- SWITCHING APPARATUS FOR SINGLE BUTTON HAND MICROPHONE Inventors: I John Stephen Coenen; Ronald Eugene ll-Iunt, both of Austin, Tex.
- a microphone switching apparatus for operating a recorder.
- the apparatus is incorporated into a hand microphone housing having a speaker, a microphone element, and an opening through which a control button for the apparatus extends.
- the apparatus is generally made up of a multi-region magnet movable along a path relative to a number of reed switches. Switching positions he along the path which is defined by a slot in the apparatus frame corresponding to the opening in the housing.
- the control button is connected to a bolt which in turn' is connected to the magnet. Movement of the button to the various switching positions will result in a combination of the reed switches being picked and dropped by the magnet. The picking and dropping of the reed switches will provide operating signals to the recorder.
- control button at two of the switching positions requires operator control in that if the operator releases the button. it will spring back to a previous position. Springs indirectly acting against the magnet cause the button to spring back to the previous position. As to the remaining positions, springs also indirectly act against the magnet, but latching means will maintain the button in place in the absence of operator control.
- the microphone shown and claimed in'this patent has a single control button movable into three working positionsfor connecting the recorder for recording, reproducing, and repeating. There is also a rest position for switching the recorder off.
- the microphone housing In the microphone housing is an opening having guideslots radiating from a center which corresponds to the rest position.
- the guide slots radiating from the center are angularly spaced and correspond to the working positions.
- the control button is directly shiftable from the rest position into any one of the radially extending guide slots.
- a recorder By incorporating the switching apparatus of this invention into a microphone housing, a recorder can be reliably and conveniently operated with a single control button.
- the apparatus is primarily made up'of a multiregion magnet and a. number of associated reed switches.
- the multi-region magnet is positionable relative to the reed switches upon manipulation of the control button in a slot along which are located six switch or recorder control positions.
- the slot in general is arcuate in shape and has two oppositely and spaced radiating portions. Positioning the control button at any switch position along the slot will result in a combination of the reed switches being picked and dropped. The picking and dropping of the reed switches will provide signals which are'used for operating the-recorder.
- the apparatus is structured such that four of the six control positions are stable. That is, once the control button is in one of these four positions, it will remain there until shifted by the operator. The control button must be held in'the other two positions and will spring back to a previous position upon release.
- FIG. ll there is shown a single button hand microphone having a control cord which is connectable to a recorder.
- FIG. 3 there is shown a away, of the switching apparatus.
- FIG. 4 there is shown a side view of the switching apparatus.
- FIG. 5 there are shown the magnet and reed switches when the control button is positioned along the control slot in a stop position.
- FIG. 6 are illustrated the magnet and reed switches when the control button is in a record position.
- FIG. 8 are illustrated the magnet and reed switches when the control button is positioned along the control slot in a review position.
- FIG. 9 are illustrated themagnet and reed switches when the control button is in a listen position.
- Microphone 50 is connectable along a control cord 49 to a recorder (not shown), and is made up of a housing 17 having openings 211, 40, and 48. Within housing 17 and communicating with openings 21 is a speaker. Also, within housing 17 and communicating with opening 48 is a microphone element. Opening 40 is a slot within which a bolt 18 is movable upon movement of integral control button 29. Movement of control button 29 to the positions instruction, record, stop, off, listen, and review will result in signals being applied along cord 49 for control and operation of the recorder. These signals are effected by the switching apparatus described below.
- FIG. 2 wherein there is shown an exploded view of the multi-position switching apparatus of this invention. Reference is also made to the plan and side views shown in FIGS. 3 and 4.
- This apparatus is incorporated into housing 17 of microphone 50.
- a bolt 18 extends through both slot 40 in housing 17 and a corresponding slot 23 in a main frame 16, and is fixedly secured to a carrier 28.
- a shifting block 6 is also secured to carrier 28 and has pins 20 which are fixed in openings24 in an activatingmechanism generally designated by reference numeral 30.
- Activating mechanism 30 is made up of 1) a magnetic member I carried by a plate 2, and 2) a U-shaped resilient detent member 4 bonded in the vicinity of openings 67 to a ferro-magnetizable spring support and base plan view, partially broken 5.
- Block 6 is slideably fitted between sides 71 and 72 of base 5.
- Base has a post 68 for maintaining a spring 3.
- Spaced from and in communicating relationship with magnetic member 1 is a card 22 carrying a number of reed switches such as 37.
