Title: Acoustic reproducing device
Inventor: SAITO MASATAKA
IPC: H03G5/02
Filed: 1990-04-16
Abstract: PURPOSE:To suppress the influence of noise and to attenuate sound leakage when using a headphone by controlling the frequency characteristics of reproduced signals corresponding to the frequency characteristic of noise by changing over a control switch to change over a filtering operation. CONSTITUTION:Signals read out from a CD record 1 are converted to analog signals by a D/A converter 5 and reproduced by an openair type headphone 12. When turning a control switch 10 to a filter-on side terminal 10b, the reproduced output obtains the frequency characteristic reinforcing a low frequency band and attenuating a high frequency band in the ON operation of a filter 9. Therefore, since the low frequency band in the output from the headphone 12 is reinforced not so as to be drowned by the noise for a listener, the sounds are well balanced to be easily heard. Further, since the part of the high frequency band leaked from the headphone 12 is attenuated as well, any trouble caused by the sound leakage can be prevented from being given to people surrounding the listener in a train or a car.

Title: Digital-analog converter
Inventor: OONISHI TAKESHI
IPC: H03M1/08
Filed: 1979-08-10
Abstract: PURPOSE:To make the noise at low quantized bit into white noise, by producing the white noise with virtual random pattern. CONSTITUTION:The digital parallel signal fed to the input terminal 6 is fed to the upper rank M-bit from the MSB of the N-bit D/A converter 7. Further, from the M+1-th bit to N-th bit, the random pattern from the virtual random pattern generating circuit 8 is fed. Analog signal is output from the D/A converter 7 with the inputs and fed to the analog output terminal 9. At the D/A conversion, since the virtual random pattern is always present at the M+1-th bit to the N-th bit, even if the number of effective bits of the digital parallel signal is less, the quantized noise is mixed with white noise and good result in audible sense can be obtained.
