In addition, it should be noted that the pivot 312 is clamped between the first end 21a of the guiding slot 21 and the first limiting member 41, so that when the speaker mounting bracket is disassembled, even if the linking pin 422 of the second limiting member 42 protruding from the triggering portion 231 is touched by mistake, the locking piece 311 will not be ejected from the ejection opening 23 b.

In summary, the speaker mounting bracket of the present invention controls the locking member to slide in the fixing base by touching the position limiting member set, so that the locking piece can be popped out or folded in the fixing base, and the speaker can be mounted and maintained without an additional locking tool, thereby achieving the effect of improving the convenience of use.

Although the present invention has been disclosed with reference to the above preferred embodiments, it should be understood that the scope of the present invention is not limited thereto, and those skilled in the art will appreciate that various changes and modifications can be made to the above embodiments without departing from the spirit and scope of the present invention.
