The housing 10 forms a housing space 101, and a clamping member 20 is provided on the side wall of the housing 10. The clamping member 20 includes two connecting parts 202 connected to the side wall of the housing 10. A bending part 201 connected to the connecting part 202 is formed on the side of the clamping member 20 away from the side wall of the housing 10. The clamping member 20 and the housing space 101 are located on opposite sides of the side wall of the housing 10. The housing 10 is provided with a first sound guide channel 301 that penetrates the side wall of the housing 10. The first sound guide channel 301 is arranged adjacent to the clamping member 20 and is arranged corresponding to the bending part 201. The broadcasting device 40 is arranged in the housing space 101 and is arranged corresponding to the first sound guide channel 301. Among them, the first sound guide channel 301 can be set to any reasonable value such as 2 or 3, and can be arranged adjacent to the clamping member 20. It can be set according to needs, and this application does not make specific restrictions here.

[0025] In an optional embodiment, a housing space 101 is formed on the housing 10, the broadcasting device 40 is arranged in the housing space 101, and a first sound guide channel 301 is opened on the housing 10. The first sound guide channel 301 is arranged opposite to the broadcasting device 40, that is, the sound transmitted by the broadcasting device 40 is transmitted through the first sound guide channel 301. By arranging a clamping member 20 at a position adjacent to the first sound guide channel 301, the clamping member 20 is provided with two connecting parts 202, the connecting part 202 is connected to one side end surface of the housing 10, and a bending part 201 is formed on the side of the clamping member 20 away from the side wall of the housing 10. When the sound transmitted by the broadcasting device 40 is transmitted through the first sound guide channel 301, the sound can be gathered together after being reflected by the connecting part 202 and the bending part 201, thereby increasing the volume of the sound. Specifically, a first sound guiding channel 301 is provided through the shell 10, and the sound transmitted by the broadcasting device 40 can be transmitted through the first sound guiding channel 301. A clip 20 is provided on a side surface of the shell 10 away from the accommodating space 101, and the clip 20 is provided adjacent to the first sound guiding channel 301. After the sound is transmitted through the first sound guiding channel 301, the sound will be transmitted to the connecting portion 202 and the bending portion 201, and the connecting portion 202 and the bending portion 201 will reflect the sound, thereby increasing the volume of the sound.

[0026] In this embodiment, two first sound guide channels 301 are provided as an example, that is, two first sound guide channels 301 are provided through the housing 10, the two first sound guide channels 301 are provided in parallel with each other, and can be respectively provided in contact with the two connecting portions 202, the broadcasting device 40 corresponds to the first sound guide channels 301, and the sound of the broadcasting device 40 can be transmitted through the two first sound guide channels 301. A clamping member 20 is provided at adjacent positions of the two first sound guide channels 301, and the bending portion 201 on the clamping member 20 is provided corresponding to the two first sound guide channels 301, that is, two bending portions 201 corresponding to the two first sound guide channels 301 are provided on the clamping member 20, and the two bending portions 201 are provided opposite to each other. After the sound is transmitted through the two first sound guide channels 301, the sound will be transmitted to the two connecting portions 202 and the bending portion 201, so that the sound reflection is gathered between the two bending portions 201, thereby increasing the volume of the sound. In other embodiments, the two bending portions 201 may be arranged away from each other, and the two first sound guiding channels 301 are also arranged corresponding to the bending portions 201 and are arranged adjacent to the connector 20. After the sound passes through the two first sound guiding channels 301 and is reflected by the two bending portions 201 arranged away from each other, the sound can be gathered to both sides, thereby increasing the volume of the sound.

[0027] In a specific application scenario, the smart terminal is set in an intercom, that is, when the user uses the intercom, the broadcasting device 40 of the intercom transmits sound, and the sound is transmitted through the first sound guide channel 301 set through the housing 10. After the sound is transmitted, it is reflected by the connecting part 202 and the bending part 201 on the clamping part 20, so that the sound is gathered and the sound volume heard by the user is increased. The application of intercom in extreme weather is effectively improved.

