Hand-held sound generating device
First Claim
1. A sound generating device, comprising:
- a body defining a first end, a second end, and an exterior, wherein the body includes a first acoustically open portion and a second acoustically open portion, wherein the first and second acoustically open portions are spaced from each other and open onto the exterior of the body, and wherein the body defines an acoustically open internal passage extending between the first and second acoustically open portions;
a speaker positioned between the first and second acoustically open portions, wherein sounds emitted by the speaker are communicated exteriorly of the body through the first and second acoustically open portions;
a sound signal generator interconnected with the speaker; and
a manually operable control arrangement interconnected with the sound signal generator and including manually operable actuator means accessible from the exterior of the body.

Abstract
A sound generator consists of a housing defining open first and second ends and an internal passage extending therebetween. A speaker is positioned within the housing, and a control arrangement including a circuit board is interconnected with the speaker. The circuit board is preferably located within the internal cavity, and a manually actuable switching arrangement is accessible from the exterior of the housing and interconnected with the circuit board for controlling the output therefrom to the speaker to control the sound generated by the speaker. In one form, the switches are accessible via a control portion formed on a wall of the housing, and in another form the switches are accessible through a movable shield member or sleeve mounted to the housing having an opening providing access to certain of the switches. Grills are positioned within the open ends of the housing, to enable sound waves to escape from both sides of the speaker, with the internal passage having a length ensuring that the emanating sound waves do not cancel each other.

12. A sound generating device, comprising:
-
a hollow tubular housing having a substantially circular side wall and defining opposite first and second acoustically open ends and an axial internal passage extending therebetween, the body having an exterior; a speaker positioned between the first and second ends; a sound signal generator interconnected with the speaker; a manually operable control arrangement interconnected with the sound signal generator and including manually operable actuator means accessible from the exterior of the body, wherein the manually operable actuator means comprises at least two radially offset switches located adjacent the side wall; and a shield member rotatably mounted to the housing and having an opening for providing access to certain of the switches dependent upon the rotational position of the shield member relative to the housing. - View Dependent Claims (13)
