A flip style cellular telephone includes a main housing, a microphone mounted in the main housing and a flip, pivotably mounted to the main housing by a hinge. The flip is formed with an acoustic pipe on a peripheral edge of the flip. The acoustic pipe extends from the free end to the hinged end of the flip, and includes a plurality of holes for a sound inlet at the free end of the flip. The hinge is hollow, and the acoustic pipe connects with the microphone through the hollow hinge. Sound of the user's voice is carried by the acoustic pipe from the inlet to the microphone. The acoustic pipe advantageously only minimally changes the profile and aesthetics of the telephone.

A microelectric module including a circuit substrate having one or more covers or electromagnetic shields disposed thereon. To secure the covers or electromagnetic shields to the circuit substrate, and provide an electrical contact with an underlying ground pattern, a thin plastic film is extended over the covers or electromagnetic shields and the circuit substrate. This film is subjected to heat, causing it to shrink and effectively provide a controlled force that acts to hold and lock the covers or electromagnetic shields to the circuit substrate. Thus the heat-shrunk film mechanically secures the covers or electromagnetic shields to the circuit substrate and at the same time seals the microelectric module formed.

Handheld radiotelephones are provided with battery packs that facilitate the transmission of a person's voice to internally mounted microphones. A radiotelephone housing end portion is provided with an aperture that is in acoustic communication with an internally mounted microphone. A passageway extends through a battery pack from a sound inlet in a front portion thereof to a sound outlet in an end portion thereof. The sound outlet is in acoustic communication with the aperture when the battery pack is removably secured to the housing end. Accordingly, the sound inlet is in acoustic communication with the microphone via the passageway.

A coplanar antenna connector which interconnects an antenna and a printed circuit board of a portable radiotelephone is described. In particular, the antenna connector includes an antenna connector conductor strip having opposing first and second ends adapted for transmitting a radiotelephone signal from a source to an antenna or from an antenna to a receiver. The connector also includes at least one antenna connector ground strip having first and second opposing ends adapted for transmitting a radiotelephone signal. The at least one antenna connector ground strip and the antenna connector conductor strip are held in coplanar alignment, preferably by a nonconducting carrier ribbon. Each of the at least one antenna connector ground strips and the antenna connector conductor strip are spaced-apart and define a gap therebetween. The flexible antenna connector provides an easy, cost effective connection between the antenna and the printed circuit board in a manner which minimizes the amount of printed circuit board space needed therefor. The connector is also easily adaptable for use with retractable antennas. Also described are radiotelephones, portable radiotelephone antenna assemblies, and related radiotelephone assembly methods employing a flexible antenna connector.

Electromagnetic shielding devices are provided with walls having a pair of opposing, generally parallel side faces that terminate at a tapered end portion. Each tapered end portion is configured to be surface mounted to a respective conductive portion (e.g., mounting pad) of an electronic substrate via a pair of solder fillets. The tapered end portion of each wall includes a pair of elongate end faces symmetrical about a plane that is generally parallel to, and equidistant between, the wall side faces. The end faces define a pair of elongated cavities with respect to a PCB that are configured to receive the solder fillets.

Edge interface electrical connectors 75 and configurations for electrical devices such as radiotelephones position electrical contacts 55 on a lateral or edge surface of a printed circuit board 110, 110A and employ spring contacts 74 to interconnect other components such as batteries 60 or other accessories therewith.

A cellular telephone for improved transmission includes a housing body that is shaped with a curvature so that a front face of the body is convex. A flip pivotally mounted to a bottom end of the body is correspondingly shaped so that the flip is pivotable between a closed position covering the front face, and an open position extended from the body. An antenna is mounted to the top end of the body and extends therefrom. When the flip is in the open position, the body and flip define an S-shaped profile which results in the antenna being spaced away from and oriented away from the user which avoids interference with the user for better transmission.

An apparatus for testing of circuitry located on a printed circuit board without placing test point pads on the surface of the printed circuit boards as is currently done. Test point pads which are constructed of a conductive material are placed on the edge of a manufacturing panel holding the printed circuit boards in place during the manufacturing and testing process. The pressure point pads, when located on the edge of a manufacturing panel, do not face design pressures to reduce their size and number in an effort to preserve space as do pressure point pads which are located on the surface of printed circuit boards. The larger pressure point pads of the current invention are electrically connected to the test circuitry on the printed circuit board via router tabs. These router tabs are constructed of printed circuit board material and hold the printed circuit board attached to the manufacturing panel during the manufacturing and testing process.

A battery is provided for an electronic device that includes contacts on inside and outside surfaces of the battery enabling additional batteries to be stacked on the battery in use. With respect to a cellular phone, this arrangement enables an operator to add additional talk time without requiring the operator to terminate a call. The battery casing is shaped corresponding to the electronic device to maximize battery capacity while minimizing size. In one arrangement, the male terminals that are not in use are retracted within the battery casing, and a sensor assembly senses the attachment of an auxiliary battery and extends the male contacts outside of the battery casing. The configuration allows greater choice of battery capacity and also permits the addition of more batteries as one is depleted.

An audio input for flip phones wherein the acoustical openings currently located on the inside edge of the flip are relocated to the outer edge of the flip. The relocation of the openings allow sound to enter the flip through the openings unobstructed by the face of the telephone user while the phone is in use. The relocation of the openings further allowing for enhanced pick up of ambient noise while the telephone flip is in the closed position.

The present invention places a semi-lossy gasket between a printed circuit board ground pad ring and a metal shield can for shielding electronic components and circuitry which generate electromagnetic radiation. The present invention also provides a variety of means for aligning and mounting the shield can and gasket to the printed circuit board. Guide pins extending from the shield can extend through apertures in the printed circuit board for aligning the shield can to the printed circuit board. The guide pins can be bent or soldered to the printed circuit board and can also include a hooked end for latching on to the printed circuit board.
