Title: Antti O Salo: Innovator in Acoustic Technology
Introduction
Antti O Salo is a prominent inventor based in Beijing, China. He has made significant contributions to the field of acoustic technology, holding 2 patents that showcase his innovative approach to sound reproduction and electronic devices.
Latest Patents
One of his latest patents is the Dual-mode loudspeaker. This apparatus utilizes a transducer to produce vibrations in both the ultrasonic and audible frequency ranges. A membrane or cantilever structure is coupled to the transducer to generate acoustic waves. When operating in the audible frequency range, the membrane functions like a conventional loudspeaker. Conversely, in the ultrasonic frequency range, the ultrasonic signal is modulated by an audio signal to create improved directivity. The acoustic waves in the ultrasonic frequency range can reproduce directional audible sound due to the nonlinear interaction of ultrasonic waves in air.
Another notable patent is the Electronic device with overlapping sledge portion. This electronic device consists of a first part with a first surface and a second part with a second surface that confronts the first surface. It includes a slide module with a sledge part fixed on the first surface and a base part fixed on the second surface. This slide module allows for linear movement between the first and second parts, achieving maximum overlap of the sledge part and base part with minimal overlap of the first and second parts.
