Description

Technical Field

[0001] This application relates to the field of sound pickup equipment technology, and in particular to a sound pickup device and a hat. Background Technology

[0002] In scenarios such as firefighting and rescue, voice recording is an essential measure during the operation. Of course, voice recording is also typically required in other scenarios (such as games based on virtual reality technology).

[0003] Currently, in the aforementioned scenarios, firefighters and rescue personnel typically need to wear numerous pieces of equipment, such as fire / rescue gear, fire extinguishers, and fire helmets. If they are further burdened with additional microphones for voice recording, it undoubtedly increases their workload and makes it difficult to guarantee the quality of the microphone's pickup. Therefore, improving the microphone's pickup quality while minimizing the wearer's burden has become an urgent problem to solve. Utility Model Content

[0004] The main technical problem addressed by this application is to provide a sound pickup device and a hat that can improve the sound pickup quality of the wearer while minimizing the burden on the wearer.

[0005] To address the aforementioned technical problems, the first aspect of this application provides a sound pickup device, including a circuit board, a housing, and a connector. The circuit board is provided with a plurality of microphones arranged in an array. The housing includes a first housing and a second housing, which together form an accommodating space. The circuit board is mounted in the accommodating space. A sound pickup hole is provided on the first end face of the first housing at a position corresponding to the microphone. The connector includes a mounting part and a connecting part. The mounting part is connected to the housing, and the connecting part protrudes from the second end face of the second housing, which is opposite to the first end face. The connecting part is used for detachable connection with the front edge of a hat body.

[0006] Therefore, the sound pickup device includes a circuit board, a housing, and a connector. The circuit board has multiple microphones arranged in an array. The housing includes a first housing and a second housing, which together form an accommodating space. The circuit board is mounted in the accommodating space. The first end face of the first housing has a sound pickup hole at a position corresponding to the microphone. The connector includes a mounting part and a connecting part. The mounting part is connected to the housing, and the connecting part protrudes from the second end face of the second housing, which is opposite to the first end face. The connecting part is used for detachable connection to the front edge of the hat body. Since the mounting part of the connector is connected to the housing, and the connecting part is detachably connected to the front edge of the hat body, when sound pickup is needed, the sound pickup device can be connected simply by connecting the connecting part of the connector to the front edge of the hat body. The microphone is mounted on the hat body and can be detached from the hat body simply by separating it from the front edge of the hat body via the connector when not in use. This eliminates the need for the wearer to wear it on other parts of their body, improving the flexibility of assembly and disassembly and reducing the wearer's burden. Furthermore, since the circuit board is installed in the space formed by the first and second housings, the first end face of the first housing has a microphone hole at the corresponding position, and the connector protrudes from the second end face of the second housing, which is opposite to the first end face. Therefore, when the connector is connected to the front edge of the hat body, the first end face with the microphone hole faces the wearer's speaking space, improving the microphone's sound pickup quality. Thus, the microphone's sound pickup quality is improved while minimizing the wearer's burden.

[0007] The first housing, the second housing, and the circuit board are all arc-shaped.

[0008] Therefore, the first shell, the second shell, and the circuit board are all arc-shaped. Since the sound pickup device is detachably connected to the front edge of the hat body through the connecting part of its connector, it can fit the wearer's forehead as closely as possible in shape.

[0009] In this device, at least the first housing and the second housing are provided with extensions of the same shape at the same position on the inner arc, in a direction away from the outer arc. The pickup device also includes an external battery that is mechanically connected to the second housing and electrically connected to the circuit board, and the external battery is carried on the extension of the second housing.

[0010] Therefore, at least the first housing and the second housing are provided with extensions of the same shape at the same position on the inner arc, in a direction away from the outer arc. The pickup device also includes an external battery that is mechanically connected to the second housing and electrically connected to the circuit board. The external battery is carried on the extension of the second housing, that is, the external battery can be carried on the extension on the inner side of the arc, which helps to improve the connection reliability of the external battery.

[0011] The outer casing end face that contacts the second end face of the external battery has the same shape as the extension of the second casing.

[0012] Therefore, since the outer casing end face that contacts the second end face has the same shape as the extension of the second casing, the outer casing can be supported on the extension of the second casing as stably as possible.

[0013] The first housing, the second housing, and the circuit board all have extensions at the same position on the inner arc.

[0014] Therefore, in addition to the first and second housings, the circuit board also has an extension at the same position on the inner arc, thus expanding the area on the circuit board that supports the arrangement of electronic components.

[0015] The circuit board has multiple microphones arranged at equal intervals along the chord direction.

[0016] Therefore, the multiple microphones on the circuit board are arranged at equal intervals along the string direction, which can form a regular sound pickup range in the wearer's speaking space, helping to provide as many convenient conditions as possible for subsequent speech processing.

[0017] The mounting parts of each connector are respectively located at different positions on the inner arc of the first housing.

[0018] Therefore, since the mounting parts of each connector are respectively provided at different positions on the inner arc of the first shell, the connecting parts of each connector can be detachably connected to the front edge of the hat body, which helps to improve the connection reliability between the pickup device and the hat body.

[0019] The microphone also includes an external battery. The circuit board has a voice processing circuit, a wireless transmission circuit, a charging circuit, and a first interface. The voice processing circuit is electrically connected between the microphone and the wireless transmission circuit. The external battery, the charging circuit, and the first interface are electrically connected in sequence. The external battery is also electrically connected to the voice processing circuit and the wireless transmission circuit.

[0020] Therefore, the sound pickup device also includes an external battery. The circuit board is equipped with a voice processing circuit, a wireless transmission circuit, a charging circuit, and a first interface. The voice processing circuit is electrically connected between the microphone and the wireless transmission circuit. The external battery, the charging circuit, and the first interface are electrically connected in sequence. The external battery is also electrically connected to the voice processing circuit and the wireless transmission circuit. Therefore, the wireless transmission circuit can wirelessly transmit the voice data output by the voice processing circuit.

[0021] The voice processing circuit is also electrically connected to the first interface to read voice data from the first interface.

[0022] Therefore, since the voice processing circuit is also electrically connected to the first interface, it is possible to read the voice data output by the voice processing circuit through the first interface.

[0023] The wireless transmitting circuit is used to communicate with the wireless receiving circuit of the receiving device, and the receiving device also includes a second interface electrically connected to the wireless receiving circuit to read voice data through the second interface.

[0024] Therefore, since the wireless transmitting circuit is used to communicate with the wireless receiving circuit of the receiving device, and the receiving device also includes a second interface electrically connected to the wireless receiving circuit for reading voice data through the second interface, it can support external devices to read voice data by plugging in the second interface.

[0025] To address the aforementioned technical problems, a second aspect of this application provides a hat, including a sound pickup device as described in the first aspect, and a hat body, the hat body including a front edge portion, and a connecting portion on the connector of the sound pickup device being detachably connected to the front edge portion.

[0026] Therefore, the hat includes the aforementioned pickup device and the hat body. The hat body includes a front edge portion, and the connecting part of the pickup device's connector is detachably connected to the front edge portion. On the one hand, since the mounting part of the connector is connected to the housing, and the connecting part is used to detachably connect to the front edge portion of the hat body, when pickup is needed, the pickup device can be installed on the hat body simply by connecting the connecting part of the connector to the front edge portion of the hat body. When pickup is not needed, the pickup device can be detached from the hat body simply by separating the connecting part of the connector from the front edge portion of the hat body. Therefore, the wearer does not need to wear it on other parts of the body, which can improve the flexibility of the pickup device's installation and removal and help to reduce the wearer's burden as much as possible. On the other hand, since the circuit board is installed in the accommodating space formed by the first housing and the second housing, the first end face of the first housing has a pickup hole at the position corresponding to the microphone, and the connecting part of the connector protrudes from the second end face of the second housing, which is opposite to the first end face. Therefore, when the connecting part is connected to the front edge portion of the hat body, the first end face with the pickup hole can face the wearer's speaking space, which helps to improve the pickup quality of the pickup device for the wearer. Therefore, it is possible to improve the sound pickup quality of the microphone while minimizing the burden on the wearer. Attached Figure Description

[0032] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0033] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0034] In this paper, the terms "system" and "network" are often used interchangeably. The term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "many" in this paper means two or more.

[0035] Please see Figure 1 , Figure 1 This is an exploded view of an embodiment of the sound pickup device of this application. The sound pickup device 10 includes a circuit board 11, a housing 12, and a connector 13. The circuit board 11 is provided with a plurality of microphones 111 arranged in an array. The housing 12 includes a first housing 121 and a second housing 122, which enclose a receiving space (not shown). The circuit board 11 is mounted in the receiving space. The first end face 1211 of the first housing 121 has a sound pickup hole 1212 at a position corresponding to the microphone 111. The connector 13 includes a mounting part 131 and a connecting part 132. The mounting part 131 is connected to the housing 12. The connecting part 132 protrudes from the second end face 1221 of the second housing 122, which is opposite to the first end face 1211. The connecting part 132 is used for detachable connection with the front edge (not shown) of a hat body (not shown). It should be noted that the front edge of the hat body can specifically include the position of the hat body corresponding to the wearer's forehead, the area near the forehead (such as the temples), etc. when the hat body is worn normally.

[0036] In one implementation scenario, the number of microphones 111 arrayed on the circuit board 11 can be 2, 3, 4, etc., and the specific number of microphones 111 is not limited here.

[0037] In one implementation scenario, the surface of the pickup hole 1212 may be covered with a wind noise shield to reduce the noise signal picked up by the microphone 111.

[0038] In one implementation scenario, the first housing 121, the second housing 122, and the circuit board 11 can all be arc-shaped. It should be noted that in practical applications, the curvature at each position of the arc can preferably be set based on the curvature of the front edge of the hat body at each position. The specific values ​​of the curvature at each position of the arc are not limited here, nor will they be listed individually. For example, taking the microphone 10 configured on a fire helmet, the curvature of the arc at each position can be determined based on the curvature of the fire helmet at each position of the front edge. Other cases can be deduced similarly, and will not be elaborated further here. In the above method, the first housing 121, the second housing 122, and the circuit board 11 are all arc-shaped. Since the microphone 10 is detachably connected to the front edge of the hat body through the connecting part 132 of its connector 13, it can fit the wearer's forehead as closely as possible in shape.

[0039] In one implementation scenario, taking the first housing 121, the second housing 122, and the circuit board 11 as examples where they are all arc-shaped, at least the first housing 121 and the second housing 122 can both have an extension A1 of the same shape at the same position on the inner arc, moving away from the outer arc. The pickup device 10 also includes an external battery 14 that is mechanically connected to the second housing 122 and electrically connected to the circuit board 11, and the external battery 14 is supported on the extension A1 of the second housing 122. It should be noted that the inner arc and the outer arc are two arcs of the arc, and the inner arc is closer to the center of the arc than the outer arc. In the above-described manner, at least the first housing 121 and the second housing 122 are provided with an extension A1 of the same shape at the same position on the inner arc, in a direction away from the outer arc. The pickup device 10 also includes an external battery 14 that is mechanically connected to the second housing 122 and electrically connected to the circuit board 11. The external battery 14 is carried on the extension A1 of the second housing 122, that is, the external battery 14 can be carried on the extension A1 on the inner side of the arc, which helps to improve the connection reliability of the external battery 14.

