Description
Technical Field
[0001] This application belongs to the technical field of wearable devices, specifically relating to a microphone assembly and a wearable device. Background Technology
[0002] In related technologies, wearable devices are equipped with microphones to meet their call requirements. The microphone is always in a pickup state; that is, even when the wearable device does not need to pick up sound, the microphone is still acquiring audio. This increases the product's power consumption and shortens the microphone's lifespan. Summary of the Invention
[0003] This application aims to provide a microphone assembly and a wearable device, which at least solves the technical problems in the related art, such as high energy consumption and short lifespan of the microphone due to the microphone being in a constant state of sound pickup.
[0004] To solve the above-mentioned technical problems, this application is implemented as follows:
[0005] In a first aspect, embodiments of this application provide a microphone assembly for a wearable device. The microphone assembly includes: a fixed structure having a blocking part and a connecting part, the connecting part being electrically connected to the wearable device; a microphone being movably connected to the fixed structure, the microphone having a conductive part and a circuit board, the conductive part being electrically connected to the circuit board, and the microphone being movable relative to the fixed structure between a first position and a second position; when the microphone is in the first position, the conductive part is connected to the blocking part, and when the microphone is in the second position, the conductive part is electrically connected to the connecting part.
[0006] Secondly, embodiments of this application provide a wearable device, including a microphone assembly as described in any of the embodiments of the first aspect.
[0007] In embodiments of this application, the microphone assembly includes a fixed structure and a microphone.
[0008] The fixed structure has a blocking part and a connecting part. The connecting part is electrically connected to the wearable device, while the blocking part is not electrically connected to the wearable device.
[0009] The microphone is movably connected to a fixed structure. The microphone has a conductive part and a circuit board, which are electrically connected. The microphone is movable relative to the fixed structure, moving between a first position and a second position.
[0010] When the microphone is not needed, it is moved to the first position, connecting the conducting part to the blocking part. At this time, the microphone's circuit board cannot be electrically connected to the wearable device. In other words, when the microphone is in the first position, it will not interact with the wearable device, thus reducing the wearable device's power consumption and saving its electricity.
[0011] When the microphone is needed to work, it is moved to the second position, so that the conductive part and the connecting part are electrically connected. At this time, the microphone's circuit board is electrically connected to the wearable device. In other words, when the microphone is in the second position, it can acquire sound sources to meet the usage needs of the wearable device for making calls.
[0012] In other words, the position of the microphone and the fixed structure can be adjusted according to usage needs. Specifically, by adjusting the position of the microphone, the working state of the microphone can be adjusted to achieve electrical connection between the microphone and the wearable device, or to disconnect the microphone from the wearable device. This balances the energy consumption and call requirements of the wearable device, which is conducive to improving the product's performance and market competitiveness.

[0033] The following is combined Figures 1 to 12 This application describes a microphone assembly 100 and a wearable device 300 according to embodiments thereof.
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a microphone assembly 100 according to some embodiments of this application is used in a wearable device 300. The microphone assembly 100 includes: a fixing structure 110, which has a blocking portion 112 and a connecting portion 114, the connecting portion 114 being electrically connected to the wearable device 300; a microphone 130, which is movably connected to the fixing structure 110, the microphone 130 having a conducting portion 132 and a circuit board 134, the conducting portion 132 being electrically connected to the circuit board 134, and the microphone 130 being movable relative to the fixing structure 110 between a first position and a second position; when the microphone 130 is in the first position, the conducting portion 132 is connected to the blocking portion 112, and when the microphone 130 is in the second position, the conducting portion 132 is electrically connected to the connecting portion 114.
[0035] In this embodiment, the microphone assembly 100 includes a fixing structure 110 and a microphone 130.
[0036] The structure is fixed with a blocking part 112 and a connecting part 114. The connecting part 114 is electrically connected to the wearable device 300 (e.g., the motherboard 320 of the wearable device 300), while the blocking part 112 is not electrically connected to the motherboard 320 of the wearable device 300.
[0037] The microphone 130 is movably connected to the fixed structure 110. The microphone 130 has a conductive part 132 and a circuit board 134, which are electrically connected. The microphone 130 is movable relative to the fixed structure 110 to move between a first position and a second position.
[0038] When microphone 130 is not needed, it is moved to the first position, so that the conducting part 132 is connected to the blocking part 112. At this time, the circuit board 134 of microphone 130 cannot be electrically connected to the motherboard 320 of wearable device 300. In other words, when microphone 130 is in the first position, microphone 130 will not interact with motherboard 320. This will reduce the power consumption of wearable device 300 and save power.
