First Example (Electric Megaphone)
The battery mounting device and battery case of the present invention are suitably used for, for example, an electric megaphone. However, not only the electric megaphone, if Mote you to use the battery, it can be used for a variety of electronic equipment or electrical equipment such as a tool.
Electrical megaphone 1 shown as an example of electronic equipment or electrical equipment, as shown in FIG. 1, for example horn mouse 2, megaphone body 3 and a handle 4. The battery mounting device 100 of the present invention is provided in the rear portion of the megaphone body 3. As shown in FIG. 2, the electric megaphone 1 includes a magnetic circuit including a ring-shaped permanent magnet 5, a yoke 6, and a plate 7 inside the horn mouse 2, and a magnetic gap formed between the yoke 6 and the plate 7. A voice coil (not shown) is inserted into the. The upper end of the voice coil is coupled to the dome-shaped vibrating plate 8, and the acoustic signal input to the voice coil acts together with the porcelain circuit to be converted into acoustic vibration by the vibrating plate 8. An equalizer 9 and a throat 10 are provided in front of the diaphragm 8, a tube 11 and a reflector 12 are attached to the opening portion of the throat 10, and acoustic vibration is emitted from the opening portion of the horn mouse 2.

The reflector 12 is screwed to the horn mouse 2 with a screw 13, and the screw 13 is further tightened to the boss 14 of the megaphone body 3 to connect the horn mouse 2 and the megaphone body 3. When connecting the horn mouse 2 and the megaphone body 3, as shown in FIG. 4, the throat packing 15 is fitted inside the horn mouse 2, and the horn mouse 2 is attached to the outside via a waterproof packing 16 made of rubber, flexible resin, or the like. Fill the gap between 2 and the megaphone body 3 to make it an airtight and waterproof structure.

Further, as shown in FIG. 4, the microphone unit 21 is arranged at the inner rear portion of the megaphone body 3. The microphone unit 21 is composed of a main microphone 22 and a sub microphone 23, and the main microphone 22 and the sub microphone 23 are attached to the rear of the megaphone body 3 via thin films 24 and 25 having a cushioning effect and a waterproof effect, for example, rubber. That is, they are put into thin films 24 and 25 such as rubber formed so as to wrap the main microphone 22 and the sub microphone 23, and are stored in the microphone restraint 26. In this way, the main microphone 22 and the sub microphone 23 housed in the microphone restraint 26 are fitted into the ribs 27 formed on the rear inner wall of the megaphone body 2, and the main microphone 22 and the sub microphone 23 are arranged side by side in the horizontal direction of the electric megaphone. The main microphone 22 is arranged on a vertical line passing through the center line of the electric megaphone, and a small opening 28 (see FIGS. 3, 6, and 9) is formed in the megaphone body 3 where the main microphone 22 faces, and is external. The sound is input to the main microphone 22.

The main microphone 22 is covered with a thin film 24 such as rubber to obtain a waterproof effect, and an opening 29 is formed in the thin film 24 such as rubber corresponding to the opening 28. By arranging the openings 28 and 29 so as to face each other in this way, acoustic vibration is input to the main microphone 22. Further, since the thin film 24 made of rubber or the like has a buffering action, it prevents the vibration of the megaphone body from being input so that an input signal having a high S / N ratio can be obtained.
On the other hand, the sub microphone 23 is used for preventing howling. Therefore, the megaphone body 3 at the position where the sub microphone 23 faces is not formed with an opening, and the external sound is not input. As described above, since the megaphone body 3 in front of the sub microphone 23 has no opening, waterproofing can be completely performed. However, as shown in FIGS. 6 and 9, a small hole may be formed in the megaphone body 3 at a position corresponding to the sub microphone 23 so that the external sound can be input to the sub microphone 23 as well.

In the electric megaphone 1, the acoustic vibration output from the horn mouse 2 wraps around the electric megaphone 1 and is input to the main microphone 22, and the back pressure of the diaphragm 8 passes through the inside of the electric megaphone 1 to the main microphone. Howling is caused by the acoustic vibration input to the 22 and the sub microphone 23 and the acoustic vibration input to the main microphone 22 and the sub microphone 23 by the vibration of the electric megaphone itself. Among them, the sub microphone 23 receives the vibration due to the back pressure of the diaphragm 8 and the vibration due to the vibration of the megaphone itself in the same phase. Howling is prevented by converting the vibration input to the sub microphone 23 into an electric signal in this way and inputting it to the amplifier in the opposite phase to the electric signal converted by the main microphone 22 for mixing.

