Patent number: 8160266Abstract: An active vibratory noise control apparatus has a speaker for canceling vibratory noise in the passenger compartment of a vehicle, the speaker being used as a speaker of one of different audio devices that can be installed on the vehicle. Each of the audio devices has a command key switch assembly. When the command key switch assembly is operated to turn off the transistor, a control signal is applied to a switching control circuit in an active vibratory noise control unit, which identifies the audio device installed on the vehicle. The active vibratory noise control unit generates a canceling signal matching characteristics of the speaker of the identified audio device for canceling vibratory noise in the passenger compartment.Type: GrantFiled: June 17, 2004Date of Patent: April 17, 2012Assignees: Honda Motor Co.

Patent number: 8014538Abstract: An active noise reducing device includes switchover frequency memory which stores a speaker having weaker influence of level drop or dips in gain characteristics of transmission from first speaker and second speaker both working as secondary noise generators to microphone working as a residual signal detector, and also stores a frequency band of that speaker. Output switcher appropriately and selectively switches first speaker over to second speaker in response to the noise frequency at present calculated based on the rpm of engine by frequency calculator. This structure allows the active noise reducing device to work steadily even if level drop or a dip occurs in the gain characteristics of transmission from the speaker to the microphone, and allows suppressing the occurrence of abnormal sound due to divergence or distorted sound due to excessive output. Ideal noise reduction effect can be expected.Type: GrantFiled: July 21, 2006Date of Patent: September 6, 2011Assignee: Panasonic CorporationInventors: Masahide Onishi, Yoshio Nakamura, Shigeki Yoshida

Patent number: 7620188Abstract: An active vibratory noise control apparatus reduces vibratory noise which is produced in the passenger compartment of a vehicle based on vibratory noise generated by a variable-cylinder internal combustion engine that can selectively be operated in a full-cylinder operation mode in which all of the cylinders are operated and a partial-cylinder operation mode in which some of the cylinders are out of operation. The active vibratory noise control apparatus has a partial-cylinder operation mode determining circuit for determining whether the variable-cylinder internal combustion engine is in the partial-cylinder operation mode or not. Depending on a determined result from the partial-cylinder operation mode determining circuit, a transistor is turned on or off to switch an amplifying circuit which drives a speaker into and out of operation.Type: GrantFiled: June 15, 2004Date of Patent: November 17, 2009Assignees: Honda Motor Co., Ltd., Panasonic CorporationInventors: Toshio Inoue, Satoru Minowa, Akira Takahashi, Yoshio Nakamura, Masahide Onishi

Patent number: 7574006Abstract: An active noise controller can determine the signal transmission characteristics from the power amplifier and the speaker to the microphone without using any special external measuring instrument and calculate a cosine correction value and a sine correction value without using an external computer. The active noise controller uses the cosine correction value and the sine correction value to actively reduce vibrational noise. The measurement mode is selected on touch panel (3), and correction value calculator (22) calculates cosine correction value C0 and sine correction value C1 by using filter coefficients W0 and W1 which allow error signal e?(n) to approach zero. Memory (23) stores these values C0 and C1.Type: GrantFiled: November 8, 2005Date of Patent: August 11, 2009Assignee: Panasonic CorporationInventors: Toshiyuki Funayama, Yoshio Nakamura, Masahide Onishi
