[0021] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a wide-directional smart speaker 10 includes: a mounting shell 100 and a speaker assembly 200. The mounting shell 100 has a first mounting hole 110 and two second mounting holes 120 respectively. The central axis of the first mounting hole 110 intersects the central axis of the two second mounting holes 120 at a point. The central axes of the two second mounting holes 120 are perpendicular to the central axis of the first mounting hole 110. The included angle formed by the central axes of the two second mounting holes 120 is an obtuse angle. The speaker assembly 200 includes: a first horn 210 and two second horns 220. The first horn 210 is disposed in the first mounting hole 110, and each of the second horns 220 is disposed in the second mounting hole 120.

[0022] In this embodiment, the mounting shell 100 is a hollow, hemispherical shell structure. A first mounting hole 110 and a second mounting hole 120 are respectively formed on the mounting shell 100. The central axes of the two second mounting holes 120 intersect the central axis of the first mounting hole 110 at a single point. The central axes of the two second mounting holes 120 are perpendicular to the central axis of the first mounting hole 110, and the included angle formed by the central axes of the two second mounting holes 120 is an obtuse angle. The first speaker 210 of the speaker assembly 200 is assembled in the first mounting hole 110, and the two second speakers 220 are assembled in the two second mounting holes 110. Within the mounting hole 120, the central axis of the first speaker 210 coincides with the central axis of the first mounting hole 110, and the central axis of the second speaker 220 coincides with the central axis of the second mounting hole 120. By precisely assembling the first speaker 210 and the two second speakers 220 onto the mounting housing 100, the wide-directional smart speaker 10 can have a wide directional range and excellent directivity on a plane, thus having a wide sensing range and gesture control range.

The first through holes 211 and the first threaded holes 112 are movably aligned. The first end of the first locking bolt 310 passes through the first through hole 211 and is screwed into the first threaded hole 112. The second end of the first locking bolt 310 abuts against the outer edge of the first through hole 211, so that the first speaker 210 can be assembled on the mounting shell 100 by means of threaded connection.

Specifically, the number of second threaded holes 122 is set to two, and the number of second through holes 221, the number of second locking bolts 320, and the number of second threaded holes 122 are equal. The second through holes 221 and the second threaded holes 122 are movably aligned. The first end of the second locking bolt 320 passes through the second through hole 221 and is screwed into the second threaded hole 122. The second end of the second locking bolt 320 abuts against the outer edge of the second through hole 221, so that the second speaker 220 can be assembled on the mounting shell 100 by means of threaded connection.

[0028] In one embodiment, such as Figure 3 As shown, the wide-directional smart speaker 10 further includes: a first connecting gasket 410, which is disposed in the first mounting groove 111.

Specifically, the first surface of the first connecting gasket 410 movably abuts against the bottom of the first mounting groove 111, and the second surface of the first connecting gasket 410 movably abuts against the second end of the first speaker 210. By providing the first connecting gasket 410, the first connecting gasket 410 can absorb vibration energy through its own deformation and isolate vibration transmission, thereby preventing the mechanical vibration generated when the first speaker 210 is working from causing resonance or abnormal noise, which would lead to deterioration of acoustic performance. At the same time, the first connecting gasket 410 can also enhance the connection stability and prevent loosening by increasing the contact area, so that the first speaker 210 can be more stably assembled on the mounting shell 100.

[0029] In one embodiment, such as Figure 3As shown, the wide-directional smart speaker 10 further includes a second connecting gasket 420, which is disposed within the second mounting groove 121.

Specifically, the first surface of the second connecting gasket 420 movably abuts against the bottom of the second mounting groove 121, and the second surface of the second connecting gasket 420 movably abuts against the second end of the second speaker 220. By providing the second connecting gasket 420, the second connecting gasket 420 can absorb vibration energy through its own deformation and isolate vibration transmission, thereby preventing resonance or abnormal noise caused by mechanical vibration generated during the operation of the second speaker 220, which could lead to deterioration of acoustic performance. Simultaneously, the second connecting gasket 420 can also enhance connection stability and prevent loosening by increasing the contact area, allowing the second speaker 220 to be more stably assembled on the mounting shell 100.

[0030] In one embodiment, such as Figure 3 As shown, a first limiting groove 113 is provided on the side wall of the first mounting groove 111, and a first limiting protrusion 212 is provided on the outer edge of the first horn 210. The first limiting protrusion 212 is fitted into the first limiting groove 113. Specifically, the opening direction of the first limiting groove 113 is perpendicular to the opening direction of the first mounting groove 111. By having the first limiting protrusion 212 on the second end of the first horn 210 fitted into the first limiting groove 113, the position of the first horn 210 in the first mounting groove 111 can be restricted, thus playing a role in vibration resistance and preventing loosening, improving the reliability of the assembly of the first horn 210. It can also play a role in precise positioning, avoiding the situation of the first horn 210 being misaligned. At the same time, it can also make the first through hole 211 on the first horn 210 quickly aligned with the first threaded hole 112, which is convenient for rapid assembly.

[0031] In one embodiment, such as Figure 3As shown, a second limiting groove 123 is provided on the side wall of the second mounting groove 121, and a second limiting protrusion 222 is provided on the outer edge of the second horn 220.

By having the second limiting protrusion 222 on the second end of the second horn 220 fitted into the second limiting groove 123, the position of the second horn 220 in the second mounting groove 121 can be restricted, thus playing a role in vibration resistance and preventing loosening, improving the reliability of the assembly of the second horn 220. It can also play a role in precise positioning, avoiding the situation of the second horn 220 being misaligned. At the same time, it can also make the second through hole 221 on the second horn 220 quickly aligned with the second threaded hole 122, facilitating rapid assembly.