A printed circuit board 31 on which a circuit 30 composed of electric components constituting an amplifier is mounted is attached to the upper rear portion of the megaphone body 3. The printed circuit board 31 is attached so as to be sandwiched between a rib (not shown) formed on the rear wall of the megaphone body 3 and a substrate holder 32. The substrate retainer 32 is made of a resin material, for example, ASA resin, and includes a battery connection terminal 33 on the minus side and a battery connection terminal 34 on the plus side, which are electrically connected to the circuit 30. The printed circuit board 31 is attached by screwing the board retainer 32 to the rear wall 104 of the battery case storage portion 102 of the battery case storage portion 102. As shown in FIGS. 6 and 9, a small opening is formed in the rear wall 104 of the battery case storage portion, and the tips of the battery connection terminal 33 on the minus side and the battery connection terminal 34 on the plus side protrude from the opening.

And it is formed to be slightly larger than the battery case 101 so that it can be taken out (see FIGS. 4, 6, and 9). In the case of this embodiment, since the battery case 101 has a substantially rectangular parallelepiped outer shape, the battery case storage portion 102 is also formed into a substantially rectangular parallelepiped shape. The battery case storage portion 102 includes four side walls 103 of the battery case storage portion surrounding the periphery and a rear wall 104 of the battery case storage portion forming a bottom plate. The four battery case storage side walls 103 and the battery case storage rear wall 104 are continuously integrally molded with the megaphone body 3 using a resin material.

Inside the side wall 103 of the battery case storage portion 103, one fitting structure 105 of the battery case 101 is formed near the opening 107 of the battery case storage portion 102, and the battery case is formed on the opposite inner side surface of the side wall 103 of the battery case storage portion.

It may be arranged at an asymmetric position with respect to a line orthogonal to the central axis of the case accommodating portion 102 (or the insertion direction of the battery case 101). That is, they are arranged at almost right angles or at arbitrary angles.

(Battery case)
5 (a) is a perspective view of the battery case 101 disassembled, FIG. 5 (b) is a cross-sectional view of the battery case with the battery case 101 assembled, and FIG. 5 (c) is a part of the battery case 101. It is a perspective view which is seen through. The battery case 101 includes a battery mounting portion 110, a lid 111, and a sliding structure portion 122. In this embodiment, the battery mounting portion 110 arranges four AA batteries (not shown) in parallel. The type and number of batteries are arbitrary. The size and shape of the battery mounting portion 110 vary depending on the type and number of batteries. Further, the size and shape of the battery mounting portion 110 change depending on the series connection, parallel connection, or series-parallel connection of the batteries. This embodiment shows an example in which four AA batteries are arranged in parallel and connected in series, and the outer shape of the battery mounting portion 110 is formed into a substantially rectangular parallelepiped shape. The battery mounting portion 110 includes both ends of the battery, that is, the battery end holding portions 113a and 113b that hold the positive and negative electrodes, the partition 114 that forms the partition between the batteries, and the four battery side portions that hold the battery side. It is composed of holding portions 115a to 115d, and the battery end holding portions 113a and 113b, the partition wall portion 114, and the battery side holding portions 115a to 115d are integrally molded with a resin material. The four battery side holding portions 115a to 115d are molded into a diameter slightly smaller than the battery diameter so as to apply pressure to the battery side portion to hold the battery side holding portion 115a to 115d with the partition wall portion 114 by utilizing the elastic force of the resin material. .. The degree to which the diameters of the battery side holding portions 115a to 115d are made smaller than the diameter of the battery is determined by the type of the battery, the elastic force of the resin material, and the magnitude of the pressure for holding the battery. In the case of this example, for example, ASA resin was used as the resin material, and the resin material was molded to be about 0.5 mm smaller than the diameter of the AA battery.

