Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description will be provided with reference to specific embodiments.
As shown in fig. 1 and 2, the present invention provides a woofer for an automobile, which includes a speaker body 11, a cone 21, and a sound cavity box 31, wherein the speaker body 11 is disposed in the cone 21, and the cone 21 is disposed on a top plate 33 of the sound cavity box 31; the inner cavity of the sound cavity box 31 is a sound cavity 32, the volume of the sound cavity 32 is larger than that of the inner cavity of the cone 21, and the inner cavity of the cone 21 is communicated with the sound cavity 32; the sound cavity box 31 is positioned on the back of the loudspeaker body 11; the sound cavity box 31 is provided with a vent hole 35 communicated with the sound cavity 32, and the sound cavity box 31 is further provided with an installation part connected with a vehicle door metal plate.
According to the bass loudspeaker for the automobile provided by the embodiment of the invention, the sound cavity box 31 is arranged below the sound cone 21 and is positioned on the back of the loudspeaker body 11, compared with a cavity in a door, the sound cavity 32 of the sound cavity box 31 has better sealing performance, and meanwhile, the size of the sound cavity 32 can be flexibly arranged according to requirements, so that the low-frequency sensitivity and the low-frequency sound effect of the loudspeaker can be effectively improved by utilizing the sound cavity 32.
Further, the sound cavity box 31 is a rectangular box; the sound cavity 32 is a flat cavity, so that space is saved, installation is facilitated, and the space utilization rate of the vehicle body is improved.
In particular, the vertical distance between the bottom plate 34 and the top plate 33 of the acoustic chamber 31 is between 50mm and 100 mm. It can be understood that the size of the sound cavity 32 can be determined according to the distance between two body metal plates of the actual vehicle door.
In an embodiment provided by the invention, the number of the mounting parts is three, and each mounting part is distributed on the bottom plate of the sound cavity box in an isosceles triangle structure, so that the sound cavity box and a vehicle door sheet metal are stably and reliably connected.
In another embodiment provided by the invention, the number of the mounting parts is four, and the mounting parts are respectively arranged at four corners of the bottom plate of the sound cavity box, so that the connection between the sound cavity box and a vehicle door sheet metal is more reliable.
