus. Since the vibration signals at the two positions of the concha cavity and the inner side of the antitragus in the human ear are relatively strong when a person speaks, these two positions will obtain relatively strong vibration signals, so that the signal capture effect of the sound pickup assembly 200 is better.

[0036] In the form where the first shell 110 and the second shell 120 are buckled together to form the housing 100, see Figure 5 and Figure 6 , one mounting opening 140 is arranged on the first shell 110, and the other mounting opening 140 is arranged on the lower side of the connecting portion 121 of the second shell 120. The sound pickup assembly 200 installed at the mounting opening 140 on the first shell 110 contacts the concha cavity, and the sound pickup assembly 200 installed at the bottom of the second shell 120 contacts the antitragus. In this way, the two sound pickup assemblies 200 can be respectively installed on the first shell 110 and the second shell 120, and then the first shell 110 and the second shell 120 are fixedly connected, so that the sound pickup assembly 200 can be fixed in the accommodating cavity. With this arrangement, the earphone 10 of the embodiment of the present application has the advantages of simple installation operation and high production efficiency.

[0037] Of course, in other embodiments, the number of sound pickup components 200 may be one, and the one sound pickup component 200 may be used to pick up vibrations at the user's cavum concha, or to pick up vibration signals at the user's antitragus. Alternatively, the number of sound pickup components 200 may be three, four, etc., that is, in addition to picking up vibration signals at the cavum concha and antitragus, the solution of the present application may also pick up vibrations at other parts of the ear. Alternatively, for each part of the cavum concha or antitragus, the present application may use two sound pickup components 200 to pick up vibration signals, and the present application does not impose any limitation on this.

[0038] See also Figures 7 to 9 The pickup assembly 200 includes a housing 210, a diaphragm 220 and a vibration sensor 230. The housing 210 is connected to the housing 100 and sealed at the mounting opening 140. Figure 3 The housing 210 is provided with a mounting groove 213, and the notch of the mounting groove 213 is connected to the accommodating cavity. The edge of the diaphragm 220 is connected to the housing 210 and covers the notch of the mounting groove 213. The vibration sensor 230 is installed in the accommodating cavity and connected to the diaphragm 220; specifically, the vibration sensor 230 is installed on the side of the diaphragm 220 away from the mounting groove 213 and is located in the area of ​​the notch. Among them, the vibration sensor 230 can be attached to the diaphragm 220 by glue or double-sided tape.

[0039] It is understandable that the vibration sensor 230 may be located in the accommodating cavity or in the mounting groove 213 . Fig. 9As shown in the example, the vibration sensor 230 of the embodiment of the present application is mounted on the diaphragm 220 and is located in the accommodating cavity. With such a configuration, the depth of the mounting groove 213 does not need to be very large to meet the installation requirements of the vibration sensor 230, and ensures that the vibration sensor 230 is not likely to interfere with, for example, the housing 210 when the vibration sensor 230 vibrates together with the diaphragm 220.

[0040] Specifically, the shell 210 and the diaphragm 220 of the embodiment of the present application enclose a Helmholtz resonance cavity, so that during use, the bone voiceprint generated when the user speaks is transmitted to the shell 210, and then transmitted to the Helmholtz resonance cavity through the shell 210. When these sound waves pass through the Helmholtz resonance cavity, they will cause the air in the Helmholtz resonance cavity to vibrate, producing a resonance effect. The vibrating air pressure change will act on the diaphragm 220, causing the diaphragm 220 to produce corresponding vibrations. In this process, the bone voiceprint can be amplified and enhanced by the Helmholtz resonance cavity, thereby increasing the signal strength captured by the vibration sensor 230.

[0041] The diaphragm 220 of the embodiment of the present application is spaced apart from the bottom of the mounting groove 213, so that there is enough free space between the housing 210 and the diaphragm 220, so that the diaphragm 220 can vibrate freely in the free space. With this arrangement, the embodiment of the present application can accurately capture different sound signals and is more sensitive. Of course, in some other implementations, the diaphragm 220 can also partially contact the bottom of the mounting groove 213, which can also roughly achieve the above-mentioned effect, and the present application does not limit this.

[0042] The groove depth of the mounting groove 213 of the embodiment of the present application is greater than or equal to 0.3 mm and less than or equal to 10 mm. In this way, when the groove depth of the mounting groove 213 is greater than or equal to 0.3 mm, the diaphragm 220 can have a sufficient vibration amplitude, so that the signal transmitted to the vibration sensor 230 meets the recognition requirement, and when the groove depth of the mounting groove 213 is less than or equal to 10 mm, the volume of the housing 210 can be relatively small, which is also conducive to the miniaturization design of the earphone 10.

[0043] In some structural forms, the ratio of the surface area of ​​the diaphragm 220 to the groove depth of the mounting groove 213 is 40:1 to 50:1. Specifically, it is the ratio of the surface area of ​​the diaphragm 220 to the groove depth. In this way, the present application can match the groove depth when the size of the diaphragm 220 is relatively reasonable, ensuring that the diaphragm 220 has a better frequency range, making it more sensitive when capturing vibration signals, and reducing the size of the diaphragm 220 to save costs.

[0044] In order to facilitate the fixed connection between the housing 210 and the diaphragm 220, please refer to Fig.10A first sinking groove 214 is further provided on the inner side of the housing 210 . The first sinking groove 214 is arranged around the notch of the mounting groove 213 and is communicated with the notch of the mounting groove 213 . The edge of the diaphragm 220 is installed in the first sinking groove 214 .

[0045] The diaphragm 220 of the present application can be fixed to the groove wall of the first groove 214 by gluing, hot melting, welding, etc. Of course, the diaphragm 220 can also be connected to the shell 210 by connecting parts such as screws. Furthermore, the present application can also set the depth of the first groove 214 to be greater than or equal to the thickness of the diaphragm 220. In this way, after the diaphragm 220 is installed, the diaphragm 220 at least does not protrude from the inner side of the shell 210, which can reduce the risk of the diaphragm 220 being separated by scratches from foreign objects during the assembly process. This improves the firmness of the connection between the diaphragm 220 and the shell 210. In addition, when the depth of the first groove 214 is greater than the thickness of the diaphragm 220, the connection surface area between the diaphragm 220 and the shell 210 is larger, so that even in frequent vibration and impact environments, the diaphragm 220 can be stably maintained in the correct position and is not easy to move or loosen.

[0046] In some connection modes between the diaphragm 220 and the housing 210, when the edge of the diaphragm 220 is sealed and connected to the housing 210, the mounting groove 213 forms a closed space. To avoid the air pressure in the mounting groove 213 being inconsistent with the external air pressure when the pickup assembly 200 is working, affecting the stability of the vibration of the diaphragm 220, thereby affecting the stability and quality of the vibration sensor 230 picking up mechanical vibrations and converting electrical signals. The present application provides the following embodiments that can balance the air pressure inside and outside the mounting groove 213:

[0047] In one structural form, see Figure 7 , the diaphragm 220 is provided with a pressure equalizing hole 241 connecting the accommodating cavity and the mounting groove 213. In this way, during the vibration of the diaphragm 220, the pressure equalizing hole 241 can allow airflow to pass through, so as to balance the air pressure between the mounting groove 213 and the accommodating cavity, that is, to play a role in pressure equalization. The pressure equalizing hole 241 can be a circular hole, an elliptical hole, a square hole, a triangular hole, etc., and those skilled in the art can flexibly adjust it according to specific needs, without limitation. Those skilled in the art can also make appropriate adjustments to the number, position and size of the pressure equalizing hole 241 as needed, and the embodiments of the present application are not limited to this.

[0048] In yet another structural form, see Fig. 9, a pressure equalizing channel 242 connecting the accommodating chamber and the mounting groove 213 is provided on the housing 210. The pressure equalizing channel 242 can be arranged inside the housing 210, one end of the pressure equalizing channel 242 is connected to the mounting groove 213, and the other end is connected to the accommodating chamber. The pressure equalizing channel 242 can also be a groove (not shown in the figure) arranged on the side wall of the mounting groove 213, so that when the edge of the diaphragm 220 is connected to the housing 210, the groove is not sealed. The notch formed by the groove connects the accommodating chamber and the mounting groove 213, and the air pressure between the mounting groove 213 and the accommodating chamber can be balanced. It can be understood that those skilled in the art can also make appropriate adjustments to the number, position and size of the pressure equalizing channel 242 as needed, and the embodiments of the present application are not limited to this.

[0049] It should be noted that the above-mentioned pressure equalizing hole 241 and pressure equalizing channel 242 can be formed by stamping, drilling, injection molding, etc.

[0050] In some connection modes between the diaphragm 220 and the shell 210, the diaphragm 220 does not completely cover the shell 210, that is, there is a partial gap between the diaphragm 220 and the shell 210, and the gap connects the mounting groove 213 and the accommodating cavity, so that the air pressure balance between the mounting groove 213 and the accommodating cavity can be achieved. When the vibration sensor 230 is working, the air pressure in the mounting groove 213 can be exchanged with the air pressure in the accommodating cavity through the gap, so as to balance the air pressure difference between the two, so that the problems caused by the air pressure difference can be avoided, while keeping the connection between the diaphragm 220 and the shell 210 stable and reliable, and compared with processing the pressure equalizing hole 241 on the diaphragm 220 or processing the pressure equalizing channel 242 on the shell 210, the structure is further simplified and the manufacturing complexity is reduced. At the same time, it can also effectively achieve the air pressure balance effect between the mounting groove 213 and the accommodating cavity.

