[0002] Headphones typically have a sound pickup channel on their shell, and a microphone is placed inside the shell at the corresponding position of the sound pickup channel to enable call functionality. However, headphone shells are prone to compression deformation during manufacturing, which can lead to poor alignment accuracy of the microphone relative to the sound pickup channel after assembly. This can negatively impact the acoustic performance of the microphone and reduce the overall performance of the headphones. Summary of the Invention

[0003] The purpose of this application is to provide an earphone to solve the technical problem in the prior art where the alignment accuracy of the assembled microphone relative to the pickup channel deteriorates.

[0005] A microphone for making calls, wherein the microphone has a microphone hole for receiving calls;

[0006] The housing has a call receiving cavity with an open mouth structure for accommodating the call microphone. The bottom of the call receiving cavity is used to position the call microphone. The housing has a pickup channel on the side wall of the call receiving cavity that communicates with the outside. When the call microphone is accommodated in the call receiving cavity, the pickup channel is aligned with and communicates with the call receiving hole. The housing also has a pre-deformation groove on the bottom of the call receiving cavity.

[0007] In one embodiment, the groove wall on the side of the pre-deformed groove closest to the pickup channel is an arc surface, and the groove wall on the side of the pre-deformed groove away from the pickup channel is a plane.

[0008] In one embodiment, the groove width on the opening side of the pre-deformed groove is greater than the groove width on the bottom side.

[0009] In one embodiment, the housing also has a deformation notch on the groove wall of the pre-deformation groove near the pickup channel.

[0010] In one embodiment, the housing has a first pickup hole on the side wall of the call receiving cavity, and a second pickup hole communicating with the outside is formed at the bottom of the first pickup hole. The first pickup hole and the second pickup hole together form the pickup channel, and the cross-sectional dimension of the second pickup hole is larger than that of the first pickup hole.

[0011] In one embodiment, the earphone further includes a call tuning component housed within the call receiving cavity and disposed on the side of the call microphone facing the pickup channel. The call tuning component has a call tuning hole that connects the pickup channel and the call receiving hole. The radial dimension of the call tuning hole is larger than the radial dimension of the call receiving hole and larger than the cross-sectional dimension of the pickup channel.

[0012] In one embodiment, the housing has a noise-reducing receiving hole on its inner side, and a sound receiving channel communicating with the outside is formed at the bottom of the noise-reducing receiving hole. The noise-reducing receiving hole and the call receiving cavity are located opposite each other on both sides of the housing. The earphone further includes:

[0013] A noise-canceling microphone is disposed within the noise-canceling receiving hole and is used to achieve noise reduction;

[0014] A sealing cover is fitted over the outside of the noise-canceling microphone and is used to seal the noise-canceling microphone and the noise-canceling receiving hole. The sealing cover has a sealing receiving port on its side facing the receiving channel, which is aligned with and passes through the receiving channel.

[0015] The noise-reducing microphone has multiple noise-reducing holes on the side facing the sealed microphone and in the corresponding area of ​​the sealed microphone.

[0016] In one embodiment, the housing has a first sound-receiving hole at the bottom of the noise-reducing receiving hole, and a second sound-receiving hole communicating with the outside is formed at the bottom of the first sound-receiving hole.

[0017] In one embodiment, the earphone further includes a noise-canceling tuning component housed within the noise-canceling receiving hole and disposed between the sealing cover and the bottom of the noise-canceling receiving hole. The noise-canceling tuning component has a noise-canceling tuning hole that connects the sealed microphone port and the pickup channel. The radial dimension of the noise-canceling tuning hole is smaller than the cross-sectional dimension of the sealed microphone port and larger than the cross-sectional dimension of the pickup channel.

[0018] In one embodiment, the earphones further include a touch screen connected to the housing and for use by a user, the touch screen including a protective portion connected to the housing and a touch portion recessed relative to the protective portion.

