[0038] In order to further understand the content of the present application, the present application will be described in detail in combination with the drawings and examples. Example 1

[0039] As Figures 1-2As shown, the utility model provides a kind of intercom, including shell assembly 100, gland assembly 200 and control assembly 300.Shell assembly 100 includes the shell 120 with inner cavity 110, and the end surface of shell 120 is equipped with first recess 121.Gland assembly 200 is connected in first recess 121.Control assembly 300 includes trigger switch 310, and the button of trigger switch 310 is directly opposite the center of gland, and gland moves to the direction of the inner cavity 110 after being pressed, contacts and starts trigger switch 310.

[0040] In the intercom of the application, control assembly 300 is used to control the start of intercom.When the button on trigger switch 310 is pressed, call signal can be sent, and the called party can start conversation after response.Trigger switch 310 is directly opposite gland assembly 200, and gland assembly 200 is arranged in the first recess 121 on the end surface of shell 120.Because the area of the end surface of shell 120 is large, the area of gland can be set relatively large, facilitating pressing operation.Gland assembly 200 includes first cover plate 210 and second cover plate 220 detachably connected on first cover plate 210.First cover plate 210 is used to connect gland assembly 200 on shell 120, and second cover plate 220 is used for finger pressing.Because first cover plate 210 and second cover plate 220 are detachably connected, when first cover plate 210 wears, only first cover plate 210 needs to be replaced, without replacing the whole intercom, providing service life of intercom. Embodiment 2

[0041] As Figures 3-4 As shown, to facilitate the movement of first cover plate 210 to the direction of inner cavity 110, first cover plate 210 is connected to the bottom of first recess 121.Specifically, first recess 121 bottom is equipped with circular bottom plate 122, and the outer ring of circular bottom plate 122 is fixedly connected with the side wall of first recess 121.Circular bottom plate 122 is centrally provided with first through hole 123, and the diameter of first through hole 123 is larger than the outer diameter of first cover plate 210.First cover plate 210 is concentrically connected to the inner side of first through hole 123.The annular gap 230 between the inner wall of first through hole 123 and the outer ring of first cover plate 210 is formed.The at least one bridge 240 is arranged on the gap 230 between the inner wall of first through hole 123 and the outer ring of first cover plate 210.

[0042] When the first cover plate 210 is subjected to pressure, the bridge 240 can produce local deformation, allowing the first cover plate 210 to move toward the inner cavity 110. Because the first cover plate 210 is connected to the housing 120 in the first groove 121 via the bridge 240, the connection area between the two is relatively small, making it easier for the bridge 240 to deform and bend, thereby using less pressing force to drive the entire first cover plate 210 toward the inner cavity 110. This reduces the difficulty of pressing and the speed of wear on the cover plate, thereby increasing the service life of the cover plate. In addition, due to the reduced pressing force, the hardness of the entire first cover plate 210 can be increased, thereby increasing its service life.

[0043] An annular ring 250 may be sleeved in the gap 230. The annular ring 250 has a protruding portion 251. The protruding portion 251 is adapted to the size and number of the gap 230 and is just filled into the gap 230. The annular ring 250 can fill the gap 230 and play a certain waterproof role. Example 3

[0044] like Figure 4 As shown, in order to optimize the pressure transmission of the gland assembly 200, this embodiment provides a pressure column 211 extending toward the inner cavity 110 at the center of the first cover plate 210. The pressure column 211 has a threaded hole 212. A threaded column 221 is provided at the center of the second cover plate 220. The threaded column 221 is threadedly connected to the threaded hole 212 provided at the center of the first cover plate 210. The bottom of the pressure column 211 faces the trigger switch 310. When the second cover plate 220 is subjected to force, the pressure is transferred to the threaded column 221 on the first cover plate 210 through the threaded column 221 provided at its center. When the first cover plate 210 is subjected to force, the bridge 240 is deformed, causing the first cover plate 210 to move toward the inner cavity 110 as a whole. The bottom end of the pressure column 211 contacts the trigger switch 310, thereby activating the intercom. The pressure column 211 and the threaded column 221 cooperate to improve the structural strength of the gland assembly 200 at this point, preventing the gland from cracking due to long-term use. Example 4

