DETAILED SPECIFICATION
An ornamental sound module 10 for a balloon 46 in its first embodiment is shown in FIGS. 1 through 4.
The module 10 has a raised star ornamental front portion 12 suitably made of plastic having a peripheral lip or flange 14 therearound and a front face 16 which suitably may be subject to further artistic renderings. The backer board 18 is suitably made of light weight styrofoam and has a face 20. The peripheral edge 22 of the backer board 18 suitably has adhesive thereon for securing to the lip or flange 14 of the plastic raised star 12. A central aperture 24 is provided having a buzzer support rim 26 therearound. By adhering the raised star 12 and backer board 18 at their peripheries 14 and 22, housing 28 is created. Piezoelectric buzzer 30 is suitably constructed of a metal disc 32 of relative large diameter having a peripheral edge 34 therearound. Smaller crystal or ceramic plates 36 are fixed to opposite sides of the metal disc 32 and are suitably connected by appropriate wiring 38.
Within housing 28 is a circuit board 40 which suitably supports a sound chip, a switch, a battery and wires 42 for connection to the wires 38 of buzzer 30. The switch may be mechanical, electronic or a motion detector.
The ornamental sound module 10 maybe adhered to a metalized nylon film balloon 46, or other inflated object suitably made of clear plastic latex or vinyl, by adhesive on face 20.
Referring to FIGS. 5 through 8 the second embodiment of the ornamental sound module 50 for a balloon 86 may be viewed.
The sound module 50 has a raised star front portion 52 with a peripheral lip or flange 54 and a front face 56 which may further be ornamentally decorated. In this embodiment, the backer board 58 is a second raised star like portion suitably made of plastic having a face 60. A peripheral edge 62 of the backer board 58 is suitably adhered to the peripheral flange 54 of the front raised star portion 52 thereby creating housing 68 therewithin. Backer board 58 suitably has a central recess 64 which supports a plastic spacer 66 which may be adhered thereat.
A piezoelectric buzzer 70 suitably has a metal disc 72 with a peripheral edge 74 and crystal or ceramic plates 76 suitably connected by wiring 78. The buzzer 70 is adhered to the plastic spacer 66 which is adhered within the central recess 64. Within the housing is a circuit board 80 suitably supporting a sound chip, switch, battery and wires 82 to be connected to the buzzer 70. Adhesive maybe applied to the backer board 58 at face 60 with a film protecting the adhesive quality until use. At the appropriate time, the liner is removed and the ornamental sound module 54 may be adhered to a metalized nylon film balloon or other clear plastic, latex or other vinyl inflatable objects.
A first embodiment of a magnetic speaker sound module 55 attached to a balloon is shown in FIG. 9.
As in the previous embodiment of the ornamental sound module, backer board 58 is suitably adhered to the peripheral flange 54 of the front raised star portion 52 thereby creating housing 68 therewithin. The sound module 10, 55 may preferably comprise, within housing 68, a magnetic speaker 90 attached suitably by wires 92 to a power source 94. The backer board 58 has an aperture 96 therethrough into the housing 68 with a support rim 98 for the magnetic speaker. The magnetic speaker 90 is positioned so that is adjacent to the aperture 96, with sound from the magnetic speaker 90 being transmitted through the aperture 96. When the sound module 55 is adhered to the balloon 86, a gap or air column 100 remains between the aperture 96 and the balloon 86. In the first embodiment, the balloon 86 is constructed of two pieces 86a, 86b of film of unequal weight. The sound module 55 is attached to side 86a by adhesive. In order for the balloon 86 to float upright with the sound module 55 attached to side 86a, side 86b must have a greater film weight than side 86a. 
For example, but without limitation, Applicant has found that a desired film weight for side 86a is about 12.61 grams while a desired film weight for side 86b is about 18.5 grams. These weights can be achieved by manufacturing side 86a from 40 gauge metallized nylon film of 7.9 grams extruded weight. The film weighs about 152 milligrams per 9.375 square inches. With approximately 778 square inches of surface area, side 86a will have a weight of approximately 12.6 grams. Side 86b may be suitably constructed of 48 gauge metallized nylon to yield a weight of about 18.5 grams. The total weight of the two sides 86a, 86b will thus be about 31.1 grams.
In contrast, a typical balloon manufactured with 40 gauge film on both sides will have a weight of about 25.23 grams. Such a balloon, having a volume of helium with an overall lift of 70.23 grams will lift the 25.23 gram film with an overall lift of (70.23-25.23) or 45 grams.
The difference between the film weights of a standard balloon and of the balloon of FIG. 9 is (31.1-25.2) or 5.9 grams. This means that compared to the standard balloon, the balloon of FIG. 9 will have an overall lift of (45-5.9) or 39.1 grams. It is anticipated that the speaker module 55 will have a weight of about 25 grams, leaving a net float of (39.1-25) or 14.1 grams. This is anticipated to keep the balloon 86 floating vertically.
The speaker of the sound module 55 may suitably have the following characteristics:
Rated impedance (ohms): 8+−15%.
Rated (Max) Power (W): 0.25 (0.5).
Resonance frequency (Hz): 0-5000.
Sound pressure level (db): 85+−−3.
Magnet (g): 1.1
Operating temperature (Degree C.): −10−+40.
Applicant has further found that constructing the magnetic speaker sound module 55 with aperture 96 results in an air column 100 between the backer board 58 and the balloon 86 having a depth of about 7 to 10 mm. This air column produces significantly enhanced sound levels.
Table 1 illustrates sound testing with the sound module 55 attached to the balloon 86.
In the Table, the following notation is used:
A=12′′ away from front of device (Hand held)
B=12′′ away from back of device (Hand held)
C=12′′ away from back of balloon (Floating, center of balloon)
D=12′′ away from front of balloon (Floating, center of balloon)

A second embodiment of a magnetic speaker sound module 55 is shown in FIG. 10. The magnetic speaker sound module 55 may be as previously described in the first embodiment. However, rather than manufacturing one side of the balloon with film of a greater weight, a counterbalance 110 is used to offset the weight of the sound module 55. The counterweight 110 is positioned internally in the balloon to counteract the tip of the balloon caused by the sound module in order to bring the tip angle to an acceptable level.
Clearly, the relative position of the counterbalance 110 and its weight depends on the weight of the sound module 55. Applicant has found that the sound module 55 is preferably placed a distance D1 about 5.5 inches from the bottom of the balloon, and the counterbalance a distance D2 about 15.25 inches from the bottom of the balloon. When so placed, the weight of the counterbalance 110 depends on the weight of the sound module 55 according to the following table:
