Hearing device

Abstract

To provide a hearing device having a construction that can easily exchange a charging battery.SOLUTION: In a hearing aid 1, a frame 10 is fixed to a face plate 3, a charging battery 30 to which a frame top 20 is adhered is housed in an inner side of the frame 10 after a circuit board 40 or the like is attached along their outer peripheral surface, and two lead wires bonded to the charging battery 30 are soldered to the circuit board 40. At the time of a battery exchange, the two lead wires are removed from the circuit board 40, and the charging battery 30 is fetched out from the frame 10 by lifting the frame top 20, and thereafter the new charging battery 30 to which the new frame top 20 is adhered is housed into the inner side of the frame 10, and each lead wire is soldered, and an operation is completed. Thus, the exchange of the charging battery of the hearing aid 1 can be easily performed without removing the circuit board 40 or the like. Also, since a claw part 11 is fitted into a notch 21, a disconnection of each lead wire caused by a rotation of the charging battery 30 can be previously prevented.SELECTED DRAWING: Figure 6

Description

[Technical field]

[0001] The present invention relates to hearing devices such as hearing aids, and more particularly to small hearing devices with built-in secondary batteries. [Background technology]

[0002] As hearing aids become smaller, smaller batteries are being used as their power source. Behind-the-ear and in-the-ear hearing aids usually use small button batteries (see, for example, Patent Document 1). Because it is difficult to replace small batteries and environmental considerations must be taken into account, more and more recent hearing aids are being equipped with built-in secondary batteries that can significantly reduce the number of times the battery needs to be replaced (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2006-514464 [Patent Document 2] JP 2012-191448 A Summary of the Invention [Problem to be solved by the invention]

[0004] Secondary batteries are consumables and generally need to be replaced every few years. The useful life of a hearing aid is five years, which is longer than the recommended replacement period for a typical secondary battery, so most hearing aids sold will have their batteries replaced. The secondary battery (rechargeable battery) built into the hearing aid is replaced by the manufacturer, who opens the hearing aid itself. In custom-made hearing aids that are made to fit each individual's ear, the circuit board and rechargeable battery are installed behind the part called the faceplate, which is visible from the outside when the aid is worn. In particular, with this type of structure, it is often necessary to remove the circuit board to replace the rechargeable battery, and because the hearing aid is small, this task is fraught with various difficulties.

[0005] Specifically, since the circuit board has soldered leads connected to each component such as the microphone, speaker, and antenna, these leads must also be removed when removing the circuit board from the faceplate. In addition, the button batteries used in typical hearing aids have positive and negative terminals close to each other, so care must be taken when replacing the rechargeable battery to avoid shorting these terminals. Since it is inefficient to perform such precise and careful work on a small device every time a battery is replaced, a solution is needed. These problems are not limited to hearing aids, but are common to all small hearing devices.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a hearing device having a structure that allows easy replacement of the rechargeable battery. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention employs the following listening device. Note that the following words in parentheses are merely examples, and the present invention is not limited thereto.

[0008] In other words, the listening device of the present invention is a listening device in which a housing includes a shell that forms the part that fits in the outer ear when worn and a faceplate that forms the part that is visible from the outside, and is equipped with a frame main body portion with an open top that is fixed to the surface of the faceplate facing the shell and has a wall that surrounds the outer circumferential surface of a rechargeable battery, and a circuit board that is arranged surrounding the wall, and the rechargeable battery can be inserted and removed from the open top of the frame main body portion.

[0009] With this type of listening device, a circuit board is arranged surrounding a frame that defines the storage space for the rechargeable battery, and the rechargeable battery can be inserted and removed from the open top of the frame, so there is no need to remove the circuit board when replacing the rechargeable battery, and the rechargeable battery can be easily replaced.

[0010] Preferably, in the listening device of the above-mentioned aspect, the listening device further comprises a frame lid portion that is attached to the rechargeable battery, the frame main body portion further having a plurality of first engagement portions extending upward from the wall, and the frame lid portion has a plurality of second engagement portions that correspond in shape and position to the plurality of first engagement portions, and when the rechargeable battery with the frame lid portion attached is housed inside the wall, the plurality of first engagement portions engage with the plurality of second engagement portions to fix the rechargeable battery to the frame main body portion.

