Personal audible alarm
First Claim
1. Apparatus for a device which is to be worn in abutting contact with an ear of a user, the apparatus comprising:
- a housing adapted to be worn on the ear of the user or extending into an ear canal of the user;
a user-settable clock circuit contained within the housing for generating an output signal when a value of time maintained by the clock circuit reaches a time setpoint defined by the user, the clock circuit comprising at least one user-manipulative control, mounted on the housing and connected to the circuit, through which the user can manually program the setpoint into the circuit; and
an acoustic transducer, connected to the clock circuit and mounted within the housing, for generating, in response to the output signal, an acoustic output, the transducer being oriented in the housing such that, when the device is worn by the user, the acoustic output is directed into the ear canal;
whereby the clock circuit and acoustic transducer are integrated into the device.

Abstract
An audible alarm placed in an ear plug or hearing protection device intended to be worn by an individual user. Because the alarm of the present invention is incorporated into a ear plug or hearing protection device it can be heard by the user even in noisy conditions. The audio output of the alarm is located on the side of the earplug or hearing device which is open to or exposed to the user'"'"'s ear canal but isolated from the external environment by the remaining portion of the ear plug or hearing protection device. Thus, individuals near the user are not exposed or annoyed to the audio output of the alarm to any significant degree. In addition, because the audio output is isolated from the ambient noise of the external environment and in close proximity to the user'"'"'s ear, that output can be generated using relatively little power and heard even when there is a relatively large degree of ambient noise. For similar reasons, the alarm of the present invention is well suited for use by the hearing impaired which might require an unusually loud alarm that would be annoying to nearby individuals. The alarm of the present invention may also be used to inform a user, e.g., of waiting messages on an answering machine or of a telephone call without alerting nearby individuals to the condition, or in the case of the hearing impaired, with an audible signal that is close enough to their ear that they can hear the signal.
