Abstract
A resonator for a vehicle heart rate detection device is disclosed. The resonator includes a chamber having a front wall and a sidewall extending circumferentially around the front wall, and the sidewall defines a rear opening opposite the front wall. A lid is secured over the rear opening, and the lid, the front wall, and the sidewall define a cavity within an interior of the chamber. A neck extends from the front wall of the resonator and defines a front opening, and a microphone is positioned within the cavity that records vibrations entering the cavity via the front opening. The cavity is filled at least partially with a first material and at least partially with a second material, and the cavity amplifies the vibrations within a target range frequency.
