DETAILED DESCRIPTION
[0021] FIG. 1 A is an exploded perspective view of an embodiment, of a vibrating unit 100. FIG. I B is. a perspective cross-sectional view of the unit 1.00. FIG. IC is a perspective view of the unit 100 without a back cover. In preferred, embodiments the unit 100 is about 3 inches in length and about 1 inch in thickness. Alternative embodiments of the unit 100 can have other dimensions. The unit 100 comprises a terminal 10, a thermally conductive back cover 20, a front cover 30. a first spider 41, a second spider 42. spider mounts 50, a plurality of stand-off connectors 43, an electromagnetic coll 60, a pole plate 71 , a magnet 72 and a yoke 73. The back cover 20 can be formed, for example, from aluminum material having a thermal conductivity of approximately 237 Watt.s/(nieter- elvin), Together, the covers 20, 30 form a housing that encloses the majority of the other components of the device 100. As discussed in the following, adhesives or any other suitable methods may be used to mechanically couple the various components together; for purposes of the following discussion a combination of adhesives and screws or the like are used, but it will be appreciated that other means may be used to hold the various components together. The term "coupled," as used herein, is intended to denote both direct and indirect connections between two or more parts or components.
(0022] The pole plate 71 , magnet 72, and yoke 73 form a motor 70 for the device 1.00, A side view of the motor 70 is shown in FIG. 2. The pole plate 71 is disposed on top of the magnet 72, and the combination is then disposed in a tubular space of the yoke 73, thereby forming an annular space 74. The width of the annular space 74 is greater than the thickness of the front portio 62 of the .magnetic coil 60. Thus, the trout portion 62 of the magnetic coil 60 may ride within the annular space 74. The components 71, 72, 73 of the motor 70 may be adhered together using a suitable adhesive. Other suitable means for coupling the components 71 , 72, 73 can be used in the alternative. The pole plate 71. substantially limits the magnetic flux in the side directions, and tightly constrains the magnetic loops. Consequently, stray magnetic .flux is kept to a .minimum. The pole plate 71 may be made, for example, from 10.10 steel with a srinc plate coating. The magnet 72 may be, for example, a neodymitira-iron-boron magnet with a nickel plate coating. The yoke 73 may be made, for example, from 1010 steel with a zinc plate coating,
(0023] As further illustrated, in FIG. 3, which is a top view of spiders 41, 42, each spider 4.1 ,
42 comprises an aperture 44 for coupling the spider 41 , 42 to an end of a corresponding stand-of connector 43, Three stand-off connectors 43 are employed, at 120 degree angles to each other with respect to the top view of the spider 41, 2. More, or less than three stand-off connectors 43 can be used in alternative embodiments. The stand-off connectors 43 may be screwed, onto the spiders 41, 42. The stand-off connectors 43 thus mechanically couple the spiders 41, 4.2 together, but keep a predefined distance between the spiders 41 , 42, which may be the height of the yoke 73 or slightly greater. The spiders 4.1 , 42 have internal regions 45 that are elastically coupled to external regions 46 by way of flexible arms 48 between the two regions 45, 46. The connectors
43 preferably are coupled to the internal regions 45. 0024} The external region 46 of each spider 41, 42 is coupled to a corresponding surface on a respective spider mount 50, by a suitable .means such as adhesive. Alternatively, each spider 41, 42 can be integrally formed with its corresponding mount 50. Each spider mount 50 includes a plurality of housing connectors 52, which align with corresponding housing connectors 52 on. the other spider mount 50 as well as on the front cover 30 and back cover 20. Screws 54 can thread through all corresponding housing connectors 52 to couple the back, housing 20, front- housing 30, and spider mounts 50. When coupled, the front housing 30 and back housing 20 form a housing fo the unit 100 that keeps out debris, facilitates mounting of the device 100, and results in acoustic effects thai are believed to increase the vibrations generated, by the moto and. allow the motor to operate at higher power levels than otherwise would be possible.
[0025} The yoke 73 is coupled to the internal region 45 of each of the first spi der 41 and the second spider 42 by a suitable means such as adhesive. For example, a hack surface of the yoke 73 is coupled to the first spider 41 , and a front surface of the yoke 73 is coupled to the second spider 42. The spiders 1 , 42 thus sandwich the motor 70, and provide an elastic suspension system that allows movement of the motor 70 along a longitudinal axis 1 to create vibration. The spiders 4.1, 42 can be made, for example, from nylon. As another example, the spiders 41, 42 can be made from nylon plastic with glass reinforcing, to provide tensile strength to the spiders 41, 42 while permitting the spiders 41 , 42 to flex.
