摘要： Disclosed herein is a digital audio signal processing apparatus of a type wherein a graphic equalizer including a plurality of filters connected in series to one another is subjected to arithmetic operation processing to be defined to thereby output the result of its processing as data therefrom. When a change-over command is generated, one filter out of the plurality of filters except for filters positioned at both ends is supplied to one of two output terminals with output data of a filter immediately before said one filter, the stored data is applied to the input of a filter immediately after said one filter and output data of a final filter is applied to the other of said two output terminals so as to define two graphic equalizers. Thus, where it is desired to carry out a change in the mode from arithmetic operation processing which defines a graphic equalizer comprising a plurality of bands to arithmetic operation processing which defines two-separated graphic equalizers comprising a plurality of bands or to the contrary, where it is desired to carry out a change in the mode contrary to the mode referred to above, the change in the arithmetic operation processing can be completed in a relatively short time.

摘要： An automatic sound volume controller for use with audio equipment mounted on a vehicle adapted that the level of an input audio signal and that of the noises coming inside the cabin in running state are detected, and the difference therebetween is obtained. By use of different gain levels reflecting the level difference, a direct sound signal and an effect sound signal are individually amplified for synthesis. This makes it possible to prevent the added effect sounds from being masked by the running noises because the level of the effect sound signal varies with the noises. As a result, the reproduced sounds supplemented by the effect sounds can be heard clearly while the vehicle is running. With the vehicle in stationary state, the effect sounds are kept from getting excessive, protecting the vehicle passengers from the unpleasant sensation conventionally associated with the apparatus of this kind.

摘要： A sound field correcting device provides for a natural acoustic localization of the outputs of right and left channels of an acoustic sound source. At least one of right and left channel audio signals is delayed to create a phase difference between the right and left channel audio signals, and to thus dislocate a sound in such a way that a listener not positioned equidistant between right and left channel sound sources may perceive the two channels equally.

摘要： An automatic volume control apparatus for use in a mobile audio apparatus in which a detection output from a noise detection section is compared with a control output applied to a volume control section, and a capacitor inserted between a control signal input terminal of the volume control section and a reference voltage point is charged/discharged by a current source section with a constant current on the basis of the output of the comparator to thereby make it possible to make the change of volume constant or linear relative to the change of noise level. Also, a control signal for a volume controller is obtained by subtracting a quantity of logarithmic change of an audio signal detection signal obtained from an audio signal detection section relative to a reference value from a value obtained by amplifying, with an amplification factor in a range of 1.5 to 2.5, a quantity of logarithmic change of a noise detection signal obtained from a noise detection section relative to a reference value, whereby the correspondence between levels of low-frequency components of, for example, 10 Hz or less and audible frequency components of in-vehicle noise becomes higher so that it is possible to perform more natural volume control.

摘要： A connecting structure reduces noise effects on an electronic device when hot docking the electronic device to mitigate against malfunctions. When a first electronic device having a first EMI shield is docked with a second electronic device having a second EMI shield, an ESD contact portion, which is connected to the second EMI shield and has higher in impedance than an EMI connecting portion, comes in contact with the first EMI shield earlier than the EMI connecting portion. Electrostatic charge carried on the first EMI shield moves slowly to the second EMI shield due to the high impedance of the ESD contact portion.

摘要： For connecting devices, an electromagnetic interference (EMI) connecting portion includes a conductor connected to a first EMI shield. An electrostatic discharge (ESD) contact portion electrically connects to a second EMI shield through a high-impedance element. The ESD contact portion electrically connects the EMI connecting portion to the second EMI shield through the high-impedance element as the ESD contact portion initially contacts the EMI connecting portion during hot docking. The ESD contact portion subsequently moves in response to the initial contact to contact a low-impedance element electrically connected to the second EMI shield and connect the EMI connecting portion to the second EMI shield through the low-impedance element.
