Description

Technical Field

[0001] This application relates to the technical field of recording devices, and more particularly to a recording device. Background Technology

[0002] In today's rapidly developing digital information environment, recording devices can be used in audio production studios, news interviews, meeting minutes, personal voice memos, and other scenarios. Recording devices can preserve sound data and are widely used in various fields.

[0003] The recording device has a button to start recording. When the user presses the button, it makes contact with the internal circuit board, triggering the circuit to conduct and initiating recording. A microphone is used to record sound; it is mounted on the circuit board and electrically connected to it. To achieve integration, the microphone and the button are positioned relatively close together.

[0004] However, when the buttons on a recording device are pressed, the contact between the buttons and the circuit board generates vibrations. These vibrations become even more frequent when the buttons are pressed to highlight key areas in the recording. Since the microphone is mounted on the circuit board and close to the buttons, it easily records this vibrational noise, thus reducing the recording quality. Utility Model Content

[0057] In related technologies, recording devices are equipped with a button to activate the recording function. When the user presses the button, it contacts the internal circuit board, triggering the circuit to conduct and activating the recording function. A microphone is used to record sound; the microphone is mounted on the circuit board and electrically connected to it. To achieve integration of the recording device, the distance between the microphone and the button is relatively close.

[0058] However, the recording device has a button to activate the recording function. When the user presses the button, it makes contact with the internal circuit board, triggering the circuit to conduct and activating the recording function. The microphone is used to record sound; it is mounted on the circuit board and electrically connected to it. To achieve integration of the recording device, the microphone and the button are relatively close together.

[0059] However, when the buttons on a recording device are pressed, the contact between the buttons and the circuit board generates vibrations. These vibrations become even more frequent when the buttons are pressed to highlight key areas in the recording. Since the microphone is mounted on the circuit board and close to the buttons, it easily picks up this vibrational noise, reducing the recording quality. Furthermore, the recording device being placed on a table or mounted on other equipment also experiences vibrations, causing the microphone to easily record this vibrational noise, further degrading the recording quality.

[0060] To address the aforementioned problems, this application provides a recording device in which a microphone is electrically connected to a circuit board via a flexible conductive element to achieve signal communication. The flexible conductive element absorbs vibrations, preventing the transmission of vibrational energy from the circuit board to the microphone, thereby avoiding vibrational noise recorded by the microphone and improving the recording quality of the recording device. Furthermore, the microphone is fixed to a first housing, and gaps are provided between the microphone and both the circuit board and the second housing to prevent vibrations transmitted through contact between the microphone and the circuit board, and also to prevent the microphone from receiving vibrations transmitted from the circuit board to the second housing. This design prevents the microphone from recording noise generated by vibrations of the circuit board and the second housing, thus improving the recording quality of the recording device.

[0061] Furthermore, the circuit board is fixed to the second housing, and the microphone is fixed to the first housing. When the second housing is subjected to vibrations such as being struck on a table, these vibrations are transmitted to the circuit board. The gap between the circuit board and the microphone prevents the microphone from being vibrated, thus avoiding the microphone picking up noise caused by the vibration of the second housing and improving the recording quality of the recording device.

[0062] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0063] Combination Figures 1-5 As shown, this application provides a recording device 010. The recording device 010 is used to record sound and convert it into electrical signals. The recording device 010 can also process or store the electrical signals as digital files. For example, the recording device 010 can be configured as a voice recorder, lavalier microphone, or other similar device.

[0064] In some possible implementations, the recording device 010 can be configured as a recording card, which can perform functions such as recording, transcription, translation, and intelligent summarization. The recording card can be magnetically attached to the back of portable devices such as mobile phones, eliminating the need to carry a separate recorder and thus making the recording card portable.

[0065] The recording device 010 includes a housing 100. The housing 100 protects the internal electronic components from damage caused by physical damage, dust, moisture, or other factors.

[0066] Furthermore, the housing 100 includes a first housing 110, which can be configured as the top cover of the recording device 010. A portion of the top cover can be used to mount buttons 400 or a display screen.

[0067] Furthermore, the housing 100 includes a second housing 120, and the first housing 110 and the second housing 120 are connected to form the housing 100.

[0068] For example, the first housing 110 and the second housing 120 can be connected by fasteners such as bolts to ensure the stability of the connection between the first housing 110 and the second housing 120.

[0069] For example, the first housing 110 and the second housing 120 can be bonded together with sealant to improve the sealing of the connection.

