Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 6, the front end frame structure shown includes a front end frame body 1, the front end frame body includes an upper beam 11, a lower beam 12, a left upright column 13 and a right upright column 14, and the upper beam 11, the right upright column 14, the lower beam 12 and the left upright column 13 are connected end to form a quadrilateral frame structure. The upper beam 11 of the front end frame body 1 is integrally formed with two accommodating grooves 3 with openings facing the rear and used for being connected with the horn 2, and the two accommodating grooves 3 are symmetrically arranged at the left part and the right part of the upper beam 1. It should be noted that the position, size and size of the accommodating groove 3 can be adjusted according to the specific layout design.

Loudspeaker 2 front end and 4 fixed connection of joint spare, the tank bottom of storage tank 3 is equipped with and corresponds complex opening 5 with joint spare 4, for handsome in appearance, terminal surface flushes with the front end frame body front surface before the joint spare. The left and right sides of the rear end of the opening 5 are respectively provided with two limit clips 6 extending backwards at intervals, the limit clips 6 are provided with limit grooves 7 towards the inner side of the opening, and the joint part 4 is provided with limit protrusions 8 correspondingly matched with the limit grooves 7.
