Detailed reference will now be made to a first potential embodiment of the disclosure, which is illustrated in FIGS. 1 through 6. The sound amplifying cell case 100 (hereinafter invention) comprises a plurality of corner brackets 101. The plurality of corner brackets 101 further comprises a first corner bracket 131, a second corner bracket 132, a third corner bracket 133 and a fourth corner bracket 134.
Each of the plurality of corner brackets 101 comprises a first leg 103, a second leg 104, a handhold 105, a first male projection 106 and a second female projection 107.
The first leg 103 is in the shape of a bar with a first groove 108 formed in it and is further defined with a first end 113. The second leg 104 is in the shape of a bar with a second groove 109 formed in it, and is further defined with a third end 115 and a fourth end 116. The first end 113 of the first leg 103 and the third end 115 of the second leg 104 are connected at a right angle 112 with a rounded corner. Extending from the fourth end 116 of the second leg 104 is the first male projection 106. The first male projection 106 is in the shape of a bar with a fourth groove 111 formed in it. The size and depth of the first groove 108, the second groove 109, and the fourth groove 111 are identical.
Extending from the second end 114 of the first leg 103 is the second female projection 107. The second female projection 107 is an extension of the first leg 103 and has a third groove 110 formed that is larger than the first groove 108. The second female projection 107 is further defined by a second end 114, which is the end distal from the first end 113. The first male projection 106 is further defined with a seventh end 125, which is joined to the fourth end 116, and an eighth end 126, which is distal from the seventh end 125. The third groove 110 is further defined with a ninth end 127, which is distal from the second end 114.
The exterior circumference of the first leg 103, second leg 104, and second female projection 107 are identical. The exterior circumference of the first male projection 106 is sized to fit into the third groove 110 of the second female projection 107. The size and depth of the first groove 108, the second groove 109, and the fourth groove 111 are identical. The size and depth of the first groove 108, the second groove 109, and the fourth groove 111 are sized to fit around the edge of the cellular phone or tablet 117 with which it is intended to be used.
The handhold 105 is a loop handle that is further defined with a fifth end 118 and a sixth end 119. The fifth end 118 is secured to the first leg 103. The sixth end 119 is secured to the second leg 104. The handhold 105 is a hollow tube with a plurality of holes 120 that are perforated on the screen 121 side of the cellular phone or tablet 117. The fifth end 118 of the handhold 105 is attached so that the inner tube 122 of the handhold 105 has access to the first groove 108 of the first leg 103 located at a first connection 123. The sixth end 119 of the handhold 105 are attached so that the inner tube 122 of the handhold 105 has access to the second groove 109 of the second leg 104 located at the second connection 124. This access allows sounds from the speaker of the cellular phone or tablet 117, which is collected and transported through the first groove 108, second groove 109 and fourth groove 111, to be routed to the handhold 105 and directed in the direction of the user through the plurality of holes 120. Directing the sound in one direction makes the cellular phone or tablet 117 sound louder than it otherwise would.
Each of the plurality of corner brackets 101 can be formed as a single piece from several materials including, but not limited to, plastic, aluminum or nitrile rubber. The first corner bracket 131, the second corner bracket 132, the third corner bracket 133 and the fourth corner bracket 134 are all made of the same material.
Detailed attention is now directed towards the first corner bracket 131 which is further defined with a third male projection 136 and a fourth female projection 137. The span from the first end 113 of the first leg 103 to the second end 114 of the fourth female projection 137 is longer than the span from the third end 115 of the second leg 104 to the fourth end 116 of the second leg 104. The span from the seventh end 125 of the third male projection 136 to the eighth end 126 of the third male projection 136 is longer than the span from the second end 114 of the fourth female projection 137 to the ninth end 127 of the fourth female projection 137.
Detailed attention is now directed towards the second corner bracket 132, which is further defined with a fifth male projection 138 and a sixth female projection 139. The span from the first end 113 of the first leg 103 to the second end 114 of the sixth female projection 139 is longer than the span from the third end 115 of the second leg 104 to the fourth end 116 of the second leg 104. The span from the seventh end 125 of the third male projection 136 to the eighth end 126 of the third male projection 136 is shorter than the span from the second end 114 of the fourth female projection 137 to the ninth end 127 of the fourth female projection 137. The span from the second end 114 of the sixth female projection 139 to the ninth end 127 of the sixth female projection 139 is longer than the span from the seventh end 125 of the third male projection 136 to the eighth end 126 of the third male projection 136.
Detailed attention is now directed towards the third corner bracket 133 which is further defined with a seventh male projection 140 and an eighth female projection 141. The third corner bracket 133 is identical to the first corner bracket 131.
Detailed attention is now directed towards the fourth corner bracket 134 which is further defined with a ninth male projection 142 and a tenth female projection 143. The fourth corner bracket 134 is identical to the second corner bracket 132.
To attach the invention 100 to the cellular phone or tablet 117 being protected, the third male projection 136 is inserted into the sixth female projection 139, the fifth male projection 138 is inserted into the eighth female projection 141, the seventh male projection 140 is inserted into the tenth female projection 143 and the ninth male projection 142 is inserted into the fourth female projection 137. The relative positions of third male projection 136 and the sixth female projection 139, the fifth male projection 138 and the eighth female projection 141, the seventh male projection 140 and the tenth female projection 143, and the ninth male projection 142 and the fourth female projection 137 are adjusted until the grooves are fit into place.
With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention described above and in FIGS. 1 through 6, include variations in size, materials, shape, form, function, and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention.
