[0001] The present invention relates to a charger and a charging system.

[0003] Japanese Unexamined Patent Application Publication No. 2019-71741

[0004] By the way, when the grip portion of the microphone is inserted vertically, that is, when the microphone is charged in a standing state, a large space is required above the charger. Therefore, a charger that can insert the microphone horizontally, that is, in a lying state, has been proposed. However, in the case of a horizontal charger, depending on the insertion situation, it is difficult for the charging terminal of the microphone and the power supply terminal of the charger to make appropriate contact, so there is a risk that charging will not be properly performed.

[0005] Therefore, the present invention has been made in view of these points, and an object thereof is to enable appropriate charging even when the device to be charged is inserted horizontally into the charger.

[0006] In a first aspect of the present invention, there is provided a charger capable of charging a device to be charged, which is at least one of a microphone and a transmitter that transmits a wireless signal, the charger including a housing having a placement surface, an insertion recess provided in the housing into which the lower part of the device to be charged is inserted horizontally, a power supply unit provided in the insertion recess that contacts the charging terminal provided in the lower part to supply power, and a magnet unit provided adjacent to the power supply unit that attracts the lower part.

[0007] Further, the housing may have a first placement surface and a second placement surface orthogonal to the first placement surface, and when the first placement surface is in contact with a mounting table, the lower part of the device to be charged is inserted horizontally into the insertion recess, and when the second placement surface is in contact with the mounting table, the lower part of the device to be charged is inserted vertically into the insertion recess.

[0008] Furthermore, the insertion recess is formed to form a predetermined angle with the vertical and horizontal directions, and when the first mounting surface is in contact with the mounting base described above, the bottom side of the insertion recess may be located downwards.

[0009] Furthermore, the insertion recess may be formed by a first recess into which the microphone is inserted and a second recess wider than the first recess into which the transmitter is inserted, with the first recess forming a part of the second recess.

[0010] Furthermore, the first recess may be provided with a first power supply unit for a charging terminal located at the bottom of the microphone and a first magnetic unit for attracting the bottom of the microphone, and the second recess may be provided with a second power supply unit for a charging terminal located at the bottom of the transmitter and a second magnetic unit for attracting the bottom of the transmitter.

[0011] Furthermore, the second power supply unit may be provided on both sides of the first power supply unit, and the second magnet unit may be provided on both sides of the first magnet unit.

[0012] Furthermore, the power supply unit and the magnet unit may be provided around the bottom surface of the insertion recess, and the power supply unit may supply power by contacting the charging terminal provided at the lower part of the device to be charged.

[0013] Furthermore, a charging case containing the first battery of the microphone or the second battery of the transmitter can be inserted into the insertion recess, and the power supply unit may supply power by contacting the charging terminals of the charging case.

[0014] In a second aspect of the present invention, a charging system is provided comprising: a device to be charged, which is at least one of a microphone and a transmitter that sends a wireless signal; and a charger capable of charging the device to be charged, wherein the charger comprises: a housing having a mounting surface; an insertion recess provided in the housing into which the lower part of the device to be charged is inserted laterally; a power supply unit provided in the insertion recess and supplying power by contacting a charging terminal provided on the lower part; and a magnetic unit provided next to the power supply unit and attracting the lower part.

[0015] Furthermore, the lower part of the microphone may be provided with an antenna for wireless communication and a microphone-side magnet with the opposite polarity to the magnet part, the coil-shaped antenna may be arranged to surround the shaft member, and a magnet fixing part may be provided at the lower end of the shaft member to which the microphone-side magnet is fixed.

[0016] Furthermore, the device may further include a charging case into which the first battery of the microphone or the second battery of the transmitter can be installed, wherein the charging case with the first battery or the second battery installed can be inserted into the insertion recess, and the power supply unit may supply power by contacting the charging terminals of the charging case.

[0017] According to the present invention, the charger can properly charge the device to be charged even if it is inserted sideways.

This is a schematic diagram showing the positional relationship between the magnet part 40 and the power supply part 30. This figure shows the state in which the charging terminal of the microphone 70 and the power supply terminal are in contact. This figure shows the microphone 70. This figure shows the state in which the charging terminal of the transmitter 80 and the power supply terminal are in contact. This figure shows a modified example of the charging system S. This figure shows the charging case 90.

[0019] <Configuration of the Charging System> The configuration of the charging system S according to one embodiment will be described with reference to Figures 1 to 5.

[0020] Figure 1 is a diagram showing a charging system S according to one embodiment. Figure 2 is a perspective view of the charger 1 from the front. Figure 3 is a perspective view of the charger 1 from the rear. Figure 4 is a front view of the charger 1. Figure 5 is a diagram illustrating the usage of the charger 1. Figure 5(a) shows the charger 1 with the housing 10 positioned horizontally, and Figure 5(b) shows the charger 1 with the housing 10 positioned vertically.

[0021] As shown in Figure 1, the charging system S includes a charger 1, a microphone 70, and a transmitter 80. The charging system S is a system for charging at least one of the devices to be charged, the microphone 70 and the transmitter 80, using the charger 1.

[0022] The microphone 70 is a device that converts sound into electrical signals. The microphone 70 also functions as a transmitter that wirelessly transmits electrical signals to an external receiver. The microphone 70 is a handheld microphone with a grip portion 71 that the user holds in their hand. The microphone 70 has a rechargeable battery inside. The microphone 70 also has a charging terminal that can be connected to the power supply terminal of the charger 1. The charging terminal is located at the bottom of the grip portion 71.

[0023] The transmitter 80 is a device that wirelessly transmits electrical signals to an external receiver. The transmitter 80 also functions as a microphone capable of picking up sound. The transmitter 80 has a rechargeable battery inside. The transmitter 80 also has a charging terminal that can be connected to the power supply terminal of the charger 1. The charging terminal is located on the bottom of the transmitter 80.

[0024] Charger 1 is a device for charging the microphone 70 and the transmitter 80. Specifically, Charger 1 charges the first battery of the microphone 70 and the second battery of the transmitter 80. When the microphone 70, which has a built-in first battery, is attached to Charger 1, Charger 1 charges the first battery, and when the transmitter 80, which has a built-in second battery, is attached to Charger 1, Charger 1 charges the second battery. As shown in Figure 4, Charger 1 has a housing 10, a left insertion recess 20A, a right insertion recess 20B, a left power supply section 30A, and a right power supply section 30B.

[0025] The housing 10 is the main body of the charger 1. Inside the housing 10 are circuits for supplying power to the microphone 70 and the transmitter 80. The housing 10 has, for example, a rectangular parallelepiped shape.

[0026] The housing 10 has a surface on which it is placed, such as a table. In this embodiment, the housing 10 has multiple surfaces on which the charger 1 can be used in both horizontal and vertical orientations.

[0027] Specifically, when the housing 10 is placed horizontally, as shown in Figure 5(a), the lower surface 11a of the housing 10 becomes the first mounting surface that is placed on the mounting base 100. On the other hand, when the housing 10 is placed vertically, as shown in Figure 5(b), the rear surface 12a of the housing 10 becomes the second mounting surface that is placed on the mounting base 100. The second mounting surface is a surface perpendicular to the first mounting surface.

[0028] As shown in Figure 3, the lower surface 11a of the housing 10 is provided with lower protrusions 11b. The lower protrusions 11b contact the mounting base 100 when the charger 1 is placed on the mounting base 100 in a horizontal position. The lower protrusions 11b are projections that protrude from the lower surface 11a in a direction normal to the surface. As an example, the lower protrusions 11b are provided at the four corners of the lower surface 11a. The height of the four lower protrusions 11b is the same.

[0029] As shown in Figure 3, a rear projection 12b is provided on the rear surface 12a of the housing 10. The rear projection 12b contacts the mounting base 100 when the charger 1 is placed vertically on the mounting base 100. The rear projection 12b is a projection that protrudes from the rear surface 12a in the direction normal to the surface. As an example, the rear projection 12b is provided at the four corners of the rear surface 12a. The height of the four rear projections 12b is the same.

[0030] As shown in Figure 3, the lower surface 11a of the housing 10 is provided with two engaging recesses 11c. The two engaging recesses 11c are located at both ends of the housing 10 in the left-right direction. When the housing 10 is installed vertically on a wall or the like, the engaging recesses 11c engage with hooks provided on the wall. This makes it easier to install the charger 1 at any position on the wall.

