An electronic musical instrument and a portable terminal are connected to a wireless LAN. The wireless LAN is connected to an Internet via a router. A distribution server residing on the Internet is a server which provides Internet services. A pairing between the electronic musical instrument and the portable terminal is established to conduct Internet communications in a pair. Processes from accessing the distribution server to specifying a desired service are performed by use of the portable terminal. The distribution server distributes data corresponding to the service specified by the portable terminal to the electronic musical instrument. A user is thus allowed to use the desired service on the electronic musical instrument. ,

Service provision system for electronic musical apparatus

Pedal device for an electronic keyboard instrument includes a pedal having opposed side walls extending downward from the opposite side edges, in a width direction, of an upper wall, and a reactive force imparting member which imparts reactive force to the pedal by being pressed by the lower surface of the pedal. The reactive force imparting member includes a plate-shaped base portion mounted on a mounting portion of a support member, and an upwardly-convexed dome-shaped body portion integrally formed with the upper surface of the base portion. The body portion and mounting portion each have a width dimension smaller than a distance between the opposed side walls of the pedal so that, during stroke action of the pedal, the body portion and mounting portion falls within a space between the opposed side walls.

Pedal device, and electronic musical instrument including the pedal device

A leverpivots within a certain stroke range by a player's depression of the lever. A coil springis displaceable within the entire stroke range of the leverto produce a reaction force having a characteristic that the reaction force increases with an increase in the displacement. A dome-shaped rubber memberstarts being displaced at some point in the stroke of the leverto produce a reaction force having a characteristic that the rate of change in reaction force with respect to the displacement decreases in an area placed in the displacement. The characteristic is obtained by the dome-shaped rubber membercoming into contact with the leverat some point in the stroke of the leverto start being displaced by further depression of the leverto buckle at some point in the displacement of the dome-shaped rubber member

Pedal apparatus of an electronic musical instrument

A percussion detecting apparatus capable of enhancing an effect of disturbance interception by intercepting a micro-vibration conveyed from a support frame. A pad member has a pad having a back-side surface to which a base is fixed, and a percussion sensor is disposed on a back-side surface of the base. The pad member is supported by a frame via fixing members integral with the pad member and intervening members made of silicon rubber. Vertical protrusions having different protrusion heights are formed on an upper surface of a flange of each intervening member, and horizontal protrusions are formed on an inner peripheral surface of a through-hole of each intervening member. When the pad member in an unstruck state, each fixing member is in contact with a corresponding one of the intervening members only at the vertical and horizontal protrusions of the intervening member.
