[0060] As an example, in the embodiment of the present disclosure, the conference phone includes three microphones 30. In other examples, the conference phone may also include a larger number of microphones 30, such as four, five, six, etc.

[0061] Figure 3 Schematic diagram of the structure of a conference phone provided by an embodiment of the present disclosure. Figure 3 As shown, the housing 10 of the conference phone includes a first housing 12, a second housing 13 and a plurality of connecting plates 14. A circular opening 131 is provided at the top center of the second housing 13, the first housing 12 is located outside the circular opening 131, and the first housing 12 corresponds to the circular opening 131. The plurality of connecting plates 14 are arranged radially along the circular opening 131, and the connecting plates 14 are respectively connected to the first housing 12 and the second housing 13, and the first housing 12, the second housing 13 and the plurality of connecting plates 14 form a plurality of sound outlet holes 11. In the disclosed embodiment, the first housing 12 corresponds to the circular opening 131, which means that the orthographic projection of the first housing 12 on the surface of the second housing 13 away from the speaker 20 is located within the circular opening 131.

[0062] The plurality of sound holes 11 are located in the center between the first shell 12 and the second shell 13 and are distributed in a circular pattern, so that the sound of the conference phone can be evenly propagated within a range of 360 degrees, so that people in different directions can clearly hear the sound of the conference phone. Outside each sound hole 11, the surface of the adjacent connecting plate 14, the side surface of the first shell 12, and the top surface of the second shell 13 form a space similar to a horn shape, which plays a role in amplifying the sound. After the sound is transmitted from the sound hole 11, it can be propagated in the direction to which the horn-shaped space is directed.

[0063] In the present disclosure, Figure 3 As shown, the second housing 13 includes an upper housing 133 and a lower housing 134.

[0064] In the embodiment of the present disclosure, the second shell 13 includes two detachable parts, an upper shell 133 and a lower shell 134. In other examples, the second shell 13 may also be a complete whole, or include three or more detachable parts, which can be arranged according to the specific structure of the conference phone to facilitate the disassembly and assembly of the conference phone.

[0065] In some examples, the upper shell 133 and the lower shell 134 are connected by snaps and / or bolts. In other examples, the upper shell 133 and the lower shell 134 can also be bonded, for example, by double-sided tape.

[0066] like Figure 3 As shown, the top surface of the second shell 13 is a concave surface 132, the circular opening 131 is located at the center of the concave surface 132, and the connecting plate 14 is connected to the concave surface 132. Outside each sound outlet 11, the surface of the adjacent connecting plate 14, the side surface of the first shell 12 and the top surface of the second shell 13 form a space approximately in the shape of a horn. The top surface of the second shell 13 is set to be a concave surface, and the sound is less attenuated when propagating in the space approximately in the shape of a horn, which is conducive to amplifying the sound.

[0067] Figure 4 FIG. 1 is a schematic diagram of an assembly of a speaker provided by an embodiment of the present disclosure. Figure 4 As shown, the inner wall of the second housing 13 has ridges 15 , and the ridges 15 are arranged around the circular opening 131 . The speaker 20 is located in the area surrounded by the ridges 15 .

[0068] The ridge 15 is used to define the position of the speaker 20. By installing the speaker 20 in the area formed by the ridge 15 and the inner wall of the upper shell 133, the speaker 20 can be conveniently positioned and installed on the second shell 13, and the sealing of the connection position between the speaker 20 and the shell 10 is improved, so that the sound of the speaker 20 is transmitted outward through the circular opening 131. The ridge 15 is arranged around the circular opening 131, so that the sound output area of ​​the speaker 20 is completely located in the first chamber 10a, further avoiding mutual interference between the speaker 20 and the microphone 30, thereby further reducing the noise in the sound collected by the microphone 20.

[0069] In some examples, the conference phone may further include a cover (not shown), the cover is located in the second chamber 10b, the cover is connected to the ridge 15, the speaker 20 is located in the cover, the speaker 20 is covered by the cover, and the speaker 20 and the microphone 30 are further separated to prevent the speaker 20 and the microphone 30 from interfering with each other.

