Description

466885 A7 B7 V. Description of the Invention (/) [Background of the Invention] Modern hearing aids include an earmold, which has the necessary electronic circuits for amplifying and adjusting other sound states to compensate the user's hearing loss. In a nutshell, these electronic circuits include: a microphone for receiving and receiving sound and converting the sound into an electrical signal; an electronic circuit for amplifying and processing the signal generated by the microphone; a speaker (also known as A receiver) for converting the processed signals into sound energy; and a battery for providing operating power to the hearing aid. The ear mold may be generally made of plastic, and is specifically designed and molded to fit into the ear of the person using the hearing aid. Generally, the ear mold can be made of hard plastic to have a long life and to make it washable periodically. Typically, the electronic circuitry of the signal processing circuit is adjusted to meet the specific hearing needs of its users. These requirements can be met by first testing the user's hearing and then providing a circuit with a frequency response characteristic that compensates for any hearing loss found during the test. After the required circuit is determined by these tests, it can be finally adjusted by a hearing aid expert to meet the final needs of the object. The above characteristics of the hearing aid structure, its manufacturing method and its adjustment method will make the hearing aid quite expensive. Conventionally, hearing aids have a battery, and because they are small and have only a limited operating life, they must be replaced periodically. Hearing aid users often complain about the difficulty of changing batteries. As hearing aids and battery systems become smaller, battery systems become more difficult to control. This is particularly difficult for the majority of hearing aid wearers who are over 65 years old and who have lost their ability to visually and motorly. For these users, if there are 4 paper sizes applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (please read the note on the back before filling this page) ------!-^ l Printed by the Consumers' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 466885 _____B7_______ V.

In addition, because it is disposable, it does not need to be used for major cleaning, repair and adjustment services. As mentioned above, hearing aids typically use metal-air batteries as the power source ' and especially zinc-air batteries. Metal-air batteries have the property that oxygen in the air is a catalyst for battery chemicals. For this reason, batteries are inactive in the absence of air. Zinc-air batteries actuate when air (especially oxygen) is allowed to enter the battery. For some zinc-air batteries, a pull-tab covers a small opening that allows air to reach one or more of the air-cathode assemblies. The drawstring system is designed to allow air to diffuse slowly into the battery. The battery is sealed with a pull strap, and the battery is free of oxygen, and does not maintain the same current as an unsealed battery. A strap that is impermeable to oxygen can be used to seal these air openings. Instead of, or in addition to, an oxygen-impermeable drawstring, the battery can be sealed in a nitrogen-filled pouch. For example, the relative humidity of nitrogen in the bag can be borrowed from 40 to 60% to prevent the battery from drying out. When the sealed bag system is opened or the drawstring system is removed, the oxygen system diffuses into the battery, the battery system returns to a zinc-air battery, and, for example, the voltage system can be increased from about 0.39 volts to more than 1.4 volts. Another embodiment of the present invention includes a non-recoverable 22 sealed in a hearing aid. The paper size is applicable to China National Standard (CNS) A4 (210 X 297 Gongtai) (Please read the precautions on the back before filling out this page) 1 pack i — — —— l_ ^ v Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 6 6 88 5 A7 B7 V. Description of the invention (/) Replaceable metal-air battery. However, the system needs a mechanism to allow air to flow to the battery. An example of a disposable hearing aid is shown in Figure 6A. The passage 64 is provided on the panel or cover 60 of the hearing aid 10, so that air can pass from the outside through the hearing aid housing to the cathode side of the battery 24. The passage is a sealed volume, so that when the outer hole is covered with a tape 59, no air is allowed to enter the passage 64 and reach the air inlet hole 68 to enter the cathode region 70 of the battery 24. During storage or shipment, disposable hearing aids can be exposed to an uncontrolled environment. The performance and life expectancy of metal-air batteries are sensitive to the environment. Battery life can be enhanced by minimizing exposure to S oxygen or carbon dioxide during storage. Even when the battery is not coupled to a load, these gases may cause chemical reactions in the battery and reduce its life. Therefore, it is important to protect and seal the integrated battery in disposable hearing aids. Separated from the environment. The traditional metal-air battery system uses non-air magnetic tape on the air inlet hole to protect the battery. To ensure that the air passage does not reach the cathode side of Kinkike during storage or shipment, according to the present invention, there are four different ways to seal the battery: (1) Seal the battery with non-permeable tape. Non-magnetic tape is applied to the air inlet hole on the cathode; (2) The battery is sealed with non-magnetic tape, and non-magnetic tape is applied to the air inlet hole on the panel; (3) Sealed with non-magnetic package A battery; and (4) the hearing aid housing is provided with an air-tight seal that can be closed again. 23 This paper size is applicable to 17 countries' standard (CNS) A4 (210 X 297 cm) (Please read the precautions on the back before filling out this page) ^ ^ I n ^ -eJI I, f > Intellectual Property of the Ministry of Economic Affairs A7 B7 885 printed by the Bureau ’s Consumer Cooperatives 1. Description of the Invention (/ 丨) The simplest and most direct way to seal the battery in a disposable hearing aid is to apply a non-magnetic as shown in Figure 6A The tape 61 to the battery 24 directly covers the air inlet opening 68. Using one of these sealing strategies, the disposable hearing aid is provided with a groove 58 in the shell 74 so that a vertical band T of the adhesive tape 61 connected to the battery 24 protrudes from the groove. When the user is ready to actuate the unit, the vertical strap T is pulled out of the unit along with the tape 61 attached to it, exposing the air inlet hole 68 of the battery, and actuating the battery. This embodiment also has the dual function of a pass-through switch, as described below.

