A speaker box for a sport utility vehicle. The speaker box is pivotally mounted to the sports bar of the vehicle and can be selectively pivoted relative to the bar to a plurality of positions. In one position, the sound from the speakers of the speaker box is directed downwardly as in convention designs. However, unlike conventional designs, the speaker box and its sound can also be directed rearwardly of the vehicle for parties and other gatherings such as at campsites or on the beach. Further, the speaker box and its sound can be directed slightly forward toward the front of the vehicle if desired. In doing so, a saddle or cutout is provided in the middle of the speaker box so as not to unduly inhibit the driver's vision through the rear view mirror.

A speaker mounting assembly for use on a boat. The assembly consists of a rigid elongated speaker support bracket on which two interfacing boat engaging members are fixed opposite the speaker. The boat engaging members have a hole through their mid portion and are pivotally joined together each of their sides with a component of the boat, such as a rail, compressed between them. At their other side these two boat engaging members are fixed to the boat by a through bolt extending through both members. At the upper portion of one of the engaging members is a lever arm having an internally threaded hole that fits on the top of the through bolt and, when compressed, is used to retain the members to the boat. Alternately, the lever arm may be used to adjust the compressive force of the boat engaging members with respect to the engaged boat component on which mounted. By reducing the compressive force by turning the lever arm, the upper boating engaging member may be pivoted backwards and released thus releasing the speaker support assembly from the boat for storage and safe keeping. Provisions is also made for the side adjustment of the speaker's mounting bracket.

An aesthetically pleasing rear window protector for pickup trucks is made up of a main arcuate member and one or several smaller arcuate members that are welded at their ends to the main member and to each other to form any of various alternative arrangements. The rear window protector is used to protect the occupants of the truck from very large moving objects, such as a lawn mower, that might otherwise cause harm when the vehicle comes to a sudden stop.

A sound reproduction unit comprises a central, head receiving portion and opposite first and second ends. The first and second ends have opposed front and back surfaces. A first acoustic transducer is mounted within the first end and a second acoustic transducer is mounted within the second end. First, second, third and fourth acoustically substantially transparent pathways are provided between the first transducer and the front surface of the first end, the first transducer and the back surface of the first end, the second transducer and the front surface of the second end, and between the second transducer and the back surface of the second end, respectively.

A seatback audio system having one or more speakers mounted in a surface of a seatback or a headrest. The speakers may be separated by a sound barrier to reduce cross-talk between the speakers. The surface may have a concave area where the speakers and the sound barrier are mounted. Alternatively, the surface may have two concave areas, and one speaker may be mounted in each concave area. The system may include a manual or an automated positioning system for one or both of the speakers. The system may also include a soft-cell waveguide having a plurality of tubes to direct the sound from one or both of the speakers. The seatback may include a backrest and a removable headrest, each including an electrical connector, where the one or more speakers are mounted to the headrest and the electrical connectors form a circuit when the headrest is mounted to the backrest.
