Latest Patents

Tanaka holds a patent for an "Audio earpiece for wideband telephone handsets." This invention provides a method of manufacturing a telephony earpiece that includes a speaker diaphragm constrained by a cap, creating a thin cavity between the two. The design incorporates a first resonance peak damped by a slow leak in the cap, while the frequency response is enhanced through a rear resonator in the cap and a front resonator on the opposite side of the diaphragm. The positioning of these resonator holes is crucial for optimal performance. Additionally, the earpiece is tuned using a second leak to adjust the amplitude of the low-frequency end response. This innovative approach has led to improved audio quality in telephony applications.
