[0060] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0061] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0062] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0063] Embodiment 1:

[0064] See also Figure 1-Figure 2 The embodiment of the utility model provides a forward and reverse microphone charging structure, including a speaker 10 and a microphone 20, the speaker 10 is provided with a receiving slot 11 corresponding to the number of the microphones 20, the microphones 20 are placed in the receiving slots 11, a circuit board for charging the microphones 20 is arranged in the speaker 10, a plurality of charging pins 12 electrically connected to the circuit board are arranged in the receiving slot 11, and a plurality of annular charging contact pieces 21 matching the charging pins 12 are arranged around the outer periphery of the microphone 20, so that after the microphone 20 is accommodated in the receiving slot 11 in the forward or reverse direction, the annular charging contact piece 21 is electrically connected to the charging pin 12 and charges the microphone 20.

[0065] The embodiment of the utility model provides a forward and reverse microphone charging structure. Since a plurality of the annular charging contact pieces 21 are arranged around the outer periphery of the microphone 20, when the user places the microphone 20 in the receiving slot 11, there is no need to deliberately adjust the insertion direction and placement position of the microphone 20 in the receiving slot 11. The annular charging contact piece 21 of the microphone 20 in any direction can contact and energize the charging pin 12 in the receiving slot 11. The utility model uses the annular charging contact piece 21 as a contact point. The overall contact area of ​​the annular charging contact piece 21 is large. The user can place the microphone 20 in the receiving slot 11 forward and reverse to achieve charging. There is no need to place the microphone 20 in a specific direction, which is convenient for the user's charging operation and improves the user's experience.

[0066] In this example, see Figure 2-Figure 3 The plurality of annular charging contact pieces 21 include a first charging piece 210 , a second charging piece 211 and a third charging piece 212 .

[0067] Among them, the first charging sheet 210 is arranged in the middle of the microphone 20, and the polarity of the first charging sheet 210 is negative. The second charging sheet 211 and the third charging sheet 212 are respectively arranged on both sides of the first charging sheet 210, and the polarity of the second charging sheet 211 and the third charging sheet 212 are both positive.

[0068] The plurality of charging pins 12 include a first charging pin 120 , a second charging pin 121 and a third charging pin 122 , and the positions of the first charging pin 120 , the second charging pin 121 and the third charging pin 122 correspond to the first charging plate 210 , the second charging plate 211 and the third charging plate 212 respectively.

[0069] The polarities of the first charging pin 120 , the second charging pin 121 , and the third charging pin 122 are negative, positive, and positive, respectively.

[0070] Specifically, Figure 2 and Figure 3 For example, when the microphone 20 is placed into the receiving groove 11 in a forward or reverse direction, the first charging pin 120 as the negative pole is aligned and connected with the first charging sheet 210 as the negative pole.

[0071] Regarding the positive pole, when the microphone 20 is placed forwardly into the receiving slot 11, the second charging pin 121 as the positive pole is aligned and connected with the second charging sheet 211; the third charging pin 122 as the positive pole is aligned and connected with the third charging sheet 212. At this time, charging can be performed.

[0072] When the microphone 20 is reversely placed into the receiving slot 11, the second charging pin 121 as the positive pole is aligned and connected with the third charging sheet 212; the third charging pin 122 as the positive pole is aligned and connected with the second charging sheet 211. At this time, charging is also possible.

[0073] Specifically, Figure 3 When the head of the microphone 20 faces right, the microphone 20 is placed upright. When the head of the microphone 20 faces left, the microphone is placed reversely.

[0074] See also Figure 3-Figure 6 In this embodiment, the first charging piece 210, the second charging piece 211 and the third charging piece 212 are fully enclosed annular charging contact pieces 21 or non-fully enclosed annular charging contact pieces 21. The fully enclosed or non-fully enclosed first charging piece 210, the second charging piece 211 and the third charging piece 212 of this embodiment have large areas and do not need to be specially aligned. The user can put the microphone 20 into the receiving groove 11 in both directions to achieve the corresponding electrical connection between the first charging piece 210, the second charging piece 211 and the third charging piece 212 of the annular charging contact piece 21 and the first charging piece 210, the second charging piece 211 and the third charging piece 212 of the charging pin 12, thereby achieving charging of the microphone 20.

[0075] It should be noted that the fully enclosed annular charging contact piece 21 of this embodiment is an annular charging contact piece 21 that fully covers the outer surface of the microphone 20; the half-enclosed annular charging contact piece 21 is an annular charging contact piece 21 that partially covers the outer surface of the microphone 20.

[0076] Furthermore, the outer circumferences of the first charging piece 210, the second charging piece 211, and the third charging piece 212 are all surrounded by a plurality of annular protrusions 22, and two adjacent annular protrusions 22 are formed with a clamping groove 23 for clamping the first charging pin 120, the second charging pin 121, and the third charging pin 122. The clamping groove 23 is formed by providing a plurality of annular protrusions 22. When the first charging piece 210, the second charging piece 211, and the third charging piece 212 of the microphone 20 are respectively in contact with the first charging pin 120, the second charging pin 121, and the third charging pin 122, the first charging pin 120, the second charging pin 121, and the third charging pin 122 are respectively clamped in the clamping groove 23, so that the microphone 20 is clamped during shaking, the connection stability is ensured, and the microphone 20 is prevented from accidentally falling off.