[0019] The beneficial effects provided by this application are as follows:

[0020] The earphone provided in this application embodiment has a call receiving cavity designed inside the shell to accommodate the call microphone. A pre-deformation groove is also provided at the bottom of the call receiving cavity. Based on the setting of the pre-deformation groove, when the shell is formed and there is compression deformation, the deformation of the shell on the bottom side of the call receiving cavity and the shell on the periphery of the pre-deformation groove is concentrated in the pre-deformation groove. Based on this, the offset of the bottom of the call receiving cavity towards the cavity opening can be effectively reduced, thereby ensuring the positioning effectiveness of the bottom of the call receiving cavity for the call microphone. It can also ensure that when the call microphone is accommodated in the call receiving cavity, its call reception hole can be accurately aligned with the pickup channel. That is, it effectively improves the alignment accuracy of the call microphone relative to the pickup channel, so that external sound can be accurately transmitted to the call microphone through the pickup channel and received by the call microphone, improving the sound collection effect of the call microphone and, to a certain extent, ensuring and improving the acoustic performance of the earphone.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] The specific implementation of this application will be described in more detail below with reference to specific embodiments:

[0036] Please see Figure 1 , Figure 2 , Figure 3 This application provides an earphone, which includes a microphone 100 and a housing 200.

[0037] The microphone 100 is used to make calls and has a microphone hole 101. The housing 200 has a microphone cavity 201 with an open mouth structure for accommodating the microphone 100. The bottom of the microphone cavity 201 is used to position the microphone 100. The housing 200 has a pickup channel 202 on the side wall of the microphone cavity 201 that connects to the outside. When the microphone 100 is accommodated in the microphone cavity 201, the pickup channel 202 is aligned with and connected to the microphone hole 101. The housing 200 also has a pre-deformation groove 203 on the bottom of the microphone cavity 201.

[0038] It should be noted that the microphone 100 can be inserted into the call receiving cavity 201 through its opening. When the microphone 100 is housed in the call receiving cavity 201 and supported and positioned by the bottom of the cavity, it is aligned with the pickup channel 202. When a mobile device connected to the headset (or Bluetooth) enters a call state, the microphone 100 can clearly capture the user's voice from the outside through the pickup channel 202 to enable communication.

[0039] It should also be noted that, while retaining part of the bottom of the call receiving cavity 201 to support and position the call microphone 100, the housing 200 also has a pre-deformation groove 203 pre-designed on the bottom side of the bottom of the call receiving cavity 201. The pre-deformation groove 203 and the call receiving cavity 201 are formed together when the housing 200 is formed. Optionally, the housing 200 with the pre-deformation groove 203 and the call receiving cavity 201 can be formed by injection molding.

[0040] Based on the setting of the pre-deformation groove 203, when the housing 200 is formed and there is compression deformation, the deformation of the housing 200 on the bottom side of the pre-deformation groove 203 and the cavity 201 (the part compressed towards the cavity opening) can be concentrated at the pre-deformation groove 203. At this time, the pre-deformation groove 203 will be compressed, but it can avoid the deformed part from crowding towards the cavity opening due to lack of deformation space. This can reduce the displacement of the cavity bottom of the cavity 201 towards the cavity opening to a certain extent, so that even if the cavity bottom of the cavity 201 has a slight displacement, its actual position can be close to the original design position. This can ensure the positioning effect of the cavity bottom of the cavity 201 on the microphone 100, so that when the microphone 100 is accommodated in the cavity 201, its microphone hole 101 can be accurately aligned with the pickup channel 202 in the cavity opening direction.

[0041] In addition, the housing 200 may also have compressive deformation on its cross section. The inner walls of the call receiving cavity 201 and the pre-deformation groove 203 may be compressed inward. At this time, the deformation of the periphery of the pre-deformation groove 203 will not crowd towards the cavity opening due to the setting of the pre-deformation groove 203, thereby further reducing the displacement of the cavity bottom of the call receiving cavity 201 towards the cavity opening, so as to further ensure and improve the alignment accuracy of the call receiving hole 101 and the pickup channel 202.

[0042] Optionally, while ensuring that the microphone 100 can be placed upright without tilting when housed in the microphone cavity 201, the cross-sectional size of the microphone cavity 201 can be set to be slightly larger than the size of the microphone 100. With this setting, even if the housing 200 undergoes compression deformation in its cross-section, it will not cause the microphone 100 to be difficult to insert into the microphone cavity 201, which can reduce the assembly difficulty of the microphone 100 to a certain extent.

