Analog and digital microphones

Understanding How MEMS Microphones Work

MEMS microphones consist of a MEMS sensor and an ASIC. The sensor comprises a pressure-sensitive diaphragm, a perforated stationary plate, and a housing. Sound pressure is converted into capacitance changes, which are then processed by the ASIC into digital or analog outputs. The diaphragm and plate’s interaction under acoustic influence creates a variable capacitor, generating an AC voltage – the microphone’s output signal.

Delving into the Components

The diaphragm, a key component, is a thin membrane that reacts to incoming sound waves, altering the capacitance by changing its distance to the backplate. The backplate and the air gap between it and the diaphragm are crucial in defining the microphone’s sensitivity and signal-to-noise ratio.

Innovative Power Supply Design

Mastering Haptic Feedback: A Comprehensive Guide to Actuators

In an era where digital interaction is ubiquitous, the human senses still play a pivotal role in our experience of the world. Traditional products have relied heavily on sight and hearing to convey information. However, the realm of tactile feedback, or haptics, is gaining prominence, revolutionizing user interfaces across industries such as consumer electronics, Augmented/Virtual Reality (AR/VR), Internet of Things (IoT), automotive, and medical sectors. Haptic technology empowers engineers and designers, providing them with unprecedented control to craft intuitive user interfaces. This guide delves into the world of haptic feedback, spotlighting electromechanical actuators—a prevalent method for stimulating the mechanoreceptors in our body sensitive to vibrations.

Understanding Electromechanical Actuators

Electromechanical actuators, the crux of haptic feedback, come in four primary forms: Eccentric Rotating Mass (ERM), Linear Resonant Actuators (LRA), Voice Coils Actuators (VCA/VCM) and Piezoelectric Actuators (PA). Each category brings unique characteristics and is suited for specific applications. From the low-frequency rumble of ERM actuators to the precision and quick response of LRAs, and the realistic haptic sensation of VCAs to the energy efficient wide frequency range of PA, understanding these technologies is crucial for integrating effective haptic feedback into your products.

Eccentric Rotating Mass (ERM)

ERM actuators operate on a simple yet effective principle: an off-axis rotating mass attached to a DC motor. The frequency of the vibrations correlates with the mass’s rotation speed, offering a tactile experience that’s directly influenced by the driving voltage. ERMs are particularly noted for their ‘rumble’ effect, making them ideal when precise vibration patterns aren’t critical but a noticeable tactile feedback is desired.

Linear Resonant Actuators (LRA)

In the realm of haptics, LRAs stand out for their efficiency and compact form factor. Employing principles similar to speaker technology, LRAs create vibrations through moving a mass attached to a coil, omitting the diaphragm found in speakers. This structure allows for a direct, linear response, eliminating ramp-up times and making them incredibly power-efficient. Their rapid response and ability to create nuanced vibration patterns make LRAs a popular choice in compact and power-sensitive applications like wearables and smartphones.

Linear Resonant Actuators speaker technology diagram

In an LRA, the mechanism consists of a mass attached directly to a coil, as opposed to diaphragms commonly used in speakers. Instead of producing sound, the LRA generates vibrations by moving the mass linearly when the coil is powered. This movement depends on the frequency and voltage of the input signal, allowing precise control over the vibration’s intensity and pattern.

Linear Resonant Actuators haptic product breakdown graphic

Voice Coils (VCA/VCM)

Voice Coil Actuators (VCAs), also referred to as Voice Coil Motors (VCMs), take haptic feedback to the next level. By increasing the actuator’s size and mass, VCAs produce a more substantial and realistic vibration effect. A notable aspect of VCAs is their ability to replicate auditory effects alongside tactile feedback, enriching the multisensory experience. However, this increased capability comes at the cost of higher power consumption, a factor that designers must consider.

A notable aspect of VCAs is their ability to replicate auditory effects alongside tactile feedback, enriching the multisensory experience. However, this increased capability comes at the cost of higher power consumption, a factor that designers must consider.

LRA and VCA actuators operate best at specific frequencies, delivering the strongest vibrations within a narrow range. Designers must keep these devices close to their optimal frequency through control mechanisms. In contrast, ERMs offer a broader range of operation, as their vibration intensity varies with voltage, not frequency, giving designers more flexibility in frequency choice. Each actuator type has its own advantages and trade-offs that designers should consider for their product needs.

Piezoelectric Actuators (PA)

In contrast to alternative actuators, piezoelectric actuators leverage the piezoelectric effect as their core principle for generating haptic feedback with remarkably low power consumption. These devices are perfect when precise control and movement are required in a compact, thin profile- with a unique sense of touch for high-quality tactile effects. They exhibit efficient operation across an extensive frequency range, featuring rapid response times due to the absence of mass to be moved.

Choosing the Right Actuator

Selecting the ideal actuator is a critical step in haptic design. Factors such as desired vibration strength, precision, power consumption, and form factor play a significant role in this decision. While ERMs offer a broad range of operation due to their voltage-based vibration variation, LRAs and VCAs provide more nuanced control over vibration strength and frequency, albeit within a narrower operational band.  Piezoelectric actuators (PAs) offer efficient operation across a broad range

Integrating haptic feedback into product design opens a new dimension of user interaction. Whether used in conjunction with other sensory inputs or as a standalone communication method, haptic actuators enrich the user experience significantly. As we continue to push the boundaries of what’s possible in user interface design, understanding and harnessing the power of haptic technology will be paramount.

These miniature marvels are revolutionizing the way we experience voice communication and audio recording. With their compact size, energy efficiency, and remarkable sound quality, MEMS microphones are the go-to choice for smartphones, IoT devices, automotive systems, and more.

Whereas the electronic circuits are fabricated using integrated circuit (IC) process sequences (e.g., CMOS, Bipolar, or BICMOS processes), the micromechanical components are fabricated  using compatible “micromachining” processes that selectively etch away parts of the silicon wafer or add new structural layers to form the mechanical and electromechanical devices.

What Are MEMS Microphones?

MEMS microphones are composed of a MEMS sensor and an application specific integrated circuit (ASIC). The sensor includes a pressure sensitive movable diaphragm, perforated stationary plate and a housing.

MEMS microphones are a type of microphone that utilizes microelectromechanical systems technology to convert sound waves into electrical signals. Unlike traditional condenser or dynamic microphones, MEMS microphones are exceptionally small, typically measuring just a few millimeters in size. Despite their diminutive stature, these microphones deliver remarkable audio quality and offer numerous advantages.

The sensor converts incoming sound pressure entered through a sound inlet (top or bottom port) to a capacitance change. The ASIC manages the polarization and generates either a PDM or I2S digital output or an analog output. The diaphragm and the plate act as a variable capacitor and will, under the influence of an acoustic input, produce an AC voltage (the microphone output signal) that is processed by the ASIC.

As technology continues to advance, MEMS microphones are expected to play an even more prominent role in our lives. PUI Audio is continuing to work hand-in-hand with our customers to develop innovative solutions that solve real-world problems. Curious to learn more about MEMS technology?