[0031] As shown in Figure 1, the left insertion recess 20A and the right insertion recess 20B are the parts into which the microphone 70 and transmitter 80 are inserted during charging. The left insertion recess 20A and the right insertion recess 20B are recessed along the front-to-back direction from the front to the back 12a of the housing 10. In Figure 1, the microphone 70 is inserted into the left insertion recess 20A, and the transmitter 80 is inserted into the right insertion recess 20B. Specifically, the lower part of the microphone 70 is inserted sideways into the left insertion recess 20A, and the lower part of the transmitter 80 is inserted sideways into the right insertion recess 20B.

[0032] However, the above is not limited to the above; the transmitter 80 can be inserted into the left insertion recess 20A, and the microphone 70 can be inserted into the right insertion recess 20B. In other words, either the microphone 70 or the transmitter 80 can be inserted into the left insertion recess 20A, and either the microphone 70 or the transmitter 80 can be inserted into the right insertion recess 20B. For this reason, the microphone 70 may be inserted into both the left insertion recess 20A and the right insertion recess 20B.

[0033] As mentioned above, the housing 10 can be placed horizontally or vertically. When the housing 10 is placed horizontally (specifically, when the bottom surface 11a is in contact with the mounting base 100), the microphone 70 and transmitter 80 are inserted into the left insertion recess 20A and the right insertion recess 20B in a lying position. When the housing 10 is placed vertically (specifically, when the rear surface 12a is in contact with the mounting base 100), the microphone 70 and transmitter 80 are inserted into the left insertion recess 20A and the right insertion recess 20B in an upright position.

[0034] The left power supply unit 30A is located in the left insertion recess 20A, as shown in Figure 4. Specifically, the left power supply unit 30A is located on the bottom surface of the left insertion recess 20A. When the microphone 70 is inserted into the left insertion recess 20A, the left power supply unit 30A contacts the charging terminal located at the bottom of the microphone 70 to supply power. Also, when the transmitter 80 is inserted into the left insertion recess 20A, the left power supply unit 30A contacts the charging terminal located at the bottom of the transmitter 80 to supply power.

[0035] The right power supply unit 30B is located in the right insertion recess 20B, as shown in Figure 4. Specifically, the right power supply unit 30B is located on the bottom surface of the right insertion recess 20B. When the microphone 70 is inserted into the right insertion recess 20B, the right power supply unit 30B contacts the charging terminal of the microphone 70 to supply power. Also, when the transmitter 80 is inserted into the right insertion recess 20B, the right power supply unit 30B contacts the charging terminal of the transmitter 80 to supply power.

[0036] Incidentally, when the housing 10 is placed vertically, the microphone 70 and transmitter 80 are inserted vertically into the left insertion recess 20A and the right insertion recess 20B. Here, we will explain the case when the microphone 70 is inserted into the left insertion recess 20A. When the microphone 70 is inserted into the left insertion recess 20A, it tends to move downward due to its own weight. Therefore, when the housing 10 is placed vertically, the charging terminal of the microphone 70 tends to come into contact with the power supply terminal of the left power supply unit 30A, and the left power supply unit 30A can properly charge the first battery of the microphone 70. On the other hand, when the housing 10 is placed horizontally, the microphone 70 is inserted into the left insertion recess 20A lying on its side. In this case, the insertion direction of the microphone 70 is perpendicular to the vertical direction in which its own weight acts, so the microphone 70 does not tend to move within the left insertion recess 20A, and the user needs to insert the microphone 70 all the way into the left insertion recess 20A. If the microphone 70 is not inserted properly, the charging terminal of the microphone 70 will not make contact with the power supply terminal of the left power supply unit 30A, and the left power supply unit 30A will not be able to properly charge the first battery of the microphone 70.

[0037] Therefore, in this embodiment, in order to ensure that the left power supply unit 30A and the right power supply unit 30B properly supply power to the microphone 70 and transmitter 80 even when the housing 10 is placed horizontally, a magnetic unit 40 (see Figure 7) is provided to attract the microphone 70 and transmitter 80. The magnetic unit 40 is provided near the left power supply unit 30A in the left insertion recess 20A and near the right power supply unit 30B in the right insertion recess 20B. As a result, even when the housing 10 is placed horizontally, the microphone 70 and transmitter 80 are attracted to the magnetic unit 40, so that the power supply terminals of the left power supply unit 30A and the right power supply unit 30B make proper contact with the charging terminals of the microphone 70 and transmitter 80.

[0038] <Detailed Configuration of Insertion Recess, Power Supply Unit, and Magnet Unit> The detailed configuration of the insertion recess 20, power supply unit 30, and magnet unit 40 will be explained with reference to Figures 6 to 10.