Coil springs 116a to 116f that come into contact with the positive electrode or the negative electrode of the battery and connect between the positive electrode or the negative electrode of the battery are attached to the battery end holding portions 113a and 113b. In order to attach the coil springs 116a to 116f to the battery end holding portions 113a and 113b, grooves 117 are formed in the battery end holding portions 113a and 113b, and the bottom portions of the coil springs 116a to 116f are fitted and attached to the grooves 117. That is, two inverted L-shaped ridges 127a and 127b are arranged to face each other on the battery end holding portions 113a and 113b, and a groove 117 is formed between the two inverted L-shaped ridges 127a and 127b. The coil springs 116a to 116f connect the coil springs so as to connect the four batteries in series. For example, as shown in FIG. 5C, the coil spring 116a on the negative electrode side and the coil spring 116b on the positive electrode side attached to the battery end holding portion 113a are formed so as to be continuous. Further, the coil spring 116c on the negative electrode side and the coil spring 116d on the positive electrode side, and the coil spring 116e on the negative electrode side and the coil spring 116f on the positive electrode side, which are attached to the battery end holding portion 113b, are formed so as to be continuous. .. The shape and connection of the coil springs 116a to 116f vary depending on the type of battery, series connection or parallel connection or series-parallel connection.

Then, openings 118a and 118b are formed in the battery end holding portion 113a at locations facing the positive electrode and the negative electrode of the battery. The tips of the negative side battery connection terminal 33 and the positive side battery connection terminal 34 protruding from the rear wall 104 of the battery case storage portion enter into the openings 118a and 118b, and come into contact with the positive electrode or the negative electrode of the battery. Further, an opening 130 is formed at the center position of the coil spring 116f on the positive electrode side of the battery end holding portion 113b. This opening 130 is used when attaching the rotating ring 112 to the lid 111.

The diameter of the lid 111 is larger than the width of the battery mounting portion 110, and the outer shape is formed in a disk shape centered on the central axis in the insertion direction of the battery case 101. The other fitting structure 119 of the battery case 101 is formed around the outer periphery of the lid 111. The other fitting structure 119 is integrally molded with the lid 11 and the resin. The other fitting structure 119 is, for example, a male screw, and is fitted to a female screw which is one fitting structure 105 formed in the vicinity of the opening 107 of the battery case storage portion 102. However, when one fitting structure 105 formed on the side wall 103 of the battery case storage portion is a male screw, the other fitting structure 119 is formed with a female screw. As described above, the other fitting structure 119 is formed corresponding to the shape of the one fitting structure 105. Therefore, if one fitting structure 105 is diagonal, curved or spiral, the other fitting structure 119 is formed correspondingly diagonally, curved or spiral.
As shown in FIG. 8, three finger holes 120a, 120b, and 120c divided in three directions are formed on the outside of the lid 111. When inserting and removing the battery case 101 into the battery case storage unit 102, insert the thumb, index finger, and middle finger into the finger holes 120a, 120b, 120c and rotate the lid 111 to store the battery case 101 in the battery case. It is stored in or taken out from the unit 102.

The other insertion guide mechanisms 121a and 121b of the battery case 101 are formed on the side surface of the battery mounting portion 110. The other insertion guide mechanisms 121a and 121b are formed on the facing surfaces of the battery mounting portion 110 corresponding to the one insertion guide mechanism 106a and 106b formed on the side wall 103 of the battery case housing portion 102 of the battery case housing portion 102. , A convex portion formed along the insertion direction of the battery case 101. Here, the other insertion guide mechanisms 121a and 121b are composed of two convex portions and are arranged line-symmetrically with respect to a line orthogonal to the center line of the battery mounting portion 110. Further, when two or more ridges are formed as the other insertion guide mechanisms 121a and 121b, the ridges have different sizes. That is, the widths of the protruding portions of the two convex portions are made different. Alternatively, the height of the protruding portion is made different. Alternatively, the width and height of the protruding portion are made different. When forming a concave portion instead of the convex portion, the width or depth of the dented portion of the concave portion, or the width and depth of the dented portion is made different. Alternatively, the shape of one convex portion or concave portion may be changed. In this case, since one of the convex portions or the concave portions has a different size or shape, the insertion direction of the battery case 101 is correct.
If one of the insertion guide mechanisms 106a and 106 has a linear shape from the opening 107 to the rear wall 104 of the battery case storage portion, the other insertion guide mechanisms 121a and 121b are also formed in a linear shape, but one of the insertion guides If the mechanisms 106a and 106 are oblique, curved or spiral, the other insertion guide mechanisms 121a and 121b are also formed correspondingly diagonally, curved or spiral. Therefore, when the battery case 101 is stored in or taken out from the battery case storage unit 102, the other insertion guide mechanisms 121a and 121b are guided by the one insertion guide mechanism 106a and 106, and the battery case 101 is the battery case storage unit. It is stored in or taken out of 102.