[0011] According to the hearing device of this aspect, the frame lid is attached to the rechargeable battery and covers part of the terminal, so that the terminal can be removed or inserted with a tool without directly touching the battery, thereby preventing the occurrence of a short circuit. Also, the rechargeable battery stored inside the wall (the storage space for the rechargeable battery) is indirectly fixed to the frame by the engagement between the first engagement part and the second engagement part, so that the rechargeable battery can be prevented from moving within the storage space.

[0012] Preferably, in the listening device of any of the above aspects, the first engagement portion is a claw that extends upward from the wall with a tip portion bent in the direction of the central axis of the space inside the wall, and the second engagement portion is a notch formed corresponding to the shape and position of the claw, and when the rechargeable battery is stored inside the wall, the claw fits into the notch. Alternatively, in the listening device of the above aspect, the first engagement portion extends upward from the wall with a tip portion that is approximately U-shaped, and the second engagement portion extends downward from an outer end portion of the cover plate of the frame cover portion with a tip portion that is approximately U-shaped, and when the rechargeable battery is stored inside the wall, the rechargeable battery is rotated in the circumferential direction, so that the multiple second engagement portions engage with the multiple first engagement portions.

[0013] With this type of listening device, when the rechargeable battery is placed within the storage space, the multiple claws on the frame main body fit into the multiple notches on the frame lid portion, or the U-shaped portion on the frame lid portion engages with the U-shaped portion on the frame main body, so that the frame lid portion and, by extension, the rechargeable battery attached to it, have no room to move circumferentially, thereby preventing the rechargeable battery from rotating circumferentially within the storage space and preventing the lead wires connected to the rechargeable battery from being cut due to rotation.

[0014] More preferably, in the hearing device of any of the above aspects, the frame main body is prepared in advance in a plurality of different sizes, and any of the sizes can be fixed to the faceplate.

[0015] With this type of hearing device, the size (capacity) of the rechargeable battery used can be changed by replacing the frame main body with one of a different size, making it possible to increase the power of the rechargeable battery without having to purchase a new hearing device.

[0016] More preferably, in the hearing device of any of the above aspects, the frame lid portion forms a gap in a partial area between the frame lid portion and the attached rechargeable battery. Alternatively, in the hearing device of any of the above aspects, the frame lid portion has a ring-shaped portion at its upper portion.

[0017] With this type of listening device, when replacing the rechargeable battery, a thin tool can be inserted into the gap between the frame lid and the rechargeable battery, or into the upper part of the ring provided on the upper part of the frame lid, to apply upward force, making it possible to easily lift the frame lid and thus the rechargeable battery attached to it, and to easily remove the rechargeable battery from the storage space. Effect of the Invention

[0018] As described above, according to the hearing device of the present invention, the rechargeable battery can be easily replaced. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, the embodiment of the present invention will be described with reference to the drawings, taking an in-the-ear type custom-made hearing aid (hereinafter, simply referred to as a "hearing aid"). Note that the following embodiment is a preferred example of a hearing device, and the present invention is not limited to this example.

[0021] FIG. 1 is a diagram showing a hearing aid 1 according to one embodiment.

[0022] As shown in Fig. 1(A), the housing of the hearing aid 1 is broadly divided into a shell 2, which is the part that fits into the space from the ear canal to the concha when worn, and a face plate 3, which is the part that is visible from the outside. The shell 2 is individually made to fit the shape of the user's ear. The outer periphery of the face plate 3 is cut to fit the shape of the shell 2. A rechargeable battery is housed inside the hearing aid 1 along with various electronic components, and the shell 2 is removed when replacing the rechargeable battery.

[0023] 1(B) shows the state in which the shell 2 has been removed from the hearing aid 1. A circuit board is installed on the surface of the faceplate 3 that cannot be seen from the outside, i.e., the surface that faces the inside of the shell 2 in the completed state, and various parts such as a microphone, speaker, and antenna are connected to the circuit board, and a button-type rechargeable battery 30 is housed in a position surrounded by these circuit boards and parts.