[0028] In the above embodiment, a clip 20 is provided at a position adjacent to the first sound guide channel 301 on the shell 10, and a bending portion 201 connected to the connecting portion 202 is formed on the side of the clip 20 away from the side wall of the shell 10. After the sound transmitted by the broadcasting device 40 is transmitted through the first sound guide channel 301, the sound will be transmitted to the connecting portion 202 and the bending portion 201, so that the sound is reflected on the bending portion 201, and the reflected sound will be gathered, thereby increasing the volume of the sound.

[0029] In an optional embodiment, the connecting portion 202 extends along one side end surface of the housing 10 toward the bending portion 201, and is connected to the housing 10 and the bending portion 201 to form a guide groove 203. That is, the connecting portion 202 is provided on the clamping member 20, and two connecting portions 202 are provided, and the connecting portion 202 is provided parallel and adjacent to the first sound guide channel 301, so that after the sound of the broadcasting device 40 is transmitted through the first sound guide channel 301, it will be transmitted to the connecting portion 202, and the connecting portion 202 will reflect the sound, and the bending portion 201 is provided at one end of the connecting portion 202 away from the housing 10, and the sound is reflected through the connecting portion 202 and reflected through the bending portion 201, so that the sound is reflected and gathered together to increase the volume of the sound. Specifically, the connecting portion 202 extends along the end surface of one end of the shell 10 toward the bending portion 201, and a groove-shaped guide groove 203 is formed between the bending portion 201, the connecting portion 202 and the shell 10, thereby forming a reflection arc, and the sound is reflected through the reflection arc. In this embodiment, the clamping member 20 also includes a vertical plate 60, and the vertical plate 60 is connected to the connecting portion 202. That is, the clamping member 20 includes two connecting portions 202 and two bending portions 201 connected to the two connecting portions 202, and the two connecting portions 202 are connected through the vertical plate 60, wherein the bending portion 201 may also be provided on the vertical plate 60, so as to reflect the sound, and this application does not make specific limitations here. In other embodiments, the vertical plate 60 may not be provided between the two connecting portions 202.

[0030] In a specific application scenario, the smart terminal is set in the intercom. Obviously, in order to facilitate carrying and taking the intercom, a back clip or other clamps that are convenient for fixing on clothes and pants need to be set on the intercom, that is, a groove-shaped guide groove 203 is formed between the bending portion 201, the connecting portion 202 and the housing 10, and the clamp can be inserted into the guide groove 203, so as to facilitate carrying the intercom. When the docking machine needs to be used, it is not necessary to remove the clamp and the intercom at the same time, and it is only necessary to remove the intercom from the clamp. At this time, the clamp is separated from the guide groove 203, that is, the guide groove 203 is formed to facilitate the insertion of the clamp. Among them, other fixings can also be set on the clamp. When the clamp is inserted in the guide groove 203, the clamp and the intercom are fixed and placed. When the docking machine needs to be removed, the fixing is opened to remove the docking machine.

[0031] In an optional embodiment, if Figure 1 As shown, the connection between the connecting portion 202 and the bending portion 201 is set to an arc structure. That is, after the sound is transmitted through the first sound guide channel 301 by the broadcasting device 40, the sound will be reflected by the bending portion 201 of the arc structure, so as to reduce the consumption of the sound during reflection, for example, after the sound is reflected, it conflicts with the sound transmitted from the first sound guide channel 301. The connection between the connecting portion 202 and the bending portion 201 is set to an arc structure. Specifically, the connection between the connecting portion 202 and the bending portion 201 near the first sound guide channel 301 is set to an arc shape. After the sound is transmitted, it is reflected through the arc structure between the bending portion 201 and the connecting portion 202, so as to gather and increase the volume of the sound. Similarly, the side of the connection between the bending portion 201 and the connecting portion 202 away from the first sound guide channel 301 is also formed into an arc structure.

