A High-Fidelity Earbud Solution
A High-Fidelity Earbud Solution
People have always desired to reproduce, with increasing fidelity, their visual and auditory experiences in the digital domain. Historically, audio reproduction began with monoaural audio, improved to stereo, and then further to high fidelity stereo. Currently spatial audio provides the most true-to-life experience. Spatial audio encompasses a 360-degree sound format that enables the listener to experience a surround-sound experience through a single pair of earbuds. Previously this surround sound effect could only be experienced via a multiple speaker array in a location such as a movie theater.EDOM's High-Fidelity earbuds solution brings an impressive spatial audio experience to customers. The solution adapts xMEMS' MONTARA speaker, Synaptics' low-power consumption Audio codec, and ROHM's protection components. Montara's 1mm profile, SMT-ready package, and IP58 rating for dust/water simplify system design and integration. Its fast mechanical response also results in the industry's lowest group delay and phase shift.
With EDOM's solution, consumers will benefit from enhanced audio fidelity with raised levels of clarity and detail for instruments and vocals, extremely low latency, IP58 waterproofing, combined with longer listening time.