Revealing content. The said patent describes a hearing aid with a removable drape which is used to seal the battery before use. In the exemplary embodiment of the present invention, the removable vertical strap 61 is positioned between the conductive contact 76 at the bottom of the signal processing circuit 20 and the corresponding contact 71 at the top of the battery 24 case to process the battery 24 by the signal. The circuit 20 is cut off until the vertical band 61 is pulled out. The removable vertical strap is substantially sealed to the vent 68 of the battery case. When the vertical string is pulled out, oxygen is supplied to the battery through the vent, and the battery is electrically connected to the hearing aid circuit. As shown in the aforementioned Leedom et al. Patent, one or both of the contacts 76 and 71 may be elastic contacts, which can be electrically connected after the vertical band 61 is removed. -An alternative way to place the tape on the battery is to cover the vent hole 64 with the tape 59 over the hearing aid.

Invention One of the design features of the disposable hearing aids is that an air path 68 'is provided to allow air to travel to the battery 24. To implement this theory, the battery 24 is well sealed in the hearing aid, so that no air system can enter the battery except through a specific passage. Typically, a 'hearing aid' has two channels, a proximal channel, through which sound pressure waves interact with the microphone; and a remote channel, the receiver generates sound pressure waves through this channel to actuate the eardrum. In one embodiment of the hearing aid according to the present invention ', the battery is sealed from air except for any of these pathways. The proximal path can be sealed to the battery or it can be integrally molded to the panel. The battery system that makes it in contact with the panel is sealed in addition to the proximal path. In addition, the distal path can use a non-conductive Sealed to the battery with a magnetic adhesive or seal. The proximal passage 64 is made of a hearing aid housing material, such as acrylic or Noryl, which 'connects the air holes in the panel to the air holes in the zinc-air battery case. Alternatively, the hearing aid shell itself may constitute a seal to surround these electronic circuits and batteries, as described below with reference to Figure 6B. With this design, no special access is required. Air can enter the unit in a controlled manner through specific air inlet holes. Instead of any of the alternative designs, a non-magnetic tape 59 may then be applied to the holes in the panel. The tape can be easily removed when the user is ready to actuate and use the product. What is not generally known is that a metal-air battery that blocks oxygen (〇2) but under electrical load will be empty of itself and will have less than the optimal energy capacity during use.

Description of the invention) Use non-magnetic tape and / or packaging, If the battery is connected to the hearing aid electronics, the battery will self-discharge. Therefore, it is desirable to provide a mechanism that can be incorporated into hearing aids to separate electrical loads from batteries during storage and shipment. Several types of devices can be used for this purpose. -A type of "on" switch is an electrical contact, so that once the hearing aid system is actuated, the system cannot be turned off. As shown in Figure 6A, the simplest embodiment of this type of mechanism is to place a non-conductive paper, tape, or film 61 between one electrical contact 76 of the signal processing circuit 20 and the battery 24 Corresponds between electrical terminals 71. The hearing aid is made of paper or film 61 for positioning and extends from the hearing aid shell M. To activate the unit, the user pulls out a tab T 'to allow the contact 76 to touch the battery terminal 71, thereby completing the electronic circuit. If it is not impossible, it is difficult to replace the membrane to shut down the unit. As mentioned earlier, this tape system can be used to block air from entering the battery so that when the tape is removed, the battery system is simultaneously activated and connected to the load. A more traditional open relationship can also be included. Non-disposable hearing aids typically have a motorized switch, or the battery itself is used as an on / off switch. Because disposable hearing aids do not have an -accessible battery, a motorized switch can be used. The advantage of an on / off switch is that the unit can be turned off during storage and shipment, and in use, it is turned on only when needed. The ability to turn the unit off allows the unit to be inserted and removed from the ear without feedback, as there is no sound amplification. Turning the unit off when not in use can also extend battery life. Another mechanism that can be used to extend battery life is an automatic switch.