[0043] In summary, the earphone provided in this application embodiment has a call receiving cavity 201 within the housing 200 capable of accommodating the microphone 100. A pre-deformation groove 203 is also provided at the bottom of the call receiving cavity 201. Based on the pre-deformation groove 203, when the housing 200 is formed and undergoes compression deformation, the deformation of the housing 200 on the bottom side of the call receiving cavity 201 and the pre-deformation groove 203, as well as the deformation of the housing 200 on the periphery of the pre-deformation groove 203, can be concentrated in the pre-deformation groove 203. Therefore, the deformation of the bottom of the call receiving cavity 201 towards the cavity opening can be effectively reduced. The offset ensures the effective positioning of the bottom of the call cavity 201 relative to the microphone 100. It also ensures that when the microphone 100 is housed in the call cavity 201, its call reception hole 101 can be accurately aligned with the pickup channel 202. This effectively improves the alignment accuracy of the microphone 100 relative to the pickup channel 202, allowing external sounds to be accurately transmitted to and received by the microphone 100 via the pickup channel 202. This improves the sound acquisition effect of the microphone 100 and, to a certain extent, guarantees and enhances the acoustic performance of the headphones.

[0044] Please see Figure 2 , Figure 3 , Figure 6 In this embodiment, the wall of the pre-deformation groove 203 near the pickup channel 202 is curved, while the wall of the pre-deformation groove 203 away from the pickup channel 202 is flat. By adopting the above scheme, the cross-sectional dimensions of the pre-deformation groove 203 can be regularly varied based on the curved groove wall, thereby transitioning and guiding the deformation amplitude of the periphery and bottom of the pre-deformation groove 203. Based on this, the risk of the bottom of the call receiving cavity 201 shifting towards the cavity opening can be further reduced, which is conducive to further ensuring and improving the alignment accuracy between the call receiving hole 101 and the pickup channel 202.

[0045] Optionally, the groove wall of the pre-deformation groove 203 near the pickup channel 202 is equidistant from the outer surface of the housing 200. By adopting the above scheme, the distances between each point on the groove wall of the pre-deformation groove 203 near the pickup channel 202 and the outer surface of the housing 200 are equal. Based on this, the deformation of the housing 200 around the pre-deformation groove 203 can be balanced. On the one hand, this can further reduce the risk of the bottom of the call receiving cavity 201 shifting towards the cavity opening due to the housing 200 around the pre-deformation groove 203 crowding towards the cavity opening, thereby further ensuring and improving the alignment accuracy between the call receiving hole 101 and the pickup channel 202. On the other hand, it also helps to ensure the shape of the housing 200, avoiding the impact of uneven deformation of the housing 200 on the wearing effect of the headphones, thereby ensuring and improving the performance of the headphones.

[0046] Please see Figure 2 , Figure 3 , Figure 6 In this embodiment, the width of the pre-deformed groove 203 at its opening is greater than the width at its bottom. By adopting the above scheme, the cross-sectional shape of the pre-deformed groove 203 can be funnel-shaped. Based on this, on the one hand, it is conducive to demolding, thereby reducing the molding difficulty of the pre-deformed groove 203. On the other hand, the cross-sectional area of ​​the pre-deformed groove 203 can gradually increase from its bottom side to its opening side. In this way, a larger deformable space can be reserved closer to the bottom of the communication cavity 201, thereby further reducing the risk of the bottom of the communication cavity 201 shifting towards the opening side, which is conducive to further ensuring and improving the alignment accuracy between the communication receiver hole 101 and the pickup channel 202.

[0047] Please see Figure 2 , Figure 3 , Figure 6 In this embodiment, the housing 200 also has a deformation notch 204 on the groove wall of the pre-deformation groove 203 near the pickup channel 202. By adopting the above solution, on the one hand, the transmission of contraction stress on both sides of the deformation notch 204 can be cut off by the deformation notch 204, thereby effectively reducing the influence of the deformation on the top side of the deformation notch 204, and further reducing the risk of the bottom of the communication receiving cavity 201 shifting towards the cavity opening side, which is conducive to further ensuring and improving the alignment accuracy of the communication receiving hole 101 and the pickup channel 202; on the other hand, the cross-sectional area at the deformation notch 204 can be enlarged, thereby effectively slowing down the speed at which the deformation on the bottom side of the deformation notch 204 radiates towards the groove opening side, thereby further reducing the influence of the deformation on the top side of the deformation notch 204, and further reducing the risk of the bottom of the communication receiving cavity 201 shifting towards the cavity opening side, which is conducive to further ensuring and improving the alignment accuracy of the communication receiving hole 101 and the pickup channel 202.

