[0036] The present application provides a pickup. The present application also provides a pickup system comprising the pickup.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The pickup, also known as the monitoring head. The monitoring pickup is a device used to collect the ambient sound on site and transmit it to the back-end equipment. It is composed of a microphone and an audio amplifier circuit. The pickup is generally divided into digital pickup and analog pickup. The digital pickup is a sound sensor device that converts the analog audio signal into a digital signal through a digital signal processing system and performs corresponding digital signal processing.

[0039] like Figures 1 to 8As shown, an embodiment of the present application provides a microphone, which is installed on a device to be detected 17 to detect the device. For example, in transportation scenarios such as coal, thermal power, and ports, the belt conveyor is affected by material impact and abnormal parts, and the resulting failure will seriously affect the entire production process and even cause safety accidents. The microphone can effectively detect faults such as belt conveyor deviation, wear, and roller abnormality in advance, and improve the safety performance of the equipment when working in the above scenario. The microphone mainly includes a shell 1, a first waterproof part 3, and a second waterproof part 4. A microphone 2 is arranged on the wall of the shell 1; the first waterproof part 3 is arranged on the side of the microphone 2 away from the inner cavity of the shell 1; and the second waterproof part 4 is arranged between the microphone 2 and the wall of the shell 1. Specifically, when the microphone provided with the above two waterproof parts is working, the first waterproof part 3 and the second waterproof part 4 can both prevent water from entering the interior of the microphone from the position of the microphone 2. Such a setting can improve the waterproof performance of the microphone. Moreover, when the first waterproof member 3 located on the outside or the second waterproof member 4 located on the microphone 2 and the wall of the housing 1 is damaged after the microphone is used for a long time, the other waterproof member can also play a waterproof role.

[0040] Exemplarily, the first waterproof component 3 is a sheet-shaped waterproof component to prevent water from entering the microphone 2; and the second waterproof component 4 is a sealing ring, which is arranged between the wall of the pickup and the microphone 2. Specifically, the second waterproof component 4 is arranged on the circumferential outer side of the microphone 2 to prevent water from entering the pickup through the gap between the microphone 2 and the wall.

[0041] The pickup of the above structure has a first waterproof member 3 disposed on the side of the microphone 2 away from the inner cavity of the housing 1, and a second waterproof member 4 disposed between the microphone 2 and the wall of the housing 1. The first waterproof member 3 and the second waterproof member 4 can achieve a waterproof effect, play a role in protecting the pickup, and improve the accuracy of the pickup detection structure. Moreover, the pickup is provided with two waterproof members, which can achieve a double waterproof effect. When one of the waterproof members is damaged, the other waterproof member can also achieve a waterproof effect, further improving the waterproof performance of the pickup.

[0042] In some embodiments, the pickup includes a cover 5 and a first seal 6, the cover 5 is connected to the housing 1, and the first seal 6 is disposed between the housing 1 and the cover 5. The housing 1 and the cover 5 form a receiving cavity, and the housing 1 and the cover 5 increase the receiving space for the main structure of the pickup.

[0043] Further, an annular groove 101 is provided on at least one of the shell 1 and the cover 5, and the first seal 6 is a grooved annular structure adapted to the annular groove 101 provided on the shell. Specifically, taking the annular groove 101 provided on the shell 1 and the first seal 6 being a grooved annular structure adapted to the annular groove 101 as an example, when the shell 1 and the cover 5 need to be assembled together, the annular groove wall of the grooved annular structure is inserted into the groove of the annular groove 101, and at the same time, the groove wall of the annular groove 101 is also inserted into the groove of the grooved annular structure, so that the first seal 6 can be quickly installed and pre-installed on the shell 1 to realize the pre-installation of the shell 1 and the first seal 6. After that, the shell 1 and the cover 5 are connected together, and the connected shell 1 and the cover 5 will press against the first seal 6 to realize the seal between the shell 1 and the cover 5.

[0044] Another optional implementation is also provided in this embodiment. An annular groove 101 is opened on the cover body 5, and the first seal 6 is a groove-shaped annular portion adapted to the annular groove 101. In this way, the first seal 6 can also be quickly installed and pre-installed on the housing 1.

[0045] Another optional implementation is also provided in this embodiment, in which a first annular groove is opened on the shell 1, and a second annular groove is also opened on the cover body 5, and the first seal 6 is a groove-shaped annular structure adapted to the above two annular grooves. When the first seal 6 is installed between the shell 1 and the cover body 5, the installation efficiency of the shell 1 and the cover body 5 can be further improved, and the displacement of the first seal 6 can be further avoided.

[0046] Exemplarily, the cross-sectional shape of the first sealing member 6 may be U-shaped, F-shaped, V-shaped, C-shaped, W-shaped, N-shaped, M-shaped, etc.

[0047] In some embodiments, the microphone further includes an elastic support member 7 disposed between the first waterproof member 3 and the microphone 2. Exemplarily, the first waterproof member 3 is generally a waterproof breathable membrane disposed on the surface of the microphone 2. The waterproof breathable membrane is disposed on the surface of the microphone 2. The waterproof breathable membrane may be wrinkled, which affects its waterproof and breathable performance. By disposing the elastic support member 7 between the first waterproof member 3 and the microphone 2, the first waterproof member 3 can be supported, thereby improving the waterproof performance of the first waterproof member 3.

