A sound generator includes at least one piezoelectric vibrator including a piezoelectric element, a vibration unit in one of a non-contact state not contacting the at least one piezoelectric vibrator and a contact state contacting the at least one piezoelectric vibrator. While in the contact state, the at least one piezoelectric vibrator generates vibration in response to a signal, and causes a contact surface contacted by the vibration unit to vibrate and generate a sound to be emitted from the contact surface. The sound generator can detect driving allowed and driving denied states, and control application of a sound signal in accordance with the two states to the piezoelectric element.

Sound generator and sound generation system

An electronic apparatus that may be enabled by a user's simple operation to a touch panel, a control method of the electronic apparatus, and a control program of the electronic apparatus are provided. An electronic apparatus includes a contact detector for detecting a contact, an acceleration detector for detecting acceleration, a display for displaying an image, and controllers for controlling, when the acceleration detector detects predetermined acceleration caused by a first tap and, within a predetermined period therefrom, the contact detector detects a contact caused by a second touch, to carry out an operation based on the contact.

Electronic apparatus, control method of electronic apparatus, and control program of electronic apparatus

A sound generator includes a piezoelectric vibrator () including a piezoelectric element (), an anchor applying a load to the piezoelectric vibrator (), and a control unit () configured to control an input voltage based on a frequency characteristic, the input voltage being applied to the piezoelectric element () as a sound signal. While the load from the anchor is being applied to the piezoelectric vibrator (), the piezoelectric vibrator () deforms in accordance with the input voltage applied to the piezoelectric element () from the control unit (), and deformation of the piezoelectric vibrator () vibrates a contact surface () contacted by the sound generator, causing sound to be emitted from the contact surface ().

A device and method for selecting one option from a plurality of options is disclosed. A sequential selection of one option from the plurality of options proceeds when a detecting unit detects an operation associated with movement. A selecting unit sequentially selects one option from a plurality of options, and then the detecting unit detects if the operation associated with movement is stopped and the operation associated with movement is stopped.