[0040] In a specific implementation scenario, please refer to the relevant documents. Figure 1 Both the first housing 121 and the second housing 122 may have an extension A1 located at the middle position of the inner arc, moving away from the outer arc. Of course, the above example is only one possible example position of the extension A1 in the first housing 121 and the second housing 122, and other possible positions are not limited here.

[0041] In a specific implementation scenario, please refer to the following: Figure 1The extension A1 can be set into a trapezoidal shape, with its width narrowing towards the inner arc. Of course, the above example is merely one possible shape for the extension A1; other possible shapes will not be listed here. Furthermore, although the extension A1 can be set into different shapes depending on the actual scenario, the edge of the extension A1 furthest from the inner arc should still ideally fit as closely as possible to the wearer's forehead. For details, please refer to the aforementioned description of the curvature of the arc at various locations; further elaboration will not be repeated here.

[0042] In a specific implementation scenario, the first housing 121 and the second housing 122 can be connected by screws, adhesive, interference fit, or other methods to form an enclosure space. Correspondingly, the external battery 14 can also be mechanically connected by screws, adhesive, or other methods. Here, the connection method between the first housing 121 and the second housing 122, and the connection method between the external battery 14 and the housing 12, are not limited. For illustrative examples, please refer to the following... Figure 1 The first housing 121 may be provided with a stud B1, and the external battery 14 may be provided with a stud B2. Correspondingly, the second housing 122 may be provided with a through hole B3, and the circuit board 11 may also be provided with a through hole B4. Screws (not shown) can pass through stud B2, through hole B3, through hole B4, and stud B1 in sequence, so as to tightly lock the external battery 14, the second housing 122, the circuit board 11, and the first housing 121 by engaging with the internal threads of studs B1 and B2. Of course, the above example is only one possible example of how the first housing 121, the second housing 122, the circuit board 11, and the external battery 14 can be tightly connected in actual applications. Other possible connection methods are not limited here, nor will they be listed one by one.

[0043] In a specific implementation scenario, the outer casing end face 141 of the external battery 14 that contacts the second end face 1221 can have the same shape as the extension A1 of the second housing 122. In this manner, since the outer casing end face 141 of the external battery 14 that contacts the second end face 1221 has the same shape as the extension A1 of the second housing 122, the external battery 14 can be supported as stably as possible on the extension A1 of the second housing 122.

[0044] In a specific implementation scenario, not only can the first housing 121 and the second housing 122 both have extensions A1 of the same shape at the same position on the inner arc, moving away from the outer arc, but the circuit board 11 can also have an extension A2 at the same position on the inner arc, just like the two mentioned above. It should be noted that the arrangement of the extension A2 can be found in the description of the extension A1 mentioned above, and will not be repeated here. In the above method, in addition to the first housing 121 and the second housing 122, the circuit board 11 also has an extension A2 at the same position on the inner arc, thus expanding the area on the circuit board 11 that supports the arrangement of electronic components.

[0045] In a specific implementation scenario, the external battery 14 may include a casing (not shown), a battery cell (not shown), and a power management circuit (not shown). The battery cell and power management circuit can be housed within the casing. The battery cell can be used to store electrical energy, and the power management circuit can be used to manage the battery cell (e.g., charge / discharge management). Of course, the above example is merely one possible illustration of the external battery 14, and the specific structure of the external battery 14 is not limited here (e.g., the external battery 14 may not include a power management circuit, or the power management circuit may be integrated into the circuit board 11), nor will further examples be provided.