Description of the Invention (Pair) Monitor the battery voltage and turn on the hearing aid when the voltage is higher than a predetermined threshold. As described above, in the absence of oxygen, the metal-air battery system operates like a zinc-hydroxide battery and has a lower voltage potential. During shipment and storage, metal-air batteries will have a draped non-magnetic tape on the terminals, and the voltage potential measured under a small electrical load should be less than 50% of the potential after full activation. An on-only open relationship for use with a strap sealed to a disposable hearing aid battery, described in the United States under a joint review entitled "Power Supply for Hearing Aid" proposed by Sjursen et al. Patent Application No. 09 / 124,948 is incorporated herein by reference for its disclosure of a power supply for disposable hearing aids. An exemplary circuit 700 according to the present invention is coupled between a hearing aid battery 24 and a hearing aid load 200, as shown in FIG. The circuit includes a transistor 710 whose emitter E is coupled to the anode A of the battery 24. The collector C of the transistor is coupled to one terminal of the load 200 (ie, the microphone electronic circuit of the hearing aid 10, the signal processing circuit 20, and the receiver 22), and the cathode of the battery 24 is coupled to the other terminal of the load 200 . A resistor 712 connects the cathode of the battery 24 to the base B of the transistor 710. When the voltage provided by the battery is lower than that required to energize the crystal 710, the load 200 is cut off by the battery 24, because the non-conducting transistor system represents an open circuit between the load and the battery. However, when the voltage provided by the battery exceeds the turn-on voltage for transistor 710, the transistor conducts current between its emitter E and collector C, allowing current to be applied to the load 200 〇27 (guess first W (Please read the notes on the back and fill in this page again.)

Description of the Invention (β) The circuit 700 or a similar circuit can be incorporated into a hearing aid according to the present invention. When the hearing aid is manufactured, the battery is in an unactuated state. This is achieved by one of the previously described sealing mechanisms. The circuit 700 continuously senses the potential of the battery 24 and prevents current from flowing to the signal processing circuit 20 of the hearing aid until the unit is removed from its package. The battery is actuated, so the voltage on the battery is increased to Its full potential. When this voltage is sensed, the circuit 700 allows a current to pass to the signal processing circuit 20. The benefit of this circuit is that it eliminates the need and cost of a motor switch. It also provides a longer storage life of the hearing aid 'and should be easier to use. Since the user does not need to open a mechanical switch or remove a mechanical barrier To connect the hearing aid electronics to the battery. An electronic open relationship such as the one disclosed above can also be used with an air-blocking switch to reduce the transfer of oxygen and moisture from the battery to the battery and from the battery when the hearing aid system is not in use. Figures 6B and 6C show an embodiment of the disposable ear type (ITE) hearing aid 10 with an air-blocking on / off switch. Figure 6B shows a disposable structure with a modular structure The hearing aid includes a panel 60, which protects the sensitive microphone 18 'tethered-a pull rope 62, and is provided with an opening 64 through which air can pass to the battery 24. The hearing aid also includes a signal processing circuit 20 It is connected to the microphone 18 and is connected to the battery 24 and a flex circuit 78 via an electrical circuit contact 76. The flex circuit 78 provides a connection between the signal processing circuit 20 and the receiver .22.

