Abstract

A loudspeaker has an alarm and a luminous element, these being an improvement upon exiting loudspeakers having luminous elements. The luminous element is an illuminating lamp. A radiative cooling fin is mounted near the illuminating lamp. The use of radiator cooling firework permits a larger power light to be selected as the luminous element. This makes the loudspeaker capable of functioning as a substitute light source within an area. Also, the assembly employs an alarm with the loudspeaker. The brighter light emitted by the illuminating lamp on each loudspeaker provides better illumination. The lamp may also flash according to pre-programmed directions for the purpose of indicating a path and thereby helping people to escape from danger. Further, where the external power source fails, the loudspeaker assembly has a built-in emergency power source, ensuring that the loudspeaker and the illuminating lamp can still work normally.

Claims

1. A loudspeaker with a luminous element, including a magnet (12), a focusing T-yoke (11), a top plate (13) on the magnet, and a speaker frame (14), speaker cone (17), voice coil (16) and spider (15) mounted to the adaptor;

a luminous element is held in a reflection cup (4), and is fixed on the T-yoke (11);

the luminous element is an illuminating lamp (2), and the illuminating lamp mounts to a heat radiator (3).

2. The loudspeaker with a luminous element of claim 1, wherein the speaker frame has a grill (18);

the illuminating lamp and the reflection cup (4) are fixed on the T-Yoke (11) by a radiator tube (34), the edge of the reflection cup (4) and the illuminating lamp (2) on the said grill (18) being exposed, and the radiator tube (34) and T-yoke (11) define the heat radiator (3).

3. The loudspeaker with a luminous element of claim 1, wherein:

said T-yoke (11) has a central bore, in which said illuminating lamp (2) and reflection cup (4) mount;