[0032] In an optional embodiment, the housing 10 is provided with a second sound guide channel 302 that runs through the side wall of the housing 10, and the second sound guide channel 302 is arranged adjacent to the connecting portion 202 away from the bending portion 201. The first sound guide channel is arranged adjacent to the connecting portion 202. Therefore, the sound transmitted by the broadcasting device 40 can be transmitted through the first sound guide channel 301 and the second sound guide channel 302, and the sound transmitted through the first sound guide channel 301 is reflected by the bending portion 201 to increase the volume of the sound. And the second sound guide channel 302 is arranged on the side of the housing 10 away from the bending portion 201, and is arranged adjacent to the connecting portion 202. After the sound is transmitted through the second sound guide channel 302, since the side of the connection between the bending portion 201 and the connecting portion 202 away from the first sound guide channel 301 is also formed into an arc structure, the sound will also be reflected through the connecting portion 202, thereby gathering the sound to the side to increase the volume of the sound. In other embodiments, the two bending portions 201 are arranged away from each other. In this case, the first sound guiding channel 301 is arranged away from the bending portion 201 and adjacent to the connecting portion 202, and the second sound guiding channel 302 is arranged corresponding to the bending portion 201. After the broadcasting device 40 is transmitted through the first sound guiding channel 301 and the second sound guiding channel 302, the sound transmitted from the broadcasting device 40 is transmitted through the second sound guiding channel 302, and the sound is reflected and gathered together through the bending portion 201. The sound transmitted through the first sound guiding channel 301 is gathered to both sides through the arc structure of the connecting portion 202, thereby increasing the volume of the sound.

[0033] In an optional embodiment, the bending portion 201 is parallel to the plane where the end face of the shell 10 is located or is arranged at an angle of no more than 30 degrees, that is, the angle between the bending portion 201 and the plane where the end face of the shell 10 is located can be set to any value between 0°-30°. The positive projection of the bending portion 201 is located on the first sound guide channel 301. Therefore, when the sound of the broadcasting device 40 is transmitted through the first sound guide channel 301, the sound will be directly transmitted to the bending portion 201, so that the sound reflection is gathered in the middle to increase the volume of the sound. Further, the shell 10 is provided with a main sound channel 501 and an auxiliary sound channel 502, the main sound channel 501 is arranged between the two connecting portions 202, and the auxiliary sound channel 502 is arranged on the side of the two connecting portions 202 away from the main sound channel 501. That is, the sound of the broadcasting device 40 can be transmitted through the main sound channel 501, the auxiliary sound channel 502, the first sound guide channel 301 and the second sound guide channel 302. That is, after the sound is transmitted from the broadcasting device 40, the sound is transmitted from the main channel 501. After the sound transmitted by the broadcasting device 40 is transmitted through the first sound guide channel 301, it will be reflected by the connecting portion 202 and the bending portion 201, so that the reflected sound is gathered with the sound transmitted from the main channel 501, thereby effectively increasing the volume of the sound. Similarly, the sound will be transmitted through the auxiliary channel 502. After the sound transmitted by the broadcasting device 40 is transmitted through the second sound guide channel 302, it will be reflected by the arc structure on the connecting portion 202, thereby reflecting the sound to both sides and gathering the sound transmitted from the auxiliary channel 502, thereby increasing the volume of the sound. That is, the main channel 501, the auxiliary channel 502, combined with the first sound guide channel 301 and the second sound guide channel, can effectively improve the degree of sound aggregation, thereby increasing the volume of the sound in one direction.

[0034] In the above manner, the present application sets a clamping member 20 at a position adjacent to the first sound guide channel 301 on the housing 10, and forms a bending portion 201 on the side of the clamping member 20 away from the side wall of the housing 10, so that the sound is reflected on the bending portion 201, and the reflected sound is gathered, thereby increasing the volume of the sound. By setting two ways of connecting with the bending portion 201 on the end face of one side of the housing 10, a groove shape is formed between the bending portion 201, the connecting portion 202 and the housing 10, thereby forming a reflection arc, and the sound is reflected by the reflection arc. By setting the connection between the connecting portion 202 and the bending portion 201 as an arc structure, it is possible to prevent the sound from conflicting with the sound transmitted from the first sound guide channel 301 after reflection, so that the sound transmission is unclear. By opening a second sound guide channel 302 away from the bending portion 201 and adjacent to the connecting portion 202 on the housing 10, the sound transmitted from the second sound guide channel 302 is reflected through the connecting portion 202, thereby gathering the sound to the side to increase the volume of the sound. By setting the main sound channel 501 and the auxiliary sound channel 502 on the shell 10, the sounds transmitted from the first sound guiding channel 301 and the second sound guiding channel 302 can be effectively gathered with the sounds transmitted from the main sound channel 501 and the auxiliary sound channel 502, respectively, so as to increase the volume of the sound.