Description of the invention (4) Coupling to the flex circuit 78 via the elastic contact interface 80. The elastic contact interface 80 is equipped with the contact 82 and the flex circuit 78 between the receiver 22 between. The battery 24 and the signal processing circuit 20 are permanently mounted on a plastic case 74. The battery includes a metal wall (which is also the anode of the battery), a decomposable mixture 73, and a cathode grid 70. The battery is enclosed by a top cover 75. The top cover 75 is separated from the anode 72 by an insulator 77. An opening 68 in the top cover provides air from the air channel 66 to the cathode grid 70. In one embodiment, as shown in FIG. 6C, the panel 60 is configured to slide relative to the microphone 18 and the hearing aid electronic circuit π In and out. When the user pushes the hearing aid into his ear, the panel is pushed in to open the air passage 66. When the user pulls the pull cord 62 to remove the hearing aid from his ear, the panel 60 is pulled out to close the air passage 66. When the panel ^ 0 is pushed in, the air passage 66 is opened to allow air to enter the battery 24 through the opening 64, the air passage 66, and the battery air hole 68 in the panel. When the panel 60 is pulled out, the air passage 66 is blocked, as shown in FIG. 6C. According to other aspects of the invention, it is desirable to hide the hearing aid 10, as it is highly likely that there is a stain associated with wearing the hearing aid. This taint may be perceived as hearing impaired and elderly. Therefore, in one embodiment, the panel 60 in FIG. 6D may be composed of a substantially translucent or transparent material. For example, the material can be "colored" to a color such as flesh or basic. When the hearing aid 10 is inserted into the ear canal for use, only the panel 60 is essentially visible. The translucent or transparent panel 60 can choose the natural color of the user's ear to help 29 paper sizes apply the Chinese National Standard (CNS) A4 specification (21 × 297 mm) (Please read the precautions on the back before filling in this Page).

Description of the invention (> " |) _ to hide the hearing aid 10 in the user's ear. In another embodiment, the panel 60 can be formed with a reflective surface, which can also help to hide the vision aid 10. In yet another embodiment, the panel 60 may be formed with a compound curve as shown in Fig. Q to better reflect the contour of the user's ear. Figures 6D-0H illustrate another embodiment of a switch mechanism for opening and closing the hearing aid 10 according to the present invention. Advantageously, the hearing aid 10 is turned off when not in use to extend battery life. In this embodiment, the pull rope 62 extends through the panel 60 and is connected to the insulating member U8, which is also referred to as a sliding member, as shown in FIG. 6E. In one embodiment, the absolutely green member 128 is formed of plastic or other suitable materials through an injection molding process. The insulating member 128 includes an aperture 130 therethrough, and also includes a tapered leading edge 134 to facilitate its insertion into the hearing aid 10 during the manufacturing process. Preferably, the draw cord 62 is strong and slender so as not to be forced into the user's ear, and is relatively rigid. In one embodiment, the pull rope 62 is made of a single core nylon material. The pull rope 62 is thermally or otherwise joined to the insulating member 128. Figure 6F illustrates the "on" position of the hearing aid. In this position, the insulating member 128 allows a switch contact member 132 to contact the cathode C of the battery 24B through the aperture 130. Note that the anode A and the switch contact member 132 are always electrically connected to the circuit board. In this "on" position, the insulating member U8 is inserted into the hearing aid and faces the tip 94 and is held by a stop member 136. When the user pulls the pull rope 62, the insulating member 128 is moved so that the switch contact member 132 is separated from the cathode C, as shown in Figure 6G. 30 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling out this page) Loading -------- Order --------- ^-v ...

In this case, the stopper member 136 prevents the insulating member 128 from leaving the hearing aid 10. As shown in Figure 6H, the insulating member 128 preferably includes an inwardly protruding member or catch 138 that allows the stop member 136 to pass therethrough. The detent 138 temporarily “locks” the insulating member 1M in the respective “on” and “off” positions. In a preferred embodiment, the hearing aid 10 is inserted or removed by a user holding the pull cord 62. More preferably, the action of 'removing the hearing aid 10' will "close" the hearing aid, with the detent 138 allowing the insulating member 128 to the position shown in Figure 6G. When the hearing aid is inserted into the ear, sufficient force is imparted to the insulating member 128 to "open" the hearing aid. Therefore, the action of inserting and removing the hearing aid from the ear canal is to “open” and “close” the hearing aid, respectively. Although disposable hearing aids have been described above with a metal-air battery, hearing aids can use other types of batteries. The main advantage of these other batteries is their higher operating voltage. As the operating voltage of the battery drops below 2 volts, the design and manufacture of audio integrated circuits becomes extremely difficult. The main disadvantage of non-metal-air batteries is their reduced energy capacity. Typically, metal-air batteries have twice the capacity of non-metal-air batteries. When disposable hearing aids use non-metal-air batteries, the problems of sealing and providing air passages are eliminated.