[0024] FIG. 2 is a perspective view showing the face plate 3 and various parts assembled therein before the outer periphery is cut.

[0025] In the center of the faceplate 3, a frame 10 that defines a space for accommodating the rechargeable battery 30, a frame top 20 that has a shape corresponding to the frame 10, the rechargeable battery 30 accommodated inside the frame 10, a circuit board 40 installed along the outer peripheral surface of the frame 10, and various other parts not shown are fixed directly or indirectly to the faceplate 3.

[0026] In the following drawings, the state in which the above-mentioned parts 10 to 40 are fixed to face plate 3 is taken as the reference for the up-down direction, and the shape of each part will be described with the side facing upward on the paper of FIG. 2 as the top and the opposite side as the bottom.

[0027] 3 is a diagram showing the frame 10. Of these, (A) is a perspective view of the frame 10, (B) is a perspective view showing the frame 10 in an upside-down state, and (C) is a side view of the frame 10.

[0028] 3(A), frame 10, when viewed broadly, has a shape that resembles a substantially cylindrical shape with a portion cut out, forming a space capable of housing a rechargeable battery inside wall 14. Frame 10 also has two claws 11 that extend upward from wall 14 with their tips bent inward (more precisely, toward the central axis of the substantially cylindrical shape). The two claws 11 are provided at positions that are substantially symmetrical with respect to the central axis of the substantially cylindrical shape formed by wall 14, so as to sandwich the internal space formed inside frame 10 from both sides.

[0029] 3A and 3B, the frame 10 has three legs 12 protruding outward from the lower part of the wall 14, and each leg has a pin-shaped protrusion 13 on its underside. These protrusions 13 are used when attaching the frame 10 to the face plate 3.

[0030] 3(C) is a side view showing the frame 10 as viewed from a position where the two claws 11 are directly to the side, that is, the frame 10 as viewed in the direction of arrow C shown in FIG. 3(A). From this figure, it can be seen that the claws 11 extend higher than the wall 14, and that the tips of the claws 11 are bent inward with their inner surfaces 11a facing the internal space of the frame 10.

[0031] 4 is a diagram showing the frame top 20. Of these, (A) is a perspective view of the frame top 20, (B) is a perspective view showing the frame top 20 in an upside-down state, and (C) is a perspective view showing the frame top 20 adhered to the rechargeable battery 30.

[0032] As shown in Fig. 4(A), the frame top 20 has a shape in which a part of a lid having a slight depth has been cut out, and has two notches 21. The frame top 20 has a substantially circular shape in a plan view, and the two notches 21 are provided at positions that are substantially symmetrical about the center. The width of each notch 21 is designed to be large enough that the claw portion 11 of the frame 10 described above fits exactly into the notch 21. Also, as shown in Fig. 4(B), a step 23 is formed in the ceiling surface (lower surface) 22 of the frame top 20 so as to pass between the two notches 21, and the inside of the step 23 is recessed from the surrounding area.

[0033] Prior to assembling the components into the face plate 3, the frame top 20 is placed over the rechargeable battery 30 with the negative terminal 31 facing upward and the positive terminal 32 facing downward, as shown in Fig. 4(C), and its ceiling surface 22 is bonded to the negative terminal 31. At this time, due to the presence of the step 23 described above, a gap 24 is formed between the frame top 20 and the rechargeable battery 30. One end of the negative lead wire 33 is joined to the upper surface of the negative terminal 31, and is drawn outward from the gap 24. One end of the positive lead wire 34 is joined to the lower surface of the positive terminal 32.

[0034] In a button-type rechargeable battery 30, the negative terminal 31 and the positive terminal 32 are close to each other. However, in this embodiment, most of the area of ​​the negative terminal 31 is covered by the frame top 20, so that the rechargeable battery 30 can be held with tweezers without touching the negative terminal 31, thereby preventing the occurrence of a short circuit when inserting or removing the rechargeable battery 30.

