Title: Electronic circuit
Inventor: JONES PHILIP MATTHEW
IPC: H05B44/00
Filed: 2009-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electronic circuit with less power consumption than a circuit using a large-sized smoothing capacitor which is in parallel with an H-bridge.  <P>SOLUTION: A high-voltage AC power supply circuit for a capacitive load C<SB>L</SB>, includes a low-voltage DC power supply, an inductor L and an FET (S) in series. The FET (S) is pulsated, so that the inductor L can generate a voltage to charge the capacitive load C<SB>L</SB>via an H-bridge H, which is in parallel with the FET (S). A diode D prevents current discharge from the capacitive load C<SB>L</SB>while the FET (S) is in a closed state. A capacitance C<SB>s</SB>is fitted, in parallel with the H-bridge at a downstream side of the diode. A total capacitance value of a capacitance on the downstream side of the diode D and in parallel with the capacitive load is smaller than the capacitance value of the capacitive load, and larger than 10%. During its use, the H-bridge is switched in a state in which the capacitive load is charged up to a load voltage.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Speaker system
Inventor: YOSHIDA TOMOHISA
IPC: H04R1/02
Filed: 2009-04-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide a speaker system of a bass reflex system, which improves a low-pitched sound reproduction capability and is easy to be assembled, and is manufactured in a smaller and thinner size.  <P>SOLUTION: Since a duct 6 is formed using a front baffle 4 and a front grille 3, the speaker system does not require any other member for forming the duct 6. Thereby, the duct 6 is formed easily. In addition, since the duct 6 is formed in front of the front baffle 4, a sufficient room is secured in a cabinet 2. Thus, the low-pitched sound reproduction capability is improved. Moreover, since the longitudinal direction of the duct 6 is arranged along the direction of the front side of the speaker unit 1, the speaker system is manufactured in a thinner size even if the inner diameter of the duct 6 is enlarged.  <P>COPYRIGHT: (C)2011,JPO&INPIT
