Document Type and Number:
Japanese Patent JP2020005297
Kind Code:
A
Abstract:
To provide a composite lighting and loudspeaker driver device suitable for being installed in a ceiling space.SOLUTION: A composite lighting and loudspeaker driver device 10 includes a loudspeaker driver 20, a heat removal element 120, a light source 110, and an enclosure 15. The heat removal element includes a pillar part 120a. The pillar part is thermally connected with a heat sink 40 formed near a central longitudinal direction axis to a rear of the enclosure. The light source, i.e., a heat source, is installed on a forward end of the pillar part. The pillar part optimizes heat conduction so as to be away from the light source. The enclosure has substantially cup-shape, and has a sidewall 15a. Inside of the sidewall of the enclosure is parallel with the central longitudinal direction axis of the enclosure over most of a depth rearward. As a result, a large space is formed on the back of a loudspeaker diaphragm 130, and improved sound is brought about.SELECTED DRAWING: Figure 1