[0035] 5 and 6 are sequential diagrams showing the flow of assembling parts into the face plate 3. The following will explain in chronological order.

[0036] In FIG. 5(A): A recess 5 for other components is formed in the center of the face plate 3, and receiving portions 6 having upwardly facing holes are provided at three locations on the outer periphery.

[0037] 5(B): The frame 10 is attached to the faceplate 3. Specifically, the frame 10 is positioned by aligning the protrusions provided on the undersides of the three legs 12 of the frame 10 with the holes in the receiving portion 6, and the protrusions are lightly press-fitted into the holes, thereby temporarily fixing the frame 10 to the faceplate 3. The legs 12 and the receiving portion 6 are then bonded together, thereby reliably fixing the frame 10 to the faceplate 3.

[0038] 5(C): A circuit board 40 and other electronic components are attached along the outer circumferential surface of the wall 14 so as to surround the frame 10. The circuit board 40 can be disposed below the frame 10 (for example, above the recess 5, etc.) in addition to being located along the outer circumferential surface of the wall 14. In this case, when the frame 10 is attached to the face plate 3, a part of the circuit board is attached so as to be sandwiched between the frame 10 and the recess 5. In either case, with the circuit board 40 and the like attached, the top of the frame 10 is completely open.

[0039] 6(D): The rechargeable battery 30 with the frame top 20 attached is housed inside (in the internal space) of the frame 10. Specifically, when the orientation of the rechargeable battery 30 is adjusted so that the positions of the two notches 21 match the positions of the two claws 11 and then the rechargeable battery 30 is fitted into the frame 10, the two claws 11 are deformed and bent outward accordingly, opening further apart than in their original state (the distance between the two claws 11 becomes larger than in their original state). Then, the rechargeable battery 30 is gradually pushed in while the tips of the claws 11 are aligned with the side surfaces of the rechargeable battery 30.

[0040] 6(E): When the rechargeable battery 30 is pushed completely in, the whole fits into the internal space of the frame 10, the deformation of the tabs 11 is released and returns to the original state, and the rechargeable battery 30 is housed in the internal space while being sandwiched between the two tabs 11. After this, the two lead wires joined to the rechargeable battery 30 are soldered to the circuit board 40, and the assembly of the components into the faceplate 3 is completed.

[0041] FIG. 7 is a diagram showing how the rechargeable battery 30 housed in the internal space of the frame 10 and its surrounding structure engage with each other.

[0042] 7(A): An enlarged plan view showing the housed rechargeable battery 30 and its surroundings. When the rechargeable battery 30 is housed, the two claws 11 fit snugly into the two notches 21, leaving no room for the frame top 20 to move in the circumferential direction. This fixes the frame top 20 and, by extension, the rechargeable battery 30 attached thereto to the frame 10, preventing the rechargeable battery 30 from rotating and preventing the lead wire from being cut due to rotation of the rechargeable battery 30.

[0043] 7(B): A vertical cross-sectional view (cross-sectional view taken along line BB in FIG. 7) showing the housed rechargeable battery 30 and its surrounding structure. From this view, it can be seen that the rechargeable battery 30 is housed in the internal space of the frame 10 so as to be sandwiched between two claws 11, that the inner surface 11a of the tip of the claw 11 faces the rounded corner of the negative terminal 31 of the rechargeable battery 30, and that the claw 11 covers the portion of the negative terminal 31 (rechargeable battery 30) on the outer periphery side of the rounded corner.

[0044] However, the extent to which the claw portions 11 cover the rechargeable battery 30 is shallow, and as described above, the claw portions 11 have a degree of elasticity that allows them to deform when the rechargeable battery 30 is fitted. Therefore, if an upward force is applied directly or indirectly to the rechargeable battery 30, the two claw portions 11 will bend outward and open, making it easy to remove the rechargeable battery 30 from the frame 10.