[0039] When microphone 130 is needed to work, it is moved to the second position, so that the conducting part 132 is electrically connected to the connecting part 114. At this time, the circuit board 134 of microphone 130 is electrically connected to the main board 320 of wearable device 300. That is to say, when microphone 130 is in the second position, microphone 130 can obtain sound source to meet the call usage needs of wearable device 300.
[0040] In other words, the matching position of the microphone 130 and the fixed structure 110 can be adjusted according to usage needs. Specifically, by adjusting the position of the microphone 130, the working state of the microphone 130 can be adjusted to achieve electrical connection between the microphone 130 and the motherboard 320, or to disconnect the electrical connection between the microphone 130 and the motherboard 320. In this way, the power consumption and call requirements of the wearable device 300 are taken into account, which is conducive to improving the performance and market competitiveness of the product.
[0041] In some embodiments, the microphone 130 is rotatably connected to the fixed structure 110.
[0042] In this embodiment, the cooperation structure between the microphone 130 and the fixed structure 110 is further defined. Specifically, the microphone 130 is rotatably connected to the fixed structure 110, and the microphone 130 rotates relative to the fixed structure 110 to move between a first position and a second position.
[0043] In some other embodiments, the microphone 130 is slidably connected to the fixed structure 110.
[0044] In some embodiments, such as Figure 7 As shown, the microphone assembly 100 also includes: a pivot 150, a fixing structure 110 and a microphone 130 rotatably connected via the pivot 150.
[0045] In this embodiment, the microphone assembly 100 further includes a pivot 150, which connects the fixed structure 110 and the microphone 130 to meet the usage requirements of rotating connection between the microphone 130 and the fixed structure 110.
[0046] In this embodiment, the rotating shaft 150 is disposed on the fixed structure 110, and the microphone 130 is rotatably connected to the rotating shaft 150.
[0047] In some other embodiments, the microphone 130 is provided with a protrusion, and the fixing structure 110 is provided with a connection hole, into which the protrusion is inserted.
[0048] In some embodiments, such as Figure 7 As shown, the microphone assembly 100 also includes a driver 160, which is electrically connected to the circuit board 134 and is used to drive the microphone 130 to rotate relative to the fixed structure 110.
[0049] In this embodiment, the microphone 130 further includes a driver 160, which is electrically connected to the circuit board 134 to meet the data transmission requirements between the driver 160 and the circuit board 134. The driver 160 is used to drive the microphone 130 to rotate relative to the fixed structure 110; that is, the driver 160 can be used to automatically drive the microphone 130 to rotate relative to the fixed structure 110. This configuration improves the automation level of the microphone assembly 100.
[0050] Specifically, the drive component 160 includes a motor, pump body, etc., which will not be listed here.
[0051] In some other embodiments, the user can manually drive the microphone 130 to rotate relative to the fixed structure 110. That is, the microphone 130 can be driven to rotate relative to the fixed structure 110 in a manual and / or automatic manner.
[0052] In some embodiments, such as Figure 10 and Figure 11 As shown, the microphone 130 includes a first microphone 130a and a second microphone 130b, and the fixing structure 110 is located between the first microphone 130a and the second microphone 130b. Both the first microphone 130a and the second microphone 130b include an N-pole portion 170, a S-pole portion 180 and a voice coil 360. The voice coil 360 of the first microphone 130a is located in the N-pole portion 170 of the first microphone 130a, and the voice coil 360 of the second microphone 130b is located in the S-pole portion 180 of the second microphone 130b. The S-pole portion 180 of the first microphone 130a is close to the N-pole portion 170 of the second microphone 130b, and the N-pole portion 170 of the first microphone 130a is far away from the S-pole portion 180 of the second microphone 130b.
[0053] In this embodiment, the structure of the microphone 130 is defined as follows: the microphone 130 includes a first microphone 130a and a second microphone 130b. The first microphone 130a is located on a first side of the fixing structure 110. The second microphone 130b is located on a second side of the fixing structure 110. That is, the fixing structure 110 is located between the first microphone 130a and the second microphone 130b.
