  • Publication number: 20030194239
    Abstract: An infrared receiving apparatus includes: a housing having an earphone adapted to be worn on a car driver's ear, an infrared (IR) receiver for receiving infrared signal as transmitted by an IR transmitter electrically connected to a cellular phone held in a car and for converting the IR signal to be audio signal to be heard by the car driver through the earphone as worn thereon, and a rotary shielding cover pivotally mounted in the housing and having an opening formed in a peripheral portion of the rotary shielding cover having a pendulum weight secured to the peripheral portion of the cover as juxtapositioned to the opening, thereby causing the cover to be gravitationally pendent to constantly orient the opening of the cover downwardly to preclude the inward projection of interference sunlight, and to exclusively allow the entrance of the IR signals from the cellular phone through the opening as gravitationally positioned at a bottom portion of the shielding cover to prevent from unexpected interference ligh
