Abstract

A speaker includes a housing; a support assembly installed on the lower end of the housing to support the housing; at least one first speaker unit installed in the housing to reproduce a sound signal; and a second speaker unit installed in the support assembly to reproduce a sound signal which belongs to a low sound band. Openings are defined through both sides of the support assembly to transmitto the outside sound reproduced by the second speaker unit. A guide cone is provided to the lower end of the support assembly to guide sound toward the openings. The speaker unit can be installed in a baffle which is supported at the opened front end of the housing to be rotated about a vertical axis. Through rotating the baffle, the speaker unit can be actually rotated within a predetermined range to change a sound transmission direction.

Description

technical field [0001] The present invention relates to loudspeakers, and more particularly to loudspeakers having a wide reproducible sound frequency band and configured to allow adjustment of the angle of the speaker unit. Background technique [0002] In recent years, due to the rapid global distribution of audio and video equipment, in addition to the importance of displays, the importance of speakers has also increased, and the demand for speakers has also increased. In particular, speakers that have advantages of a small-sized bookshelf-type speaker and can be installed in a narrow space without using a separate speaker stand are becoming popular. [0003] figure 1 It is a perspective view showing the structure of a conventional speaker. refer to figure 1 , the speaker 1 has a box-shaped housing 3 that is narrow and elongated in the vertical direction. The housing 3 defines the appearance of the loudspeaker 1 . The housing 3 may have various cross-sectional shapes...