Description of the invention (4). However, the expected life will be about half the life of metal-air batteries. Disposable hearing aids can also use rechargeable batteries, as shown in Figures 8A and 8B. Rechargeable batteries can be sealed inside the unit. However, an additional mechanism is added to the unit, allowing external energy to be transferred to the battery for recharging. This can be achieved by providing an external battery contact 85 as shown in FIG. 8A to allow direct conduction, or by providing an energy transfer device such as an inductive line 810 shown in FIG. 8B or A photocell (not shown) to allow the battery to be charged by inductive alternating current (AC) or a light source. In all cases, the battery will be charged when it is not in use, such as the night before. In one possible configuration, the hearing aid system may be provided with a charging unit (not shown) that provides a regulated DC charging potential to the direct electrical contact 85 'or it provides a regulated AC potential to an inductive coil in the charging unit (not shown). display). If the hearing aid includes an external battery contact 85 ', the battery is fully charged under the control of the charging unit. However, if the hearing aid is inductively coupled, as shown in Figures 8B and 8C, in addition to the inductance line 810, the hearing aid may include a rectifier 812 to convert the induced AC potential to DC potential, which is applied to charge the battery. twenty four. One advantage of using rechargeable batteries is that the overall life of the unit can be extended, making it more economical. In addition, the piezoelectric potential of the rechargeable battery can be higher than the voltage potential of the metal-air battery, allowing more flexibility in electronic circuit design and improved sound quality. For example, 'compared to 1.3 volts for zinc-air batteries, rechargeable lithium metal batteries have an operating voltage of 3 volts. 32 (Please read the precautions on the back before filling out this page) Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs This paper is printed in accordance with China National Standard (CNS) A4 (210 X 297 mm) A7 4 6 6 8 8 5 V. Description of the invention (? °) Figure 9 illustrates another embodiment of the hearing aid 10, which may be disposable or non-disposable. As shown in the figure, the battery 24 separates the microphone 1s from the receiver 22 'so as to minimize the feedback of sound therebetween. To obtain the maximum life from the battery 24, the case for the battery is closely fitted to the inner shape of the ear groove. In one embodiment, a 'battery contains a plastic material that is found to be a comfortable material when inserted into the ear canal. In another embodiment, the case or wall portion 72 of the battery comprises a metallic material. The seal 90 is injected between the battery wall portion 72 and the plastic shell layer 74 to minimize feedback between the microphone 18 and the receiver 22, and to keep the battery 24 from rattling against the shell layer. As shown in the figure, the battery 24 includes at least one step portion 92 so that the overall shape of the battery substantially matches the ear groove portion between the ear hole and the first curved portion. This is to increase battery life by increasing the total zinc volume. The electrical connection from the anode and the receiver to the microphone part of the circuit can be a single-sided flex circuit of an adhesive guard applied to the individual circuit side of the battery, a metal rod, a trace printed on the wall of the insulated battery, or other suitable mechanism. A resilient contact interface panel 80 completes the circuit between the receiver 22, the anode, and the flex circuit 26 on the battery. Zinc-air batteries are generally configured for hearing aid applications. The reasons include: (1) it has the highest capacity-to-volume ratio of any miniaturized battery; (2) its discharge curve is fairly flat; (3) ) Compared with mercury oxide and silver oxide batteries, zinc-air batteries show a relatively stable voltage with large currents; and (4) the nature of these batteries determines that the internal resistance is favorable for circuit design.