(0026] As discussed above, the spiders 41 , 42 are coupled to respective spider mounts 50.
Each spider mount 50 h s a ring surface 51 that couples to the external regions 46 of the corresponding spider 41, 42, For example, the external, regions 46 of the spiders 41 , 42 may be adhered to the respective ring surfaces 51, Alternatively, if the spider 41, 42 is integrally formed with its corresponding mount 50, then the ring surface 51 simply defines the outer region 46 of each spieler 41. 42. Using the spiders 41 , 42, the motor 70 may thus vibrate within, and even slightly beyond, the space defined between the combined ring surfaces 51 of the spider mounts
50. The second spider 42 can also be coupled to the front cover 30 in a manner analogous to thai used for the spider mounts 50. i.e., the internal surface of the front cover 30 can have a ringed surface 32 onto which the outwardly-facing external region 46 of the second spider 42 can be attached by a suitable means such as adhesive. As noted above, the -front cover 30 can also be coupled to the spider mounts 50 and the back cover 20 via screws 54. Also, as illustrated in P G. IB, the spiders mounts 50 can be configured with corresponding tongue-and-groove geometries or similar mechanical engaging shapes, such as pins and recesses or the like, so that each spider mount 50 -mechanically engages and locks with the other spider mount 50.
|'Θ027] A rear portion 61 of the electromagnetic coil 60 is coupled to the back cover 20, such as with adheslves, A. terminal 10 has wires that extend ftom the front cover 30 and are electrically connected to the electromagnetic coil. 60. It will he appreciated, however, that any suitable electrical connector may be used to provide power to the electromagnetic coil 60. The first spider 41 has a central opening 47 through which the electromagnetic coil 60 passes to connect with the back cover 20. As discussed above, the front end 62 of the electromagnetic coil 60 rides within the annular space 74 of the motor 70. The hack cover 20 supports the electromagnetic coil 60 assembly and is directly thermally coupled to the electromagnetic coil 60. Additionally; because the back cover 20 is made of thermally conductive metal, it serves as both a heat sink and a radiator for the heat generated by the electromagnetic coil assembly 60. The front cover 30 prevents external objects from getting inside and blocking the vibrating motor 70, but includes a plurality of apertures 34 sized, to permit the movement of air into and out of the device 100. The front cover 30 .may be made from polycarbonate materials. As noted earlier, the back cover 20 is also coupled to the spider mounts 50 by a suitable means such as screws 54, and may also he coupled to the external region 46 of the first spider 41 by a suitable means such as adhesives.
[O029J The following points may be noted in vie w of the abo ve- described structure of the vibrating unit 100. First, the front cover 30 and the back cover 20 are rigidly connected to each other and the spider mounts 50. Similarly, the external regions 46 of the spiders 41, 42 are rigidly connected to their respective spider mounts 50, and hence are rigidly connected to the front cover
30 and the back cover .20. Similarly, the eiectromaanetic coil 60 is riaidi.v connected to the back. cover 20 by way of its rear portion 61, and hence the electromagnetic coil 60 is substantiall rigidl connected to the spider mounts 50, apart from some slight ilex, that may b imparted b the back portion 61 due to the mechanical limits of the materials used; this flex can kept to a minimum. The motor 70, on the other hand, is elastically connected to the spider mounts 50 by way of the interna! regions 45 of the spiders 41 , 42. Hence, whereas the majority of the component's of the device 100 are rigidly connected to each other, the motor 70 e!astieally rides within the spider mounts 50 on the suspension system provided by the spiders 41 , 42. The motor 70 and the electromagnetic coil 60 electromagnetieally couple with each other to drive the motor 70 to vibrate within the spider mounts 50. Further, during operations, because the back cover 20 is made of a thermally conductive metal, such as aluminum, or any other suitable thermally conductive material, heat generated by the electromagnetic coil 60 is rapidly conducted to the back cover 20 and radiated away, thereby cooling the unit 100. The back cover 20 thus serves to both protect the motor 70 from dust and debris and to keep the unit 1 0 cool
