US 12,563,336 B2 · Resonator devices and assemblies thereof

Abstract

An assembly including an apparatus and a device, the apparatus including a speaker configured to generate acoustic waves defining an alarm tone and a housing enclosing the speaker. The speaker is positioned within the housing such that a front chamber is between the speaker and at least one first opening of the housing, with the acoustic waves exiting through the at least one first opening. The device is coupled to the housing and includes a body having an aperture, a cavity, and at least one second opening, the cavity being positioned adjacent to the housing and configured to receive the acoustic waves through the aperture, with the acoustic waves exiting through the at least one second opening. The aperture, the cavity, and the at least one second opening are sized to collectively generate an increased output of the assembly within a frequency range of the alarm tone.

Dependent claims

An assembly comprising:

an apparatus comprising:
a speaker including a diaphragm configured to generate acoustic waves defining an alarm tone;
and
a housing enclosing the speaker and including at least one first opening, the speaker being positioned within the housing such that a front chamber is between the diaphragm and the at least one first opening, wherein the acoustic waves exit from the apparatus through the at least one first opening;
and
a resonator device coupled to the housing and comprising a body having an aperture, a cavity, and at least one second opening open to atmosphere, the cavity being positioned adjacent to the housing and configured to receive the acoustic waves through the aperture, wherein the acoustic waves exit from the resonator device through the at least one second opening, and wherein the aperture, the cavity, and the at least one second opening are sized to collectively generate an increased output of the assembly having a resonance frequency within a frequency range of the alarm tone.

A method comprising:

providing an apparatus comprising a speaker and a housing, the speaker configured to generate acoustic waves defining an alarm tone, and the housing enclosing the speaker and including at least one first opening, the at least one first opening being located within the housing such that a front chamber is defined between the speaker and the at least one first opening, wherein the acoustic waves exit from the apparatus through the at least one first opening;
providing a device including a body, the body having an aperture, a cavity, and at least one second opening open to atmosphere;
and
positioning the apparatus relative to the device to enable the cavity to receive through the aperture the acoustic waves generated by the speaker and allow the acoustic waves to exit from the device through the at least one second opening, so that the aperture, the cavity and the at least one second opening collectively create, with the front chamber and the at least one first opening, a resonator that generates an increased output of the assembly within a frequency range of an output of the speaker corresponding to the alarm tone.
