Definitions

  • the invention relates to a miniaturized re ⁇ ceiver, as for a hearing aid.
  • Miniaturized receivers such as for use in hearing aids, are known. Often such receivers are designed to provide a certain frequency response characteristic to accomplish a particular result.
  • Carlson U.S. Patent No. 5,068,901
  • Accord ⁇ ingly Carlson provided a dual outlet passage hear ⁇ ing aid transducer, having a pair of elongated sound transmission tubes, which produced a high pass band.
  • This receiver was able to better assist the user at the higher frequencies of hearing i - pairment, yet which effectively eliminated low frequency transmission.
  • a low frequency sound transmission channel was provided parallel to the hearing aid. This sound transmission channel bypassed the hear ⁇ ing aid, to permit the user to directly hear low frequencies.
  • the hearing aid transducer of Carlson worked satisfactorily for many applications; however, the elongated sound transmission tubes tended to make further miniaturization of the hearing aid diffi ⁇ cult.
  • the receiver includes a housing, being for example D-shaped in cross section.
  • the D-shape configuration permits the receiver to more readily be placed in the canal portion of the hearing aid.
  • a diaphragm is provid ⁇ ed having a plurality of peripheral edges.
  • the diaphragm is disposed within the housing and de ⁇ fines first and second acoustical chambers in the housing.
  • One of the diaphragm peripheral edges is pivotally secured to the housing. This pivotable edge may also be further secured to the housing by a cement, such as an epoxy, to prevent lateral movement.
  • the remaining edges of the diaphragm are compliantly secured to the housing.
  • An electromag- netic motor including an armature, forms a portion of the housing, and means are provided for coupling the armature to the diaphragm to move the diaphragm at frequencies in accordance with an electrical signal applied to the motor.
  • First and second outlet ports extend through the housing.
  • the first outlet port is acoustically coupled to the first chamber via a tube
  • the second outlet port is acoustically coupled to the second chamber.
  • the first and second ports provide an exit path for acoustical vibrations generated as a result of diaphragm movement.
  • the first and second acousti ⁇ cal chambers cooperate to cancel low frequency acoustical waves, while generating high frequency acoustical waves at the frequencies of interest. This phenomenon is more fully explained in the above referenced Carlson patent.
  • the armature is cou ⁇ pled to the diaphragm by a compliant compound, such as compliant RTV having a durometer of 22 Shore A, or less. It is further contemplated that the receiver includes a tube disposed within the first acoustic chamber. The tube terminates substantially flush with the first port.
  • the above receiver is provided, but without the tube and the first outlet port. Accordingly, low fre ⁇ quency acoustical waves are not cancelled, and, hence, the receiver has a broad band frequency response. It is a still further aspect of the invention to combine two of the above receivers in back-to- back relationship, to provide a generally oval- shaped receiver having twice the output as a single receiver. Vibration is reduced in this , embodiment because the respective armatures move 180° out-of- phase.