[0070] The outer surface of the second housing 120 is used for fixed connection with other devices (such as mobile phones), avoiding the need to carry the recording device 010 alone, and improving the portability of the recording device 010.

[0071] For example, a magnetic element is installed on the inner surface of the second housing 120, and the outer surface of the second housing 120 is made to fit with other devices by means of the magnetic element.

[0072] For example, an adhesive is provided on the outer surface of the second housing 120, and the second housing 120 is attached to other devices by means of the adhesive.

[0073] Alternatively, the outer surface of the second housing 120 may be used to adhere to other objects (such as a desktop) to prevent the recording device 010 from moving.

[0074] The recording device 010 includes a circuit board 200, which integrates functions such as electrical signal processing, power management, and data storage. It can amplify, filter, digitize, and transmit audio signals. The circuit board 200 is housed within the housing 100 to prevent damage from external forces.

[0075] The circuit board 200 can be fixed to the inner surface of the second housing 120 to ensure the stability of the circuit board 200.

[0076] The recording device 010 includes a button 400. The button 400 is movably disposed on the first housing 110. The user uses the button 400 to start or stop the recording function of the recording device 010. The button 400 may also be configured with other functions, which can be designed according to actual needs.

[0077] Combination Figure 4 and Figure 5 As shown, the recording device 010 includes a microphone 320, which is the core sound receiving component of the recording device 010. The microphone 320 can convert sound waves in the air into electrical signals.

[0078] Multiple microphones 320 can be configured according to actual needs. Multiple microphones 320 are positioned near the inner edge of the housing for easy sound pickup.

[0079] Specifically, four microphones 320 are provided. The four microphones 320 can be arranged according to actual needs. For example, the four microphones 320 can be set at the four corners of the recording device 010.

[0080] For example, microphone 320 may be a silicon microphone (Micro Electromechanical System microphone, or MEMS microphone for short). Silicon microphones are based on silicon wafer fabrication processes. When sound waves cause the silicon microphone diaphragm to vibrate, the capacitance of the silicon microphone changes, which is then converted into an electrical signal.

[0081] The microphone 320 is electrically connected to the circuit board 200 via a flexible conductive element to enable signal transmission.

[0082] For example, the flexible conductive element is configured as a flexible circuit board. The microphone 320 is electrically connected to the circuit board 200 via the flexible circuit board. The flexible circuit board can be bent, which reduces the assembly difficulty of connecting the microphone 320 to the circuit board 200 and prevents vibration from being transmitted from the circuit board 200 to the microphone 320.

[0083] For example, the flexible conductive component can be a wire. The microphone 320 can be electrically connected to the circuit board 200 via one or more wires. This wire connection provides high flexibility in the connection between the microphone 320 and the circuit board 200, allowing for configuration as needed. Furthermore, this prevents vibration from being transmitted from the circuit board 200 to the microphone 320.

[0084] Alternatively, the flexible conductive component can be made of conductive fibers. Using conductive fibers ensures a high degree of reliability in the connection between the microphone 320 and the circuit board 200.

[0085] It is easy to understand that the microphone 320 of the recording device 010 is electrically connected to the circuit board 200 via a flexible conductive element to achieve signal communication. The flexible conductive element can absorb vibration, preventing vibration energy from being transmitted from the circuit board 200 to the microphone 320, thereby preventing vibration noise recorded by the microphone 320 and improving the recording quality of the recording device 010. Furthermore, the microphone 320 is fixed to the first housing 110, and gaps are provided between the microphone 320 and the circuit board 200 and the second housing 120, respectively, to prevent vibration transmitted through contact between the microphone 320 and the circuit board 200, and also to prevent the microphone 320 from being subjected to vibration transmitted from the circuit board 200 to the second housing 120. This arrangement prevents the microphone 320 from recording noise generated by the vibration of the circuit board 200 and the second housing 120, thereby improving the recording quality of the recording device 010.

[0086] Furthermore, the circuit board 200 is fixed to the second housing 120, and the microphone 320 is fixed to the first housing 110. When the second housing 120 is subjected to vibrations such as being struck on a table, these vibrations are transmitted to the circuit board 200. The gap between the circuit board and the microphone 320 prevents the microphone 320 from being vibrated, thus avoiding the microphone 320 from picking up noise caused by the vibration of the second housing 120, thereby improving the recording quality of the recording device 010.

[0087] Furthermore, the first housing 110 and the second housing 120 can be made of different materials to meet the different needs of the recording device 010.

