Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement.

[0047] In existing headphone designs, a light guide is typically used to indicate the headphone's operating status, such as charging and connection status, while a microphone is used to pick up the user's voice signals. To achieve both light indication and voice pickup, related technologies often use separate light guides and microphones. This not only increases the space inside the headphone, but also complicates the structure, increasing manufacturing difficulty and cost.

[0048] In view of this, see Figures 1-8 In an embodiment of the present invention, a sound receiving device 100 is provided, and the sound receiving device 100 includes a shell 110, a microphone 120, a connector 130, and a light-emitting component 140. In addition to realizing the sound receiving function, the sound receiving device 100 in the present invention can also realize other related functions such as calls and recording. Exemplarily, the sound receiving device 100 can be used for headphones 200 (specifically, it can be one of wireless headphones 200, wired headphones 200, headphones 200, in-ear headphones 200, ear-hook headphones 200, open headphones 200, sports headphones 200, bone conduction headphones 200), landline phones, recorders, voice recorders, intercoms, microphones, sound cards, VR headsets and other devices.

[0049] See also Figures 1-4 The housing 110 defines an inner cavity 111, which has a first opening 112 connecting the outside world to the inner cavity 111. The cross-section of the first opening 112 can have any suitable shape as needed. Therefore, the microphone 120, the connector 130, and the light-emitting element 140 are all located in the inner cavity 111. The outside world, as described in this utility model, is defined as the external environment outside the sound receiving device 100 itself. The microphone 120 has a sensing opening 121, which is suitable for collecting sound signals. It is understood that when sound is generated in the surrounding environment, the sound propagates through the air in the form of sound waves. The sensing opening 121 serves as a sound receiving hole for the microphone 120 to collect the sound signal. The sensing opening 121 allows the sound waves to enter the interior of the microphone 120, allowing the microphone 120 to sense the sound signal. It should be noted that the function of collecting sound signals described in this utility model can specifically be used to record sound to facilitate functions such as phone calls and audio recordings, or it can also be used to sense the presence of sound in the outside world, or to sense the decibel level or frequency of the sound. Furthermore, in some embodiments, the microphone 120 may have multiple sensing openings 121. In this case, the various configurations of the sensing openings 121 of the present invention may be applied to only one of the sensing openings 121 or may be adapted to all of the sensing openings 121. Depending on the needs, the sensing openings 121 may have any suitable shape and are not limited here.

[0050] See also Figure 3-Figure 4 Connector 130 is provided with a first channel 131, one end of which is connected to first opening 112 and the other end of which is connected to sensing opening 121. It will be appreciated that this arrangement allows sensing opening 121 to be connected to the outside world through first channel 131, enabling sensing opening 121 to collect external sound signals. As desired, first channel 131 can have any cross-sectional shape and extend along any suitable trajectory.

[0051] See also Figure 3-Figure 4The light-emitting element 140 is configured to emit light, so that the light passes through the connecting member 130 and the first opening 112 and reaches the outside world. Specifically, the light-emitting element 140 can be a light-emitting diode (LED) or other device capable of emitting light. By allowing the light emitted by the light-emitting element 140 to pass through the connecting member 130 and the first opening 112 and reach the outside world, the light-emitting element 140 can serve as a light indicator. The above-mentioned light indicator function can be specifically used for different needs, such as for indicating the working status, charging status, connection status, etc. of the sound receiving device 100. Combining the arrangement of the light-emitting element 140 with the above-mentioned connection arrangement of the microphone 120, it can be understood that the sensing opening 121 of the microphone 120 and the light emitted by the light-emitting element 140 are both connected to the outside world through the first opening 112, so that the first opening 112 can play the role of collecting sound signals and providing light indication. The number of openings in the shell 110 is reduced, which is conducive to saving processing costs and difficulty, making the sound receiving device 100 more streamlined and beautiful. At the same time, it also simplifies the internal structure of the sound receiving device 100, making the layout space of the accommodating cavity 133 more sufficient.

[0052] As can be seen, the sound receiving device 100 of the present invention includes a housing 110, a microphone 120, a connector 130, and a light-emitting element 140. The interior 111 of the housing 110 has a first opening 112 that connects the interior 111 to the outside world. To address the dual functional requirements of collecting sound signals and providing light indication, the present invention provides a first channel 131 in the connector 130, connecting one end of the channel to the first opening 112 and the other end to the sensing opening 121. Furthermore, the present invention allows light emitted by the light-emitting element 140 to pass through the connector 130 and the first opening 112 and reach the outside world. Compared to related art designs that provide separate channels connecting the sound pickup module and the light indication module to the outside world, the present invention provides both the sensing opening 121 provided on the microphone 120 and the light emitted by the light-emitting element 140 to the outside world through the first opening 112. This makes the sound receiving device 100 more streamlined and aesthetically pleasing. Furthermore, the simplified internal structure of the sound receiving device 100 also provides more space for the accommodation chamber 133. Therefore, the sound receiving device 100 of the present invention simplifies the structural arrangement of the microphone 120 and the light emitting element 140 , so that the arrangement space of the accommodating cavity 133 is more sufficient.

