The production of a sound wave

The production of a sound wave

* Ultrasound produced by the adapter. Adapter is a device that takes power from one source, and conversion of energy to another form, such as electricity to the sound waves. Sound waves start with the mechanical movement (vibration) of the crystal which was excited by electrical pulses, and this so-called impact Kahrdgtip.
* We adapter


* The sound waves emitted from the crystal-like sound waves emitted from the loud speaker. Frequencies emitted is in the range (2 - 15MHz) and unable to be heard by the human ear. Several crystals arranged together to form the adapter. It is the adapter that sound waves through the deployment of tissue to be reflected as echoes and returned again to the adapter.
* The sound produced using electricity generated by the pressure which is the ability of some materials (notably crystals and certain ceramics) to generate an electric charge in response to the application of mechanical stress, the opposite applies when
* The word is derived from the reverse piezoelectric effect in this exhibition materials direct impact Kahrdgtip effectconverse Kahrdgtip (production of stress and / or crystals will appear in the form of the maximum change of about 0.1% of the original dimension.

Pulse

* Minute electrical impulses from the device ultrasound make the switch from the creation of sound waves at the desired frequency. The sound is either by focusing on the form of adapter (curved, linear and sector), or a group of pulses from the device control ultrasound. This produces the required focus in the form of sound wave from the face of transducer. Wave travels in the body and comes to focus on the depth required.


* In an adapter from the sound of rubber material can be transmitted efficiently in the body. This rubber coating is required for matching good resistance and allows the transfer of energy from the adapter to the patient and vice versa. To assist in the transmission of sound waves of water on the basis of gel placed between the patient's skin and jelly probe.The found a good voice dialing with the body, because the air is a very good acoustic reflector.
