Method for Generating Audible Location Alarm from Ear Level Device

An audible location alarm is generated from an ear-level device of a type comprising a memory, a microphone and a speaker, each coupled to a processor. Communication is established between the ear-level device and a companion device, the companion device having an interface, a display associated with the user interface, and an audible location alarm program stored therein. The audible location alarm program is initiated. An audible location alarm signal is transmitted to the ear-level device, thereby providing instruction to the ear-level device to broadcast an audible location alarm through the speaker of the ear level device until detection of an end event.

Sound generating device for a dual bearing reel

ActiveUS20050006512A1Easy to changeSound and resistance of a sound generating deviceReelsSound generationEngineering
A sound generating mechanism of a dual bearing reel generates sound by the rotation of a spool, and includes a serrated member, an operation member, a sounding member, a first urging member, and a second urging member. The serrated member includes projections and rotates with the spool. The operation member can come into contact and be separated from the serrated member. The sounding member is pivotably movable in accordance with movement of the operation member between a sound generation position and a release position. The first urging member urges the sounding member toward the rotational center of the serrated member when the sounding member is in the sound generation position. While the sounding member is in the sound generation position, the second urging member applies a greater urging force to the sounding member when the spool rotates in the line-releasing direction than when the spool rotates in the line-winding direction.
