Title: Loudspeaker with a diaphragm stiffening element
Inventor: CORYNEN DAVID
IPC: H04R7/12
Filed: 2007-05-03
Abstract: The loudspeaker includes a frame 101, a motor unit 105, and a membrane or diaphragm 103. The diaphragm has an inner edge 104b, an outer edge 104a which is suspended from the frame, and it extends around the motor unit 105. The diaphragm includes a dished portion 104c which has a depth that increases from said inner and outer edges towards a base region of the dished portion located between said edges.

Title: Equalization signal level control in magnetic recording device
Inventor: SKAUG STEFFEN
IPC: G11B20/10
Filed: 2007-07-09
Abstract: A magnetic recording device write channel 10 includes a write equalization (WEQ) encoder 16 for generating a write equalization level signal 28 and a digital to analogue converter 24 for converting the write data signal to analog signals for recording. The write equalization level signal from the write equalization encoding device controls an impedance value at an output of said digital-to-analog converter. The output of the digital-to-analog converter is connected to an input of the data transmission line 36 which transmits the write data signal to a write head 38 of the magnetic recording device. Variation in the output impedance of the digital-to-analog converter by comparison to the input impedance of the transmission line controls the level of the equalization signals transmitted to the write head of the magnetic recording device. The impedance mismatch of the equalization pulses results in the equalization signal being of different amplitude (54) than the data part of the signal (56).
