Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application. The present application will now be described in further detail with reference to the accompanying drawings and specific examples.

Referring to fig. 1 and 2, the present embodiment provides a speaker assembly including a speaker 10, a carriage 20, and a mounting base 30. The loudspeaker 10 has a first position and a second position. The carriage 20 is located on the back of the loudspeaker 10, the carriage 20 being fixedly connected to the loudspeaker 10. A mounting base 30 is located on the back of the speaker 10. The mounting seat 30 is fixedly connected with the carrier. The sliding frame 20 is slidably connected to the mounting base 30. The carriage 20 slides relative to the mount 30 to switch the speaker 10 between the first position and the second position.

The carriage 20 is slidably coupled to the mount 30, and the carriage 20 is slid relative to the mount 30 to change the position of the speaker 10. For ease of description, the first position is defined as the position of speaker 10 proximate to mount 30. The second position is defined as the position of speaker 10 away from mount 30. When the speaker 10 is located at the first position, the distance between the speaker 10 and the mounting seat 30 is short, so that the space occupied by the speaker assembly can be reduced, the speaker assembly can be conveniently arranged on the carrier, and the aesthetic feeling is improved. When the speaker 10 is located at the second position, the distance between the speaker 10 and the mounting seat 30 is relatively long, so that the mounting seat 30 and/or the supporting body are prevented from interfering with the maintenance of the speaker 10, and the user can conveniently maintain the speaker 10. The change of the position of the loudspeaker 10 can also be used to change the distance between the loudspeaker 10 and the user, thereby changing the volume and changing the amplification effect of the loudspeaker 10.

The front surface of the speaker 10 refers to an end surface of the speaker 10 facing a direction in which sound is emitted. The back of the speaker 10 refers to an end face of the speaker 10 facing away from the sound emission direction. The supporting body includes, but is not limited to, a wall of any building or a wall of another object, such as a wall of a station, a wall of a residential building, a wall of an office building, a cabinet of a cabinet, and the like. The carrier may be any carrier on which the speaker assembly can be carried, and the embodiments of the present application are not limited thereto.

In one embodiment, referring to fig. 1 and 2, the supporting body is a station wall, and the station wall includes a concrete wall and a decorative surface material spaced apart from the concrete wall. The decorative plane materiel is formed with the opening, forms installation space between concrete wall and the decorative plane materiel, and opening and installation space intercommunication, mount pad 30 and concrete wall fixed connection. Therefore, the loudspeaker assembly is guaranteed to be firmly installed, safe and reliable. In a state where the speaker 10 is located at the first position, at least a part of the speaker 10 is located in the installation space, and in a state where the speaker 10 is located at the second position, the speaker 10 can be separated from the installation space through the opening. That is, the speaker assembly may be the above-mentioned embedded speaker assembly, and the speaker 10 is embedded in the wall body of the station, so that the decoration surface material is consistent with the appearance of the speaker 10, thereby hiding the speaker 10 and improving the aesthetic property. When the speaker 10 needs to be inspected, a force can be applied to the speaker 10, so that the speaker 10 and the sliding frame 20 slide to the second position relative to the mounting seat 30, and at this time, the speaker 10 is located outside the decoration surface material, and the speaker 10 can be inspected without destroying the decoration surface material for the second time. After the maintenance is completed, the force is applied to the speaker 10 so that the speaker 10 returns from the second position to the first position.

It is understood that at least part of the loudspeaker 10 located within the installation space means: the speaker 10 may be entirely located within the installation space; the loudspeaker 10 may also be partly located in the installation space. Of course, the sound emitting surface of the speaker 10 faces outside the installation space, and thus, the sound of the speaker 10 is facilitated to be propagated outward.

It should be noted that the station may be a high-speed railway station, or may also be an urban railway station, for example, an inter-city railway station or an underground railway station, and the above is merely an example, and the embodiment of the present application does not limit the type of the station.

Of course, the speaker assembly provided in the embodiment of the present application may be the embedded speaker assembly or a wall-mounted speaker assembly, that is, the speaker assembly may also be directly hung on a wall, a column, or a wall of any other object of a building, for example, the speaker 10 may be directly hung on a concrete wall, and no decorative surface material is provided outside.
