Abstract: A device including a speaker and a housing, in which the speaker is configured to generate sound and includes a diaphragm and the housing encloses the speaker and includes a plurality of openings within one portion of the housing. The speaker is positioned within the housing to define a front chamber between the diaphragm and the one portion, and the plurality of openings are sized to collectively generate, with the front chamber, an increased output of the device within a frequency range of an output of the speaker corresponding to an alarm tone. Also provided are methods for assembling a device including a speaker and a housing.

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.

Abstract: A loudspeaker assembly is provided that is suitable for use with a small mobile device, the assembly utilizing a bass-reflex design to increase low frequency efficiency and decrease speaker distortion. The loudspeaker assembly utilizes a single sound port in which the sound pressure emitted by the diaphragm is combined with the sound pressure passing through the bass-reflex channel.