[0088] For example, the first housing 110 can be made of glass, which can improve the aesthetics of the recording device 010. The second housing 120 can be made of metal, which can improve the wear resistance of the recording device.

[0089] For example, the first housing 110 can be made of plastic, which can increase the complexity of its design. The second housing 120 can be made of metal, which can improve the wear resistance of the recording device.

[0090] The first housing 110 and the second housing 120 are made of different materials. Vibration is transmitted between the first housing 110 and the second housing 120. Due to the difference in vibration transmission coefficients between the different materials, the energy of the vibration will be attenuated. Therefore, the microphone 320 is fixed to the first housing 110, and the circuit board 200 can be fixed to the inner surface of the second housing 120. This can reduce the vibration energy, thereby reducing the noise recorded by the microphone 320 and improving the recording quality of the recording device 010.

[0091] Furthermore, the housing includes a seal, and the first housing 110 has an opening, with the seal sealingly connected to the opening. The microphone is mounted on the inner surface of the seal. The seal is made of a different material than the first housing 110, which can reduce noise picked up by the microphone 320 and improve the recording quality of the recording device 010.

[0092] The flexible conductive component can be configured as a flexible printed circuit board (FPC) 310, which enables the transmission of electrical signals. Furthermore, the flexible circuit board 310 can absorb vibrations due to its flexibility. For example, the flexible circuit board 310 can be a printed circuit made of a flexible insulating substrate. Some flexible circuit boards 310 can be bent, rolled, or folded to meet various application requirements.

[0093] The flexible circuit board 310 includes a fixing part 311, which is electrically connected to the microphone 320 and transmits the electrical signal of the microphone 320 to the flexible circuit board 310.

[0094] For example, a connector is welded to the fixing part 311, and the fixing part 311 is electrically connected to the microphone 320 through the connector.

[0095] The flexible circuit board 310 includes a connecting part 312, which enables electrical signal transmission between the flexible circuit board 310 and the circuit board 200.

[0096] For example, the connector 312 is soldered with gold fingers, and the connector 312 is electrically connected to the circuit board 200 through the gold fingers.

[0097] For example, the connecting part 312 is provided with copper pads, and the copper pads are electrically connected to the circuit board 200 by a soldering process.

[0098] The flexible circuit board 310 includes a flexible portion 313, with a first end connected to a fixed portion 311 and a second end connected to a connecting portion 312. The flexible portion 313 transmits electrical signals to the connecting portion 312. Furthermore, the flexible portion 313 can absorb vibrations, reducing the transmission of vibrational energy between the circuit board 200 and the microphone 320.

[0099] The fixing part 311 has a first plate surface and a second plate surface facing away from each other. The first plate surface of the fixing part 311 is electrically connected to the microphone 320. It is understood that the first plate surface of the fixing part 311 and the microphone 320 can be physically fixedly connected. For example, the first plate surface of the fixing part 311 is provided with a pin-type interface, which is connected to the microphone 320 through a soldering process. Simultaneously, electrical signals are transmitted between the fixing part 311 and the microphone 320 through the pin-type interface.

[0100] The second plate of the fixing part 311 is fixed to the inner surface of the housing 100 of the recording device 010. For example, the second plate of the fixing part 311 is fixed to the inner surface of the housing 100 by double-sided tape or adhesive.

[0101] The connecting portion 312 of the flexible circuit board 310 is used for electrical connection with the circuit board 200. The flexible circuit board 310 can transmit electrical signals to the circuit board 200 for processing while maintaining the reliability of the electrical connection.

[0102] The microphone 320 is connected to the fixing part 311, allowing electrical signals to be transmitted from the microphone 320 to the fixing part 311. The fixing part 311, the flexible part 313, and the connecting part 312 are connected in sequence, allowing electrical signals to be transmitted from the flexible part 313 to the connecting part 312. The connecting part 312 is connected to the circuit board 200, thereby allowing electrical signals to be transmitted to the circuit board 200 for processing or storage.

[0103] Reference Figure 5 and Figure 6 As shown, the flexible circuit board 310 includes a reinforcing plate 330, which can enhance the mechanical strength and rigidity of the flexible circuit board 310 and is used to support and reinforce the fixing part 311, ensuring the stability of the fixing part 311 and the microphone 320.

[0104] For example, the reinforcing plate 330 can be made of stainless steel to ensure its strength and rigidity.