[0054] The first microphone 130a includes an N-pole portion 170, a S-pole portion 180, and a voice coil 360. The second microphone 130b includes an N-pole portion 170, a S-pole portion 180, and a voice coil 360. The voice coil 360 of the first microphone 130a is located at the N-pole portion 170, and the voice coil 360 of the second microphone 130b is located at the S-pole portion 180. Furthermore, the S-pole portion 180 of the first microphone 130a is closer to the N-pole portion 170 of the second microphone 130b, and the N-pole portion 170 of the first microphone 130a is further away from the S-pole portion 180 of the second microphone 130b. In other words, the magnets inside the microphones 130 are symmetrically distributed, with the N-pole portion 170 of the first microphone 130a facing outwards and the S-pole portion 180 of the first microphone 130a facing inwards, and the voice coil 360 is wound around the N-pole portion 170. The second microphone 130b has its N-pole 170 facing inward and its S-pole 180 facing outward, with the voice coil 360 wound around the S-pole 180. One of the signals can be used as the audio source.
[0055] In this embodiment, there is one first microphone 130a and one second microphone 130b.
[0056] In some other embodiments, the number of first microphones 130a is one, and the number of second microphones 130b is multiple.
[0057] In some other embodiments, there are multiple first microphones 130a and one second microphone 130b.
[0058] In some other embodiments, there are multiple first microphones 130a and multiple second microphones 130b.
[0059] In some embodiments, such as Figure 12 As shown, one of the first microphone 130a and the second microphone 130b is provided with a recess 190, and the other of the first microphone 130a and the second microphone 130b is provided with a protrusion 200, and the protrusion 200 is snapped into connection with the recess 190.
[0060] In this embodiment, the mating structure of the first microphone 130a and the second microphone 130b is further defined. Specifically, one of the first microphone 130a and the second microphone 130b has a recess 190, and the other of the first microphone 130a and the second microphone 130b has a protrusion 200. That is, the first microphone 130a has a recess 190, and the second microphone 130b has a protrusion 200. Alternatively, the first microphone 130a has a protrusion 200, and the second microphone 130b has a recess 190. The protrusion 200 and the recess 190 are snap-fitted together so that the first microphone 130a and the second microphone 130b are assembled together. In other words, the first microphone 130a and the second microphone 130b are combined together.
[0061] When the ambient noise does not affect the microphone 130's sound pickup, the protrusion 200 and the recess 190 engage to make the microphones 130 a single channel. The first microphone 130a and the second microphone 130b on both sides of the fixed structure 110 are combined together through the recess 190 and the protrusion 200 to reduce the space occupied by the microphones 130, which helps to enhance the structural strength of the microphone assembly 100 and improve the product's resistance to deformation.
[0062] Of course, the assembly methods of the first microphone 130a and the second microphone 130b include, but are not limited to, snap-fit connections, and may also include screw connections and fastening connections with fasteners, etc., which will not be listed here.
[0063] In some embodiments, either the first microphone 130a or the second microphone 130b is movable relative to the fixed structure 110 along the axial direction of the pivot 150.
[0064] In this embodiment, the mating structure of the first microphone 130a, the second microphone 130b, and the rotating shaft 150 is further defined, such that either the first microphone 130a or the second microphone 130b can move relative to the fixed structure 110 along the axial direction of the rotating shaft 150. That is, the first microphone 130a can move relative to the fixed structure 110 along the axial direction of the rotating shaft 150, and the second microphone 130b can move relative to the fixed structure 110 along the axial direction of the rotating shaft 150. In other words, the distance between the first microphone 130a and the second microphone 130b is adjustable along the axial direction of the rotating shaft 150.
[0065] When the ambient noise does not affect the microphone 130's sound pickup, the first microphone 130a can be placed close to the second microphone 130b.
[0066] When ambient noise affects the sound pickup of microphone 130, the pickup range of microphone 130a and / or microphone 130b can be adjusted by moving the first microphone 130a and / or the second microphone 130b to separate them into two independent microphones 130. Figure 11 As shown, the distance between the first microphone 130a and the second microphone 130b is d, and the audio signals from the first microphone 130a and the second microphone 130b can be used for compensation in other algorithms. The audio signals from the first microphone 130a and the second microphone 130b form a stable phase difference, which, combined with the software's noise reduction algorithm, achieves the purpose of noise reduction.
[0067] In some embodiments, such as Figure 1 and Figure 10 As shown, the microphone 130 includes: a main body structure 140, which is movably connected to the fixed structure 110, and the main body structure 140 is provided with a conductive part 132; a connecting arm 142, which is connected to the main body structure 140, and the connecting arm 142 is provided with a circuit board 134 and a sound outlet 144.
