DUAL-OPERATING ACCELEROMETER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027490 titled 'DUAL-OPERATING ACCELEROMETER

Simplified Explanation

The present disclosure is about a patent application for micro-electromechanical system (MEMS) accelerometers that can be used in both user interface mode and true wireless stereo (TWS) mode of an audio device. These accelerometers are designed with specific electromechanical parameters, including mass, stiffness, active capacitance, and bonding pressure. These parameters allow the accelerometers to have suitable resonance frequency, quality factor, sensitivity, and brownian noise density for both modes.

  • The patent application is for MEMS accelerometers used in audio devices.
  • The accelerometers are designed with specific electromechanical parameters.
  • The specific parameters enable the accelerometers to work in both user interface mode and TWS mode.
  • The accelerometers have suitable resonance frequency, quality factor, sensitivity, and brownian noise density for both modes.

Potential Applications:

  • Audio devices such as headphones, earphones, or speakers that can switch between user interface mode and TWS mode.
  • Wearable devices with audio capabilities that can utilize both modes.

Problems Solved:

  • Traditional accelerometers may not have the necessary parameters to work effectively in both user interface mode and TWS mode.
  • Switching between modes may require different accelerometers, leading to increased complexity and cost.

Benefits:

  • Simplifies the design and manufacturing process of audio devices by using a single accelerometer for both modes.
  • Reduces the cost and complexity of switching between user interface mode and TWS mode.
  • Provides a consistent and optimized performance in both modes.


Original Abstract Submitted

the present disclosure is directed to micro-electromechanical system (mems) accelerometers that are configured for a user interface mode and a true wireless stereo (tws) mode of an audio device. the accelerometers are fabricated with specific electromechanical parameters, such as mass, stiffness, active capacitance, and bonding pressure. as a result of the specific electromechanical parameters, the accelerometers have a resonance frequency, quality factor, sensitivity, and brownian noise density that are suitable for both the user interface mode and the tws mode.