[0105] For example, the reinforcing plate 330 can be made of fiberglass to ensure the strength and rigidity of the reinforcing plate 330 and to achieve insulation.

[0106] In some possible implementations, the thickness of the reinforcing plate 330 is greater than or equal to 0.1 mm and less than or equal to 0.4 mm. This prevents it from occupying too much space within the housing 100 of the recording device 010, while ensuring the strength and rigidity of the reinforcing plate 330.

[0107] For example, the thickness of the reinforcing plate 330 can be set to a size range of 0.1mm, 0.2mm, 0.3mm, 0.4mm, or any combination of both.

[0108] The fixing part 311 of the flexible circuit board 310 is directly fixed to the housing 100. The fixing part 311 of the flexible circuit board 310 is easy to bend. The fixing part 311 may not fit tightly with the housing 100 due to bending, or the connection between the flexible circuit board 310 and the microphone 320 may be broken.

[0109] Understandably, the first fixing surface of the reinforcing plate 330 is fixedly connected to the second plate surface of the fixing part 311, and the second fixing surface of the reinforcing plate 330 is used to connect with the inner surface of the housing 100. After the fixing part 311 of the flexible circuit board 310 is strengthened by the reinforcing plate 330, the reliability of the connection between the microphone 320 and the flexible circuit board 310 is ensured, and the stability and reliability of the flexible circuit board 310 are ensured.

[0110] For example, the reinforcing plate 330 is made of fiberglass board with a thickness of 0.4 mm. The first fixing surface of the reinforcing plate 330 is adhered and fixed to the second plate surface of the fixing part 311 using double-sided adhesive. The second fixing surface of the reinforcing plate 330 is fixed to the inner surface of the housing 100 using double-sided adhesive.

[0111] Furthermore, the first fixing surface of the reinforcing plate 330 and the second plate surface of the fixing part 311 are connected by a conductive double-sided adhesive.

[0112] Furthermore, the reinforcing plate 330 and the fixing part 311 are connected by a conductive adhesive, which reduces the size of the connection structure and facilitates the integrated design of the recording device 010. For example, the conductive adhesive can be a conductive film to connect the reinforcing plate 330 and the fixing part 311.

[0113] The outer contour of the reinforcing plate 330 matches the outer contour of the partial fixing part 311, which avoids the reinforcing plate 330 occupying too much internal space of the housing 100, thereby improving the space utilization of the recording device 010 and facilitating the integration of the recording device 010.

[0114] Furthermore, the outer contour of the reinforcing plate 330 matches the outer contour of the part of the fixing part 311, which facilitates the installation of the reinforcing plate 330 and the fixing part 311 of the flexible circuit board 310. It is only necessary to align the outer contours of the two.

[0115] The microphone 320 has a connection surface, and the connection surface has connection terminals. The microphone 320 is electrically connected to the flexible circuit board 310 through the connection surface.

[0116] The connecting surface faces the first housing 110 to avoid it facing the second housing 120, which would cause the flexible circuit board 310 to bend, increase its length, and make its installation more difficult. Furthermore, having the connecting surface facing the first housing 110 prevents the reinforcement plate 330 from being placed on the side of the microphone 320 facing the second housing 120, thus avoiding interference between the reinforcement plate 330 and the circuit board 200 and facilitating its installation.

[0117] The first housing 110 is provided with a sound receiving hole 121, which can connect the inside of the housing 100 and the outside of the housing 100, and allows sound waves to enter the inside of the recording device 010.

[0118] In some possible implementations, the opening of the sound receiving hole 121 inside the housing 100 is provided with a waterproof membrane assembly (not shown in the figure) to prevent foreign objects or moisture from entering the interior of the recording device 010 and causing damage to the recording device 010.

[0119] For example, the waterproof membrane assembly includes a waterproof membrane, a sealing gasket, and a pressure ring. The sealing gasket is located between the housing 100 and the waterproof membrane to prevent foreign matter or moisture from entering the housing 100 from between the waterproof membrane and the housing 100.

[0120] The pressure ring is connected to the housing 100 and pressed onto the waterproof membrane to ensure the stability of the connection between the waterproof membrane and the housing 100.

[0121] The microphone 320 is provided with a sound inlet 321, which is used to guide sound waves into the microphone 320 so as to complete the recording of sound.