[0046] In one implementation scenario, please refer to the following: Figure 2 , Figure 2 This is a schematic diagram of the structure of a circuit board according to an embodiment of this application. Figure 2 As shown, the circuit board 11 can be configured in an arc shape, and multiple microphones 111 on the circuit board 11 can be positioned in the chord direction (e.g., Figure 2 As shown by the bold dashed line C, the microphones 111 are arranged at equal intervals, meaning that the distance between adjacent microphones 111 in the chord direction is always D. It should be noted that the specific value of the distance D between adjacent microphones 111 in the chord direction is not limited here; it can be set according to the specific dimensions of the circuit board 11. For example, still using... Figure 2 For example, the distance D between adjacent microphones 111 in the string direction can be set to 63.94 mm, the distance between the first left microphone 111 and the second left microphone 111 in the perpendicular direction of the string direction can be set to 55.91 mm, and the perpendicular distance from the second left microphone 111 to the tangent of the outer arc of the circuit board 11 can be set to 8.51 mm. Of course, the above numerical examples are only one possible example in practical applications, and other possible scenarios will not be listed here. In this manner, multiple microphones 111 on the circuit board 11 are arranged at equal intervals in the string direction, forming a regular pickup range in the wearer's speaking space, which helps to provide as many convenient conditions as possible for subsequent speech processing.

[0047] In one implementation scenario, please continue to refer to [the relevant documentation]. Figure 1The mounting portions 131 of each connector 13 can be respectively located at different positions on the inner arc of the first housing 121. For example, the pickup device 10 may include two connectors 13, with the mounting portion 131 of one connector 13 located at one end of the inner arc of the first housing 121, and the mounting portion 131 of the other connector 13 located at the other end of the inner arc of the first housing 121. Of course, the above example is only one possible arrangement when the pickup device 10 includes multiple connectors 13 in practical applications. Other possible arrangements are not limited here, nor will they be listed one by one.

[0048] In one implementation scenario, as a possible example, the connecting portion 132 of the connector 13 can be an adhesive portion (e.g., Velcro, adhesive, etc.) to achieve a detachable connection with the front edge of the hat body; or, as another possible example, the connecting portion 132 of the connector 13 can be a magnetic portion to achieve a detachable connection with a magnetic attachment on the front edge of the hat body; or, as yet another possible example, the connecting portion 132 of the connector 13 can be a snap-fit ​​portion (e.g., a male buckle) to achieve a detachable connection with a snap-fit ​​attachment (e.g., a female buckle) on the front edge of the hat body; or, as yet another possible example, the connecting portion 132 of the connector 13 can be a hook-shaped portion to achieve a detachable connection with a liner on the front edge of the hat body (e.g., the hook-shaped portion can be hooked onto the liner). Of course, the above examples are only a few possible examples of how the connecting portion 132 of the connector 13 can achieve a detachable connection with the front edge of the hat body. Other possible implementation methods are not limited here, nor will they be listed one by one.

[0049] In one implementation scenario, please refer to the following: Figure 3 , Figure 3 This is a circuit diagram of an embodiment of the pickup device of this application. Figure 3As shown, the microphone 10 also includes an external battery 14, and the circuit board 11 is provided with a voice processing circuit 112, a wireless transmission circuit 113, a charging circuit 114, and a first interface 115. The voice processing circuit 112 is electrically connected between the microphone 111 and the wireless transmission circuit 113. The external battery 14, the charging circuit 114, and the first interface 115 are sequentially and electrically connected. The external battery 14 is also electrically connected to the voice processing circuit 112 and the wireless transmission circuit 113 to provide power to both circuits. In the above-described manner, the microphone 10 also includes an external battery 14. The circuit board 11 is provided with a voice processing circuit 112, a wireless transmission circuit 113, a charging circuit 114, and a first interface 115. The voice processing circuit 112 is electrically connected between the microphone 111 and the wireless transmission circuit 113. The external battery 14, the charging circuit 114, and the first interface 115 are electrically connected in sequence. The external battery 14 is also electrically connected to the voice processing circuit 112 and the wireless transmission circuit 113. Therefore, the wireless transmission circuit 113 can wirelessly transmit the voice data output by the voice processing circuit.

