Multi-directivity sound device
First Claim
1. An apparatus, comprising:
- a plurality of sound producing units comprising at least a first sound producing unit and a second sound producing unit spaced from the first sound producing unit within the apparatus, wherein the first sound producing unit and the second sound producing unit are independent sound producing units which can produce audible sounds independent of each other;
a steering control to adjust a sound propagation direction of at least the first sound producing unit; and
a signal source to provide audio signals to the sound producing units, wherein the first sound producing unit is configured to produce a first audible sound in a first sound propagation direction and the second sound producing unit is configured to produce a second audible sound in a second sound propagation direction, wherein the first audible sound and the second audible sound are from separate sound producing units, wherein at least the first sound propagation direction of the first sound producing unit is independently adjustable based on the steering control, wherein the first sound propagation direction is changed relative to the second sound propagation direction, and where the apparatus is a portable electronic device.

Abstract
A sound producing apparatus with multi-directivity has two or more speakers to produce music or other types of audio sounds. Each of the speakers can produce audio sounds in a certain direction and at least one speaker is steerable so that its sound propagation direction relative to the others can be changed. Furthermore, one or more speakers can produce audio sounds in an adjustable angular range. One or more of the speakers can be dual-mode speakers, each of which can be operated as a wide-angle speaker or a narrow-angle speaker. With multi-directivity, it is possible to play one type of music in one direction and another type of music in another direction to suit the interests of the audience. The apparatus can be a mobile phone, an audio player, a digital or analog recorder/player, or the like.

13. A method, comprising:
-
selecting one or more of a plurality of sound producing units in a sound producing device, wherein at least a first sound producing unit and a second sound producing unit are independent sound producing units which can produce audio sounds independent of each other and in different sound propagation directions, the audio sounds being from separate sound producing units; and adjusting the sound propagation direction of at least one of the sound producing units independently of another one of the sound producing units, wherein the sound propagation direction of the at least one sound producing unit is changed relative to a sound propagation direction of the another one of the sound producing units, and wherein the sound producing device comprises a portable electronic device. - View Dependent Claims (14, 15, 16, 17)