[0068] In this embodiment, the microphone 130 includes a body structure 140 and a connecting arm 142.
[0069] The main body structure 140 is movably connected to the fixed structure 110, that is, the position of the main body structure 140 relative to the fixed structure 110 is adjustable.
[0070] Furthermore, the connecting arm 142 is connected to the main body structure 140. The connecting arm 142 is equipped with a circuit board 134 and a sound outlet 144. That is, the connecting arm 142 serves as a mounting carrier for the circuit board 134 and the sound outlet 144, and has the function of mounting and fixing the circuit board 134 and the sound outlet 144.
[0071] In some embodiments, the connecting arm 142 is a flexible arm, which can move the sound outlet 144 away from or closer to the fixed structure 110.
[0072] In this embodiment, the structure of the connecting arm 142 is further defined. Specifically, the connecting arm 142 is a flexible arm, that is, the shape of the connecting arm 142 is adjustable, and the position of the sound outlet 144 can be adjusted by adjusting the shape of the connecting arm 142. The position of the sound outlet 144 can be adaptively adjusted according to the specific sound pickup range requirements to meet diverse usage needs.
[0073] Specifically, the connecting arms 142 of the first microphone 130a and / or the second microphone 130b can be bent to separate the connecting arms 142 of the first microphone 130a and the second microphone 130b, making them two independent microphones 130, so as to adjust the pickup range of the first microphone 130a and the second microphone 130b.
[0074] Specifically, the connecting arm 142 is provided with a support rib, which can be bent to adjust the shape of the connecting arm 142.
[0075] In some embodiments, such as Figure 6 As shown, the connecting part 114 is provided with a conductive spring 116, which is electrically connected to the wearable device 300.
[0076] In this embodiment, the connecting part 114 is provided with a conductive spring 116, which is electrically connected to the wearable device 300 (e.g., the motherboard 320 of the wearable device 300) via a connecting wire 350. Thus, when the microphone 130 is in the second position, the conductive part 132 of the microphone 130 contacts the conductive spring 116, thereby achieving an electrical connection between the circuit board 134 of the microphone 130 and the motherboard 320 of the wearable device 300.
[0077] Specifically, the conductive spring 116 is a metal sheet.
[0078] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, both the blocking part 112 and the connecting part 114 are provided with a plurality of grooves 118, and each groove 118 of the connecting part 114 is provided with a conductive spring piece 116; the conducting part 132 is provided with a plurality of conducting protrusions 133; when the microphone 130 is in the first position, each conducting protrusion 133 is inserted into a groove 118 of the blocking part 112, and when the microphone 130 is in the second position, each conducting protrusion 133 is inserted into a groove 118 of the connecting part 114.
[0079] In this embodiment, both the blocking part 112 and the connecting part 114 are provided with a plurality of grooves 118. That is, the blocking part 112 is provided with a plurality of grooves 118, the connecting part 114 is provided with a plurality of grooves 118, each groove 118 of the connecting part 114 is provided with a conductive spring piece 116, and each groove 118 of the blocking part 112 is not provided with a conductive spring piece 116.
[0080] The conductive part 132 is provided with a plurality of conductive protrusions 133, each conductive protrusion 133 engaging with a groove 118 in the blocking part 112 and a groove 118 in the connecting part 114. Specifically, when the microphone 130 is in the first position, each conductive protrusion 133 is inserted into a groove 118 in the blocking part 112, and when the microphone 130 is in the second position, each conductive protrusion 133 is inserted into a groove 118 in the connecting part 114.
[0081] The conducting protrusion 133 engages with the groove 118 of the blocking part 112, which increases the contact area between the conducting part 132 and the blocking part 112, thus ensuring a stable assembly between the conducting part 132 and the blocking part 112.
[0082] The conductive protrusion 133 engages with the groove 118 of the connecting portion 114, which increases the contact area between the conductive portion 132 and the connecting portion 114, thereby ensuring a stable assembly between the conductive portion 132 and the connecting portion 114.
[0083] In some embodiments, such as Figure 8 and Figure 9 As shown, the fixing structure 110 is also provided with a plurality of tracks 120, each track 120 connecting a groove 118 of the blocking part 112 and a groove 118 of the connecting part 114, each guiding protrusion 133 being slidably connected to a track 120; and / or the guiding part 132 is provided with a plurality of elastic members 138, each guiding protrusion 133 being connected to an elastic member 138, and the elastic member 138 abutting against the fixing structure 110.
