Digital audio/video playing device

Abstract

A digital audio/video playing device includes a support plate forming a plurality of depressible tabs. Each tab is formed by forming an elongate slit surrounding the tab with a small connection with the support plate to form a cantilever, elastically deflectable tab. A plurality of switch units and a touch control board are arranged between a base plate of the playing device and the support plate. A surface film is attached to the support plate and has a continuous raised-recessed configuration, including a smoothly-raised external ring section and a touch-control internal ring section to allow a user to depress the depressible tabs of the support plate and to operate the touch control board via the surface film.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to a digital audio / video playing device, in particular to an operation panel structure of a digital audio / video playing device. BACKGROUND OF THE INVENTION [0002] With the development of computer technology and digitalized multi-medium technology, computer devices are widely used in a variety of applications, such as office applications, home entertainments, and business operations. Some of the latest developments successfully combine multi-medium or digital music features in portable computer devices, such as notebook computer and thus allowing general consumers to watch multi-medium films or to listen to digital music with the notebook computers. [0003] However, due to the current trend and requirement from general consumers of miniaturization of the portable electronic devices, playing multi-medium film or digital music with the notebook computers is not the best choice for the consumers and portable multi-medi...

Benefits of technology

[0013] The present invention provides a digital audio / video playing device comprising both switch units resembling conventional pushbutton and a touch control board, both of which can be used to operate / control the playing device, realizing efficient and convenient operation of the playing device. The digital audio / video playing device of the present invention further comprises a surface film, which effects isolation of inside the playing device from the external surroundings, while allowing a user to selectively actuate the switch units and operate the touch control board. The surface film has a continuous raised-recessed configuration, defining a smoothly-raised external ring section and a touch-control internal ring section by which the user may apply a force to either depressible tabs of a support plate to selectively actuate the switch units or a touch control board for operation thereof. The smoothly-raised configuration of the surface film provides the user with a smooth tactile feeling of contact and operation. The surface film, which effects isolation of the inside of the playing device, effectively prevents foreign objects, such as dusts and humidity, from entering the inside of the playing device and thus protecting the playing device and extending service life of the playing device. Value of the playing device can also be enhanced.

Problems solved by technology

However, due to the current trend and requirement from general consumers of miniaturization of the portable electronic devices, playing multi-medium film or digital music with the notebook computers is not the best choice for the consumers and portable multi-medium player and digital music players gradually take place of the notebook computers in playing digital music or multi-medium film.

The evolution of the digital playing device, however, does not accompany any significant improvement in the operation and control panel, which means the new device is operated with the same old control panel.

However, for the miniaturized portable device, extremely severe requirement for high precision must be met in order to effect snug extension of tiny pushbuttons.

As a consequence, any defeat in quality control regarding the mechanical dimension of the parts of the playing device will lead to failure of product.

Such a structure forms an obstacle to a user's finger that slides along the surface of the casing for operating the pushbuttons.

Such a problem also exists in a variety of portable electronic devices that are currently available in the market.

Even the gap and raised rim that are commonly seen in the operation panel or control panel of the conventional portable electronic devices are made hardly felt by the user, there is still a problem of humidity penetration into the device through the tiny gap to be overcome for the conventional designs.

Humidity is one of the major causes that fail the electronic devices.