Description of the invention (3 丨) Proper operation. Figure 10 illustrates a preferred embodiment of the hearing aid 10, including the overall shape of the mushroom-like tip 94 and the two half-shells 74, which are joined together. The two shell layers 74 constitute a base portion 86 enclosed in an oval section, which extends into an elongated curved middle section 87. Preferably, the size of the oval is changed as it proceeds toward the middle section 87. In one embodiment, the two half shells 74 are sometimes referred to as "dam shells". When the hearing aid 10 is assembled, the components are inserted into one or both of the clam shells, and the shell layers are sequentially bonded, joined, and fastened (or a combination thereof) together. 11 The figure is a cut-away side view of a shell 74 that houses the receiver 22, the battery 24A, and the microphone 18. The two shell layers 74 are joined together to complete the shell. The battery 24A shown in Fig. 11 is a standard zinc-air battery, which has a substantially cylindrical geometry. Typically, the structure of these zinc-air batteries is composed of a cathode container, an anode container, an insulator, and an electrolyte. It is noted that the cathode container and the anode container covered with nickel to prevent corrosion and ensure good electrical contact are separated by nylon insulators. The cathode, which is electrically connected to the cathode container, consists of a catalyzed carbon rod that acts to reduce oxygen from the air. Alternatively, these anodes are a colloidal mixture of zinc powder and electrolyte, which is typically a highly conductive solution of potassium hydroxide (KOH) in water. The battery 24A shown in Figure 11 is a conventional 312 zinc-air type. The battery is the largest conventional battery that can be installed in a battery room composed of two half-shells 74. 34 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ------------ install --- {Please read the precautions on the back before filling this page) 1 ts K n 丨 --------- ^ .. 4 S 6 8 8 5 Α7 '~~~ ------------- 5. Description of the invention (Θ) The customized battery 24B of the invention is illustrated in two perspective views of FIGS. 12 and 13. In particular, Fig. 12 shows the bottom B of the anode A, and Fig. 13 shows the top T of the cathode C. It should be noted that the anode is longer and thinner than conventional fresh-air batteries. The tapered portion is actually a slightly ventilated portion, which conforms to the process generally used for zinc-air batteries. In addition, the radial dimension of the battery has been increased to better fill the available cavities in the shell 74. To facilitate the change in radial dimension, the height of the cathode container has been minimized 'to reduce the adverse double packaging effects attributable to the structure of the anode container, insulator, and cathode container. As can be inferred from Fig. 14, if a full height cathode container is used, the radial size of the anode container must be smaller than the suggested one. As a result, the capacity of the custom battery will necessarily be reduced. Therefore, the height of the 'cathode container is as small as possible while still maintaining a proper seal. The net effect of these changes can be observed by comparing Figure 14 with Figure 1.1. It can be seen that the custom battery 24B occupies a much larger part of the space available for power supply. In fact, by calculating the volume of the custom battery 24B and comparing it with a standard 312-type battery 24A, a quantitative measurement of the increased capacity can be obtained. In this case, the volume of 0.01757 in3 (cubic inches) for a custom battery is calculated, compared to 0.008719 in3 (cubic inches) of a standard 312 battery. Since the volume of the battery has increased by more than 100%, the life of a hearing aid will approximately double. Figure 15 illustrates that the custom battery 24B is inserted into the shell 74, and the microphone 1S and the receiver 22 are positioned in position β.

Preferably, the rods 100 are pressed on The zinc and cathode plates 96 are sealed in a plastic case 74. In one embodiment of the present invention, it is preferred to automate the assembly of the hearing aid as much as possible to reduce manufacturing costs. One aspect of the present invention is to provide a quick connection mechanism, for example, to connect the receiver and the battery to each other at the same time without welding or joining these small parts or contacts. The phrase "simultaneously" is understood to mean that it occurs at the same time. Therefore, the necessary electrical contacts are completed at the same time by the quick connect mechanism. Figures 20 and 21 illustrate an embodiment of a quick connect or coupling mechanism that includes a saddle member 114, which is preferably formed from a non-conductive material such as plastic. The saddle member 114 supports at least one contact member 116, which The anode A of the battery 24B and the circuit board 118 in the microphone portion are interconnected.

In one embodiment, All internal components including the battery 24B, the receiver 22, the microphone 18, and the tip 94 are placed in a first or bottom half shell 74. Including the contact member 1 The saddle components of 16, 122 are placed on the top to complete all necessary interconnections between the components. The second or top half shell layer 74 is preferably buckled and joined to the bottom half shell layer to form a hearing aid 37 This standard applies to China National Standard (CNS) A4 specifications (210 X 297 Gongchu) ^ Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 6 6 885 A7 B7 V. Description of the invention (u) 10. In an alternative assembly sequence The saddle member 114 is positioned on the top half shell 74 before the top shell is installed before the completed bottom shell assembly. The comb-like feature (not shown) is preferably attached to the top half shell 74 To guide the elastic ends and assist the receiver 22 to prevent bending damage when the elastic contacts exert their force. Preferably, the 'twisted end 120 has oxidation resistant grease or gold plating on it to ensure long Reliability during contact. In brief, if the hearing aid is used frequently, the battery life is usually determined by how often the hearing aid 10 is used. In the case of infrequent use, the battery life will be limited, assuming that the battery is exposed In low humidity, it becomes dry and becomes ineffective, or if it absorbs too much moisture due to exposure to high humidity, it becomes swollen and ineffective. Therefore, according to one aspect of the present invention, the useful life of hearing aid 10 is provided by Extend more than one battery that can be actuated, preferably one battery at a time. Multiple battery systems can be used in any hearing aid device, including disposable and non-disposable ears, ditch (ITC, in -the-canal), corneally-in-the-canal (CIC), and behind-the-ear (BTE) hearing aids. Figures 22 and 23 illustrate one of the 10 hearing aids. In one embodiment of the switching device, the hearing aid 10 has a plurality of batteries that can be actuated sequentially. The switching device 140 is positioned adjacent to a first battery 142 and a second battery 144. In Fig. 22, the switch 140 is in the "off" position, and an insulating member M1 of the switch covers a portion of each battery M2 '144. At this position, each battery 142, 144 is electrically connected to the ground, and the electricity is 38.