[0048] Please see Figure 2 , Figure 3 , Figure 5 In this embodiment, the central axis of the pickup channel 202 coincides with the central axis of the call microphone 101. By adopting the above scheme, the coaxiality of the pickup channel 202 and the call microphone 101 can be improved, that is, the alignment accuracy of the pickup channel 202 and the call microphone 101 can be improved. This facilitates reliable transmission of sound from the pickup channel 202 to the call microphone 101, thereby further improving the sound acquisition effect of the call microphone 100 and further improving the acoustic performance of the headphones.

[0049] Please see Figure 2 , Figure 3 , Figure 5 In this embodiment, the housing 200 has a first pickup hole 2021 on the side wall of the communication receiving cavity 201, and a second pickup hole 2022 communicating with the outside is formed at the bottom of the first pickup hole 2021. The first pickup hole 2021 and the second pickup hole 2022 together form a pickup channel 202, and the cross-sectional dimension of the second pickup hole 2022 is larger than that of the first pickup hole 2021. It should be noted that the external sound is first transmitted to the first pickup hole 2021 through the second pickup hole 2022, and then transmitted to the communication receiving hole 101 of the communication microphone 100 through the first pickup hole 2021. By setting the cross-sectional size of the second pickup hole 2022 to be larger than that of the first pickup hole 2021, sound can be received diffusely first through the larger second pickup hole 2022, thus expanding the sound reception range of the second pickup hole 2022. Then, sound is transmitted centrally through the first pickup hole 2021, thus concentrating the sound transmitted by the first pickup hole 2021 and improving the clarity of the sound captured by the microphone 100. Therefore, by adopting the above solution, the sound acquisition effect of the microphone 100 can be further improved, and the acoustic performance of the headphones can be further enhanced.

[0050] Please see Figure 2 , Figure 3 , Figure 5In this embodiment, the earphone also includes a call tuning component 300 housed within the call receiving cavity 201 and disposed on the side of the call microphone 100 facing the pickup channel 202. The call tuning component 300 has a call tuning hole 301 connecting the pickup channel 202 and the call receiving hole 101. The radial dimension of the call tuning hole 301 is larger than the radial dimension of the call receiving hole 101 and larger than the cross-sectional dimension of the pickup channel 202. It should be noted that the sound entering through the pickup channel 202 passes through the call tuning hole 301 and is then received by the call receiving hole 101 of the call microphone 100. When the sound passes through the call tuning hole 301, the call tuning component 300 can perform sound homogenization processing to limit sharp tones from entering the call receiving hole 101 of the call microphone 100. By setting the radial dimension of the call tuning hole 301 to be larger than that of the call receiver hole 101 and also larger than the cross-sectional dimension of the pickup channel 202, the call tuning hole 301 can receive all the sound passing through it, thereby effectively ensuring the tuning effect of the call tuning component 300. Therefore, by adopting the above solution, the acoustic performance of the headphones can be further improved.

[0051] Please see Figure 2 , Figure 4 , Figure 7 In this embodiment, the housing 200 has a noise reduction receiving hole 205 on its inner side, and a sound receiving channel 206 communicating with the outside is provided at the bottom of the noise reduction receiving hole 205. The noise reduction receiving hole 205 and the call receiving cavity 201 are located opposite each other on both sides of the housing 200. The earphone also includes a noise reduction microphone 400 and a sealing cover 500.

[0052] The noise-reducing microphone 400 is disposed inside the noise-reducing receiving hole 205 and is used to achieve noise reduction; the sealing cover 500 is sleeved on the outside of the noise-reducing microphone 400 and is used to seal the noise-reducing microphone 400 and the noise-reducing receiving hole 205; the sealing cover 500 has a sealing receiving port 501 on its side facing the receiving channel 206, which is aligned with and penetrates the receiving channel 206; the noise-reducing microphone 400 has a plurality of noise-reducing receiving holes 401 on its side facing the sealing receiving port 501 and in the corresponding area of ​​the sealing receiving port 501.