[0084] In this embodiment, the fixing structure 110 is further provided with multiple tracks 120. Each track 120 connects a groove 118 of the blocking part 112 and a groove 118 of the connecting part 114. Each conductive protrusion 133 can slide within a track 120, that is, each conductive protrusion 133 engages with a groove 118 of the blocking part 112 and a groove 118 of the connecting part 114. When the microphone 130 moves from the first position to the second position, the conductive protrusion 133 moves from a groove 118 of the blocking part 112 to a groove 118 of the connecting part 114 via the track 120. When the microphone 130 moves from the second position to the first position, the conductive protrusion 133 moves from a groove 118 of the connecting part 114 to a groove 118 of the blocking part 112 via the track 120.
[0085] And / or, the conductive portion 132 is provided with a plurality of elastic elements 138, each conductive protrusion 133 cooperating with one elastic element 138. When the microphone 130 moves from the first position to the second position, and the conductive protrusion 133 moves from a groove 118 of the blocking portion 112 to a groove 118 of the connecting portion 114, the elastic element 138 is compressed to retract. After the conductive protrusion 133 moves to a groove 118 of the connecting portion 114, the elastic element 138 returns to its original position. Similarly, when the microphone 130 moves from the second position to the first position, and the conductive protrusion 133 moves from a groove 118 of the connecting portion 114 to a groove 118 of the blocking portion 112, the elastic element 138 is compressed to retract. After the conductive protrusion 133 moves to a groove 118 of the blocking portion 112, the elastic element 138 returns to its original position.
[0086] In some embodiments, such as Figure 7 and Figure 8 As shown, any two of the multiple conductive protrusions 133 have different volumes.
[0087] In this embodiment, the shape of the groove 118 is adapted to the shape of the conductive protrusion 133. For example, the shape of the groove 118 is hemispherical and the shape of the conductive protrusion 133 is spherical. Or, the shape of the groove 118 is elliptical and the shape of the conductive protrusion 133 is elliptical.
[0088] Since the microphone assembly 100 includes multiple connecting wires 350, each connecting wire 350 is connected to a conductive spring 116. When the microphone 130 is in the second position, each conductive protrusion 133 corresponds to one connecting wire 350. By setting the structure of multiple conductive protrusions 133 such that any two conductive protrusions 133 have different volumes, the distinguishability of the conductive part 132 is enhanced, which plays a role in preventing mistaken installation and reduces the probability of incorrect installation when the operator assembles the microphone assembly 100.
[0089] Specifically, such as Figure 7 and Figure 8 As shown, the microphone 130 has three conductive protrusions 133, which are spherical structures. The volume of the three spherical structures gradually decreases from the outside to the inside.
[0090] Of course, the number of conducting protrusions 133 of the microphone 130 is not limited to three, but can also be four, five, etc., which will not be listed here.
[0091] like Figure 1 As shown, a wearable device 300 according to some embodiments of the present application includes a microphone assembly 100 as described in any of the above embodiments.
[0092] The wearable device 300 according to the embodiments of this application includes the microphone assembly 100 of the above embodiments, and therefore has all the beneficial effects of the microphone assembly 100, which will not be described in detail here.
[0093] In some embodiments, such as Figure 1 As shown, the wearable device 300 also includes: a frame 310, a fixing structure 110 connected to the frame 310, a microphone 130 movably connected to the frame 310; and a motherboard 320 disposed inside the frame 310, which is electrically connected to the connecting part 114.
[0094] In this embodiment, the wearable device 300 also includes a frame 310 and a motherboard 320. The fixing structure 110 is connected to the frame 310 and the fixing structure 110 cannot move relative to the frame 310.
[0095] The microphone 130 is movably connected to the frame 310, and the microphone 130 can move relative to the frame 310 and the fixed structure 110. The motherboard 320 is electrically connected to the connection part 114 to meet the usage requirements of the microphone 130 being able to interact with the motherboard 320 when it is in the second position.
[0096] In addition, the frame 310 serves as a mounting carrier for the microphone 130, providing a place to mount and secure it. When the microphone 130 is not in use, it can be placed on the frame 310, eliminating the need to find a separate location for it, thus providing convenience for the user.