[0122] The opening orientation of the sound inlet 321 is at a certain angle to the opening orientation of the sound receiver 121. When noise (such as wind noise) blows towards the recording device 010, due to the angular difference between the orientations of the sound inlet 321 and the sound receiver 121, the airflow cannot flow directly into the sound inlet 321 from the sound receiver 121 in a straight line. Some of the noise will be blocked or diverted by the housing 100, thereby suppressing wind noise and improving the audio quality of the recording device.

[0123] For example, the angle between the opening of the sound inlet 321 and the opening of the sound outlet 121 can be set to 0 degrees, 30 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees, 180 degrees, or any combination of both.

[0124] In some possible implementations, refer to Figure 2As shown, the first housing 110 is provided with a sound receiving hole 121, which can connect the inside of the housing 100 and the outside of the housing 100. The sound receiving hole 121 can allow sound waves to enter the inside of the recording device 010. The sound receiving hole 121 is in the same direction as the thickness of the housing 100.

[0125] Combination Figure 2 and Figure 6 As shown, the microphone 320 is provided with a sound inlet 321, which is used to guide sound waves into the microphone 320 to complete sound recording. The opening of the sound inlet 321 faces the same direction as the thickness of the housing 100.

[0126] The fixing part 311 is provided with a first through hole 3111, and the reinforcing plate 330 is provided with a second through hole 331. The sound receiving hole 121, the sound inlet hole 321, the first through hole 3111, and the second through hole 331 are coaxial and connected in sequence. When sound waves are transmitted to the microphone 320 through the sound receiving hole 121 and the sound inlet hole 321 in the air, the loss of sound wave energy during the transmission process can be reduced, thereby improving the sound reception quality of the microphone 320.

[0127] The projection of the microphone 320 toward the flexible circuit board 310 is located within the first surface of the fixing part 311. In other words, the first surface of the fixing part 311 covers the connection surface where the microphone 320 and the fixing part 311 are connected, ensuring full coverage and fit between the flexible circuit board 310 and the microphone 320. This arrangement prevents some connections (such as some pins) of the flexible circuit board 310 from being unconnected to the microphone 320, thereby improving the reliability of the connection between the flexible circuit board 310 and the microphone 320.

[0128] In some possible implementations, combined Figure 7 and Figure 8 As shown, the microphone aperture 121 is perpendicular to the thickness direction of the housing 100. The opening of the microphone inlet 321 faces the same direction as the thickness direction of the housing 100. This prevents impurities from entering the microphone 320 and causing damage to it.

[0129] It is easy to understand that the outer surface of the recording device 010, which is perpendicular to the thickness direction of the housing 100, can be used to fit against other devices or apparatuses for mounting or placing the recording device 010. The microphone hole 121 is located on the outer periphery of the housing 100, and the opening of the microphone hole 121 is perpendicular to the thickness direction of the housing 100. This prevents the microphone hole 121 from being blocked when the recording device 010 is placed, thereby preventing sound wave loss during transmission and improving recording quality.

[0130] The microphone hole 121 and the housing 100 can be manufactured using a one-piece molding technique. The shape and diameter of the microphone hole 121 can be set according to the requirements of the recording device 010.

[0131] Furthermore, in order to enhance the sound pickup effect of the microphone 320, the microphone 320 is positioned near the sound pickup hole 121.

[0132] As explained above, the reinforcing plate 330 fixes the fixing part 311 of the flexible circuit board 310 to the inner surface of the housing 100 to improve the stability of the flexible circuit board 310 and the microphone 320.

[0133] Combination Figure 6 and Figure 8 As shown, the reinforcing plate 330 is provided with a first notch 332, the opening direction of the first notch 332 facing the sound receiving hole 121. The first notch 332 can avoid obstructing the propagation path of sound waves (from the sound receiving hole 121 to the sound inlet hole 321), thereby avoiding the loss of sound wave energy and improving the sound reception quality.

[0134] Similarly, the fixing part 311 is provided with a second notch 3112, the opening direction of the second notch 3112 is towards the sound receiving hole 121, the second notch 3112 can avoid obstructing the propagation path of the sound wave (from the sound receiving hole 121 to the sound receiving hole 321), thereby avoiding the loss of sound wave energy and improving the sound reception quality.

[0135] Aligning the opening contour of the second notch 3112 with the opening contour of the first notch 332 facilitates the connection between the reinforcing plate 330 and the fixing part 311 of the flexible circuit board 310. Furthermore, this arrangement improves the aesthetics of the recording device 010.