Description of the invention (U) The pools 142 and 144 are not electrically connected to the circuit board of the hearing aid 10 ° Each battery 142, 144 includes a hole H6, which becomes actuated when exposed to air. In the position of FIG. 22, the switches 140 are all covered on the two holes 146. When the switch 140 is moved to one of the two batteries, such as a battery 142 (see FIG. 23), the battery hole 146 is exposed to the air through a gap 148 of the insulating member H1. At the same time or about the same time, the battery 142 is electrically connected to the circuit board to power the hearing aid 10. In one embodiment, the switch 140 includes a conductive member 150 that completes the circuit to the circuit board to power the hearing aid 10. Therefore, the switch 140 can be used to "on" and "off" the hearing aid 10 and to select one of the batteries of the hearing aid. Figure 24 shows another embodiment of a device for selecting and activating a battery. In this embodiment, a first insulator 152 and a second insulator 154 are located adjacent to the respective batteries 142, 144. As in the previous embodiment, each battery 142, 144 is grounded. In the "off" position, the insulators 152, 154 separate the conductors 156, 158 from the batteries 142, 144 to cut off the circuit 162 to the hearing aid load 2000. The insulator 152 includes a conductive strip 160 thereon, which completes the circuit between the battery 142 and the load 200. When the insulator 154 is moved to allow the conductor 158 to contact the battery 144. When the battery 144 has expired, the insulator 152 is moved to allow the conductor 156 to contact the battery 142. Preferably, only a single battery is connected to the circuit 162 at a given time. Otherwise, if the first battery system is not cut off after use, its lower voltage will become the leakage situation of the second battery and shorten its life.

Description of Invention (π) When the 152 is moved, the battery 144 is cut by the circuit 162. Fig. 25 illustrates an embodiment of a switching mechanism 164 for selecting a battery to power a hearing aid 10 and for turning the hearing aid "on" and "off". In this embodiment, a rotary switch member 166 is preferably formed of an insulating material such as plastic and covers individual holes 146 of the batteries 142, 144, and 144. It is understood that more than three batteries can be used according to the present invention. The switching member 166 also includes an electrical contact 168 that completes the circuit that powers the hearing aid 10 when positioned on a battery such as the battery 142. The switching member 166 'includes an aperture 170 that provides air to a selected battery to actuate the battery. In one embodiment, the switching member 166 is rotated by an actuating member 172 to select and actuate a battery. In one embodiment, the actuating member 172 is rotatably supported by the housing or shell 74 of the hearing aid 10, and the switch member 166 is rotated when the member Π2 is rotated by the user. Preferably, the switch member 166 includes a detent thereon to allow the switch member to be "clicked" into position. In the embodiment of Fig. 25, four detents are used, one for each of the batteries 142, 143, and 144, and the other for the "off" position. In another embodiment, the actuating member 172 can rotate one of its members (not shown) that supports the batteries, while the switch member 166 remains in position. Typical hearing aids are designed to have a product life of about 4 to 5 years. For this reason, the materials selected for these appliances must be robust enough to withstand a given unit's lifetime over its life cycle of 40 (please read the precautions on the back before completing this page)