  • the frequency response of the Carlson receiver had three peaks.
  • the middle peak occurred at approximately 4.5 kHz, and was a result of motor resonance.
  • the lower peak occurred at a frequency of approximately 3 kHz and was a result of the resonance of the first elongated tube in combination with the first chamber.
  • the upper peak occurred at a frequency of approximately 5.7 kHz and was a result of the resonance of the second elongated tube in combination with the second chamber.
  • Elimination of the tubes was considered as a way to permit further miniaturization of the Carlson receiver, yet this was found to degrade the overall frequency response of the receiver because it eliminated the lower and upper resonant peaks.
  • a design goal of the miniaturized receiver was to provide a lOOdB spl response at 4 kHz into a 2 cc. cavity. Accordingly, it was also considered to eliminate the second tube, thereby eliminating the upper resonant peak (5.7 kHz) out of the pass band, while also moving the first tube into the housing. Thus, it was believed that this change would main- tain the lower (3 kHz) and middle (4.5 kHz) reso ⁇ nant peaks, while permitting downsizing of the receiver.
  • the first resonant peak could be raised by reducing the effective mass of the system seen by the armature.
  • the armature bends about a point, located generally where the armature is attached to the housing.
  • the effective mass of the system seen by the armature could be reduced by attaching the diaphragm to the housing of the receiver along the edge of the diaphragm opposite the point where the armature is coupled to the diaphragm so that the diaphragm would pivot about an effectively shorter lever arm.
  • the diaphragm is driven by a drive rod coupled to the motor arma ⁇ ture.
  • the drive rod was able to flex slightly to compensate for the pivot action of the diaphragm which is pivoting about a different axis than the armature.
  • the present miniaturized receiver there was insufficient space to locate the drive rod. Accordingly, applicants have deve ⁇ loped a novel means for attaching an armature to a pivotable diaphragm, wherein the attachment is rigid along the coupled axis while being compliant along the shear axis.
  • a compact band pass receiver 10 for a hearing aid 11 ( Figure 6) is illustrated in Figures 1-4.
  • the receiver 10 is extremely compact, yet provides a commercially satisfactory band pass frequency response as shown in Figure 5.
  • the receiver 10 has a high frequency band pass charac ⁇ teristic.
  • the receiver 10 comprises an electromagnetic motor, generally designated 16, and a first housing portion 18.
  • the electromagnetic motor 16 has a second housing portion 17, a conventional coil 20, a magnet housing 22 formed of conventional nickel/iron alloy laminations 24 and two permanent magnets 26, and an armature 28.
  • the second housing portion 17 is a generally D-shaped cup, formed of conventional nickel/iron alloy and has substan ⁇ tially open 17a and closed 17b ends.
  • the armature 28 has a fixed end 28a and a free end 28b.
  • the coil 20 is disposed within the second housing por- tion 17.
  • the armature fixed end 28a is uniquely secured, as by welding, to the closed end 17b of the second housing portion 17.
  • the magnet housing 22 adjoins the substantially open end 17a of the second housing portion 17, and is secured thereto by projection welding.
  • the armature free end 28b extends out ⁇ wardly from the magnet housing 22.
  • a gap of 0.003" is provided between the armature 28 and the magnets 26.
  • the first housing portion 18 is also generally a D-shaped cup having open 18a and closed 18b ends.
  • the housing portion open end 18a adjoins the magnet housing 22 opposite the second housing portion 17, such that the armature free end 28b extends into the first housing portion 18.
  • the first housing portion 18 is also projection welded, or alterna ⁇ tively laser welded, to the magnet housing 22.
  • a supporting cup 34 (shown in phantom in Figure 2) is disposed in the housing portion 18, providing a peripheral ledge 36 circumferentially about each of four walls 34a of the acoustical housing portion 18.
  • the overall length of the receiver 10 is 0.244".
  • the overall width at the base of the receiver 10 is 0.118".
  • a generally square diaphragm 40 is provided comprising a generally rigid, aluminum paddle 42 secured to a conventional diaphragm membrane 43.
  • the membrane extends outwardly from the paddle from all four sides of the paddle, for compliant connection within the receiver housing. According to such prior art diaphragms, the diaphragm effectively pivots about the fixed end 28a of the armature 28 when acted upon by its respective armature.
  • the membrane 43 extends outwardly from three sides of the paddle 42, forming a compliant peripheral annulus 44 about the three sides.
  • the annulus 44 thus terminates at three peripheral edges 40a.
  • the annulus 44 about the three edges 40a is secured to the respective ledges 36 of the cup 34, providing a compliant connection therebetween.
  • the paddle 42 is spaced from the cup 34 along these three edges by the annulus 44, as illustrated in Figure 2a.
  • a fourth edge 4Ob of the diaphragm 40 has no annulus. Rather the paddle 42 extends to the inside edge of the cup 34, as illustrated in Figure 2b.
  • the membrane 43 extends beyond the edge of the paddle 42, to be secured to the respective ledge 36.
  • the paddle 42 is not spaced from the cup 34 by the annulus 44 along the fourth edge 40b. Accordingly, the fourth edge 40b is rigidly secured to the cup 34, rather than compliantly secured thereto.
  • the diaphragm 40 is disposed across the first housing portion 18, supported by the peripheral ledge 36 of the cup 34.
  • the diaphragm 40 defines first and second acoustical chambers, generally designated 48,50.
  • the second acoustical chamber 50 includes all air space within the electromagnetic motor 16.
  • the three sides forming the peripheral annulus 44 of the diaphragm 40 are compliantly secured to the ledge 36 by a film of 0.0005" thick ⁇ ness, such as urethane.
  • the fourth edge_ 40b of the diaphragm 40 which is generally rigid due to the coextensive paddle 42, rests along the remaining side of the edge 36. To insure that the fourth edge 40b of the diaphragm 40 remains along the remaining side of the edge 36, so as to eliminate any possible unwanted resonance, a drop or two of epoxy 51 may be applied.
  • this pivotal connection of the diaphragm 40 reduces the amplitude of the receiver output, because the pivotal diaphragm moves less air per unit motion of the armature as compared to convention complaint coupling of the diaphragm.
  • this amplitude reduction was considered a necessary tradeoff to obtain the desired frequency response.
  • the diaphragm In prior receivers having a pivotable dia ⁇ phragm, the diaphragm was spaced from the armature by approximately 0.060", and they were operatively coupled by a drive rod.
  • the drive rod could slightly flex, to conform to the action of the dia ⁇ phragm moving along a different arc than the moving armature.
  • the armature 28 is spaced from the diaphragm 40 by only about 0.002"-0.003", which does not provide suffi ⁇ cient room to assemble a drive rod. Further, such a shortened drive rod would have a diameter to length ratio too great to flex sufficiently.
  • the armature free end 28b is compliantly coupled to the dia ⁇ phragm 40, by a compliant compound, such as a compliant RTV having a durometer of 22 Shore A, or less.
  • a compliant compound such as a compliant RTV having a durometer of 22 Shore A, or less.
  • the diaphragm 40 pivots about the rigid edge 40b by the motion of the armature 28 at frequencies in accordance with an electrical signal applied to the motor 16. Because the diaphragm 40 pivots about the rigid edge 40b, the effective mass of the diaphragm 40, as seen by the armature 28, is re- quizd, thereby increasing the frequency of the motor resonance peak.
  • a locating embossment 54 is provided on each of the paddle 42 and the membrane 43 of the dia ⁇ phragm 40 to assist in the assembly of the receiver 10 by locating placement of the RTV bonding the diaphragm 40 to the armature 28.