[0136] The fixing part 311 of the flexible circuit board 310 is fixed to the inner surface of the first housing 110, and the opening of the sound inlet 321 faces the fixing part 311. If the opening of the sound inlet 321 of the microphone 320 is away from the fixing part 311, the plane of the microphone 320 that is away from the opening of the sound inlet 321 is connected to the first housing 110 through the fixing part 311 and the reinforcing plate 330. The opening of the sound inlet 321 and the opening of the sound receiving hole 121 are set in the same plane, which facilitates the improvement of the sound receiving effect of the sound receiving hole 121. The sound receiving hole 121 of the housing 100 needs to be set away from the first housing 110, which increases the thickness of the housing 100 and cannot meet the integration requirements of the recording device 010.

[0137] In some possible implementations, the circuit board 200 is provided with a clearance area 210. The clearance area 210 is used to avoid direct contact between the circuit board 200 and the microphone 320, thereby preventing vibrations of the circuit board 200 from being transmitted to the microphone 320. In addition, the clearance area 210 causes the microphone 320 to occupy part of the empty space on the circuit board 200, thereby improving the integration of the recording device 010.

[0138] Specifically, the gap between the sidewall of the clearance area 210 and the microphone 320 is greater than or equal to 0.1mm. This prevents the circuit board 200 from making direct contact with the microphone 320, thereby cutting off the transmission path of vibrations generated by the circuit board 200 to the microphone 320. This helps to ensure the clarity and stability of the microphone 320's sound pickup and improves the audio recording quality of the recording equipment.

[0139] The gap between the side wall of the clearance area 210 and the microphone 320 is less than or equal to 2mm, which can improve the integration of the recording device 010.

[0140] For example, the gap between the side wall of the clearance area 210 and the microphone 320 can be set to a size range of 0.1mm, 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.0mm or any combination of both.

[0141] In some possible implementations, the microphone aperture 121 communicates with the clearance area 210, and the microphone 320 is located within the clearance area 210. When sound enters the recording device 010 from the microphone aperture 121, the sound is transmitted from the clearance area 210 to the microphone 320, which can prevent the circuit board 200 from blocking the transmission of sound, resulting in unclear recorded sound.

[0142] The microphone 320 has a microphone bottom surface 322, which faces away from the opening of the sound inlet 321. A gap is provided between the microphone bottom surface 322 and the inner surface of the second housing 120. The second housing 120 is fixedly connected to other devices and is affected by vibrations from those devices. By ensuring that the microphone bottom surface 322 does not directly contact the second housing 120, vibrations can be prevented from being transmitted to the microphone 320, thus preventing the microphone 320 from being loosely fixed or recording vibration noise.

[0143] A gap is provided between the bottom surface 322 of the microphone and the inner surface of the second housing 120. This facilitates the assembly of the microphone 320 and avoids interference between the microphone 320 and the second housing 120.

[0144] The larger the gap between the bottom surface 322 of the microphone and the inner surface of the second housing 120, the lower the energy of the vibration noise, which can reduce the noise recorded by the microphone 320.

[0145] Furthermore, the gap between the bottom surface 322 of the microphone and the inner surface of the second housing 120 is greater than or equal to 0.1 mm to prevent the microphone 320 from being loosely fixed or recording vibration noise.

[0146] Furthermore, the gap between the bottom surface 322 of the microphone and the inner surface of the second housing 120 is less than or equal to 2 mm, which can improve the integration of the recording device 010.

[0147] For example, the size of the gap between the bottom surface 322 of the microphone and the inner surface of the second housing 120 can be set to 0.1mm, 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.0mm or any combination of both.

[0148] Combination Figure 2 and Figure 7 As shown, a switch 220 is also provided on the circuit board 200. The switch 220 is used to connect or disconnect the module on the circuit board 200 that can realize the recording function, so that the recording device can start or stop recording.

[0149] Button 400 can move toward switch 220 to trigger switch 220. It is understood that switch 220 is located in the movement path of button 400, causing button 400 to move toward switch 220 until button 400 abuts against switch 220. Continuing to move button 400 can press the switching part of switch 220 to control the opening and closing of the recording device.

[0150] The recording device also includes a sound-insulating component 500, which is connected to the circuit board 200 and covers the switch component 220. The sound-insulating component can be a diaphragm. When the button 400 is moved, the button 400 can first come into contact with the sound-insulating component 500. The sound-insulating component 500 can be used to block the sound emitted when the switch component 220 is triggered, thereby reducing the impact of noise on microphone pickup.
