SELECTABLE OUTPUT PIEZO SOUNDER DRIVER FROM DIODES INCORPORATED DRIVES HIGHER SPL AND LONGER RUNTIMES

SELECTABLE OUTPUT PIEZO SOUNDER DRIVER FROM DIODES INCORPORATED DRIVES HIGHER SPL AND LONGER RUNTIMES

Diodes Incorporated introduces the PAM8907 piezoelectric sounder driver, for maximizing sound pressure level (SPL) delivery from a ceramic/piezo sounder. The PAM8907 has a built-in synchronous boost converter, which extends SPL in battery-powered systems and outperforms other similar sounder drivers. The device is optimized for use in wireless trackers, industrial alarm systems, medical equipment, and domestic appliances. The wide 1.8 V to […]

Hee Haw Sound

Hee Haw Sound

This experiment creates a Hee Haw sound for an alarm. The diagram shows the number of cycles for the HEE and the time taken for each cycle, equates to a certain length of time. The frequency of the HAW is lower and the number of cycles must be worked out so that the time for the

Game Play

Guitar Hero MMMMDCCLX

Introduction: We created our own version of Guitar Hero which can play any song that has a MIDI file by using our custom controller and UI. We are big fans of the original Guitar Hero game, but felt limited by its inability to only play a set of songs. We came up with the solution, Guitar

Sound Localization

INTRODUCTION We constructed a triangular arrangement of microphones to localize the direction an arbitrary sound is coming from. By recording input from the three microphones, we can cross-correlate the recordings to identify the time delay between the audio recordings. Since the physical placement of the three microphones are known, the direction of the sound can

Bamboo Flute

Electronic Flute

High-level Design The goal of this project is to create an electronic flute. The musical instruments like keyboards, guitars, etc. have adjustable keys in order to play sounds at different scales. However, flutes are designed for only one scale and therefore need to be changed to play music on another scale. Hence, our electronic flute

One Pedal To Rule Them All

One Pedal To Rule Them All

Introduction Audio effects are used in nearly every recorded and live song across genres, whether its reverb being added to a vocalist or noise being filtered from a drum track. When used with guitars, they’re so ubiquitous that the interesting tones they create are often already associated with the instrument (like distortion), although they can

XMEMS LAUNCHES MONTARA WORLD’S FIRST MONOLITHIC TRUE MEMS SPEAKER

XMEMS LAUNCHES MONTARA, WORLD’S FIRST MONOLITHIC TRUE MEMS SPEAKER

Today xMEMS Labs emerged from stealth mode to reinvent sound with the introduction of Montara, the world’s first monolithic true MEMS speaker, delivering high fidelity, full-bandwidth sound and low total harmonic distortion (THD) for sealed in-ear personal audio devices, including true wireless stereo (TWS) earbuds. Montara is also the world’s first IP-57 rated microspeaker, enabling water and dust-resistant earbuds. Consumers will benefit from enhanced