[0045] like Figure 4 As shown, to enhance the aesthetics of the intercom, in this embodiment, a pattern is drawn on the second cover plate 220. Specifically, a coating 260 is provided on the surface of the second cover plate 220, and a pattern is sprayed onto the coating 260 using printing technology. For example, by using UV printing technology, the coating 260 can be applied to the surface of the second cover plate 220 to form a user-specified pattern or photo, making the intercom more in line with customer needs and improving the overall aesthetics of the intercom. Alternatively, a pattern can be applied to the outer surface of the second cover plate 220 by affixing stickers. Example 5

[0046] like Figures 3-5As shown, the shell 120 includes an upper shell 124 and a lower shell 125, which are combined to form the inner cavity 110.

[0047] The shell 120 is provided with a second through hole 126 and a third through hole 127 on the outer periphery, which are oppositely arranged on both sides of the shell 120 and are both in communication with the inner cavity 110. The second through hole 126 is connected with the "+" volume button 310, and the third through hole 127 is connected with the "-" volume button 320. The volume of the intercom can be adjusted by pressing the "+" volume button or the "-" volume button 320. The "+" volume button 310 and the "-" volume button 320 can be easily operated on both sides of the intercom, avoiding mispressing on the same side.

[0048] The shell 120 is further provided with a fourth through hole 128 on the outer periphery, which is a circular hole and is located on the same side as the third through hole 127. The fourth through hole 128 is connected with the power switch button 330, which is used to control the on-off of the intercom.

[0049] The shell 120 is provided with a slot hole 129 on the outer periphery. The slot hole 129 is provided with a communication or power interface, which is generally a type-c interface. The slot hole 129, the second through hole 126 and the third through hole 127 are distributed in the shape of an isosceles triangle, which is convenient for holding and operating the intercom even when connecting the power line or communication line. The slot hole 129 is covered with a dust plug 130 which can open and close the slot hole 129. Specifically, the bottom end of the dust plug 130 is fixed to one end of the slot hole by a rubber column. When the interface needs to be used, the dust plug 130 is taken out of the slot hole 129, and when it is not needed, the dust plug 130 is closed. In order to facilitate the opening of the dust plug 130, an arc-shaped groove is provided on one side of the dust plug 130, and the fingernail can be inserted into the arc-shaped groove to take out the dust plug 130 from the slot hole 129.

[0050] The shell 120 is further provided with a fifth through hole on the outer periphery, which is opposite to the slot hole 129, and the microphone is placed at the fifth through hole.

[0051] The shell 120 is provided with a plurality of sixth through holes on the outer periphery, which are located on the side of the fifth through hole, and the sixth through holes are opposite to the loudspeaker.

[0052] The lower shell 125 is provided with a seventh through hole on the shell 120, which is located at the edge of the lower shell 125 and is parallel to the direction of the shell 120, so that the seventh through hole is integrally connected with a support block. The seventh through hole can be used to connect the hanging rope 560. Embodiment 6

[0053] As Figure 5As shown, the control assembly 300 includes a control panel fixed in the inner cavity 110. A trigger switch 310 is provided on the control panel opposite the pressure column 211. The control assembly 300 includes a "+" volume button 310, a "-" volume button 320, a microphone, and a loudspeaker. The "+" volume button 310, the "-" volume button 320, the microphone, and the loudspeaker are electrically connected to the outer periphery of the control panel, and the control panel centrally controls the activation and deactivation of the functions of each control assembly 300.

[0054] The control assembly 300 includes at least one antenna 340, which is mounted vertically on the control panel. Preferably, there are four antennas 340, each mounted vertically on the control panel, with its end facing the end face of the housing 120. The antennas 340 are embedded within the inner cavity 110, making them more concealed and enhancing the aesthetics of the intercom. Furthermore, the antennas 340 are fixed vertically to the control panel, with their ends facing the end face of the housing 120. This provides support when the housing 120 is subjected to significant deformation, thereby enhancing its stability.

