An electronic device includes a housing having a plurality of surfaces and a plurality of vibration portions provided in the housing so as to be in contact with at least one of the plurality of surfaces. The plurality of vibration portions include a first vibration portion, which vibrates at a frequency included in a first frequency band, and a second vibration portion, which vibrates at a frequency included in a second frequency band that is different from the first frequency band.

This information presentation apparatus includes: an actuator that includes a movable portion and is capable of linearly driving the movable portion; a control unit that controls the actuator so that the movable portion is driven corresponding to waveform information; and a belt for attaching the actuator to a user.

A watch type terminal includes: a haptic module including a plurality of vibration elements and configured to generate a tactile effect that is sensible by a user of the watch type terminal; and a controller configured to acquire event information on the watch type terminal and controls one or more vibration elements among the plurality of vibration elements to operate in a vibration alarm pattern corresponding to the acquired event information. The watch type terminal acquires event information and operates one or more vibration elements among the plurality of vibration elements in a vibration alarm pattern corresponding to the acquired event information.

There are provided a vibration generation device and an electronic apparatus adapted to generate a variety of vibrations corresponding to a variety of situations without making the power consumption excessively high. The vibration generation device and the electronic apparatus according to the present embodiment is provided with two vibration motors having respective eccentric weights different in weight from each other, and drives a first vibration motor having a heavier one of the eccentric weights in the case of announcing a first event, for which notice with a strong vibration is necessary or effective. In contrast, in the case of announcing the second event, for which a quick response or a response performance is required, a second vibration motor having a lighter one of the eccentric weights is driven. The first events include incoming, coming of alarm time, a dynamic or important action, motion, and so on in a game. The second events include confirmation of input operation using a touch or a press on a screen of the electronic apparatus, a minute action, motion, and so on occurring in the game. Further, the correspondence between the vibration motors and the events is made selectable.

A system, method, and apparatus for monitoring ambient sound and vibration levels at the location of a user allows a determination as to whether the user is exceeding a maximum allowed exposure time as determined by an occupational standard. The sound and vibration level data can be evaluated locally at the mobile communication device, as well as transmitted to a backend system to allow supervision of personnel associated with the backend system as a further assurance that personnel comply with exposure limits. Further, the mobile communication device, in response to ambient conditions, adjusts the settings of its alerting sound and the vibration level of an associated vibration accessory to ensure perception of alerts by the mobile communication device for the user of the mobile communication device.

A computer-implemented method, computer program product, and system for determining electrical power levels using one or more sensors on a computing device including: determining threshold levels and alert criteria, receiving electrical power level data from one or more sensors of a computing device, determining if the electrical power level data exceeds the alert criteria, and sending an alert to the appropriate parties if the electrical power level data exceeds the alert criteria.

The present invention relates to a mobile terminal and a method of controlling same, and has the objective of providing a mobile terminal and a method of controlling same which allow a caller to be identified when a call signal is received without having to look at a display. The gist of the present invention is that when a call signal is received through a wireless communication unit, the calling phone number of the received call signal is identified, a melody bell sound corresponding to the identified calling phone number is output, and the key of the melody corresponds to a first number included in the calling phone number.

Provided is a vibration system using sound. More particularly, the present invention relates to a system which is capable of generating vibration using sound so that the beats of the sound may be felt, is convenient to carry or move due to a lightweight and compact size thereof, is capable of generating vibration matching a beat of sound to which a user is currently listening, is capable of generating vibrations matching various feelings according to beats of sound on the basis of user setting, thereby greatly enhancing effects that the user may feel, and is very inexpensive to manufacture.

A motor-integrated acoustic output unit, comprising: a speaker frame of which one surface and the other surface are open; a diaphragm covering an opening part of the one surface of the speaker frame and being coupled to the speaker frame; a yoke covering the other surface of the speaker frame; a motor unit which is coupled to the yoke and which has at least a portion positioned inside the speaker frame; a voice coil positioned on the circumference of the motor unit, vibrating in the directions of the one surface and the other surface, and causing the diaphragm to vibrate; and an outer magnet positioned outside the voice coil, wherein the motor unit comprises: a motor frame coupled to the yoke; a motor coil fixed to the motor frame; an elastic part of which one side is coupled to the motor frame; and a motor magnet coupled to the other side of the elastic part, implements speaker, receiver, and motor functions with one module so as to reduce a mounting space, thereby reducing the number of components such that a manufacturing process is simplified and manufacturing costs can be reduced.
