SPEAKERS SOUND LOUDEST BETWEEN 2,500Hz TO 5,000Hz DIMENSIONS ARE .580" x .425" x .225" x .425" x .580" x .275" TALL AS THE TITLE SAYS, WE ARE SELLING OFF 1 - 09 50PC LOTS OF A .58" X .58" X .275" SURFACE MOUNT, MACHINE WASHABLE, WAVE SOLDERABLE, HIGH TEMPATURE PLASTIC SPEAKER MNF'D BY A MAJOR ASIAN MANUFACTURER. I DIDN'T GET THIER SPECS THOUGH WHEN I HOOKED ONE UP TO A SIGNAL GENERATOR THEY SEEMED TO REPRODUCE THE SOUNDS FINE BUT THEY SEEMED THE LOUDEST AT FREQUENCIES BETWEEN 2.5KHz AND 5.0KHz WHICH MAKE US BELIEVE THAT THEY WERE ORIGINALY BOUGHT FOR CELLPHONE RINGERS, YOU KNOW YOU HEAR THE CELLPHONE START RINGING BUT INSTEAD OF A RINGING SOUND YOU HERE THIS HIGH FREQUENCY REPRODUCTION OF A TUNE OR SONG. WE BUILT UP A DUAL CONVERSION RECEIVER USING A MOTO SMT DUAL CONVERSION FM RECEIVER IC. WE USED AN SMALL 8 PIN SPEAKER AMPLIFIER IC TO DRIVE THIS SPEAKER WHICH WAS MOUNTED TO THE CIGARETTE SIZED PLASTIC ENCLOSURE SO THE SOUND WAS AIMED UPWARDS OUT OF THE SHIRT POCKET. WE ALSO HAD A 3.5MM PLUG FOR EARPHONES FOR ENJOYING THE SOUNDS W/O OTHERS HEARING. BUT THE SPEAKER SOUNDED SO GOOD AND SEEMED TO BE SOMEWHAT DIRECTIONAL TO THE POINT I COULD HEAR AND UNDERSTAND THE SPEAKERS OUTPUT BUT SOMEONE A FEW FEET IN FRONT OF ME COULD NOT. SO I NOW HAVE ANOTHER GREAT USE FOR THESE BABIES! MY TECH DESIGNED THESE INTO A ROCKET LAUNCHER CIRCUIT. THE CIRCUIT ONCE BUILT IS USED TO REMOTE FIRE THRU 2 WIRES OR A THRU A WIRELESS SETUP HOME MADE ROCKETS. THE OPERATOR PUTS ONE END AT THE ROCKET AND PUT THE IGNITER WIRE FROM THE REMOTE UNIT INTO THE ROCKETS ENGINE. THEN ABOUT 30 SECONDS BEFORE THE ACTUAL LAUNCH THE NE555 TIMER CIRCUIT GENERATES A VERY HIGH PITCHED WARNING SOUND TELLING OTHERS TO STAY AS FAR AWAY AS POSSIBLE. THEN WHEN THE SOUNDING STOPS THE ROCKET IS LAUNCHED. HE ALSO DESIGNED ONE INTO THE ELECTRONIC'S BAY OF HIS ROCKET AND ONCE IT WAS BLASTED FREE OF THE ROCKET IS STARTS BEEPING VERY LOUDLY UNTILL SOMEONE FINDS IT USING THIER EYES AND EARS. EVERYONE AROUND HERE HAS SAID IS A REALLY GREAT PRICE. I AM ONLY SELLING OFF THESE 450PCS IN 09EA 50PC LOTS.