[0045] When replacing the rechargeable battery 30, the battery is moved back and forth between the state shown in Fig. 6(E) and the state shown in Fig. 6(D). Specifically, after removing the two lead wires connected to the rechargeable battery 30 from the circuit board 40, the frame top 20 is lifted to remove the rechargeable battery 30 from the frame 10 (Fig. 6(E) → Fig. 6(D)), a new rechargeable battery 30 with a new frame top 20 attached is fitted and housed in the internal space of the frame 10, and the two lead wires connected to the rechargeable battery 30 are simply soldered to the circuit board 40 (Fig. 6(D) → Fig. 6(E)), completing the replacement of the rechargeable battery 30.

[0046] As described above, in this embodiment, since it is not necessary to remove components such as the circuit board 40 from the face plate 3 when replacing the rechargeable battery 30, the rechargeable battery 30 can be easily replaced.

[0047] When it becomes necessary to replace the rechargeable battery 30, unnecessary portions of the face plate 3 have been cut off. In practice, therefore, the rechargeable battery 30 is replaced in accordance with the above-described procedure on the face plate 3 as shown in FIG. 1(B).

[0048] 8 is a diagram illustrating a structure used for removing the rechargeable battery 30. Of these, (A) shows a state in which the frame top 20 of the above-mentioned embodiment is adhered to the rechargeable battery 30, and (B) shows a state in which the frame top 50 of the modified example is adhered to the rechargeable battery 30.

[0049] As described above, when replacing the rechargeable battery 30, the frame top 20 is lifted and the rechargeable battery 30 is removed from the frame 10. However, as shown in FIG. 8(A), a gap 24 is formed between the frame top 20 and the rechargeable battery 30. Therefore, by inserting a thin tool such as tweezers into the gap 24 and applying upward force, the frame top 20 can be easily lifted, and the rechargeable battery 30, which is held down by the two claw portions 11, can be easily removed from the frame 10.

[0050] 8(B), a ring-shaped portion 55 may be provided on the upper portion of the frame top 50 in addition to or instead of the gap 24. In this case, too, the frame top 50 can be easily lifted by passing a tool through the ring-shaped portion 55 and applying an upward force, making it possible to easily remove the rechargeable battery 30.

[0051] Even if there is no gap or ring-shaped portion, the outer peripheral edge 26 of the frame top (the part indicated by the thick line in the figure) protrudes outward from the outer peripheral surface of the rechargeable battery 30, so that the frame top can be lifted and the rechargeable battery 30 can be removed by applying an upward force while placing the tip of a tool under the underside of this protrusion.

[0052] [Advantages of the present invention] As described above, according to the above-described embodiment and modified examples, the following effects can be obtained.

[0053] (1) The circuit board 40 and other electronic components are attached to surround the outer peripheral surface of the frame 10, and the top of the frame 10 is open, so that the rechargeable battery 30 to which the frame top 20 is attached can be fitted from above into the internal space of the frame 10. When replacing the battery, the rechargeable battery 30 to which the frame top 20 is attached can be lifted upward and removed from the frame 10, making it easy to replace the battery without removing components such as the circuit board 40 from the face plate 3.

[0054] (2) When the rechargeable battery 30 is accommodated in the internal space of the frame 10, the two claw portions 11 provided on the frame 10 fit snugly into the two notches 21 provided on the frame top 20, thereby preventing the rechargeable battery 30 from rotating circumferentially within the internal space of the frame 10 and, ultimately, preventing the lead wires connected to the rechargeable battery 30 from being cut due to rotation.

[0055] (3) Since most of the area of ​​the negative terminal 31 of the button-type rechargeable battery 30 is covered by the frame top 20, there is no need to directly touch the negative terminal 31 when inserting or removing the rechargeable battery 30 with tweezers, thereby preventing the occurrence of a short circuit.

[0056] (4) A gap 24 is formed between the frame top 20 and the rechargeable battery 30, and in addition to or instead of this, a ring-shaped portion 25 is provided on the upper part of the frame top 20. Therefore, by inserting a tool into the gap 24 or the ring-shaped portion 25 and applying upward force, the frame top 20 can be easily lifted, and the rechargeable battery 30 clamped between the two claw portions 11 can be easily removed from the frame 10.

