Smoke detector with sound quality enhancement chamber

A smoke detector, comprising:

• a control board;
• a detection device for detecting smoke coupled to the control board;
• a sound producing device for producing alarms;
• a housing containing the sound producing device and the detection device;
• a sound quality enhancement chamber partially formed by an inner surface of the housing and a plate positioned within the housing between the control board and the housing and generally parallel to the control board forming a resonant element that is contained in the housing;
• and
• wherein the sound producing device is contained substantially in the sound quality enhancement chamber.

A smoke detector, comprising:

• a detection device for detecting smoke coupled to the control board;
• a housing containing a sound producing device and a detection device for detecting smoke;
• a recordable playback device for recording at least one alarm message and playing the at least one alarm message in the event the detection device detects the presence of smoke;
• and
• a sound quality enhancement chamber partially formed by an inner surface of the housing and a plate positioned within the housing between the control board and the housing and generally parallel to the control board and in communication with the sound producing device forming a resonant element for increasing the quality of sounds produced by the sound producing device.