  • a generally round tube 60 having a diameter of 0.018" is disposed in the first acoustic chamber 18.
  • the tube 60 is preferably 0.1" long, though its length and/or radius can be modified to adjust the frequency of both peak frequencies. Specifi ⁇ cally, increasing radius, or decreasing length of the tube 60 increases the frequency of each of the peak frequencies.
  • the structure of the above described receiver 10 lends itself to relatively simplified linear assembly, in that the receiver 10 comprises, in effect, three subassemblies.
  • the first subassembly comprises the armature
  • the first subassembly further includes a tab 64 for electri ⁇ cal terminations.
  • the second subassembly comprises the magnet housing 22, the magnets 26 and the coil 20.

  • the second subas ⁇ sembly is unique in that the magnet housing 22, which functions as a magnet return flux path, actually forms part of the receiver housing. While this design sacrifices flux leakage, the design permits significant reduction in the overall size of the receiver 10.
  • the third subassembly comprises the diaphragm
  • the third subassembly further comprises the tube 60 which is spot welded in the first housing portion 18.
  • the receiver 10 can be assembled in a linear manner by inserting the armature free end 28b of the first subassembly through the coil 20 of the second subassembly, and laser welding the second housing portion 17 to the magnet housing 22.
  • the armature free end then extends outwardly from the opposite end of the magnet housing 22.
  • a drop of the RTV in uncured, liquid form is placed on the locating embossment 54 of the paddle 42, and the first housing portion 18 is brought into engagement with magnet housing 22, and are laser welded together.

Abstract

Récepteur compact pour un appareil de correction auditive. Selon un mode de réalisation, le récepteur comprend une partie boîtier. Une membrane présentant une pluralité de bords périphériques est disposée dans la partie boîtier et définit des première et seconde cavités acoustiques. L'un des bords périphériques de la membrane est relié pivotant au boîtier. Les bords restants sont reliés de manière conformable au boîtier. Un moteur électromagnétique comprend un induit. Un joint de fixation conformable relie l'induit à la membrane de façon à déplacer cette dernière à certaines fréquences en fonction d'un signal électrique appliqué au moteur. Des premier et second orifices de sortie s'étendent à travers le boîtier. Le premier orifice de sortie est en communication acoustique avec la première cavité et le second orifice est en communication acoustique avec la seconde cavité. Les premier et second orifices de sortie coopèrent avec les permières et secondes cavités afin de supprimer les sons basse fréquence, ce qui permet d'obtenir un récepteur présentant une courbe de fréquence à bande passante généralement à haute fréquence. Selon un autre mode de réalisation, le premier orifice est supprimé ce qui permet d'obtenir un récepteur présentant généralement une courbe de fréquence à large bande. Selon une autre variante, deux des récepteurs à large bande sont réunis dos-à-dos, ce qui permet d'obtenir un récepteur doté d'une amplitude de sortie représentant le double de l'amplitude d'un seul récepteur, et dans lequel la vibration est réduite dans la mesure où la vibration des induits respectifs est déphasée de 180°. Un élément d'arrêt de cérumen est également décrit, ledit élément empêchant l'entrée de cérumen dans l'orifice phonique du récepteur.