[0057] (5) If multiple variations in frame 10 size are prepared in advance, the size (capacity) of the rechargeable battery 30 can be changed by replacing the frame 10 with one of a different size, making it possible to increase the power of the hearing aid without having to buy a new one.

[0058] The present invention is not limited to the above-described embodiment and modified examples, and can be implemented in various modified forms.

[0059] In the above-described embodiment, the frame 10 has a shape in which a part of a substantially cylindrical shape is cut out, but the shape of the frame is not limited to this, and may have, for example, a substantially complete cylindrical shape with walls connected in a ring shape. Also, the frame does not have to be cylindrical, and may be a cylindrical shape with a bottom. In other words, the frame should have at least an open top so that the rechargeable battery can be inserted and removed from above, and the tabs on the frame should fit exactly into the cutouts on the frame top.

[0060] In the above-described embodiment, the frame 10 has two claw portions 11 and the frame top 20 has two notches 21 correspondingly, but the number of claw portions the frame has and the number of notches the frame top has are not limited to this.

[0061] In the above-described embodiment, the frame top 20 is adhered to the negative terminal 31 of the rechargeable battery 30, but instead, it may be adhered to the positive terminal 32. The frame top 20 may be adhered in such a manner that it covers beyond the terminal it covers most of (in the embodiment, the negative terminal 31) and up to a part of the other terminal (in the embodiment, the positive terminal 32). The frame top 20 may be shaped to cover at least a part of one of the terminals of the rechargeable battery 30. Furthermore, the frame top 20 may be attached to the rechargeable battery 30 by a method other than adhesion.

[0062] In the embodiment described above, when the rechargeable battery 30 is accommodated, the two claws 11 of the frame 10 engage with the two notches 21 of the frame top 20, thereby fixing the rechargeable battery 30 to the frame 10, but the engagement between the frame 10 and the frame top 20 can also be achieved by another structure. Fig. 9 is a diagram showing a simplified view of a modified frame 110 and frame top 120 as an example of another structure.

[0063] As shown in the side view of FIG. 9A, the frame 110 has an engagement portion 116 that extends upward from the wall 114 and has a generally U-shaped tip. A protrusion 117 is provided at the inner end of the U-shaped engagement portion 116. The protrusion 117 has elasticity and can be deformed to some extent. Although not shown, the engagement portion 116 is provided at a plurality of positions that are generally symmetrical with respect to the central axis of the generally cylindrical shape of the wall 114 in the frame 110. In contrast, as shown in the side view and plan view of FIG. 9B, the frame top 120 has a plurality of engagement portions 126 (two in the illustrated example) that extend downward from the outer end of the cover plate 125 and have a generally U-shaped tip. A protrusion 127 is provided at the inner end of the U-shaped engagement portion 126. The protrusion 127 has elasticity and can be deformed to some extent.

[0064] When storing the rechargeable battery 30 to which the frame top 120 is attached, as shown in Fig. 9(C), the position of the engagement part 126 on the frame top side is slightly shifted from the position of the engagement part 116 on the frame side to adjust the orientation of the rechargeable battery 30, and then the rechargeable battery 30 is rotated in the circumferential direction while fitting the rechargeable battery 30 into the frame 110, whereby the engagement part 126 on the frame top side engages with and is fixed to the engagement part 116 on the frame side. Note that, since the engagement parts 116, 126 are provided with the protrusions 117, 127, respectively, the engagement will not be released by events such as vibrations that may occur during the use of the hearing aid. Therefore, with such a structure, the same effects as those of the above-mentioned embodiment can be obtained.

[0065] In the above-described embodiment, an in-the-ear hearing aid is described as an example of a hearing device, but a structure similar to that of the above-described embodiment with respect to housing the rechargeable battery can also be applied to other types of hearing aids (e.g., behind-the-ear) and hearing devices other than hearing aids (e.g., wireless earphones, etc.).

[0066] Furthermore, the configurations and numerical values ​​given in the course of explaining the hearing devices of the above-mentioned embodiments and modified examples are merely examples, and can be modified as appropriate when implementing the present invention. [Explanation of symbols]
