ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to acoustic devices and, more specifically, to acoustic adapter devices for use with personal computers and other electronic devices with a line-in input.
The present invention incorporates a 3.5 mm stereo male connector with an integral microphone and a 3.5 mm stereo female connector input. This combination adapter allows the user to plug into a line-in input device, enabling the use of a microphone and provide means to connect another line-in connection through the 3.5 mm female connector.
The present invention is particularly useful when used in conjunction with a personnel laptop computer. This combination adapter allows the user to plug into the line-in port providing means to transmit audio though the microphone while maintaining the ability to connect to another line-in device through the female connector.
The user may adjust the microphone level after plugging the microphone into the 3.5 mm stereo line-in port of the device. In addition, the user can turn down the volume of the internal speakers to prevent feedback with the microphone.
With the relatively small ridged housing, cordless structure, and simple plug-in jack style connectors of the present invention, the user can record meetings and lectures without disrupting the proceeding. The additional port also provides the user advantages over non-users in that the non-users are not able to record while using the line-in port.
The present invention 3.5 mm female input and microphone also provides the user means for video conferencing over the internet. In addition, the acoustic adapter device can be used to mix in audio while recoding video and or audio from another device.

The invention relates to electric switches of plug and socket type. The object is to provide improved means cooperating with movable element of the switch and the conducting wires normally to prevent the separation of the wires from the said element. The chief purpose of this invention is to provide means for preventing any strain upon said connection between the wire and binding post, when the pull is exerted directly upon the cord, instead of hand piece. The invention also comprises improved means for securing the hand piece or body to the movable element and improved means for securing the hand piece and movable element to the cable independently of the connection of the wires to the binding post.

A housing for an electric plug or the like is formed with an axial bore which tapers toward an inlet opening. A pressure member received in the bore for movement toward and away from the inlet opening in conforming engagement with the housing has a face which radially approaches a counter face in the bore for clamping a cable therebetween during axial movement of the pressure member toward the inlet opening. A tubular clamping member, substantially coaxial with the bore of the housing, carries threads matingly engaging threads on the pressure member about the axis. An abutment of the clamping member engages an external rim portion of the housing about the inlet opening and limits threaded movement of the clamping member inward of the bore, whereby the pressure member is moved axially toward the inlet opening, and a cable passing through the tubular clamping member into the bore of the housing is clamped between the face of the pressure member and the counter face.

A generally tubular plastic collet, which is mounted coaxially in the bore of a rigid, tubular housing, has on one end thereof a plurality of radially flexible jaws that surround one end of an electrical cord that extends into the housing bore at one end thereof. A metal tip has an externally threaded shank that is adjustably threaded into the opposite end of the housing bore, and an elongate stem portion which projects to the exterior of the housing. The tip comprises a pair of coaxially disposed conductors insulated from each other in a conventional manner, and connected in the housing to a pair of wire conductors that project from the cord. The threaded end of the tip engages and urges the collet axially toward the inlet end of the housing, thereby flexing the collet jaws radially inwardly into gripping engagement with the cord.

This invention relates to a musical instrument amplifier which is particularly useful for electric guitars. The amplifier has a rigid body for housing both the electronic system for amplifying and processing signals from the guitar and the system's power supply. An input plug connected to and projecting from the body is electrically coupled to the signal amplifying and processing system. When the plug is inserted into an output jack for an electric guitar, the body is rigidly carried by the guitar, and the guitar is operatively connected to the electrical amplifying and signal processing system without use of a loose interconnection cable. The amplifier is provided with an output jack, into which headphones are plugged to receive amplified signals from the guitar. By eliminating the conventional interconnection cable, the amplifier of the present invention can be used by musicians with increased flexibility and greater freedom of movement.

An angle connected phone plug for connection to a coaxial electrical cable without screws or other mechanisms includes a tip and wire assembly, a housing assembly and a terminal assembly all disposed coaxially along longitudinal axis of phone plug and a substantially cylindrically shaped barrel having its own longitudinal axis along which coaxial electrical cable enters phone plug. The housing assembly includes a housing base and a mating housing cap which when mated present a threaded neck at an angle to longitudinal axis Barrel is coupled to threaded neck thereby securing the housing assembly closed.
