OMNI-DIRECTIONAL GLOBULAR SPEAKER SYSTEM |
摘要 |
An omni-directional globular speaker system employs a substantially globular speaker baffle, a plurality of speakers attached to an entire peripheral surface of the speaker baffle, and means for variably adjusting the audio output of a preferred speaker out of a plurality of speakers. The directivity characteristic of the globular speaker system is omni-directional and of a spherical form when the adjusting means is not yet variably adjusted. The variable adjusting means adjusts the directivity characteristic so that the speaker system will have a specified directivity characteristic of a non-spherical form.
