Patent JP-S6021700-A (JP)
Title: Speaker device
Inventor: SHIMAMOTO OSAMU
IPC: H04S3/00
Filed: 1983-07-15
Abstract: PURPOSE:To obtain an excellent reproducing frequency characteristic without causing any peak or dip at a sound receiving point by driving an auxiliary speaker with a signal corresponding to the vibrating velocity of a vibrating system of a main speaker and a signal corresponding to an amplitude of the vibrating system. CONSTITUTION:After both left and right channel signals outputted from a program source 1 are amplified 2, 3, the result is impressed to the main speakers 4, 5. The vibrating velocity of the vibrating system of the main speakers 4, 5 is detected (6), (7), and the detected signals are added by the 1st adder 8 so as to obtain a signal corresponding to the vibrating speed of the main speakers 4, 5. The output signal of the adder 8 is converted into a signal corresponding to the amplitude of the vibrating system by an integration device 9, impressed to the 2nd adder 10 and also the output signal of the adder 8 is impressed directly to the adder 10. Thus, the output signal of the adder 10 is a signal where the signal in response to the vibrating velocity of the vibrating system and the signal corresponding to the amplitude of the vibrating system are added, and after the signal is amplified 11, the amplified signal drives the auxiliary speaker 12. Thus, no peak or dip is caused in the reproducing frequency characteristic at the sound receiving point.

Abstract: PURPOSE:To improve durability by forming a lubricating layer of carbon as its essential component and bonding an element of at least either of hydrogen or halogen to the carbon which is the essential component of the lubricating layer in the surface region of the lubricating layer. CONSTITUTION:The lubricating layer contains the carbon as its essential component and the element of at least either of hydrogen or halogen is bonded to the carbon which is the essential component of the lubricating layer in the surface region of the lubricating layer. The lubricating layer is formed by a sputtering method of a carbon target and is formed by first sputtering the carbon target in the inert gaseous atmosphere, adding the gas contg. the element of at least either of hydrogen or halogen to the atmosphere and sputtering the carbon target. The surface region formed with the carbon-hydrogen bond or the carbon-halogen bond has high lubricity, can escape the shearing force at the time of CSS in a horizontal direction and improves the durability of the lubricating layer. Since the C-H bond and C-X bond are formed only in the surface region, the durability over the entire part of the magnetic recording medium is improved without impairing the adhesiveness of the lubricating layer and an underlying layer.
