Tuning Fork Crystal question

In summary, a tuning fork crystal is a small, thin piece of metal that vibrates at a specific frequency when an electric current is applied. It is commonly used in electronic devices such as watches and radios to keep track of time and produce a steady, accurate frequency. The frequency range of a tuning fork crystal can vary, but most have a range of 32,768 Hz. It is different from a regular crystal in that it is specifically designed for a specific frequency and is typically used in electronic devices. While it can lose accuracy over time, modern tuning fork crystals are designed to have minimal changes in frequency.

I would like to understand the reason that tuning fork crystals have the negative parabolic temperature coefficient shape. Is it the material, the crystal cut or how its mounted. What is the physics behind that.

Thank you

1. What is a tuning fork crystal?

A tuning fork crystal is a small, thin piece of metal that has been cut and shaped to vibrate at a specific frequency when an electric current is applied. It is commonly used in electronic devices, such as watches and radios, to keep track of time and produce a steady, accurate frequency.

2. How does a tuning fork crystal work?

When an electrical current is applied to the tuning fork crystal, it creates a mechanical vibration at a specific frequency. This vibration is then converted into an electrical signal, which can be used to keep track of time or produce a specific frequency for electronic devices.

3. What is the frequency range of a tuning fork crystal?

The frequency range of a tuning fork crystal can vary depending on the size and shape of the crystal. However, most tuning fork crystals have a frequency range of 32,768 Hz, which is equivalent to 2^15 vibrations per second.

4. How is a tuning fork crystal different from a regular crystal?

A tuning fork crystal is specifically designed and cut to vibrate at a specific frequency, while a regular crystal can vibrate at multiple frequencies. Additionally, a tuning fork crystal is typically used in electronic devices, while regular crystals can have a variety of uses, such as in jewelry or as a component in certain types of technology.

5. Can a tuning fork crystal lose its accuracy over time?

Yes, a tuning fork crystal can lose its accuracy over time due to a variety of factors, such as temperature changes, physical damage, or aging. However, modern tuning fork crystals are designed to have a very low rate of frequency deviation, so any changes in accuracy are typically minimal and may not be noticeable to the average user.
