Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and/or process steps that are closely related to the solution according to the invention are shown in the drawings, while other details that are not relevant to the invention are omitted.

Referring to fig. 1-2, the following technical solutions are adopted in the present embodiment: the loudspeaker comprises a loudspeaker shell 1, a sounding component 2, a power supply module 3, a sounding horn 4, a connecting fixing seat 5, a fire-fighting sensor 6, a separation net rack 7, a sensor trigger circuit board 8 and a fixing ear edge 9; the tail part of the loudspeaker shell 1 is provided with a sound production assembly 2, the sound production assembly 2 is connected with a sound production horn 4 in the loudspeaker shell 1, and the back surface of the sound production assembly 2 is connected with a power supply module 3; the top end of the sounding horn 4 is connected with a fire-fighting sensor 6 through a connecting fixing seat 5, a circle of separation net rack 7 is arranged on the outer side of the fire-fighting sensor 6, and the outer side of the separation net rack 7 is connected with the inner wall of the loudspeaker shell 1; and the sensor trigger circuit board 8 at the inner side of the fire-fighting sensor 6 is connected with the sounding component 2.