[0050] In a specific implementation scenario, the voice processing circuit 112 may include, but is not limited to, an analog-to-digital converter (ADC), a digital signal processor (DSP), etc. The specific structure of the voice processing circuit 112 is not limited here; for details, please refer to the circuit details of voice processing, which will not be elaborated further here. It should be noted that the voice processing circuit 112 and the wireless transmission circuit 113 can communicate via bus protocols such as IIS. The bus protocol used for communication between the voice processing circuit 112 and the wireless transmission circuit 113 is not limited here, nor will it be listed individually.

[0051] In a specific implementation scenario, the wireless transmission circuit 113 may include, but is not limited to, a signal transmission module, a transmission antenna (e.g., a 2.4G band antenna), etc. The specific structure of the wireless transmission circuit 113 is not limited here. For details, please refer to the circuit details of wireless transmission.

[0052] In a specific implementation scenario, the charging circuit 114 may include, but is not limited to, a boost circuit, a buck circuit, etc. The specific structure of the charging circuit 114 is not limited here; for details, please refer to the technical details of the charging technology, which will not be elaborated here. It should be noted that the first interface 115 can also be connected to an external power source to charge the external battery 14 through the current direction of the first interface 115, the charging circuit 114, and the external battery 14.

[0053] In a specific implementation scenario, the first interface 115 may include, but is not limited to, a universal serial bus interface, etc. The specific type of the first interface 115 is not limited here. In addition, the first interface 115 may be set perpendicular to the circuit board 11 (e.g., it may be set perpendicularly to the edge of the extension A2 of the circuit board 11), or the first interface 115 may be set parallel to the circuit board 11. The setting position and setting direction of the first interface 115 are not limited here, and will not be listed one by one.

[0054] In a specific implementation scenario, the wireless transmitting circuit 113 is used for communication connection with the wireless receiving circuit 113' of the receiving device 11', and the receiving device 11' also includes a second interface 115' (e.g., a Universal Serial Bus interface) electrically connected to the wireless receiving circuit 113' for reading voice data via the second interface 115'. In this manner, since the wireless transmitting circuit 113 is used for communication connection with the wireless receiving circuit 113' of the receiving device 11', and the receiving device 11' also includes a second interface 115' electrically connected to the wireless receiving circuit 113' for reading voice data via the second interface 115' (e.g., via UAC output, i.e., USBAudio Class Output), it can support external devices to read voice data by plugging into the second interface 115'. It should be noted that the specific structure of the wireless receiving circuit 113' can be found in the relevant description of the wireless transmitting circuit 113, and it may include a signal receiving module (not shown), a receiving antenna (not shown, such as a 2.4G band antenna), etc., which will not be elaborated here.

[0055] In a specific implementation scenario, the voice processing circuit 112 is also electrically connected to the first interface 115 to read voice data (e.g., via UAC output) through the first interface 115. In this manner, since the voice processing circuit 112 is also electrically connected to the first interface 115, the voice data output by the voice processing circuit 112 can be read through the first interface 115.

[0056] In the above scheme, the sound pickup device 10 includes a circuit board 11, a housing 12, and a connector 13. The circuit board 11 is provided with multiple microphones 111 arranged in an array. The housing 12 includes a first housing 121 and a second housing 122, which together form an accommodating space. The circuit board 11 is installed in the accommodating space. The first end face 1211 of the first housing 121 has a sound pickup hole 1212 at a position corresponding to the microphone 111. The connector 13 includes a mounting part 131 and a connecting part 132. The mounting part 131 is connected to the housing 12, and the connecting part 132 protrudes from the second end face 1221 of the second housing 122, which is opposite to the first end face 1211. The connecting part 132 is used for detachable connection to the front edge of the hat body. On the one hand, since the mounting part 131 of the connector 13 is connected to the housing 12, and the connecting part 132 is used for detachable connection to the front edge of the hat body, when sound pickup is needed, it is only necessary to connect the connector 132 of the connector 13 to the hat body. The microphone 10 can be installed on the hat body by connecting the front edge of the connector 13. When microphones are not needed, the microphone 10 can be detached from the hat body by separating it from the front edge of the hat body through the connecting part 132 of the connector 13. Therefore, the wearer does not need to wear it on other parts of the body, which can improve the flexibility of the microphone 10 and help to reduce the burden on the wearer. On the other hand, since the circuit board 11 is installed in the accommodating space formed by the first housing 121 and the second housing 122, the first end face 1211 of the first housing 121 has a microphone hole 1212 at the position corresponding to the microphone 111, and the connecting part 132 of the connector 13 protrudes from the second end face 1221 of the second housing 122 which is opposite to the first end face 1211. Therefore, when the connecting part 132 is connected to the front edge of the hat body, the first end face 1211 with the microphone hole 1212 can face the wearer's speaking space, which helps to improve the microphone quality of the microphone 10 to the wearer. Therefore, it is possible to improve the sound pickup quality of the pickup device 10 for the wearer while minimizing the burden on the wearer.