The printed paper is printed in accordance with the Chinese national standard (CNS > A4 (210 X 297 mm) A7 lS6 885 ___B7__ 5. The invention (β) experienced normal wear and tear. Due to the normal wear and tear of hearing aids. Performance and appearance should not deteriorate significantly during this period of 4 to 5 years, and in general, it is intended that the materials used are quite hard 'promoting the discomfort experienced by wearing the device. About For the problem of discomfort, the tip 94 is preferably composed of a soft and compliant material, and the shell 74 is composed of a rigid plastic material. It has been found that this kind of tip structure can greatly improve The perceived comfort of the unit. However, since the service life of this highly compliant material is expected to be greatly reduced when compared to its relatively rigid counterpart (ie, shell 74), it may have to be planned The life of the product is limited so that the user is not put at risk of deterioration due to wear of the hearing device. In addition, since the hearing aid 10 is preferably combined with a zinc-air battery Limiting the life of this product also minimizes the problems associated with battery swelling due to extreme discharge. Therefore, three methods for automatically turning off hearing aids are described later. The first method is to monitor hearing aids 10 Turn on time to determine an appropriate turn off time. Monitoring can be implemented in software, hardware, or a combination of both. Referring to Figure 26, in one embodiment, when the hearing aid 10 is turned on by the switch 106 At this time, an electronic timer 108 is started to help keep track of the elapsed time. The output of the timer 108 is incremented to the counter 110 of the microcomputer 112 in the hearing aid, and the microcomputer 112 stores the elapsed time data. Therefore, when the switch 106 is in the "off" position, this data will not be lost, and the power is provided to the counter. As a result, to avoid excessive battery consumption, the power demand of these counters is preferably at most 41. This paper size applies the Chinese National Standard (CNS) A4 specification (21〇χTear mm.) {Please read the precautions on the back before filling in this page) 、、, Install! ----- Order --- ----- ^ Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy β Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy 88 5. A7 _B7____ V. Description of the invention) Small. As another solution to continuously supply power to these counters, a non-volatile (NV, nonvolatile) memory system can be used to store the on (on) time data. Although NV memory will obviate the need to provide power to the circuit when the hearing aid system is turned off, the trade-off is the power consumption associated with storing information in the memory. When the user moves the switch to the "off" position, the timer 108 is stopped. This avoids any increment to the counter 110 when the hearing aid is switched off. The on / off cycle described here is repeated until it exceeds a predetermined time limit. Once the predetermined time limit is exceeded, the hearing aid 10 is switched off. This can be achieved, for example, by disabling the output of the driver 22 to be driven. However, before the unit is turned off, a periodic audible warning of an urgent shutdown may be generated to warn the user of the urgency of the shutdown. The second method is to track the elapsed time from the moment the user moves the switch 106 to the "on" position. Similarly, when the hearing aid 10 is turned on by the user, the 'timer 108 starts. However, in this embodiment, a flag is set on the microcomputer 112, which indicates that the unit has been turned on at least once. The current state of this flag prevents the timer 108 from being turned off when the unit is turned off. So 'whether the unit is on or off, the output of this timer is to continuously increment these counters. After the switch is initially actuated to the off position, power is provided to the timer and counter. This process continues until a predetermined time limit is exceeded. With regard to disposable hearing aids, this time limit may correspond to a predetermined number of days, such as 7, 14, or even 30 days. If the unit is rechargeable, at that time 42 (Please read the precautions on the back before filling this page) Binding --------- The size of the produced paper is applicable to China National Standard (CNS) A4 specification (210 X 297 mm) 6 6 885 A7 ____B7____ 5. The description of the invention (shame) may be an extended time period, such as 90 days or more. These time interval patterns are preferably relatively easy for a user to remember. Preferably, when the time limit is exceeded, the unit will shut down after a periodic audible warning has been generated. Another closing method according to the invention is based on a calendar. According to this embodiment, the hearing aid 10 is operated only in a selected month (for example, only January). Since the hearing aid 10 acts only on the selected month, the user benefits from having a replacement unit at or near the beginning of each month. Preferably, this technique is independent of the position of the switch 106 and is implemented in the following manner. First, the hearing aid electronics include a mechanism to track the date and time. This can be achieved by supplying date and time information to the circuit during the planning of the hearing aid 10. Since the hearing aid 10 keeps track of the date forward from this point in time, power is supplied to this clock function. The month in which the hearing aid 10 will operate can be determined when the user first turns on the unit for a predetermined period. This period of attention should be long enough to avoid inadvertent month selection. In a preferred embodiment, there is a limit on the number of times the user can activate the switch 106 before the hearing aid is finally selected for the month of operation. If desired, the hearing aid 10 can be designed so that it provides a grace period. For example, it can be applied to a period that includes two days before and two days after the selected month.
