The present invention relates to a multi-functional subminiature speaker, more particularly, to a bone conduction speaker, which can generate vibration for bone conduction, bodily sensation of vibration, speaker attachment, and the vibration mode over the housing unit, that is, over a front protector of the speaker, a housing, and an outer side of a rear cover, without any projections, and which has an acoustic portion unit further detachably mounted. According to the multi-functional subminiature speaker of the present invention, it is possible to perform the bone conduction without the projections because the vibration can be generated over the whole surface of the multi-functional subminiature speaker, that is, over the whole outer side of the housing unit, by constructing such that loss of the magnetic force transmitted to the vibration coil is minimized by disposing the magnets on both inner and outer sides with respect to the vibration coil, the vibration force has been improved by making the vibration weight unit to be constructed of the yoke, the central and external magnets, and the inner and outer top plates integrally by means of the rivet shaft to thereby increase the weight of the vibration weight, and the corrugated cross-type vibration spring is provided that is adapted to generate the vibration over the whole housing unit in such a manner as to vibrate the vibration weight of the increased weight effectively and to generate vibration in the upward and downward directions as well as in the right and left directions. Also, it is possible to implement the bone conduction of wide-band region by providing the multi-functional subminiature speaker as described above, and it is possible to provide the multi-functional subminiature speaker capable of performing the bone conduction of subminiature security mode, bodily sensation of vibration, speaker attachment, and vibration mode with low manufacturing cost.

The invention relates to a system including a machine capable of retrieving data from a recording medium and of executing a program retrieved from the recording medium in response to an instruction given by an operator to the machine. Particularly, the invention relates to a system which comprises of such machine and a control unit connected to the machine for controlling the machine. The control unit includes: a housing; a pair of diverging grips which are molded integral with said housing and are supportable by both palms of the operator; a plurality of finger-manipulatable controllers mounted on the housing; and a vibration motor mounted within at least one of the grips via a adapter. The vibration motor includes: a casing; a freely rotatable shaft supported by the casing; an eccentric member, mounted on the shaft, having a rotor mounted on the shaft and a plurality of coils mounted on the rotor. Accordingly, when the coils are activated by the electric current, the motor is set in vibration caused by the rotation of the eccentric member. The vibrations of the motor is transmitted to the operator via the grips, thereby providing the operator with enhance virtual reality in the game.

The present invention provides a camera system which is provided with signal processing control means for changing the filter characteristic of parallel vibration signal processing means in conformity with the output signal of rotation vibration signal processing means and thereby can photograph an image suffering little from blur even during macro-photographing.

A process for depositing a film at a high rate and with superior step coverage properties, which comprises installing a pair of electrodes crossing with another pair of electrodes making a right angle with respect to the another pair, and applying a high frequency power differing in phase to the electrodes in order to apply a high frequency power having a Lissajous' waveform in the reaction space during the deposition of a film on a substrate.

A hand-operated power tool (10), in particular a drill hammer and / or jackhammer, has a housing (11) which has a drive mechanism for driving a tool (12) that is receivable in a tool receptacle (13) and, in the rear region (14), remote from the tool receptacle (13), has a handle assembly (20) for grasping and handling that engages the housing (11). The handle assembly (20) is vibration-damped with respect to the housing (11), with the components contained in it, at least and substantially in the axial direction, by means of a vibration-damping device (FIG. 1).