[0071] In the disclosed embodiment, the connecting member 21 corresponds one-to-one with the mounting hole 139. When installing the speaker 20, the connecting hole 22 is aligned with the mounting hole 139, and then screws are screwed into the connecting hole 22 and the mounting hole 139 to position and install the speaker 20 on the second shell 13.

[0072] Figure 5 Schematic diagram of the structure of a conference phone speaker provided by an embodiment of the present disclosure. Figure 5 As shown, a sealing gasket 18 is sandwiched between the speaker 20 and the second housing 13. The sealing gasket 18 can enhance the sealing performance of the connection position between the speaker 20 and the housing 10. The sealing gasket 18 is annular, and the annular sealing gasket 18 does not hinder the propagation of the sound of the speaker 20, and can ensure the sealing performance of the connection position between the speaker 20 and the housing 10.

[0073] Exemplarily, the sealing pad 18 may be a foam pad, a rubber pad, a silicone pad, or the like.

[0074] Figure 6 Schematic diagram of the structure of a conference phone provided by an embodiment of the present disclosure. Figure 6As shown, a first through hole 121 is provided at the center of the first shell 12 of the conference phone. The conference phone further includes an operating unit 40 , which is located in the first through hole 121 and connected to the first shell 12 .

[0075] like Figure 6 As shown, the operating unit 40 has a plurality of operating keys. As an example, in the embodiment of the present disclosure, the plurality of operating keys include a volume reduction key 41, a volume increase key 42, and a mute key 43. The volume reduction key 41, the volume increase key 42, and the mute key 43 are all located on the top surface of the operating unit 40, wherein the mute key 43 is located in the center of the top surface of the operating unit 40, and the volume reduction key 41 and the volume increase key 42 are respectively located on both sides of the mute key 43. The user can control the conference phone to be in different states by adjusting the operating unit 40. For example, the user can reduce the volume of the conference phone by operating the volume reduction key 41; increase the volume of the conference phone by operating the volume increase key 42; and put the conference phone in mute mode by operating the mute key 43.

[0076] In some examples, the operation key is a virtual key, and the user triggers the operation key by touching it. In other examples, the operation key is a mechanical key, and the user triggers the operation key by pressing it.

[0077] like Figure 6 As shown, the conference phone further comprises a mounting bracket 44, which is located in the first through hole 121 and connected to the first housing 12. The mounting bracket 44 is used to mount the operating unit 40.

[0078] Figure 7 Schematic diagram of an assembly of an operating unit provided by an embodiment of the present disclosure. Figure 7 As shown, the operating portion 40 is mounted on the first housing 12 via a mounting bracket 44 .

[0079] The inner surface of the first shell 12, i.e., the surface close to the lower shell 134, has a plurality of positioning posts 122, and the plurality of positioning posts 122 are arranged around the first through hole 121. The mounting frame 44 is annular, and the side wall of the mounting frame 44 has a plurality of positioning grooves 46. The mounting frame 44 is located in the shell 10, and the positioning posts 122 correspond to the positioning grooves 46 one by one, and the positioning posts 122 are stuck in the positioning grooves 46. The positioning posts 122 cooperate with the positioning grooves 46, so that the mounting frame 44 and the first shell 12 cannot rotate relative to each other. The end of the positioning post 122 can be connected with a screw, and the diameter of the screw head of the screw is larger than the diameter of the positioning post 122, so that the mounting frame 44 is pressed against the inner surface of the first shell 12 by the screw head, so that the mounting frame 44 and the first shell 12 are connected as a whole.

[0080] like Figure 7As shown, the mounting frame 44 is sleeved outside the operating portion 40, and the operating portion 40 is connected to the mounting frame 44. Exemplarily, the operating portion 40 and the mounting frame 44 can be connected by screws and / or buckles, or bonded.