As described above, instead of changing the size or shape of the convex portion or the concave portion, the one insertion guide mechanism 106a and 106b formed on the inner wall of the battery case storage portion 102 is used for the battery. The other insertion guide mechanisms 121a and 121b formed on the outer wall of the battery case 101 are arranged at positions asymmetric with respect to the line orthogonal to the insertion direction of the case 101, and correspondingly, the insertion direction of the battery case 101 Place it in an asymmetrical position with respect to the line orthogonal to. That is, one of the insertion guide mechanisms 106a and 106b formed on the inner wall of the battery case storage portion 102 is arranged substantially at right angles to the line orthogonal to the insertion direction of the battery case 101, or at an arbitrary angle. Correspondingly, the other insertion guide mechanisms 121a and 121b formed in the battery case 101 are arranged substantially at right angles to the line orthogonal to the insertion direction of the battery case 101 or at an arbitrary angle. In this way, one of the insertion guide mechanisms 106a and 106b is arranged at an asymmetric position with respect to the line orthogonal to the insertion direction of the battery case 101, and the other insertion guide mechanisms 121a and 121b are correspondingly arranged in the battery case 101. Even if the battery case 101 is arranged at an asymmetrical position with respect to a line orthogonal to the insertion direction, the insertion direction of the battery case 101 can be prevented from being mistaken.

The battery case 101 includes a sliding structure portion 122 between the other fitting structure 119 and the other insertion guide mechanisms 121a and 121b. That is, the sliding structure portion 122 has a shaft 123 extending in the insertion direction of the battery case 101 formed on the central shaft of the battery case 101 in the battery mounting portion 110, and the lid 111 is rotatably fitted to the shaft 123. It is composed. More specifically, it comprises a flange 124 formed at the tip of the shaft 123 and a rotating ring 112 attached to the lid 111. The shaft 123 and the flange 124 are integrally molded with the battery mounting portion 110 by a resin material.
The rotating ring 112 is made of iron, a metal material such as stainless steel or aluminum, or a resin material, and is partially cut out to form a C shape. The inner diameter of the rotating ring 112 is larger than the shaft 123 and smaller than the flange 124. The shaft 123 is fitted into the shaft 123 through the C-shaped notch of the rotating ring 112, and the shaft 123 is fitted into the center hole 125. The rotating ring 112 is attached to and fixed to the lid 111 with three screws 126. The shaft 123 is formed longer by the thickness of the rotating ring 112 and the rotation margin, and by forming the flange 124 at the tip thereof, the lid 111 and the rotating ring 112 are free to rotate around the shaft 123, and the flange 124 is formed. Since the rotating ring 112 cannot be pulled out, the lid 111 and the rotating ring 112 are integrated with the battery mounting portion 110 to form the battery case 101.

The work process of fitting the rotating ring 112 to the shaft 123 formed in the battery mounting portion 110, mounting the lid 111, and fixing the lid 111 is as follows.

Through the formed opening 130, it is screwed into the first screw hole 131a of the lid 111. Next, the driver 129 is pulled out, and the lid 111 and the rotating ring 112 are rotated until the second screw hole 131b and the opening 130 coincide with each other. In the case of this embodiment, since there are three screw holes and the intervals are 120 °, they are rotated by 120 °. Then, the screwdriver 129 with the screw 126 is screwed through the opening 118a and the opening 130, and the screw 126 is screwed into the second screw hole 131b. This process is repeated to attach and fix the rotating ring 112 to the lid 111 with three screws 126.
In order to attach the screw 126 to the tip of the driver 129, the driver 129 may use a magnetic material, magnetize the screw 126, and magnetically attract the screw 126 made of the magnetic material. Alternatively, a pressure-sensitive adhesive such as grease may be applied to the tip of the driver 129, and the screw 126 may be adhered by this pressure-sensitive adhesive.

