Abstract
Abstract Enclosure and mounting for a loudspeaker is combined with enclosure and mounting for an ionization sensor, a printed circuit board and a battery. The battery and portions of the front portion and rear portion of the device intersect with the other portions in such fashion that no fasteners such as screws, rivets, adhesive or the like are utilized to retain these portions in assembled relation.

Claim 4
Dependent Claim
143 words
The device of claim 1 wherein: said rear bracket portion is provided with a plurality of outwardly extending resiliently deformable memberS, and said base portion has a plurality of rearwardly extending walls equal in number to the number of said resiliently deformable members extending outwardly from said rear bracket portion, and each of said walls is provided with a recess in which is received one of said resiliently deformable members extending outwardly from said rear bracket portion, and each of said recesses is extended laterally with respect to each of said resiliently deformable members extending outwardly from said rear bracket portion which is received therein, whereby said base portion may be removed from said rear bracket portion by withdrawing said base portion away from said rear bracket and thereby resiliently deforming said resiliently deformable members with which said rear bracket portion is provided.
Claim 5
Dependent Claim
109 words
The device of claim 1 wherein means are provided to receive a longitudinally extended battery in said device, said means comprising the combination of: a plurality of extending members extending from one side of said speaker bracket portion to abut a side of said battery, two portions extending upwardly from said base portion to support said battery near each of its ends and to restrict its longitudinal movement, and a plurality of resiliently deformable members extending upwardly from said base portion to contact a side of said battery, said battery being removable by withdrawing it laterally and resiliently deforming said resiliently deformable members which extend from said base portion.
Claim 6
Dependent Claim
145 words
The device of claim 4 wherein: said rear bracket portion is provided with a plurality of outwardly extending resiliently deformable members, and said base portion has a plurality of rearwardly extending walls equal in number to the number of said resiliently deformable members extending outwardly from said rear bracket portion, and each of said walls is provided with a recess in which is received one of said resiliently deformable members extending outwardly from said rear bracket portion, and each of said recesses is extended laterally with respect to each of said resiliently deformable members extending outwardly from said rear bracket portion which is received therein, whereby said base portion may be removed from said rear bracket portion by rotating said base portion with respect to said rear bracket portion and thereby resiliently deforming said resiliently deformable members with which said rear bracket portion is provided.