[0081] Optionally, the surface of the mounting frame 44 close to the lower shell 134 has a plurality of positioning protrusions 47 , and the side wall of the operating portion 40 has a plurality of positioning holes 48 , the positioning holes 48 correspond to the positioning protrusions 47 one by one, and the positioning holes 48 are sleeved outside the corresponding positioning protrusions 47 .

[0082] The positioning hole 48 cooperates with the positioning protrusion 47 to position the operating part 40. The positioning hole 48 and the positioning protrusion 47 can also be interference fit to make the operating part 40 more firmly installed.

[0083] In other examples, the positions of the positioning hole 48 and the positioning protrusion 47 may also be interchanged, that is, the positioning hole 48 is disposed on the mounting frame 44 , and the positioning protrusion 47 is disposed on the operating portion 40 .

[0084] like Figure 6 As shown, the housing 10 of the conference phone has a wiring hole 16, which is located at the top of the second housing 13 and communicates with the second chamber 10b.

[0085] The conference phone also includes a circuit board 70, which is located in the second chamber 10b. The operation unit 40 is connected to the circuit board 70 through a harness 19, which is located in a wiring hole 16 and a sound outlet hole 11. The harness 19 extends from a sound outlet hole 11 opposite to the wiring hole 16 to the outside of the housing 10, and returns to the housing 10 through the wiring hole 16 to connect to the circuit board 70 located in the second chamber 10b. In addition, the speaker 20 and the microphone 30 can also be connected to the circuit board 70 respectively.

[0086] Since the speaker 20 is connected to the inner wall of the shell 10, the speaker 20 separates the operating part 40 and the circuit board 70, and it is inconvenient for the wiring harness 19 to extend from the first chamber 10a to the second chamber 10b inside the shell 10. Therefore, by providing a wiring hole 16, it is possible to connect the wiring harness 19 from the first chamber 10a to the second chamber 10b using a sound outlet hole 11 and the wiring hole 16.

[0087] Figure 8 Schematic diagram of the structure of a conference phone provided by an embodiment of the present disclosure. Figure 8 As shown, the housing 10 of the conference phone further includes a limit plate 17, and the limit plate 17 and the wiring hole 16 are located between two adjacent connecting plates 14. The limit plate 17 is connected to the two connecting plates 14 and the top of the second housing 13, and there is a gap 171 between the limit plate 17 and the first housing 12.

[0088] The wire harness 19 passes through the first chamber 10 a through the sound outlet hole 11 , and the limiting plate 17 can constrain the wire harness 19 , reduce the shaking of the wire harness 19 , and also avoid entanglement between the wire harnesses 19 .

[0089] Fig. 9 Schematic diagram of the assembly of an upper cover provided by an embodiment of the present disclosure. Fig. 9 As shown, the conference phone also includes an upper cover 50, which is located on the outside of the shell 10 and connected to the top of the shell 10.

The second through hole 51 is located at the center of the upper cover 50, and the plurality of external holes 52 are distributed in a circle around the second through hole 51. The second through hole 51 is opposite to the first through hole 121, and the area where the plurality of external holes 52 are distributed covers the concave surface 132.

[0090] The upper cover 50 is located outside the housing 10 and is connected to the top of the housing 10, which can isolate impurities in the external environment outside the concave surface, preventing dust and other impurities from entering the housing 10 through the sound outlet 11 and affecting the operation of the speaker 20, thereby increasing the protection of the conference phone. The upper cover 50 has a plurality of external holes 52, which are distributed in a circle around the second through hole 51, and have less obstruction to the sound.

[0091] like Fig. 9 As shown, the outer side wall of the second shell 13 has a plurality of buckles 135 , and the upper cover 50 can be connected to the second shell 13 via the buckles 135 .

[0092] Fig.10 Schematic diagram of a buckle structure provided by an embodiment of the present disclosure. Fig.10 As shown, the outer side wall of the upper shell 133 has a first groove 136, and the buckle 135 is located in the first groove 136.
