[0043] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0044] Embodiment one

[0045] Please see Figure 1 The present embodiment provides a loudspeaker device 100, which comprises a loudspeaker 110, a display piece 120 and a projection assembly 130. The loudspeaker 110 comprises a shell 111 and a loudspeaker body 112, the shell 111 is configured to be mounted on the center console of a vehicle and has a hollow cavity 111a and a loudspeaker surface 111b, the loudspeaker body 112 is accommodated in the hollow cavity 111a, the loudspeaker surface 111b is provided with a plurality of loudspeaker holes 111c which are all communicated with the hollow cavity 111a, the display piece 120 is arranged on the loudspeaker surface 111b, and the projection assembly 130 is connected to the display piece 120 and is configured to be embedded in the center console of the vehicle. The projection assembly 130 is configured to project an image to the display piece 120 to realize the image display function.

[0046] In the loudspeaker device 100 described above, the projection assembly 130 can present different images on the loudspeaker 110 based on different requirements in cooperation with the display piece 120, so that the loudspeaker device 100 increases the image display function on the basis of the sound playing function, and expands the function of the loudspeaker device 100.

[0047] In the embodiment, the shell 111 comprises a bottom surface 1111, a loudspeaker surface 111b, a left side surface 1112 and a right side surface 1113. The bottom surface 1111 is configured to be attached to the center console, the loudspeaker surface 111b is connected to the bottom surface 1111, the left side surface 1112 is connected to the bottom surface 1111 and the loudspeaker surface 111b respectively, and the right side surface 1113 is connected to the bottom surface 1111, the loudspeaker surface 111b and the left side surface 1112 respectively. The bottom surface 1111, the loudspeaker surface 111b, the left side surface 1112 and the right side surface 1113 enclose a hollow cavity 111a, the distance between the left side surface 1112 and the right side surface 1113 decreases in a direction away from the bottom surface 1111, and the distance between the connecting line 111d of the left side surface 1112 and the right side surface 1113 and the bottom surface 1111 decreases in a direction away from the loudspeaker surface 111b.

[0048] Therefore, the above arrangement makes the shell 111 have a substantially semi-conical structure, which is beneficial to improve the aesthetic appearance of the shell 111.

[0049] For example, the bottom surface 1111, the loudspeaker surface 111b, the left side surface 1112 and the right side surface 1113 can have an integrated structure to simplify the manufacturing process of the shell 111, or can have a split structure to facilitate disassembly of the loudspeaker body 112 in the shell 111.

[0050] Please refer to Figure 1 and Figure 2 In the embodiment, the projection assembly 130 is arranged on the side of the loudspeaker surface 111b away from the loudspeaker body 112. The projection assembly 130 comprises a reflector 131, a light guide 132, a backlight 133 and a panel 134 which are sequentially stacked and arranged in parallel. A lower polarizer 135 is attached to one side of the panel 134 facing the backlight 133, and an upper polarizer 136 is attached to the other side of the panel 134 away from the backlight 133. The projection assembly 130 further comprises a light source 137 arranged on one side of the light guide 132. The light source 137 is used to emit light 137a to the light guide 132. The light 137a sequentially passes through the light guide 132, the backlight 133, the lower polarizer 135, the panel 134 and the upper polarizer 136, and then forms an image on the display 120.

[0051] For example, the panel 134 can be an LCD panel, and the light source 137 can be an LED light bar. The number and arrangement of the LED light bar can be based on the pre-formed image on the display 120. The pre-formed image can be a musical note, a cartoon pattern, a portrait, a song lyric, etc.

[0052] It should be noted that the working principle and process of the projection assembly 130 based on the pre-formed image can be directly obtained from the published documents, and will not be described here.

[0053] It should be noted that the reflecting member 131 is arranged on the side of the light guide member 132 away from the backlight member 133, and can reflect the emitted light rays 137a projected to the position of the reflecting member 131 to avoid the outflow of the emitted light rays 137a, thereby improving the imaging quality of the display member 120.

[0054] In this embodiment, the display member 120 is made of glass or resin. Therefore, the use cost of the display member 120 can be reduced by arranging glass or resin as the display member 120.

[0055] In this embodiment, a semi-transmissive and semi-reflective film (not shown) is attached to the surface of the display member 120. Therefore, the semi-transmissive and semi-reflective film attached to the surface of the display member 120 can improve the clarity of the imaging of the display member 120.

[0056] In this embodiment, the included angle between the display member 120 and the panel 134 ranges from 60° to 80°, for example, 60°, 65°, 70°, 75°, or 80°. Therefore, by reasonably configuring the included angle between the display member 120 and the panel 134, the clarity of the imaging can be realized on the basis of the miniaturization of the projection assembly 130.
