No:TM-306 The super province electricity family supersonic wave drives the mouse. The supersonic wave drives the mouse is effective in the control mouse, the cockroach, the flea, the fly, the cricket, the bookworm, Shui Ch'ung, ant and other common harmful animals. In the laboratory research demonstrated that, supersonic wave sound wave to common and harmful animal's auditory nerve system, has the aggressively, the reason lies in them to will feel the pain to 110 decibels sound pressures, then gives up their food, Shui Ho hides place but unceasing departing, but these intensity sound waves to human and the family pet such as dog, the cat, the fish, the bird, and the farm animal, all in may accept in the scope, not any influence. The supersonic wave will drive the mouse not to disturb the television, the broadcast, preserves the system, the fire detector, the heart rhythm regulator, the hearing aid, and other electric appliance equipment, also will not injure the plant. The supposition supersonic Boeing pressure surpasses above 120 decibels, can affect the dog, the cat, and the farm animal, the airplane noise only has 135 decibels, the supersonic wave piezoelectricity loudspeaker is impossible in the world to surpass above 120 decibels, the supposition has surpasses 120 decibels, the supersonic wave piezoelectricity loudspeaker possible life not long to discard.
Speakers: 1. No Bulky Magnet Structure permitting the piezo ceramic speakers to be much smaller and much lighter, and reducing the problems associated with size, weight, and stray magnetic fields. 2. No Voice Coil Reliability is greatly improved, since there are no rubbing voice coils from warped cones or from contaminants in the air gap. The low dynamic mass of the drive mechanism gives the piezo ceramic speaker a better transient response than can be obtained with a conventional dynamic speaker. 3. No Crossover Network Since the piezo ceramic speaker rejects low frequency power, a crossover network is usually not required. 4. Long Term Stability New improved drivers used in piezo ceramic speakers are impervious to normal humidity variations, stable to temperatures of 240℉(115℃), and durable under a variety of external shock, vibration and stress conditions. As results of these drivers improve mends, King state piezo ceramic speakers are capable of quality performance as long as these devices are operated within their design specifications. 5. High Impedance Over 1,000 ohms at 1KHz, and still above 20 ohms at 40KHz. 6. Low Harmonic Distortion Average harmonic distortion of less than 1% contributes to the delivery of superior sound fidelity. 7. In general, piezo ceramic speakers are used at frequency from 4K HZ to 40K HZ and have a sound pressure level of 95 to 105 dB at 1 meter, 1 watt, 8 ohm load.

No:TM-315 The province electrical form ultra formidable power supersonic wave drives the insect mouse bird Introduced: In order to improve our PEST OUT!, we have undertaken many field experiments. From these experiments, theory and results continuously indicate that pests are expelled by the direct stimulation on their central nerves, through the ultrasonic wave. The ultrasonic wave attacks the auditory and nervous system of pests causing pain and discomfort. Pests are impossible to stay. FEATURES: 1. Ultrasonic wave causes great pain and discomfort to pests but does no harm to humans and pets. It's one of the most sanitary ways to get rid of the annoying pests. 2. Frequencies range from 20 KHz to 65 KHz modulated ultrasonic waves are emitted from PEST OUT! which forces pests to leave. 3. The Ultrasonic waves emitted from PEST OUT! will not interfere with any electronic appliances. 4. In one to three weeks your infestation will be eliminated and continual use of PEST OUT! will prevent further nesting and in abitations. The purchase scope object is in the family, the apartment, the restaurant, the office, the factory, the warehouse, the hospital, the farm and the room the region all is protecting in the region scope, this product only limits the space to cover covers the scope 8,,000 square England foot.
