Benefits of technology

[0008]Accordingly, the object of the present invention is to provide a remote control device having sufficient shielding and / or grounding properties to protect against EMI and / or ESD.

Problems solved by technology

However, the insulated cover provides no suppression of exterior EMI (Electro-Magnetic Interference) or RFI (radio-frequency interference) for the electric components received in the insulated cover, and sequentially make the signal transmission degrade.
Further, excessive static charge crowded on the electric components cannot dissipate through the insulated cover, the remote controller has insufficient grounding performance to protect against electrostatic discharges (ESD).

Embodiment Construction

[0019]The remote control device 100 in according with the present invention, with respect to operation mode, is generally similar to the control unit depicted in applied reference, U.S. Pat. No. 5,420,739. The remote control device 100 may be attached to a portable audio device (not shown), audio signals or other type signals generated by the portable audio device are transmitted via a wire link from the portable audio device, to the remote control device 100 and to an earphone or a speaker (not shown) which is connected to the remote control device 100. Control signals generated by the remote control are transmitted via the wire link from the remote control device 100 to the portable audio device for controlling functions such as sound volume, power on and off, play and stop, fast-forwarding remotely and conveniently.

[0020]With respect to FIGS. 1-4, illustrate the remote control device 100 in according with the present invention. The remote control device 1.00 comprises a first hou...

Abstract

A remote control device (100) includes an insulated housing (2, 3) including an outer surface (20, 30) plated with a conductive material for providing a suppression of EMI, an inner surface (21, 31), and a receiving space (4) defined by the outer surface and the inner surface, a printed circuit board (51) received in the receiving space, and including at least a first conductive pad (511), and a second conductive pad electrically connected to the first conductive pad by conductive trace, a cable including at least one grounding conductor electrically connected to the second conductive pad, grounding means (22) electrically connected to the conductive material and the first conductive pad for providing a sheath for ESD generated on the remote control device.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is directed to a wire remote control device, and more specifically, to a wire remote control device to control and drive portable audio devices, such as compact disk (CD) player, MP3 Player, to operate in a remote location.[0003]2. Description of Related Arts[0004]The present commercial portable audio devices, such as CD player, Walkman or MP3 Player, generally uses a remote (wire) controller, which is connected to the portable audio devices via a cable link, for controlling functions such as volume, power, tape-play, etc remotely.[0005]For example, U.S. Pat. No. 5,420,739 which issued to SMK Corporation on May 30, 1995 shows a conventional portable audio unit, a control unit connected to the portable audio unit by a cable. Audio signals are transmitted by the cable from the portable audio unit, to the control unit and to a connected earphone, control signals are transmitted from the control unit t...