[0055] The battery assembly includes a battery module, which is connected to the control panel surface and supplies power to the control module. The battery module is fixed to the side of the control panel facing the lower shell 125. Example 7

[0056] like Figure 2 As shown, to facilitate secure portability of the intercom, a first magnetic member 400 is secured to the inner surface of the housing 120 facing away from the gland assembly 200. The first magnetic member 400 is a magnet or sheet metal. The first magnetic member 400 secures the intercom to an external magnetic device. During use, the intercom only needs to be secured to the external magnetic device. When the intercom is needed, it can be quickly and easily removed from the external magnet. Example 8

[0057] like Figures 6-9 As shown, this embodiment provides the external magnet device described in Example 7. A magnetic suction cup 500 has a built-in second magnetic component 510 and is easy to carry. When in use, the end face of the intercom housing 120 is fixed to the magnetic suction cup 500 by magnetic attraction. The magnetic suction cup 500 includes a magnetic panel 520 and a magnetic back plate 530. The outer diameters of the magnetic panel 520 and the magnetic back plate 530 are the same, and the concave surfaces of the two are arranged relative to each other so that an annular groove 550 is formed between the two. The second magnetic component 510 is clamped and fixed between the magnetic panel 520 and the magnetic back plate 530.

[0058] The outer periphery of the magnetic back plate 530 is arc-shaped, and the fixed plate 540 is fixedly connected to the end surface of the concave surface.

[0059] The fixed plate 540 comprises a curved plate 541, which is securely attached to the back plate. A cylinder 542 is perpendicularly connected to the other side of the curved plate 541. Hooks 543 are provided on the circumference of the cylinder 542, facing outward. A first cross-shaped support 544 is vertically fixed to the center of the fixed plate 540. Both ends of the first support 544 are connected to circular second supports 545.

[0060] The second magnetic member 510 is located on the first pillar 544 and the second pillar 545 .

[0061] The center of the convex surface of the magnetic panel 520 is flat, and the outer periphery is curved. A first ring 521 and a second ring 522 are vertically fixed to the end surface of the concave surface of the magnetic panel 520. The first ring 521 and the second ring 522 are arranged coaxially. The first ring 521 and the second ring 522 are separated by a hook hole 523 corresponding in number and position to the hook 543. The hook 543 is connected to the hook hole 523 to fix the magnetic panel 520 and the magnetic back plate 530. A support column 524 is provided at the center of the concave surface of the magnetic panel 520. The support column 524 is used to fix the second magnetic component 510.

[0062] The magnetic front panel 520 and magnetic back panel 530 are connected by hooks 543. Once connected, an annular groove 550 formed on their outer circumference not only reduces the weight of the magnetic components but also enhances their aesthetics. Furthermore, a lanyard 560 passes through the annular groove 550 and connects to a lanyard hole 546 on the outer circumference of the fixed plate 540. When in use, the lanyard 560 can be worn directly around the neck for easy carrying. Example 9

[0063] like Figures 10-12 As shown, for ease of portability, the present invention provides a walkie-talkie buckle 600. The buckle 600 includes a rectangular connecting plate 610, with at least two claws 620 integrally connected to the outer edge of the connecting plate 610. Preferably, four claws 620 are connected to the outer edge of the connecting plate 610, and the four claws 620 are eccentrically arranged. The eccentric arrangement of the claws 620 enables the claws 620 to be precisely engaged with the four corners of the walkie-talkie without interfering with the use of the peripheral buttons of the walkie-talkie. The claw 620 includes a claw arm 621 and a claw finger 622 connected perpendicularly or approximately perpendicularly to the claw arm.

[0064] The outer end of the top of the claw finger 622 is set as a first curved surface 6221, and the inner end is set as a curved inward-concave surface 6222. The first curved surface 6221 can better fit the outer periphery of the intercom, which is not only more beautiful but also makes the grip more comfortable. The curved inward-concave surface 6222 can better hold the intercom tightly to prevent it from falling off the buckle 600. A recessed groove 6223 is provided on the inner side of the claw finger 622, and a soft pad 630 is filled and fixed in the recessed groove 6223. The inside of the soft pad 630 is in direct contact with the outer periphery of the intercom to prevent the claw 620 from scratching the surface of the intercom.

[0065] The intercom buckle 600 comprises a resilient clamping piece 640, one end of which is fixed on the connecting plate 610, and the other end is suspended and provided with a clamping tooth 641.