[0053] In order to achieve the effect of light passing through the connecting member 130, see Figure 4 or Figure 5In one type of setting, the transmittance of the connector 130 is greater than or equal to 80% and less than or equal to 92%, so that the light can pass through the connector. Exemplarily, the transmittance of the connector 130 can be one of 80%, 85%, 90%, and 92%. To put it another way, in some embodiments, the material of the connector 130 is a light-transmitting material, so that light can pass through the connector 130. The light-transmitting material can be one of rubber, silicone, glass, plastic, organic polymer, and composite material. It can be understood that by setting the connector 130 to meet the above-mentioned transmittance range, the light emitted by the light-emitting component 140 can utilize the physical properties of the material of the connector 130, so that the light can penetrate the connector 130. This setting makes it unnecessary to set up additional structures for the conduction of light, and makes it easier to arrange the light-emitting component 140. At the same time, by limiting the upper limit of the transmittance of the connector 130, the manufacturing cost of the connector 130 can also be saved. See Figure 8 According to the requirements, the light emitting element 140 can be arranged at any position adjacent to the connecting element 130, and the light emitting element 140 can be connected to the connecting element 130 or not. Figure 6 In another configuration, the connector 130 is provided with a second channel 132, one end of which connects to the light-emitting element 140 and the other end connects to the first opening 112. It will be appreciated that the provision of the second channel 132 allows light to pass through the second channel 132 and the first opening 112 and reach the outside world. This configuration allows the second channel 132 to effectively guide the light, thereby enhancing the intensity of the light emitted from the first opening 112. To enhance light transmission, in some embodiments, the extension path of the second channel 132 may be a straight line. In other embodiments, the extension path of the second channel 132 may include a curve, depending on the needs. In conjunction with the configuration of the first channel 131 in the aforementioned embodiment, in some embodiments, the second channel 132 may connect to one side of the first channel 131, so that light emitted by the light-emitting element 140 first passes through the second channel 132 and, after reaching the intersection of the second channel 132 and the first channel 131, passes through the first channel 131 and the first opening 112 and reaches the outside world.

[0054] In order to reduce the influence of the first opening 112 on the sound receiving effect of the microphone 120, see Figure 4In some embodiments, when viewed along the axial direction L of the first opening 112, the first opening 112 is spaced apart from the sensing opening 121. In other words, the above definition means that the orthographic projection of the opening edge of the first opening 112 on a projection plane perpendicular to the axial direction L is spaced apart from the orthographic projection of the opening edge of the sensing opening 121 on the projection plane. It is understood that the above arrangement causes the first opening 112 and the sensing opening 121 to be offset from each other. To achieve the effect of the offset between the first opening 112 and the sensing opening 121, the extension trajectory of the first channel 131 can be a curve, thereby changing the direction of the airflow entering the first channel 131 from the first opening 112. When passing through the first channel 131, the flow rate of the airflow is reduced, effectively dispersing and weakening the noise generated by the airflow. As a result, the voice signal picked up by the microphone 120 is clearer and more accurate, significantly improving call quality.

[0055] For the specific structure of the first channel 131, see Figure 4 In some embodiments, the first channel 131 includes a first portion 1311 and a second portion 1312. The first portion 1311 extends along the axial direction L of the first opening 112, while the second portion 1312 extends perpendicular to the axial direction L. It should be understood that the above definition means that the cross-section of the wall defining the first channel 131 in the direction perpendicular to the axial direction L is L-shaped, with the first portion 1311 and the second portion 1312 corresponding to the two sides of the L-shape. The above arrangement of the first portion 1311 and the second portion 1312 allows the first portion 1311 to buffer airflow entering through the first opening 112, effectively dispersing and reducing noise generated by the airflow. The airflow then passes through the second portion 1312 and reaches the sensing opening 121. Furthermore, the arrangement of the first channel 131 consisting solely of the first portion 1311 and the second portion 1312, extending perpendicularly to each other, allows the first channel 131 to function as an airflow buffer while maintaining a minimal structure, thereby minimizing the space occupied by the connector 130. In addition, see Figure 7 In other embodiments, the first channel 131 may extend along a curved trajectory of any shape.

[0056] In order to further improve the space utilization of the inner cavity 111, on the one hand, see Figure 4 In some embodiments, the connector 130 is provided with a receiving cavity 133, and the light emitting element 140 is received in the receiving cavity 133; on the other hand, see Figure 5In some embodiments, the microphone 120 is accommodated in the second channel 132. It will be appreciated that the above two configurations utilize the structure of the connector 130 to accommodate the light-emitting element 140 or the microphone 120, thereby fully utilizing the space in the inner cavity 111 and preventing the connector 130 from overlapping with the light-emitting element 140 or the microphone 120 and occupying excessive space. In other embodiments, the light-emitting element 140 and / or the microphone 120 may be stacked with the connector 130 along the axial direction L, as desired.