[0039] Figure 6 shows the configuration of the bottom surface of the insertion recess 20. Figure 7 is a schematic diagram showing the positional relationship between the magnet part 40 and the power supply part 30. Figure 8 shows the state in which the charging terminal and the power supply terminal of the microphone 70 are in contact. Figure 9 shows the microphone 70. Figure 10 shows the state in which the charging terminal and the power supply terminal of the transmitter 80 are in contact. Note that in Figures 8 and 10, the internal configurations of the microphone 70 and transmitter 80 are simplified for ease of explanation. Also, in Figure 9, the lower case 71a of the microphone 70 (see Figure 8) has been removed.

[0040] The configurations of the left insertion recess 20A and the right insertion recess 20B are the same. Similarly, the configurations of the left power supply section 30A and the right power supply section 30B are also the same. Therefore, in the following, the left insertion recess 20A and the right insertion recess 20B will be collectively referred to as the insertion recess 20, and the left power supply section 30A and the right power supply section 30B will be collectively referred to as the power supply section 30, and the detailed configurations of the insertion recess 20 and the power supply section 30 will be described.

[0041] The insertion recess 20 is formed at a predetermined angle with respect to the vertical and horizontal directions (see FIG. 2). Specifically, the insertion recess 20 is inclined by a predetermined angle with respect to the horizontal plane such that the bottom surface side is lower in the vertical direction. For this reason, when the housing 10 is placed horizontally (when the lower surface 11a is in contact with the mounting table 100), the bottom surface side of the insertion recess 20 is located downward. In this way, the configuration in which the insertion recess 20 is formed obliquely facilitates the insertion of the microphone 70 and the transmitter 80 along the insertion recess 20 when the housing 10 is placed horizontally. Note that the present invention is not limited to the above, and the insertion recess 20 may be provided in the housing 10 so as to be parallel to the horizontal direction.

[0042] The insertion recess 20 is formed by a first recess 22 (FIG. 6) into which the microphone 70 is inserted and a second recess 25 into which the transmitter 80 is inserted. The first recess 22 is a circular recess corresponding to the outer shape of the grip portion 71 of the microphone 70, and the second recess 25 is a rectangular recess corresponding to the outer shape of the case of the transmitter 80. The second recess 25 is provided wider than the first recess 22 and surrounds the first recess 22. Specifically, the first recess 22 is located at the center of the insertion recess 20 and forms a part of the second recess 25.

[0043] As shown in FIG. 6, the power supply unit 30 is provided around the bottom surface of the insertion recess 20. Specifically, the power supply unit 30 is provided so as to be exposed from the bottom surface of the insertion recess 20. The power supply unit 30 includes a first power supply unit 32 and a second power supply unit 35.

[0044] As shown in FIG. 8, the first power supply unit 32 supplies power by contacting a charging terminal 73 provided at the lower part of the microphone 70. The first power supply unit 32 has a power supply side terminal that can contact the charging terminal 73 of the microphone 70. Here, the power supply side terminal is a power supply pin protruding from the first bottom surface 23a of the first recess 22. When the microphone 70 is mounted in the first recess 22, the power supply pin contacts the charging terminal 73.

[0045] As shown in Figure 10, the second power supply unit 35 supplies power by contacting the charging terminal 83 located at the bottom of the transmitter 80. The second power supply unit 35 has a power supply terminal that can contact the charging terminal 83 of the transmitter 80. The power supply terminal is, in this case, a power supply pin protruding from the bottom surface 33 of the second recess 25. When the transmitter 80 is mounted in the second recess 25, the power supply pin comes into contact with the charging terminal 83. As shown in Figure 6, the second power supply unit 35 is provided on both sides of the first power supply unit 32. Specifically, the second power supply unit 35 is provided in positions symmetrical to the first power supply unit 32 when viewed from the left and right.

[0046] The magnet section 40 is located in the insertion recess 20 next to the power supply section 30. Specifically, as shown in Figure 7, the magnet section 40 is located next to the power supply section 30 on the bottom surface of the insertion recess 20 when the insertion recess 20 is viewed from above. The magnet section 40 attracts the lower part of the microphone 70 or the lower part of the transmitter 80. The magnet section 40 is located around the bottom surface of the insertion recess 20. However, unlike the power supply section 30, the magnet section 40 is not exposed from the bottom surface of the insertion recess 20. Specifically, the magnet section 40 is located on the underside of the bottom surface of the insertion recess 20. The magnet section 40 has a first magnet section 42 and a second magnet section 45.

