Abstract:
A magnetic vibrator including a first magnetic portion and a second magnetic portion is disclosed. The first magnetic portion includes an inner plate, a first magnet and a second magnet. The inner plate is disposed between the first magnet and the second magnet. The second magnetic portion includes a coil and a wrapper. The coil is disposed around the first magnetic portion and wrapped in the wrapper. The wrapper has a gap corresponding to the inner plate. An interval is configured between the first magnetic portion and the second magnetic portion. When a current is occurred in the coil, the first magnetic portion and the second magnetic portion are actuated to move axially with respect to each other.
Abstract:
A heat-dissipating module is disposed within an electronic device. The heat-dissipating module includes at least one vibration element, a bracket, and a driving unit. The vibration element includes a working part and a free end. The bracket is connected with the working part of the at least one vibration element. The driving unit is connected with the bracket. When the driving unit drives the bracket to vibrate at a vibration frequency, the vibration element is moved with the bracket, and a resonant vibration causes the free end of the vibration element to generate a displacement, so that an airflow is generated at the free end of the vibration element to cool the electronic device.

Abstract:
The present invention relates to a computer system capable of adjusting the operating frequency dynamically and comprises at least a processor voltage-adjusting unit, a clock-generating circuit, at least a load-detecting unit, and a control unit. The processor voltage-adjusting unit and the clock-generating circuit produce a processor operating voltage and a clock signal, respectively, and transmit them to the processor. The load-detecting unit detects the processor for producing a detecting signal related to the load of the processor. The control unit produces a clock-adjusting signal and a processor voltage-adjusting signal according to the detecting signal and controls the processor voltage-adjusting unit and the clock-generating circuit, respectively. Thereby, the control unit can adjust the operating voltage of the processor as well as the frequency of the clock signal and hence adjusting the operating frequency of the processor. According, the purpose of adjusting the performance of the computer system dynamically can be achieved.
Abstract:

Abstract:
An anti-resonant structure for speakers includes a resonant structure which has a housing compartment, at least one elastic element located in the housing compartment that has one end fastening to the resonant structure and another end coupling with a speaker, and at least one buffer element located between the resonant structure and the elastic element to serve as a buffer interface to prevent the speaker from hitting due to elastic element and the resonant structure. The speaker is the element that generates vibration. The elastic element has an elastic section to absorb the vibration energy generated by the speaker to prevent the resonant structure from generating unwanted resonance and noises, and prevent electronic elements from being damaged by the resonant effect.
Abstract:
An attachable frame for flat display panels includes a flat display panel, a main structure, a bracing structure, a front frame and a rear frame.