[0057] Based on the accommodation cavity 133 set in the above embodiment, see Figure 4 In some embodiments, one end of the accommodating cavity 133 is connected to the end of the connector 130 that is away from the first opening 112 along the axial direction L of the first opening 112, and the other end is recessed toward the first opening 112. This arrangement allows the accommodating cavity 133 to be located at the end of the connector 130 that is away from the first opening 112. Therefore, when the connector 130 and the light-emitting element 140 are mated, it is only necessary to stack the connector 130 and the light-emitting element 140 along the axial direction L. This simplifies the operation, and the accommodating cavity 133 occupies a smaller space in the connector 130, thereby making it easier to arrange the first channel 131.

[0058] For the specific location of microphone 120, see Figure 4 In some embodiments, the sound receiving device 100 further includes a circuit board 150, which is provided with a third channel 151. Along the axial direction L of the first opening 112, one side of the third channel 151 connects to the first channel 131, and the other side connects to the microphone 120 and connects to the sensing opening 121. It will be appreciated that this arrangement allows the microphone 120 to be positioned on the side of the circuit board 150 facing away from the connector 130. Furthermore, to enable the sensing opening 121 to sense sound signals, the third channel 151 is provided on the circuit board 150, connecting the first channel 131 and the sensing opening 121. On the one hand, the above arrangement provides ample space for assembly and disassembly of the microphone 120 and the circuit board 150, making assembly and disassembly of the microphone 120 more convenient. On the other hand, the arrangement of the microphone 120 does not occupy the space on the side where the connector 130 is located, thereby making it easier to arrange the connector 130 and avoiding the problem of excessive wind noise caused by the microphone 120 being too close to the first opening 112 after the microphone 120 is arranged on the side of the circuit board 150 close to the connector 130.

[0059] In addition, see Figure 4 In some embodiments, the light emitting member 140 may be connected to a side of the circuit board 150 that is close to the connecting member 130 along the axial direction L.

[0060] In some embodiments, the connector 130 is configured to be deformable when subjected to force. On the one hand, the above arrangement allows the connector 130 to rely on deformation to form its own assembly and positioning; on the other hand, it also allows the connector 130 to have a larger installation margin when installed in conjunction with other parts. For example, combined with the arrangement of the accommodating cavity 133 in the above embodiment, when it is necessary to accommodate the light-emitting component 140 in the accommodating cavity 133 during the assembly process, the deformable connector 130 can increase the assembly margin of the two and make the assembly operation more convenient. Based on the arrangement of the connector 130 being deformable, see Figure 8 In some embodiments, the first channel 131 includes a first portion 1311, which is located at the end of the first channel 131 along the axial direction L, close to the circuit board 150. In other words, the first portion 1311 is the portion of the first channel 131 that faces and connects to the third channel 151. Both the first portion 1311 and the third channel 151 extend along the axial direction L. In a direction perpendicular to the axial direction L, the maximum dimension of the first portion 1311 is W1, and the maximum dimension of the third channel 151 is W2, satisfying the following relationship: W1 - W2 ≥ 0.2 mm. This dimensioning ensures that, to a certain extent, the outflow area of ​​the squeezed first channel 131 will not be smaller than the outflow area of ​​the third channel 151 when the connector 130 deforms. This ensures that the first channel 131 will not be affected by the deformation and block the third channel 151, thereby affecting the ability of the sensor opening 121 to collect sound signals.

[0061] See also Figure 4 In some embodiments, the connector 130 includes an annular protrusion 134, which is located at the end of the connector 130 along the axial direction L that is closest to the circuit board 150. The annular protrusion 134 surrounds one end of the first channel 131 that faces the third channel 151, and the annular protrusion 134 abuts the circuit board 150. It is understood that, on the one hand, the annular protrusion 134 can be used in the connection process between the connector 130 and the circuit board 150. For example, the annular protrusion 134 can be used to press-fit the connector 130 onto the circuit board 150, making the assembly between the connector 130 and the circuit board 150 more convenient and reliable, and improving the sealing performance. On the other hand, the annular protrusion 134 can also be used for positioning the connector 130 and the circuit board 150 during installation.

[0062] The second aspect of the present invention further provides an earphone 200, comprising the sound receiving device 100 according to any of the above embodiments. The earphone 200 can be a wireless earphone 200, a wired earphone 200, a headset 200, an in-ear earphone 200, an ear-hook earphone 200, an open-ear earphone 200, a sports earphone 200, or a bone conduction earphone 200.

[0063] See also Figure 1or Figure 2 In some embodiments, the first opening 112 can be set on the end surface of the earphone 200 facing away from the earplug along the direction of the user's ear hole. The above setting can reduce the wind volume at the first opening 112, thereby reducing wind noise and being more suitable for collecting sound signals around the user.

[0064] Thanks to the improvements made to the sound receiving device 100 in the above embodiments, the earphone 200 in the second embodiment of the present invention has the same technical effects as the sound receiving device 100 in the above embodiments, which will not be described in detail here.