[0030] The unit 100 is able to accept low power signals to provide the desired vibration; for example, the input power signal may be a low-frequency 2.5 volt sine wave. In preferred embodiments the electromagnetic coil 60 has a D.C. resistance of 4, 1 ohms, .+-.5%. The electromagnetic coil 60 may have a coil with a Kapton bobbin and- a kraf belt. The coil may be wound with a single wire that creates 4 layers with, for example, 66 turns on each layer. The electromagnetic coil 60 provides a magnetic force suitable to move the vibrating motor 70,
|'O03T] The vibrating motor 70 employs complete magnetic loops. The electromagnetic coil 60 is positioned such that the magnetic in the longitudinal direction (indicated b the arrow 1) passes through the motor 70. When a signal powers the electromagnetic coil 60, the electromagnetic coil 60 generates a magnetic force on the vibrating motor 70 and moves the vibrating motor 70 in and out along the annular space 74. The spiders 41. 42 hold, the vibrating motor 70 and also provide a resilient force to bring the vibrating motor 70 back to an initial position when the signal is gone. The spider mounts 50 hold the spiders 41 , 42 as a suspension system and couple to the housing provided by the back 20 and front 30 covers. When a continuous, oscillating signal drives the electromagnetic coil 60, the signal forces the vibrating motor 70 to move back and forth. The spiders 4 L 42 pass such movement to the housing formed by the covers 20, 30, and cause the housing to move in the other direction. The housing thereb provides a convenient means .for mounting the device 1 0 wherebv vibrations aenerated by the device 1.00 can be transferred to the structure surrounding the device 1 0. 0032} The rapid movements of the vibrating motor 70 also force air in and out of the housing via the apertures or opening's 34 in the front cover 30, which causes an additional vibration effect along the longitudinal direction 1 , More specifically, the back and forth movement of the vibrating motor 70 within the housing pumps air into and out of the housing via the openings 34. The openings 34 can be sized so that the openings restrict the airflow, thereby causing back-pressure to build up within the housing. The back-pressore is believed to increase the reactive force generated between the vibrating motor 70 and the housing, thereby increasing the overall level of vibratio generated by the device 100.
|0033'j Moreover, it is believed that the back-pressure within the housing helps to dampen or reduce the maximum excursion of the vibrating motor 70 in relation to the electromagnetic coil 60. Thus, the device 100 can operate at relatively high power levels, and can thereby generate higher vibration levels, without: damage to the vibrating motor 70» electromagnetic coil 60, or other components caused by excessive excursion of the vibrating motor 70. For example, it is believed that, embodiments of the device 100 can operate without damage at a power input of approximately five Watts, while comparable devices without a housing are limited to approximately three Watts of input power, and fail at a power input of approximately five Watts.
109 4] The housing formed by the covers 20, 30 also prevents external objects from moving into the unit 100, thereby preventing jamming of the motor 70 while also allow ing air to be pumped in and out smoothly, and simultaneously cools the unit 100 via conductive and radiative effects of the back cover 20.
10035] The above-described vibrating device 100 provides a compact, lightweight and energy-efficient source of highly directional, vibratory energy, vibrating at about 50 Hz or any low frequency (such as less than 100 Hz) and requiring very low power signals (such as 2.5 Watts at 0.6 amp). Moreover, because of the design of the vibrating motor 70, there is almost, no electromagnetic interference with other equipment. As such, the embodiments of the vibrating device 100 are ideally suited for certain environments with requirements of low weight, low power, high power efficiency, and low electromagnetic interference, such as hospitals, aircraft and the like.
{0036] A .motor substantially similar to the motor 70 constructed and evaluated, in particular, an aceelerometer was mounted on the top of the motor, and the motor was operated using an AC (alternating current) voltage input of approximately 3.5 'Volt mis (root mean, square) at approximately 55 hertz. The maximum vibration generated by the motor was measured by the aceelerometer as approximately 7.6 G (unit of acceleration, caused by gravity). A conventional motor of comparable size was operated using substantially the same voltage, and an aceelerometer mounted on top of the conventional motor measured the maximum vibration level as approximately 6.4 G mis. Thus, the motor constructed in accordance with the inventive concepts disclosed herein was approximately 20 percent more efficient at generating vibrations than the conventional motor.
