Using MEMS technology for speakers is still a relatively new introduction to the market of miniature speakers. Such MEMS loudspeakers have been tested and used in different applications and stirred up the waters; however, they have not yet found their ideal niche to make their big market entry. So far, the most promising application for…

More than 1 billion young people (12-35 years old) are at risk for hearing loss due to recreational exposure to loud sounds. To raise awareness for the implications of hearing loss due to unsafe contact with high volumes and continued exposure, the World Health Organization (WHO) has established the World Hearing Day on March 3rd.…

The aim of this article is to discuss the topic of acoustic privacy in audio applications, specifically in audio glasses. With earphones, this obviously becomes trivial: intra-aural earphones seal the loudspeaker into the ear canal by means of the silicon tip, which naturally offers high isolation. Intra-concha earphones do not have a sealed front volume,…

Low distortion at high SPL are the main requests every acoustical engineer has on every audio product; this is especially true for miniature speakers where size is limited. USound MEMS speakers are not immune to this area of conflict. This whitepaper describes the Active Linearization Algorithm (ALA), a signal processing method of improving USound MEMS…

USound currently offers two MEMS loudspeakers that are part of the Ganymede series: Adap UT-P2019 and Achelous UT-P2018. Adap is optimized towards maximum acceleration, making it ideal for free-field applications, whereas Achelous is optimized towards maximum excursion, making it especially suitable for occluded-ear applications. Therefore, USound MEMS loudspeakers can be evaluated in both acoustic domains:…

Most components in consumer electronics are silicon-based. The last component that is still manufactured traditionally is the loudspeaker — until now. USound is leading the revolution of the global speaker market, being the first company to introduce MEMS loudspeakers to the mass market. The thin form factor and wide bandwidth of USound MEMS speakers enable…

When we discuss what makes a headphone or earphone sound “good” and “bad”, we inevitably need to ask the question, well how should a headphone sound? Is there an objective way to answer this? Or does it all depend on personal preference? The truth, as so often, is somewhere in the middle. The first question…