- Main frame 16 has pivot post on which openings 67 in member 4 and base 5 are fitted, and about which mechanism 30 is rotatable. As illustrated, pivot 15 is displaced from arcuate-shaped slot 23 which has oppositely and spaced radiating portions (INST and OFF) opening therein and extending along radii extending from said pivot. Main frame 16 also carries restraints l1 and 12 which are rotatable about posts 57 and 58 and spring biased in the position shown (FIG. 3) by springs 13 and 14, respectively. Also, main frame 16 carries table 9 under which the upper portions of carrier 28 and base 5 are fitted. As can be seen more clearly in referring specifically to FIG. 3, the upper portion of base 5 has a detent finger 19.
- magnetic member 1 is biased in the neutral rotational position by rotatable restraints l1 and 12 (rerier 28.
- carrier 28, block 6, and activating mechanism form a unit which is rotatable about pivot post 15.
- the control button-29 With block 6 in the position shown in FIG. 3, the control button-29 will be in the position shown in FIG. 1. That is, ears 51 and 52 of U-shaped member 4 are acting against hips 69 and 70 and are in contact with waist sides 74 and 75 of block 6.
- Spring 3 is biasing block 6 in an upward direction.
- magnetic member 1 is a multi-region, or multi-pole magnetic activator having polarized portions 31, 32, 33, 34, 35, and 36 for activating and deactivating reed switches 37, 38, and 39.
- each'portion, such as 31, could be a separate magnetsince the regions below each of the illustrated portions are oppositely polarized.
- the reed switches 37, 38, and 39 are simple transducers readily available and well known in the art. They are magnetically opened and closed (picked and dropped) depending on the position of a magnet relative thereto.
- hips 69 and 70 of block 6 will ride down ramps 63 and 64. This will cause ears 5] and 52 of member 4 to expand for passage therebetween of hips 69 and 70.
- Spring 3 is'a compression spring which biases hips 69 and 70 (block 6) in an upward direction, and in the position shown, against the lower portions of ears 51 and 52.
- bolt 18 is in what is labeled a stop" position, as far as the switching apparatus as a whole is considered, this is a neutral position. That is, right and left rotation of magnet l is restrained by rotatable restraints 11 and 12. For stop position 43, reed switch 38 will be closed and reed switches 37 and 39 will be open.
- FIG. 6 wherein there is shown bolt 18 in the record position 42.
- magnetic member 1 (will be moved to the right as viewed from FIG. 3 and) will be shifted to a position determined by the contact of magnet 10' and base 5.
- mechanism 30 is rotated about post 15 against restraint 12.
- the attraction of magnet 10 to base 5 is sufficient to overcome any reverse rotation of mechanism 30 under the influence of restraint l2 and spring 14.
- reed switches 37 and 38 will be closed and reed switch 39 will be open.
- button 29 and bolt 18 are moved to the off position 46.
- the distinction between stop and off can be for purposes of turning off a continually running, clutch engageable drive motor. That is, mov ing button 29 to the off position will cause the motor to be turned off, and moving button 29 to the stop" position will cause disengagement of a drive clutch.
- bolt 18 In order to reposition bolt 18 from a position remote from, and on the opposite side of position 43, bolt 18 must be moved through position 43. As pointed out above, the position of the elements in FIG. 3 corresponds to bolt 18 being in position 43. Upon moving bolt 18 to position 46, block 6 is radially translated or switches being closed.
- the above reference to arecorder is meant to include'any recording and reproducing apparatus capable of performing such operations as recording, playing back, and backspacing.
- a dictator can operate and control the recorder by holding the above described microphone in the palm of a hand and manipulating the control button with a thumb. The picking and dropping of the combination of reed switches upon manipulation of the control button will effect connection of the speaker and microphone element to the recorder, and
- the multi-region magnet is positionable relative to the reed switches upon manipulation of the control button in a slot along which are located six switch or recorder control positions.
- the slot in general is arcuate in shape and has two oppositely and spaced radiating portions. Positioning the control button at any switch position along the slot will result in a combination of the reed switches being picked and dropped. The picking and dropping of the reed switches will provide signals which areused for operating the recorder.
- the apparatus is structured such that four of the six control positions are stable. That is, once the control button is in one of these four positions, it will remain there until shifted to another position by the operator. The control button must be held in the other two positions and will spring back to a previous position upon release.