[0053] It should be noted that when the noise-canceling microphone 400 is housed within the noise-canceling receiving hole 205, its noise-canceling receiving holes 401 are aligned with the sealed receiving port 501 and the receiving channel 206. The noise-canceling microphone 400 can receive noise signals entering the housing 200 from the outside through the receiving channel 206 and the sealed receiving port 501, process the noise signals, and emit a sound signal opposite to the noise signal after processing, so as to cancel the noise signal. This can effectively reduce the interference of noise on the audio collected by the call microphone 100, which is conducive to further improving the acoustic performance of the headphones.

[0054] It should also be noted that the noise-canceling microphone 400 and the call microphone 100 are positioned opposite each other on both sides of the housing 200. This arrangement helps to reduce the impact between the noise-canceling microphone 400 and the call microphone 100, thereby enabling the noise-canceling microphone 400 to achieve better noise reduction and the call microphone 100 to achieve better call quality.

[0055] It should also be noted that in this embodiment, a sealing cover 500 is fitted over the noise-canceling microphone 400. The sealing cover 500 is made of a soft material and has a certain degree of elasticity. When the noise-canceling microphone 400 with the sealing cover 500 fitted is placed inside the noise-canceling receiving hole 205, the sealing cover 500 can elastically abut against the outer surface of the noise-canceling microphone 400 and elastically abut against the inner surface of the noise-canceling receiving hole 205, thereby ensuring a sealed contact between the noise-canceling microphone 400 and the noise-canceling receiving hole 205. Based on this, it can effectively prevent airflow, audio, and noise signals entering from the sound receiving channel 206 from bypassing the noise-canceling microphone 400 and entering the housing 200 through the gap between the noise-canceling microphone 400 and the noise-canceling receiving hole 205. This improves the acoustic sealing, reduces the acoustic data difference of the noise signal collected by the noise-canceling microphone 400, improves the accuracy of noise signal analysis, ensures and improves the noise-canceling effect of the noise-canceling microphone 400, and further improves the acoustic performance of the headphones.

[0056] Optionally, the noise-canceling microphone 400 with the sealing cover 500 is interference-fitted with the noise-canceling receiving hole 205. This arrangement can further ensure and improve the sealing between the noise-canceling microphone 400 and the noise-canceling receiving hole 205, thereby further reducing the acoustic data difference of the noise signal collected by the noise-canceling microphone 400, further ensuring and improving the noise-canceling effect of the noise-canceling microphone 400, and further improving the acoustic performance of the headphones.

[0057] Optionally, the sealing cover 500 is made of silicone. This design allows the sealing cover 500 to have better elastic resistance, thereby further ensuring and improving the sealing between the noise-canceling microphone 400 and the noise-canceling receiving hole 205. This further reduces the acoustic data difference of the noise signal collected by the noise-canceling microphone 400, thereby further ensuring and improving the noise-canceling effect of the noise-canceling microphone 400 and further improving the acoustic performance of the headphones.

[0058] Please see Figure 2 , Figure 4 , Figure 7In this embodiment, the housing 200 has a first sound-receiving hole 2061 at the bottom of the noise-reducing receiving hole 205, and a second sound-receiving hole 2062 communicating with the outside is formed at the bottom of the first sound-receiving hole 2061. The first sound-receiving hole 2061 and the second sound-receiving hole 2062 together form a sound-receiving channel 206. The cross-sectional dimension of the second sound-receiving hole 2062 is larger than that of the first sound-receiving hole 2061. It should be noted that the external noise signal is first transmitted to the first sound-receiving hole 2061 through the second sound-receiving hole 2062, and then transmitted to the noise-reducing sound-receiving holes 401 of the noise-reducing microphone 400 through the first sound-receiving hole 2061. By setting the cross-sectional size of the second microphone hole 2062 to be larger than that of the first microphone hole 2061, noise signals can be received diffusely through the larger second microphone hole 2062, thus expanding its noise signal reception range. Then, the noise signal is transmitted to the noise-canceling microphone 400 through the first microphone hole 2061 in a concentrated manner, thereby concentrating the noise signal transmitted through the first microphone hole 2061 and improving the completeness and clarity of the noise signal collected by the noise-canceling microphone 400. Therefore, by adopting the above scheme, the noise-canceling effect of the noise-canceling microphone 400 can be further improved, which is beneficial for further improving the acoustic performance of the headphones.

[0059] Please see Figure 2 , Figure 4 , Figure 7 In this embodiment, the earphone also includes a noise-reducing tuning component 600 housed within a noise-reducing receiving hole 205 and disposed between the sealing cover 500 and the bottom of the noise-reducing receiving hole 205. The noise-reducing tuning component 600 has a noise-reducing tuning hole 601 connecting the sealed receiving port 501 and the pickup channel 202. The radial dimension of the noise-reducing tuning hole 601 is smaller than the cross-sectional dimension of the sealed receiving port 501 and larger than the cross-sectional dimension of the pickup channel 202. It should be noted that the noise signal entering through the receiving channel 206 will pass through the noise-reducing tuning hole 601 and then be received by the noise-reducing receiving holes 401 of the noise-reducing microphone 400. When the noise signal passes through the noise-reducing tuning hole 601, the noise-reducing tuning component 600 can perform homogenization processing on the noise signal to limit the noise signal exceeding the processing frequency band of the noise-reducing microphone 400 from entering the noise-reducing receiving holes 401 of the noise-reducing microphone 400. By setting the radial dimension of the noise-canceling tuning hole 601 to be smaller than the cross-sectional dimension of the sealed microphone port 501 and larger than the cross-sectional dimension of the pickup channel 202, the noise-canceling tuning hole 601 can completely receive and transmit noise signals passing through it, thereby effectively ensuring the tuning effect of the noise-canceling tuning component 600. Therefore, by adopting the above solution, the noise-canceling effect of the noise-canceling microphone 400 can be further guaranteed, and the acoustic performance of the headphones can be further improved.

[0060] Please see Figure 1 , Figure 2In this embodiment, the headphones also include a touch screen 700 connected to the housing 200 and for user touch. The touch screen 700 includes a protective part 710 connected to the housing 200 and a touch part 720 recessed relative to the protective part 710. It should be noted that the touch screen 700 allows the user to control the headphones by touching it when the headphones are worn in the ear canal, such as turning the headphones on, off, pausing, playing, switching audio, and adjusting volume, thereby significantly improving the headphones' performance and ease of use. It should also be noted that the protective part 710 is connected to the outer periphery of the touch part 720. The protective part 710 connects the touch part 720 to the housing 200 and provides protection for the touch part 720, ensuring its lifespan. By recessing the touch unit 720 relative to the protective unit 710, on the one hand, it allows users to quickly and accurately access the touch unit 720 and perform touch operations on the headphones, thereby further improving the performance of the headphones; on the other hand, it effectively reduces the risk of wear and tear on the touch unit 720, thereby further extending the service life of the touch unit 720 and ensuring the performance and ease of operation of the headphones.

[0061] Please see Figure 1 , Figure 2 In this embodiment, the touch screen 700 is located between the microphone 100 and the noise-canceling microphone 400, and the surface of the touch unit 720 facing away from the housing 200 is tilted towards the microphone 100. It should also be noted that, traditionally, to ensure the sound collection effect of the microphone 100, when the headset is worn in the user's ear canal, the microphone 100 is often positioned relatively close to the front of the user's face, i.e., close to the source of the user's sound. Based on this, by adopting the above solution, the thickness of the side of the touch screen 700 connected to the noise-canceling microphone 400 is greater than the thickness of the side of the touch screen 700 connected to the microphone 100, so that the touch surface of the touch unit 720 is positioned relatively towards the front of the user. This further facilitates the user to quickly and accurately touch the touch unit 720 and realize touch operation of the headset, thereby further improving the headset's usability and ease of operation.

[0062] Optionally, the touch unit 720 is positioned relatively close to the microphone 100, meaning the width of the protective unit 710 on the side closest to the microphone 100 is smaller than the width of the protective unit 710 on the side furthest from the microphone 100. This arrangement further facilitates the user in quickly and accurately accessing the touch unit 720 and performing touch operations on the headset, thereby further improving the headset's usability and ease of use.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