[0097] In some embodiments, such as Figure 1 As shown, the wearable device 300 also includes a sensor 210 disposed on the frame 310, the sensor 210 being used to detect the distance between the first microphone 130a and the second microphone 130b of the microphone assembly 100.
[0098] In this embodiment, the structure of the wearable device 300 is further defined. Specifically, the wearable device 300 also includes a sensor 210, which is mounted on a frame 310. The frame 310 serves to mount and fix the sensor 210. The sensor 210 is used to detect the distance between the first microphone 130a and the second microphone 130b of the microphone assembly 100. The sensor 210 sends the detected data to the motherboard 320 so that the motherboard 320 can confirm whether the first microphone 130a and the second microphone 130b are independently set or assembled together. If the first microphone 130a and the second microphone 130b are independently set, a noise reduction algorithm is invoked for noise reduction.
[0099] In some embodiments, such as Figure 1As shown, the frame 310 is a glasses frame, which includes a first lens section 330 and a second lens section 340, and the microphone assembly 100 is located between the first lens section 330 and the second lens section 340.
[0100] In this embodiment, the frame 310 is a glasses frame, which includes a first lens portion 330 and a second lens portion 340, and defines the cooperation structure of the microphone assembly 100, the first lens portion 330 and the second lens portion 340 such that the microphone assembly 100 is located between the first lens portion 330 and the second lens portion 340.
[0101] Among them, such as Figure 1 As shown, sensor 210 is disposed on one of the first lens portion 330 and the second lens portion 340. Alternatively, sensor 210 may also be disposed on the temple of the frame.
[0102] Specifically, the wearable device 300 includes a microphone assembly 100, which does not require sound pickup when using the XR (Extended Reality) visual function of the wearable device 300. When the microphone 130 of the microphone assembly 100 is in the first position, the microphone 130 is not electrically connected to the motherboard 320, and the microphone 130 does not acquire sound.
[0103] When the microphone 130 is to be used for sound pickup, it is flipped to the second position and electrically connected to the motherboard 320.
[0104] The microphone assembly 100 includes a first microphone 130a and a second microphone 130b. When receiving audio signals in a relatively quiet environment, one of the first microphone 130a and the second microphone 130b is activated. When the user receives speech in a noisy environment, effective speech acquisition can be achieved by changing the inherent position of the microphone 130 and utilizing the noise reduction algorithm of the wearable device 300.
[0105] When microphone 130 is in the first position, it does not interact with the motherboard 320, thus reducing the power consumption of the wearable device 300. When microphone 130 is in the second position, the conductive part 132 is electrically connected to the connecting part 114. At this time, the circuit board 134 of microphone 130 is electrically connected to the motherboard 320 of wearable device 300. That is to say, when microphone 130 is in the second position, it can acquire sound sources to meet the call usage needs of wearable device 300.
[0106] The circuit board 134 is located in the connecting arm 142 of the microphone 130.
[0107] The wearable device 300 includes a frame and a microphone assembly 100. The microphone assembly 100 includes a rotatable first microphone 130a, a second microphone 130b, and a fixing structure 110. Both the first microphone 130a and the second microphone 130b include a body structure 140 and a connecting arm 142. The body structure 140 is rotatable relative to the fixing structure 110. The body structure 140 has three conductive protrusions 133 of different volumes (e.g., conductive protrusions 133 are metal balls). The fixing structure 110 is electrically connected to the mainboard 320 of the frame.
[0108] The fixed structure 110 has a first side and a second side that are arranged opposite to each other.
[0109] like Figure 4 As shown, the upper half of the first side surface of the fixing structure 110 has three semi-circular grooves of different diameters, arranged in a row. Semi-circular groove A is located on the outermost side, semi-circular groove B is located in the middle side, and semi-circular groove C is located on the innermost side. The lower half of the first side surface of the fixing structure 110 has three semi-circular grooves of different diameters. Semi-circular groove A' is located on the outermost side, semi-circular groove B' is located in the middle side, and semi-circular groove C' is located on the innermost side.
[0110] like Figure 5 As shown, the upper half of the second side surface of the fixing structure 110 has three semi-circular grooves of different diameters, arranged in a row. Semi-circular groove X is located on the outermost side, semi-circular groove Y is located in the middle side, and semi-circular groove Z is located on the innermost side. The lower half of the first side surface of the fixing structure 110 has three semi-circular grooves of different diameters. Semi-circular groove X' is located on the outermost side, semi-circular groove Y' is located in the middle side, and semi-circular groove Z' is located on the innermost side.
