[0008] As a preferred embodiment of this utility model, the bidirectional screw passes through the platform, and the connection between the bidirectional screw and the platform is a rotatable connection.
[0009] As a preferred embodiment of this utility model, the slider and the bidirectional screw are connected by a threaded connection, and the slider and the groove are connected by a sliding connection.
[0010] As a preferred embodiment of this utility model, the size of the clamping ring is adapted to the size of the lower half of the vehicle speaker body.
[0011] As a preferred embodiment of this utility model, the top frame has an L-shaped structure design, and the connection between the limiting bolt and the top frame is a threaded connection.
[0012] As a preferred embodiment of this utility model, the concave surface of the socket is adapted to the lower half of the vehicle speaker body, and the connection between the vehicle speaker body and the socket is a sliding connection.
