Resilient strap 102 has opposed clamping ends 122 featuring respective semi-cylindrical protrusions 114 that fit conformally into respective semi-cylindrical grooves 116 when installed. The internal surface 110 of resilient strap 102 engages the pipe or similar support in operation. Outer surface 120 is generally exposed to view and the environment. The clamp base 104 has a through-bore 704 (see FIG. 7) to which opposing through-bores 702 (see FIG. 7) in each opposed clamping end 122 align to receive clamp bolt 106 which is tightened using nut 108 to secure the speaker bracket 100 to a pipe, handle bar, or similar support. Adjacent to either side of the semi-cylinder grooves 116 and protrusions 114, flat surfaces of the clamping ends 122 abut flat surfaces of the clamp base 104 when the strap 102 is installed.
The clamp base 104 also has threaded fastener holes 112 to assist in fastening the speaker bracket 100 to a speaker 204 (see FIG. 2) optionally using adapter 302 (see FIG. 3). Speaker bracket 100 is preferably made of metal. In various other embodiments, other materials may be used.
FIG. 2 is a rear perspective view illustrating the exemplary embodiment of the speaker bracket 100 of FIG. 1 fully installed, according to a preferred embodiment of the present invention. Speaker bracket 100 couples speaker 204 to support 202. Support 202 may be stage rigging, a tow bar on a wake boat, or any circular cylindrical extent of any object. In other embodiments, the support 202 may be of various cross-sectional shapes, with strap 102 conformally shaped to receive such support. While speaker 204 is a wake boat speaker 202, the invention is not limited to any one kind of speaker 204.
FIG. 3 is a side perspective view illustrating the exemplary embodiment of the speaker bracket 100 of FIG. 1 installed on the speaker 204 of FIG. 2, according to a preferred embodiment of the present invention. Adapter 302 is fastened to the bottom of clamp base 104 as will be described in further detail in regard to FIG.7. Adaptor 302 rests on platform 306 and has arcuate slots 308 (one visible in this view) through which fasteners 304 enter into threaded fastener receivers inside speaker 204 (not shown). In other embodiments, fasteners 304 may be positioned differently in slot 308, depending on the arrangement of the fastener receivers in other speakers 204. Fastening may be to the loudspeaker housing, the loudspeaker frame, and/or the loudspeaker. Speaker 204 has a water-resistant grommet 310 in an opening in platform 306 through which audio signal wires 312 extend.

Yet even larger straps may be used with larger clamp bases 104, where the larger clamp base 104 shape is the same shape as illustrated for clamp base 104.
FIG. 11 is a front elevation view illustrating a second exemplary embodiment of a dual speaker bracket 1100, according to a preferred embodiment of the present invention. Dual speaker bracket 1100 includes a speaker strap 1150. Speaker bracket 1100 begins similarly to speaker bracket 100, with strap 102, strap ends 122, and clamp base 1104, which is like clamp base 104, but with legs 1120 that end in rounded portions 1122, as shown. Legs 1120 have pivot bores 1210 (see FIG. 12) aligned with a pivot block bore 1212 (see FIG. 12) through pivot block 1124 through which pivot bolt 1132 extends to engage pivot nut 1134. Pivot bolt 1132 can be loosened to allow pivoting and tightened to lock the joint into position. Pivot block 1124 has a semi-cylindrical portion 1128, a screw divot 1126 in the semi-cylindrical portion 1128, and flat-sided portion 1130 extending from the semi-cylindrical portion 1128. As will be described more fully below, pivot block 1124 rotates relative to strap base 1136 about what would be a vertical axis in the plane of FIG. 11, such as the axis of screw 1206. Pivot head 1146 in recess 1148 rotates with pivot block 1124. Pivot block 1124 also rotates about pivot bolt 1132, creating a doubly articulated joint. Strap base 1136 extends into speaker strap 1138 and to strap end 1140. Strap end 1140 has a strap end bore 1218 (see FIG. 12) that aligns to a threaded bore 1220 (see FIG. 12) in strap base 1136 to receive second clamping bolt 1144 with head 1142.
FIG. 12 is a front cross-sectional elevation view illustrating the second exemplary embodiment of the dual speaker bracket 1100 of FIG. 11, according to a preferred embodiment of the present invention. Second clamping bolt 1144 clamps strap end 1140 to strap base 1136. Head 1146 is the head of a smooth cylinder 1208 into which a screw 1206 (or similarly effective fastener) captive in pivot block 1124, is fixedly threaded. Rotation of the smooth cylinder 1208 may be prevented by advancing set screw 1204 in bore 1202 in strap base 1136, as shown. Smooth cylinder 1208 is inserted into a complimentary vertical cavity 1216, or strap base through-bore 1216, in strap base 1136 during assembly, and captive screw 1206 fastens pivot block 1124 to smooth cylinder 1208 for concurrent rotational adjustment. Screw 1206 is made captive in that it is first inserted into pivot block through a bore 1214 leading from screw divot 1126, is tightened in smooth cylinder 1208, and then pivot bolt 1132 is inserted through legs 1120 and pivot block 1124, thereby capturing screw 1206.