[0057] Please refer to the following: Figure 4a and Figure 4b , Figure 4a This is a structural schematic diagram of an embodiment of the hat in this application. Figure 4b This is a structural schematic diagram of another embodiment of the hat in this application. (See attached diagram.) Figure 4a and Figure 4bAs shown, the hat 20 may include the pickup device 10 as described in the above-described pickup device embodiment, and a hat body 21. The hat body 21 may include a front edge portion 211, and the connecting portion 132 on the connector 13 of the pickup device 10 is detachably connected to the front edge portion 211. As a possible example, the hat body 21 may have a liner 212 at the front edge portion 211, and the connecting portion 132 may be configured as a hook-shaped portion, so that it can be hooked onto the liner 212, thereby achieving a detachable connection between the connecting portion 132 and the front edge portion 211. Of course, the above example is only one possible example of achieving a detachable connection. The specific way in which the connecting portion 132 and the front edge portion 211 achieve a detachable connection can be found in the relevant descriptions in the aforementioned disclosed embodiments, and will not be repeated here. It should be noted that the specific type of hat 20 may include, but is not limited to, fire helmets, safety helmets, virtual reality helmets, etc. The specific type of hat 20 is not limited here, nor will it be listed in detail.

[0058] In the above-described scheme, the hat 20 includes the pickup device 10 as described in the above-described pickup device embodiment and the hat body 21. The hat body 21 includes a front edge portion 211, and the connecting portion 132 on the connector 13 of the pickup device 10 is detachably connected to the front edge portion 211. This is because the mounting portion 131 of the connector 13 is connected to the housing 12, and the connecting portion 132 is detachably connected to the front edge portion 211 of the hat body 21. That is, when pickup is needed, the pickup device 10 can be installed on the hat body 21 simply by connecting the connecting portion 132 of the connector 13 to the front edge portion 211 of the hat body 21; and when pickup is not needed, the pickup device 10 can be detached from the hat body 21 simply by separating the connecting portion 132 of the connector 13 from the front edge portion 211 of the hat body 21. Therefore, the wearer does not need to wear additional parts on other parts of the body, which improves the flexibility of assembling and disassembling the microphone 10 and helps to reduce the burden on the wearer. On the other hand, since the circuit board 11 is installed in the accommodating space formed by the first housing 121 and the second housing 122, the first end face 1211 of the first housing 121 has a pickup hole 1212 at the position corresponding to the microphone 111, and the connecting part 132 of the connector 13 protrudes from the second end face 1221 of the second housing 122 which is opposite to the first end face 1211. Therefore, when the connecting part 132 is connected to the front edge 211 of the hat body 21, the first end face 1211 with the pickup hole 1212 can face the wearer's speaking space, which helps to improve the pickup quality of the microphone 10 to the wearer. Therefore, the pickup quality of the microphone 10 to the wearer can be improved while minimizing the burden on the wearer.