[0051] The diaphragm 220 and the housing 210 are made of metal. Among them, the housing 210 can be made of metal materials such as stainless steel, aluminum, silver, etc., and the diaphragm 220 can be made of metal materials such as aluminum, magnesium, silver, etc. Due to the tight structure of the metal material, the propagation speed of sound waves on the surface or inside of the metal is faster. In contrast, the molecular structure inside the plastic is relatively loose, and the propagation speed of sound waves in the plastic is slower. In addition, metal materials have higher rigidity and strength than plastic materials, and the diaphragm 220 made of metal materials is conducive to producing clearer and more accurate sounds, which is suitable for high-pitched ranges. Since the sound of human speech belongs to the high-pitched range, the diaphragm 220 and the housing 210 are prepared by using metal materials, which can make the embodiment of the present application have a higher voice recognition effect. Further, the present application sets the housing 210 and the diaphragm 220 to metal materials, and sets the housing 100 to plastic materials. In this way, while ensuring the improvement of the recognition effect of voice recognition, the weight of the earphone 10 can also be reduced.

[0052] In order to facilitate the fixed connection between the sound pickup assembly 200 and the housing 100, please refer to Figure 4 , a second sinking groove 150 is provided on the inner side of the housing 100, and the second sinking groove 150 is arranged around the installation opening 140; the housing 210 includes a main body 211 and a fixing part 212, the fixing part 212 is connected to the periphery of the main body 211, the main body 211 covers the installation opening 140 and is used to contact the ear of the user, and the fixing part 212 is installed in the second sinking groove 150. It can be understood that the fixing part 212 can be arranged around the periphery of the main body 211 as a whole; or the fixing part 212 can be arranged as a plurality, and the plurality of fixing parts 212 are connected to the periphery of the main body 211 and arranged at intervals, and the present application is not limited thereto.

[0053] In some structural forms, the height of the shell 210 can be adapted to the thickness of the outer shell 100. In this way, when the shell 210 is embedded in the mounting port 140, the outer surface of the shell 210 smoothly transitions to the outer surface of the outer shell 100, and the side of the diaphragm 220 facing the accommodating cavity is relatively flush with the cavity wall of the accommodating cavity, so that the shell 210 and the diaphragm 220 can be embedded in the outer shell 100, thereby improving the stability of the shell 210 and the diaphragm 220.

[0054] The specific connection method between the shell 100 and the shell 210 is not limited here. For example, the shell 100 and the shell 210 can be detachably connected or non-detachably connected; when the shell 100 and the shell 210 are detachably connected, the fixing portion 212 can be, but is not limited to, fixed to the second sink 150 by one or more methods such as screw connection or snap connection; when the shell 100 and the shell 210 are non-detachably connected, the fixing portion 212 can be, but is not limited to, fixed to the second sink 150 by methods such as gluing or welding.

[0055] In order to improve the user's comfort during wearing, the outer surface of the shell 210 transitions smoothly with the outer surface of the housing 100. The outer surface of the shell 210 and the outer surface of the housing 100 show a consistent curve change trend, forming a continuous surface with a smooth transition. Moreover, there is no step difference between the outer edge of the shell 210 and the inner edge of the mounting port 140, that is, the height between the shell 210 and the housing 100 is almost flush. In this way, the outer surface of the earphone 10 can not only fit the user's external auditory canal more closely, but also avoid protrusions or depressions on the surface of the earphone 10. During wearing, the user does not have relatively convex areas squeezing the ears, or relatively concave areas poking the ears, thereby bringing a more comfortable wearing experience. In addition, the embodiment of the present application can also be made more beautiful as a whole.

[0056] Of course, in some other embodiments, a portion of the outer surface of the shell 210 may be protruding relative to the outer surface of the housing 100, so as to improve the stability of the contact between the pickup assembly 200 and the user's ear canal, and the present application does not impose any restrictions on this.

[0057] The earphone 10 according to the embodiment of the present application responds to external vibrations through the housing 210 and the diaphragm 220. Specifically, in the wearing state, the outer surface of the housing 210 contacts the ear of the user. When the human body speaks, the bone soundprint vibration signal of the ear will be transmitted to the housing 210, and then transmitted to the diaphragm 220 through the housing 210. The resonance effect between the diaphragm 220 and the housing 210 enhances the bone soundprint vibration signal, thereby improving the signal strength captured by the vibration sensor 230. The vibration sensor 230 converts the captured vibration signal into an electrical signal and transmits it to the drive unit, which then transmits it to an external electronic device through a cable or a wireless communication device. The external electronic device can be a mobile phone, a tablet, a computer, etc. In this way, compared with the related art that only picks up the sound signal of human speech through air conduction, the earphone 10 in which the pickup assembly 200 and the vibration sensor 230 are added in the embodiment of the present application can reduce the influence of external noise, improve the voice recognition ability, and can also bring better call effects and improve call quality in a noisy environment.

[0058] In summary, the design of the earphone 10 based on the housing 210 and the diaphragm 220 can not only effectively receive the bone voiceprint vibration signal of the human body, but also improve the signal strength through the resonance effect. This technology is particularly effective in an environment with large noise interference, and can provide a better call experience and voice recognition performance.