[0047] As shown in Figure 8, the first magnet portion 42 is provided in the first recess 22 and attracts the lower part of the microphone 70 inserted into the first recess 22. Specifically, the first magnet portion 42 is provided on the back side of the second bottom surface 23b of the first recess 22. The first magnet portion 42 is located on the back side of the center of the second bottom surface 23b. The second bottom surface 23, together with the first bottom surface 23a, forms the bottom surface of the first recess 22. The second bottom surface 23b is located at a lower position than the first bottom surface 23a, creating a step in the bottom surface of the first recess 22. The first magnet portion 42 is formed in a circular shape here and is larger than the first power supply portion 32.

[0048] As shown in FIG. 8, a transmitter-side magnet 72 is provided below the microphone 70. Specifically, the transmitter-side magnet 72 is provided on the back side of the lower end surface at the bottom of the microphone 70. When the microphone 70 is inserted into the first recess 22, the first magnet portion 42 faces the transmitter-side magnet 72 with the second bottom surface 23b of the first recess 22 and the lower end surface of the microphone 70 interposed therebetween. The polarity of the side of the transmitter-side magnet 72 facing the first magnet portion 42 is opposite to the polarity of the side of the first magnet portion 42 facing the transmitter-side magnet 72. Therefore, an attractive force is generated between the transmitter-side magnet 72 and the first magnet portion 42, and the lower part of the microphone 70 is attracted toward the first magnet portion 42. At this time, the power supply-side terminal of the first power supply portion 32 contacts the charging terminal 73 of the microphone 70.

[0049] A communication antenna 74 for transmitting a wireless signal to the outside is provided below the microphone 70. The communication antenna 74 has, for example, a coil shape as shown in FIG. 9 and is arranged so as to surround an antenna shaft 76 provided at the bottom of the microphone 70. The coil of the communication antenna 74 contacts the outer peripheral surface of the antenna shaft 76 and is positioned with respect to the antenna shaft 76. However, the present invention is not limited to the above, and the coil of the communication antenna 74 may not contact the outer peripheral surface of the antenna shaft 76, and there may be a gap between the coil and the outer peripheral surface. A magnet fixing portion 75 is provided at the lower end of the antenna shaft 76 on the side of the microphone 70. The magnet fixing portion 75 is an end surface of the antenna shaft 76. The transmitter-side magnet 72 is fixed to the magnet fixing portion 75 with, for example, an adhesive or a strong double-sided tape.

[0050] When the communication antenna 74 and the transmitter-side magnet 72 are located close to each other, the transmitter-side magnet 72 is attracted to the communication antenna 74, which has an adverse effect on the communication quality of the communication antenna 74. On the other hand, by providing the magnet fixing portion 75 between the communication antenna 74 and the transmitter-side magnet 72, the positional relationship between the communication antenna 74 and the transmitter-side magnet 72 is fixed, and fluctuations and biases of the magnetic flux are eliminated. This configuration suppresses a decrease in the communication quality of the communication antenna 74. As a result, the communication antenna 74 can perform communication appropriately.

[0051] The relationship between the communication antenna and the magnet will be further explained below. A coil-shaped communication antenna is affected by electromagnetic induction caused by fluctuations in magnetic flux. Therefore, it was difficult to place the magnet at the lower end of a microphone equipped with a communication antenna. In addition, in a handheld microphone equipped with a wireless transmission function, the transmitting antenna and rechargeable battery are located at the bottom of the microphone due to the shape of the microphone. Therefore, it was difficult to use a charging fixing means that utilizes the attractive force of a magnet for charging a handheld microphone. In contrast, in this embodiment, the magnet fixing part 75 fixes the transmitter-side magnet 72 to approximately the center of the communication antenna 74. Because the transmitter-side magnet 72 is fixed to the magnet fixing part 75, the magnetic flux of the transmitter-side magnet 72 is stably distributed to the center of the communication antenna 74 (specifically, the area surrounded by the coil of the communication antenna 74). Therefore, bias in the change of magnetic flux passing through the communication antenna 74 during reception is prevented, and the received radio waves are not affected by the electromagnetic induction of the transmitter-side magnet 72. In other words, since there is no bias in the radio waves caused by the magnetic flux of the transmitter-side magnet 72 distributed inside the coil forming the communication antenna 74, this embodiment does not adversely affect the sensitivity of the communication antenna 74.