In this way, the lid 111 rotates and the battery mounting portion 110 operates linearly, so that the operating directions are different. However, since the battery case 101 includes the sliding structure portion 122, the lid 111 rotates. , The linear operation of the battery mounting portion 110 is performed smoothly.
Then, the old battery is removed from the battery mounting portion 110, and a new battery is attached to the battery mounting portion 110. Since the battery side pressing portions 115a to 115d are formed smaller than the diameter of the battery, the battery is pressed by the elastic force of the resin material of the battery side pressing portions 115a to 115d so that the battery does not vibrate in the battery case. Is held in. For example, even when the outer diameters of the dry batteries are different, such as alkaline batteries and manganese batteries, the batteries are held in the battery case so as not to vibrate by the battery side holding portions 115a to 115b.

Next, the battery case 101 is put into the battery case storage portion 102, and one insertion guide mechanism 106a, 106b and the other insertion guide mechanism 121a, 121b are aligned. At this time, the size of the concave portion or the convex portion, which is one of the insertion guide mechanisms 106a and 106b, is different (that is, the width of the dented portion of the concave portion is different, the depth of the dented portion is different, or the dented portion is formed. The width and depth of the protrusions are different, and the width or height of the protruding portion of the convex portion is different, or the width and height are different), and the other insertion guide mechanism 121a, 121b is the convex portion or the concave portion. Different sizes (ie, different widths or heights of the protrusions of the ridges, or different widths and heights, different widths of the dents of the ridges, different depths of the dents, or Since the width and depth of the dented portion are different), the concave portion or the convex portion, or the concave portion and the convex portion must be matched so that the width or height of the concave portion and the convex portion match. Do not make a mistake. Alternatively, one of the insertion guide mechanisms 106 and 106b and the other insertion guide mechanisms 121a and 121b are arranged asymmetrically with respect to a line orthogonal to the insertion direction of the battery case 101, and therefore must be aligned so as to correspond to each other. Do not mistake the insertion direction of the battery case 101.

Then, the thumb, index finger, and middle finger are inserted into the three finger holes 120a, 120b, and 120c of the lid 111 to rotate the lid 111, and the other fitting structure 119 formed around the outer circumference of the lid 111 and the battery case. One of the fitting structures 105 formed in the opening 107 of the storage portion 102 is fitted, and the battery case 101 is stored in the battery case storage portion 102. Since the other fitting structure 119 of the lid 111 is fitted to one fitting structure 105 of the battery case storage portion 102, the battery case 101 is fitted by one insertion guide mechanism 106a, 106b and the other insertion guide mechanism 121a, 121b. It is pushed to the rear wall 104 of the battery case storage part. Therefore, the positive and negative terminals of the battery attached to the battery case 101 pass through the openings 118a and 118b formed in the battery end holding portion 113a of the battery case 101 to store the battery case in the battery case storage portion 102. The battery connection terminal 33 on the minus side and the battery connection terminal 34 on the plus side, which protrude from the rear wall 104 of the portion, are surely in contact with each other. This contact state is maintained by the fitting of the other fitting structure 119 of the lid 111 and the one fitting structure 105 of the battery case storage portion 102. Since this holding state is also held by the insertion state of one insertion guide mechanism 106a, 106b and the other insertion guide mechanism 121a, 121b, the battery case 101 is held so as not to vibrate in the battery case storage portion 102. To.

In the first embodiment, one of the insertion guide mechanisms 106a and 106b of the battery case 101 formed in the battery case storage portion 102 is two, and is line-symmetrical with respect to a line orthogonal to the central axis of the battery case storage portion 102. However, in the second embodiment, one insertion guide mechanism 106s is one (FIG. 9). Correspondingly, in the battery case 101 of the first embodiment, the other insertion guide mechanisms 121a and 121b are two, and are arranged line-symmetrically with respect to a line orthogonal to the center line of the battery mounting portion 110. However, in the second embodiment, the other insertion guide mechanism 121s (not shown) is one. Here, in the second embodiment, the one insertion guide mechanism 106s and the other insertion guide mechanism 121s are arranged at corresponding positions so that the battery case 101 is housed in the battery case storage portion 102.
As described above, since one insertion guide mechanism 106s and the other insertion guide mechanism 121s are one, when the battery case 101 is stored in the battery case storage portion 102, the insertion angle of the battery case 101 is uniquely determined. , The insertion angle of the battery case 101 is not mistaken.
