发明名称 Phase independent surround speaker
摘要 A speaker is disclosed that can be positioned as either a right or left front surround or a right or left rear surround in any surround sound system. The speaker includes a housing including a first driver, a second driver, a third driver, and a fourth driver. A high pass filter is connected with the first and third drivers and the first and third drivers are wired having opposite polarities from one another such that the first driver is out of phase with the third driver by 180 degrees. A low pass filter is connected with a lattice filter, wherein the low pass filter is configured to shift a phase of an input signal −90 degrees and the lattice filter is configured to shift the phase by adding +45 degrees thereby forming a −45 degree phase shift. An output of the lattice filter is connected with the second and fourth drivers.

主权项 1. A speaker, comprising: a housing including a first driver, a second driver, a third driver, and a fourth driver; a high pass filter connected with said first and third drivers, wherein said first and third drivers are wired having opposite polarities from one another such that said first driver is out of phase with said third driver by 180 degrees; and a low pass filter connected with a lattice filter, wherein said low pass filter is configured to shift a phase of an input signal −90 degrees and said lattice filter is configured to shift said phase by adding +45 degrees thereby forming a −45 degree phase shift in said input signal, wherein an output of said lattice filter is connected with said second and fourth drivers.