[0052] As shown in Figure 10, the second magnet section 45 is provided within the second recess 25 and attracts the lower part of the transmitter 80 inserted into the second recess 25. Specifically, the second magnet section 45 is provided next to the second power supply section 35 on the underside of the bottom surface 33 of the second recess 25. As shown in Figure 7, the second magnet section 45 is provided on both sides of the first magnet section 42. Specifically, the second magnet section 45 is provided in positions symmetrical to the first magnet section 42. The second magnet section 45 is larger than the second power supply section 35 but smaller than the first magnet section 42.

[0053] As shown in Figure 10, a transmitter-side magnet 82 is provided at the bottom of the transmitter 80. Specifically, the transmitter-side magnet 82 is provided on the back side of the lower end surface of the case of the transmitter 80. When the transmitter 80 is inserted into the second recess 25, the second magnet portion 45 faces the transmitter-side magnet 82, with the bottom surface 33 of the second recess 25 and the lower end surface of the transmitter 80 in between. The polarity of the side of the transmitter-side magnet 82 facing the second magnet portion 45 is opposite to the polarity of the side of the second magnet portion 45 facing the transmitter-side magnet 82. As a result, an attractive force is generated from the transmitter-side magnet 82 toward the second magnet portion 45, and the lower part of the transmitter 80 is attracted toward the second magnet portion 45. At this time, the power supply terminal of the second power supply unit 35 comes into contact with the charging terminal 83 of the transmitter 80.

[0054] <Modification> In the charging system S described above, a microphone 70 containing a first battery and a transmitter 80 containing a second battery are inserted into the left insertion recess 20A and right insertion recess 20B of the charger 1, and the first battery and the second battery are charged. However, the system is not limited to this, and the first battery and the second battery may be charged by the charger 1 via the charging case described below.

[0055] Figure 11 shows a modified example of the charging system S. Figure 12 shows the charging case 90. Figure 12(a) shows the charging case 90 with the first battery 77 of the microphone holon 70 installed, and Figure 12(b) shows the charging case 90 with the second battery 87 of the transmitter 80 installed.

[0056] In the modified version, a charging case 90 equipped with the first battery 77 or the second battery 87 can be attached to the insertion recess 20 of the charger 1. In Figure 11, a charging case 90 with the first battery 77 attached is attached to the left insertion recess 20A.

[0057] The charging case 90 is a dedicated case for mounting the first battery 77 or the second battery 87. The charging case 90 has a first mounting section 91 into which the first battery 77 is mounted, and a second mounting section 92 into which the second battery 87 is mounted. Here, a part of the first mounting section 91 and a part of the second mounting section 92 overlap, which makes it possible to miniaturize the charging case 90. As a result, the first battery 77 and the second battery 87, which have significantly different shapes, can be mounted in the small charging case 90.

[0058] Furthermore, the charging case 90 has case terminals that connect to the terminals of the installed first battery 77 or the terminals of the second battery 87. In addition, a charging terminal is provided at the bottom of the charging case 90. This charging terminal is connected to the power supply side terminal of the power supply unit 30 (here, the left power supply unit 30A) when the charging case 90 is installed in the insertion recess 20 (here, the left insertion recess 20A). As a result, the power supply unit 30 can charge the first battery 77 or the second battery 87 installed in the charging case 90 via the charging terminal and the case terminal.

[0059] <Effects of this embodiment> The charger 1 of the above-described embodiment has an insertion recess 20 into which the lower part of the device to be charged is inserted horizontally, a power supply unit 30 provided in the insertion recess 20 that contacts the charging terminals provided at the lower part to supply power, and a magnet unit 40 provided next to the power supply unit 30 that attracts the lower part. As a result, when the microphone 70 and transmitter 80 are inserted horizontally (lying down) into the insertion recess 20, the magnet unit 40 attracts the lower part of the microphone 70 and transmitter 80, so that the power supply terminal of the power supply unit 30 can be properly connected to the charging terminals of the microphone 70 and transmitter 80. As a result, even when the housing 10 is placed horizontally, the charger 1 can properly charge the microphone 70 and transmitter 80.