[0048] In some embodiments, the pickup further includes a magnet 8 connected to the cover 5 and / or the housing 1, and the magnet 8 is magnetically connected to the device to be detected 17. Exemplarily, the magnet 8 is connected to the cover 5, and specifically, a magnet bracket 15 for mounting the magnet 8 is provided on the cover 5, and the pickup is magnetically connected to the device to be detected 17 through the magnet 8 to achieve connection between the pickup and the device to be detected 17. Here, by providing the magnet 8, the magnetic attraction performance of the magnet 8 can facilitate connection with the device to be detected 17, thereby improving connection efficiency.

[0049] Another optional implementation is also provided in this embodiment. The magnet 8 can also be arranged on the shell 1, preferably on the side wall surface of the shell 1.

[0050] Another optional implementation is also provided in this embodiment, in which multiple magnets 8 are provided, some of the magnets 8 are provided on the cover 5, and the rest of the magnets 8 are provided on the shell 1. Such an arrangement can improve the stability of the connection between the magnet 8 and the device to be detected 17.

[0051] In addition, when the microphone is located in a scene with large vibration, it can be connected to the device to be detected 17 by passing bolts through the bracket mounting hole 14, which can meet the needs of different scenes such as wall mounting, clamp mounting, and hoisting.

[0052] In some embodiments, the pickup also includes a magnetic shielding member 9 disposed between the mainboard 16 of the pickup and the magnet 8. Exemplarily, when the magnet 8 is disposed on the cover 5 and / or the housing 1, and the pickup is installed with the device to be detected 17 through the magnet 8, in a magnetic installation environment, the strong magnetic field environment has a relatively large impact on the stability of the electrical performance of the device. In order to avoid magnetic field interference, a magnetic shielding member 9 is disposed between the mainboard 16 of the pickup and the magnet 8, wherein the magnetic shielding member 9 can be a soft magnetic material, a magnetic alloy, a magnetic ceramic, etc. With such a configuration, the magnetic shielding member 9 can effectively isolate the radiation effect of the magnetic field on the mainboard 16, thereby protecting the mainboard.

[0053] In some embodiments, the pickup includes a mainboard 16 disposed in the inner cavity of the housing 1, and a heat-conducting buffer 10 is disposed between the mainboard 16 and the housing 1, and / or a heat-conducting buffer 10 is disposed between the mainboard 16 and the cover 5. Specifically, since the housing 1 and the cover 5 are provided with a support structure for fixing the mainboard 16, and the mainboard 16 is provided with electronic components such as a main chip and a capacitor, by providing a heat-conducting buffer 10 between the mainboard 16 and the housing 1, and / or providing a heat-conducting buffer 10 between the mainboard 16 and the cover 5, the main structure can be protected. Moreover, the buffer 10 is a heat-conducting buffer 10, so that the buffer 10 can quickly remove the heat generated by the mainboard 16 during operation, and can improve the heat dissipation performance of the mainboard 16.

[0054] In some embodiments, multiple pickups are provided, and each pickup is provided with at least two electrical connection ports 11, and multiple pickups can be electrically connected in sequence through connecting wires. Specifically, since the detection distance of a single pickup is limited, when the detection distance is long, by connecting the power supply port and the switch at one end, multiple pickups are connected in sequence through connecting wires, so that multiple devices can be connected in series, which can be applied to scenarios with different detection lengths, thereby improving the applicability of the pickups.

[0055] In some embodiments, the pickup further includes a microphone holder 12, which is detachably connected to the housing 1, and the microphone 2 is disposed on the microphone holder 12. Specifically, the microphone 2 is mounted on the microphone holder 12, and then the microphone holder 12 is mounted on the housing 1, so that the microphone 2 can be assembled conveniently and the assembly efficiency can be improved.

[0056] Furthermore, a second sealing member 13 is provided between the microphone 2 and the microphone holder 12. This arrangement can improve the stability of the connection between the microphone 2 and the microphone holder 12 and prevent the microphone 2 from shaking; and when water enters the position where the microphone 2 is located, it can prevent water from entering the position of the main board 16 located in the inner cavity of the housing 1, thereby protecting the main board 16.

[0057] In some embodiments, the first waterproof component 3 is a waterproof and breathable membrane. Exemplarily, the waterproof and breathable membrane can be a polyurethane film, a polyester film, a PTEE film or a TPU film, etc. Such a configuration enables the first waterproof component 3 to have a waterproof function while allowing gas to pass through without affecting the sound reception of the microphone 2, thereby ensuring the normal use of the microphone 2.

[0058] In addition, the second waterproof member 4 is set as an annular sealing ring. Specifically, this can improve the sealing performance between the microphone 2 and the wall of the housing 1. When the waterproof breathable membrane is worn out after long-term use, the annular sealing ring can also play a waterproof effect to prevent water from entering the housing 1 and damaging the mainboard 16.

[0059] A pickup system includes a pickup. Since the pickup system includes the pickup, the beneficial effects of the pickup system brought by the pickup can be found in the above content and will not be described in detail here.