[0111] like Figure 4 As shown, the positions of semicircular grooves A', B', and C' are symmetrical to those of semicircular grooves A, B, and C. The difference lies in that each of the semicircular grooves A', B', and C' contains a conductive spring 116, which is connected to the pins of the MCU (Micro Control Unit) on the motherboard 320. The networks corresponding to semicircular grooves A', B', and C' are three-way networks: a microphone 130 power network, a detection signal network, and a ground network. The power network is connected to the motherboard 320 and communicates with the MCU.
[0112] The discs located on the left and right sides of the fixed structure 110 (i.e., the main body structure 140) connect to the connecting arms 142 of the microphone 130, and each connecting arm 142 contains a circuit board 134. The discs on the left and right sides are coaxially fitted with the fixed structure 110 in the middle. The left disc has three metal balls, and the right disc has three metal balls. The metal balls are connected to the power supply, detection signal, and GND on the circuit board 134.
[0113] When microphone 130 is not in use, the two first microphones 130a and second microphone 130b on the left and right sides face upwards. At this time, the three metal balls on the left disk are located in the semi-circular grooves A, B, and C, respectively, and the three metal balls on the right disk are located in the semi-circular grooves X, Y, and Z, respectively. At this time, no power is supplied to the circuit board 134, and microphone 130 is not in working condition.
[0114] When using microphone 130, the user rotates the connecting arm 142 of the first microphone 130a and the second microphone 130b downwards. The three metal balls on the left disk are located in the semi-circular grooves A', B' and C' respectively, and the three metal balls on the right disk are located in the semi-circular grooves X', Y' and Z' respectively. This powers on the circuit board 134 of microphone 130 and it begins to receive audio signals.
[0115] When the ambient noise does not affect the microphone 130's sound pickup, the two microphones 130 are combined into one, and the metal arms of the first microphone 130a and the second microphone 130b on the left and right sides are combined together by the protrusion 200 and the concave part 190. For example... Figure 10 As shown, the magnets inside the microphone 130 are symmetrically distributed. The first microphone 130a has its N-pole 170 facing outwards and its S-pole 180 facing inwards, with the voice coil 360 wound around the N-pole 170. The second microphone 130b has its N-pole 170 facing inwards and its S-pole 180 facing outwards, with the voice coil 360 wound around the S-pole 180. The wearable device 300 can be controlled by acquiring one of these signals as the audio source.
[0116] like Figure 11 As shown, when external noise affects the sound pickup of microphone 130, the first microphone 130a and the second microphone 130b separate, becoming two independent microphones 130. The distance between the connecting arms 142 of the first microphone 130a and the second microphone 130b is d, and the two audio signals can be used for compensation in other algorithms. The two audio signals form a stable phase difference, which, combined with the noise reduction algorithm, achieves the purpose of noise reduction.
[0117] Sensor 210 is used to detect the distance between the first microphone 130a and the second microphone 130b to determine whether the first microphone 130a and the second microphone 130b are separated. If they are separated, a noise reduction algorithm is invoked to reduce noise.
[0118] like Figure 7 As shown, a rotating shaft 150 and a motor are configured in the middle of the fixed structure 110, with the motor's two ends linked to the discs on the left and right sides. When an incoming call or a group battle mode signal is received, the main control chip sends an enable signal to drive the motor and automatically flip the microphone 130 down. Once the microphone 130 reaches the second position and the power and key signals are connected, conversation can begin.
[0119] During a normal call, when the mouth is close to the output port 144 of the first microphone 130a, a relatively large audio signal, Voice1, is generated. The output port 144 of the second microphone 130b also picks up some voice signal Voice1, but it is much smaller than Voice2 (Voice2 is the audio signal picked up by the second microphone 130b). These two signals are input to microphone 130, whose input terminal is a differential amplifier. The differential amplifier subtracts the two signals and then amplifies them to obtain the signal Voice delta, where Voice delta = Voice1 - Voice2. If there is background noise in the usage environment, because the sound source is far away from microphone 130, the intensity of the sound waves reaching microphone 130 is almost the same, meaning Voice1 is approximately equal to Voice2. Thus, for background noise, although both the first microphone 130a and the second microphone 130b pick up audio signals, Voice delta is approximately 0. Therefore, this setting can effectively eliminate environmental noise interference around microphone 130, achieving the purpose of noise reduction.
