Device for providing built-in invisible speaker for home theater system, has speaker, elliptical reflector, and slot, where sound waves emitted by speaker is reflected by reflector and focused to navigate through slot toward listener

摘要

The device has a speaker (2), an elliptical reflector (3), and a slot (5), where sound waves emitted by the speaker is reflected by the elliptical reflector and focused to navigate through the slot toward a listener (4). The speaker is placed on a plane perpendicular to a support of an enclosure (1), to radiate the sound waves towards the elliptical reflector, where a scattering angle of the sound waves is varied by varying parameters of the reflector and an inclination of a plane of the speaker.