[0077] Of course, in other embodiments of the present invention, a plurality of first adhesive stickers 24 are arranged around the periphery of the microphone 20, and a second adhesive sticker 13 is arranged in the receiving groove 11. The first adhesive sticker 24 and the second adhesive sticker 13 are arranged to match each other, so that after the microphone 20 is placed in the receiving groove 11, the first adhesive sticker 24 and the second adhesive sticker 13 are bonded to make the microphone 20 closely fit in the receiving groove 11, thereby ensuring the stability of the microphone 20 during charging and preventing the microphone 20 from being separated from the receiving groove 11.

[0078] In this embodiment, the contour line of the contact portion between the microphone 20 and the receiving groove 11 is a left-right symmetrical structure, and the microphone 20 is placed forward or reversely in the receiving groove 11. The receiving groove 11 of this embodiment is a groove recessed on the speaker 10, and the receiving groove 11 is for the microphone 20 to be inserted and is gap-matched with the microphone 20. Specifically, the receiving groove 11 of this embodiment is provided with two, and the two receiving grooves 11 are arranged side by side, so that the speaker 10 can charge two microphones 20 at a time, and the contour line of the contact portion between the microphone 20 and the receiving groove 11 is a left-right symmetrical structure, so that the microphone 20 is placed forward or reversely in the receiving groove 11.

[0079] In this embodiment, the charging thimble 12 is connected to the inside of the speaker 10 and passes through the speaker 10 and is inserted into the receiving slot 11. The charging thimble 12 of this embodiment is a thimble made of steel, copper or gold-plated copper. The charging thimble 12 is preferably a pogo pin charging thimble 12. In other embodiments of the utility model, the charging thimble 12 may be a charging thimble 12 other than a pogo pin, which is not specifically limited in this embodiment.

[0080] In this embodiment, the depth of the receiving groove 11 is 2 / 4 to 3 / 4 of the thickness of the microphone 20, so that the microphone 20 can be partially accommodated in the receiving groove 11. Specifically, since the depth of the receiving groove 11 is 2 / 4 to 3 / 4 of the thickness of the microphone 20, it can effectively ensure that the microphone 20 is sufficiently embedded, and the structure after embedding can be ensured to be stable and the charging contact is reliable.

[0081] Of course, in other embodiments of the present invention, the microphone 20 is completely received in the receiving slot 21. Since the microphone 20 is completely received in the receiving slot 21, the microphone 20 can be completely fixed in the receiving slot 21 during the charging process, ensuring stable contact during the charging process.

[0082] It should be noted that this embodiment does not limit the number of the receiving slots 11 and the microphones 20 , and the number of the receiving slots 11 and the microphones 20 may be one, two, or three or more.

[0083] Embodiment 2:

[0084] See also Figure 2-3 This embodiment is basically the same as Embodiment 1, except that:

[0085] The plurality of annular charging contact pieces 21 include a first charging piece 210 , a second charging piece 211 and a third charging piece 212 .

[0086] Among them, the first charging sheet 210 is arranged in the middle of the microphone 20, and the polarity of the first charging sheet 210 is negative. The second charging sheet 211 and the third charging sheet 212 are respectively arranged on both sides of the first charging sheet 210, and the polarity of the second charging sheet 211 and the third charging sheet 212 are both positive.

[0087] The plurality of charging pins 12 include a first charging pin 120 , a second charging pin 121 and a third charging pin 122 , and the positions of the first charging pin 120 , the second charging pin 121 and the third charging pin 122 correspond to the first charging plate 210 , the second charging plate 211 and the third charging plate 212 respectively.

[0088] The polarities of the first charging pin 120 and the second charging pin 121 are negative and positive respectively.

[0089] The third charging pin 122 is an enabling control terminal.

[0090] When the microphone 20 is placed into the receiving groove 11 in a forward or reverse direction, the first charging pin 120 as the negative pole is aligned and connected with the first charging sheet 210 as the negative pole.

[0091] Regarding the positive pole, when the microphone 20 is placed forwardly into the receiving groove 11, the second charging pin 121 serving as the positive pole is aligned with and connected to the second charging sheet 211; the third charging pin 122 serving as the enabling control end is aligned with and connected to the third charging sheet 212.

[0092] When the microphone 20 is reversely placed into the receiving groove 11, the second charging pin 121 serving as the positive pole is aligned with and connected to the third charging piece 212; the third charging pin 122 serving as the enabling control end is aligned with and connected to the second charging piece 211.

[0093] Therefore, no matter it is placed right side up or down side down, the positive and negative electrodes of the microphone 20 can correspond to the positive and negative electrodes in the receiving slot 12, thereby achieving charging.

