  What is an ultrasonic speaker?
  Ultrasonic High Class speaker is an acoustic device that uses high-frequency sound waves to emit sound waves. Unlike the vibration of ordinary sound media (such as air), its medium is molecules in the air, which generate ultrasound through the compression and expansion of molecules. A regular horn is an acoustic device that uses a vibrating film or coil to convert electrical energy into mechanical vibration, and then propagates sound waves through the air.
  
  Working principle: Ultrasonic speakers generate sound waves in a high frequency range, utilizing the propagation of ultrasonic waves in the air, which cannot be heard by human ears. Frequency range: Ultrasonic waves typically refer to sound waves with frequencies higher than 20 kHz. Ultrasonic speakers can produce higher frequency sound, typically between tens and hundreds of kilohertz.Non directionality: Ultrasonic speakers typically produce non directional sound, which is different from traditional speakers in that their acoustic radiation is more concentrated. This may be an advantage in some special applications, or it may require multiple ultrasonic speakers for sound field control. Not suitable for music playback: The design of ultrasonic speakers is mainly for special applications and technologies, rather than traditional music playback. Due to the inability of the human ear to hear ultrasound, they are not suitable for general entertainment audio systems. Miniaturization design: Ultrasonic speakers usually have miniaturization design, suitable for some applications that require compactness and low weight.Precision control: Due to the unique properties of ultrasound, ultrasound speakers can be used for applications that require precise sound field control, such as achieving precise spatial sound effects in virtual reality experiences

  How do ultrasonic speakers work in ultrasonic Rat Repellent ?
  FBelec speakers Due to the characteristics of high frequency, short propagation distance, and easy focusing of ultrasound, ultrasonic horns have a wide range of applications in industries, agriculture, healthcare, and other fields. For example, ultrasonic horns can be used for cleaning mechanical equipment and parts on production lines, killing flying and crawling insects, medical ultrasonic imaging and treatment, and other aspects.

  
  

  
  

  Can an ultrasonic mouse repellent be used to drive away mice?
  The ultrasonic rat repellent is a device designed using professional electronic technology and developed through years of research in the scientific community on rodents, which can generate 20kHz to 55kHz ultrasonic waves. The ultrasonic waves generated by this device can effectively stimulate and cause rodents to feel threatened and uneasy. Animals such as mice and bats communicate through ultrasound. The auditory system of mice is very developed and sensitive to ultrasound. They can determine the source of sound in the dark and rely on the ultrasound and echo they emit to return to their nests when they are not open. Adult mice can emit an ultrasound to call for help in times of crisis, and also emit ultrasound to express happiness during mating. It can be said that ultrasound is the language of mice.

  1. Using a powerful high-power ultrasound pulse to effectively interfere and stimulate the auditory system of rodents, making them unable to tolerate and feeling panicked and uneasy, exhibiting symptoms such as loss of appetite, escape, and even convulsions, can achieve the goal of driving the rodent out of their range of activity.

  
  

  2. The ultrasonic rat repellent produces 20KHz-35KHz ultrasonic waves, which stimulate the central nervous system of mice and make them uncomfortable and headache. They can't wait to escape the scene immediately to achieve the purpose of rat repellent. It is suitable for all places where rodent damage occurs, especially for power plants, substations, and other places where rat repellent is particularly effective.

  
  

  3. The ultrasonic mouse driver consists of an ultrasonic generator, a signal amplifier, a power amplifier, and a transmitting device. The ultrasonic generator uses an RC oscillation circuit to generate ultrasonic signals with a frequency of 20KHz-35KHz. The signal amplifier uses a push-pull amplification circuit to amplify the signal to 100-200 milliwatts, which is then amplified to about 3 watts by a power amplifier. The sawtooth shaped ultrasonic waves are emitted through the transmitting device.

  
  

• What is an ultrasonic mousetrap piezoelectric ultrasonic speaker?

  Rat repellent is a device that can produce 20khz-55khz ultrasonic wave by using professional electronic technology design and years of research on rats in the scientific community. The ultrasonic wave generated by the device can effectively stimulate and cause rats to feel threatened and uneasy. 
  

• This technology comes from the advanced pest control concept in Europe and America. The purpose of use is to create a "high-quality space without rats and pests", create an environment where pests and mice can not survive, force them to migrate automatically, and can not reproduce and grow within the control area, so as to achieve the purpose of eradicating rats and pests.