[0035] The present application also provides a communication device, which includes: a smart terminal and a back clip (not shown), the smart terminal is a smart terminal of any one of the above embodiments, such as Figure 4 As shown, a support member 70 is provided at one end of the back clip, and the support member 70 is movably connected to the bending portion 201. In this embodiment, the support member 70 is clamped to the clamping member 20, and the support member 70 is limited by the bending portion 201, so as to prevent the back clip from being separated from the clamping member 20. By clamping the support member 70 to the clamping member 20, when the user puts the communication device on the user's clothes or other positions, the back clip can be used to clamp the communication device. When the communication device needs to be used, the back clip can be opened to separate the communication device from the user's clothes.

[0036] In an optional embodiment, if Figure 4As shown, the support member 70 is also provided with a slide rail 80, which is provided at both ends of the support member 70, adapted to the bending portion 201, and slidably connected in the guide groove 203. A through hole 801 is provided on the slide rail 80, and the through hole 801 is communicated with the first sound guide channel 301. That is, the slide rail 80 is provided on the support member 70, and when the support member 70 is clamped to the clamping member 20, the slide rail 80 can slide on the bending portion 201, so that the support member 70 is clamped to the clamping member 20, thereby fixing the back clip. And a through hole 801 is provided between the slide rails 80, and is communicated with the first sound guide channel 301, so that the slide rail 80 will not block the first sound guide channel 301, thereby preventing the sound transmitted from the first sound guide channel 301 from being blocked by the slide rail 80. That is, when the broadcasting device 40 transmits sound through the first sound guide channel 301, the sound can be reflected on the bending portion 201 and the connecting portion 202, and the reflected sound can be transmitted through the through hole 801 on the slide rail 80, thereby gathering with the sound transmitted from the main sound channel 501 to increase the volume of the sound.

[0037] In an optional embodiment, if Figure 4 As shown, the slide rail 80 can be connected to the support member 70 through a bracket 701, that is, the slide rail 80 is connected through the bracket 701, and a gap is formed between the slide rail 80 and the support member 70. On the one hand, when the sound is transmitted through the first sound guide channel 301, the end face of the support member 70 is prevented from blocking the sound. On the other hand, the support member 70 can be easily connected to the clamping member 20. Among them, the slide rail 80 extends to both ends in a direction perpendicular to the direction in which the slide rail 80 is slidably inserted in the guide groove 203, that is, the slide rail 80 forms a protruding structure relative to the bracket 701, so that when the slide rail 80 is slidably connected to the inside of the guide groove 203, the support member 70 is clamped in the inside of the guide groove 203 through the protruding structure, and both ends of the slide rail 80 are protrudingly arranged, when the bending portions 201 are relatively arranged or separated, it is convenient to slide and fix the bending portions 201 on the corresponding clamping members 20, and the through hole 801 can be opened on the protruding structure, so that the sound can be transmitted through the through hole 801, and through holes can also be opened at both ends of the slide rail 80, and the present application does not make specific restrictions here.

[0038] Furthermore, the support member 70 is provided with a buckle (not shown) located between the slide rails 80. The housing 10 is provided with a snap interface 503 located between the two connecting portions 202, and the snap interface 503 is adapted to the buckle. That is, when the support member 70 is snapped onto the snap connector 20, the buckle can be connected to the snap interface 503 on the housing 10, thereby limiting the support member 70 and preventing the slide rail 80 on the support member 70 from sliding off on the bending portion 201. Specifically, as Figure 2As shown, a card interface 503 located between the two connecting parts 202 is provided on the housing 10. When the support member 70 is connected to the card connector 20, the buckle on the support member 70 is directly connected to the card interface 503 of the housing 10. The card interface 503 can limit the card connector 20, and the shape of the card interface 503 is the same as that of the buckle, for example, both are set to be rectangular, and can also be set to other shapes, which are not specifically limited in this application. In this embodiment, the card interface 503 can be set to a concave structure, and the buckle can be set to a convex structure that matches the concave structure. The buckle is set to an elastic member. When the buckle is connected to the card interface 503, the buckle can be directly abutted against the card interface 503 due to its elasticity. When removing the back clip, it is only necessary to move the buckle in a direction away from one end of the card interface 503, so that the buckle is separated from the card interface 503, thereby removing the back clip from the card connector 20.