[0094] It can also be seen that, no matter it is placed right side up or down side down, the electrode properties of the pins aligned and connected by the third charging pin 122 as the enabling control end are all positive. At this time, the third charging pin 122 as the enabling control end is connected to the circuit board, and the circuit board detects whether the microphone 20 is placed in the receiving slot 11 through the third charging pin 122 as the enabling control end.

[0095] The following example illustrates the role of the enable control terminal. Specifically, when the circuit board is set to detect a high level through the third charging pin 122, it is determined that the microphone 20 is placed in. The high level at this time comes from the battery in the microphone 20. Then, the circuit board controls the first charging pin 120 and the second charging pin 121 to start charging the microphone 20. If the microphone 20 is not detected to be placed in, the first charging pin 120 and the second charging pin 121 can be controlled not to supply power. At this time, the charging circuit (not shown) connected to the first charging pin 120 and the second charging pin 121 is in a dormant state, thereby saving some energy consumption.

[0096] It should be noted that the microphone 20 needs to be charged when the battery is low, but the battery does not mean that the power is 0 at this time, it is just that the power is insufficient to supply the microphone 20 to work normally, and the battery can still be discharged so that the circuit board detects a high level through the third charging pin 122. Generally speaking, only microampere current is needed to trigger a high level, so as long as the battery is not damaged, the current board can be triggered to charge the microphone 20 when the battery is low.

[0097] Alternatively, the plurality of charging pins 12 include a first charging pin 120 and a second charging pin 121 , and the positions of the first charging pin 120 and the second charging pin 121 correspond to the first charging piece 210 and the second charging piece 211 respectively.

[0098] The polarities of the first charging pin and the second charging pin are negative and positive respectively.

[0099] When the microphone 20 is placed forwardly or reversely into the receiving slot 11, the first charging pin 120 as the negative pole is aligned and connected with the first charging sheet 210. The second charging pin 121 as the positive pole is aligned and connected with the second charging sheet 211 or the third charging sheet 212 as the positive pole, so that the speaker 10 can charge the microphone 20.

[0100] Embodiment 3:

[0101] See also Figure 2-3 This embodiment is basically the same as Embodiment 1, except that:

[0102] The plurality of annular charging contact pieces 21 include a first charging piece 210 , a second charging piece 211 and a third charging piece 212 .

[0103] Among them, the first charging sheet 210 is arranged in the middle of the microphone 20, and the polarity of the first charging sheet 210 is positive. The second charging sheet 211 and the third charging sheet 212 are respectively arranged on both sides of the first charging sheet 210, and the polarities of the second charging sheet 211 and the third charging sheet 212 are respectively negative.

[0104] The plurality of charging pins 12 include a first charging pin 120 , a second charging pin 121 and a third charging pin 122 , and the positions of the first charging pin 120 , the second charging pin 121 and the third charging pin 122 correspond to the first charging plate 210 , the second charging plate 211 and the third charging plate 212 respectively.

[0105] The polarities of the first charging pin 120 and the second charging pin 121 are positive and negative respectively.

[0106] The third charging pin 122 is an enabling control terminal.

[0107] When the microphone 20 is placed into the receiving groove 11 in a forward or reverse direction, the first charging pin 120 serving as the positive pole is aligned with and connected to the first charging sheet 210 .

[0108] When the microphone 20 is placed forward, the second charging pin 121 as the negative pole is connected to the second charging sheet 211 , and the third charging pin 122 as the enabling control terminal is connected to the third charging sheet 212 as the negative pole.

[0109] When the microphone 20 is placed in reverse, the second charging pin 121 as the negative pole is connected to the third charging sheet 212, and the third charging pin 122 as the enabling control terminal is connected to the second charging sheet 211 as the negative pole.

[0110] It can be seen that no matter it is placed right side up or upside down, the positive and negative electrodes of the microphone 20 can correspond to the positive and negative electrodes in the receiving slot 12, thereby achieving charging.

[0111] It can also be seen that, no matter it is placed right side up or inverted, the electrode properties of the pins aligned and connected by the third charging pin 122 as the enabling control end are all negative. At this time, the third charging pin 122 as the enabling control end is connected to the circuit board, and the circuit board detects whether the microphone 20 is placed in the receiving slot 11 through the third charging pin 122 as the enabling control end.

[0112] The following example illustrates the function of the enabling control terminal. Specifically, in this embodiment, when the circuit board is set to be triggered by the third charging pin 122 at a low level, it is determined that the microphone 20 is placed. At this time, the circuit board is always discharged. When the microphone 20 is placed, the circuit board detects that the output electric energy is released through the third charging pin 122, so the circuit board can determine that the microphone 20 is placed. Then, the circuit board controls the first charging pin 120 and the second charging pin 121 to start charging the microphone 20. When the microphone 20 is not detected to be placed, the first charging pin 120 and the second charging pin 121 can be controlled not to supply power. At this time, the charging circuit (not shown) connected to the first charging pin 120 and the second charging pin 121 is in a dormant state, thereby saving some energy consumption.
