Detailed Description

Referring to fig. 1-4, an embodiment of the wireless microphone of the present invention includes a microphone body 1 and an antenna unit 2 connected to each other from top to bottom. The microphone body 1 includes a sound pickup portion 11 and a grip portion 12. The holding portion 12 has a base 121, a battery holder 122 disposed in the base 121 and configured to receive a battery, and a cover 123 detachably mounted on the base 121 and covering the battery holder 122. The switch 124 is disposed on the side of the base 121. The cover 123 is tubular in appearance, and the cover 123 is assembled to the base 121 by, for example, but not limited to, screwing.

The antenna unit 2 is coaxially disposed on the microphone body 1, and includes a transmission member 21, an antenna base 22, a housing 23, a display lamp 24, and a shielding plate 25. The transmission member 21 is mounted on the lower end of the grip 12 of the microphone body 1 and has a downward transmission hole 201, and the transmission hole 201 is, for example, but not limited to, a Type-C transmission hole 201. The antenna mount 22 is attached to the lower end of the grip portion 12.

The housing 23 is disposed on the holding portion 12 of the microphone body 1 from bottom to top and covers the transmission member 21 and the antenna base 22. The housing 23 includes a base portion 231 disposed on the holding portion 12, and an extending portion 232 extending from a surface of the base portion 231 in a direction opposite to the microphone body 1, wherein the extending portion 232 is similar to a semi-cylindrical shape in appearance and is used for the antenna base 22 to extend downward. The base portion 231 and the extension portion 232 together define a recess 233. The surface of the base portion 231 is recessed with a first opening 202 for exposing the transmission hole 201 and exposing the transmission hole 233, and a second opening 203 for emitting the light of the display lamp 24. The display light 24 is disposed on a side of the base portion 231 close to the holding portion 12 and opposite to the second opening 203, and the display light 24 is used for displaying the state of the electric quantity, such as orange when the electric quantity is insufficient, red when the electric quantity is charged, or green when the electric quantity is sufficient. The shielding plate 25 is disposed on a side of the second opening 203 away from the holding portion 12, and is made of a transparent material for transmitting light of the display light 24.

When the wireless microphone of this embodiment is used, when the display light signal 24 shows a signal with insufficient electric quantity, for example, an orange light signal, a user can insert a charging wire (not shown) into the transmission hole 201 to charge the wireless microphone, and the display light signal 24 shows a signal during charging, for example, a red light signal, and when the charging is completed, the display light signal 24 shows a signal with sufficient electric quantity, for example, a green light signal, and at this time, the user can take off the charging wire.

On the other hand, since the wireless microphone can be disposed in the battery holder 122 in a matching manner, when the electric quantity is insufficient, the user can also select to continuously supply power by replacing the battery according to circumstances, unscrew the cover 123 to separate the cover 123 from the base 121 from top to bottom, take out the old battery in the battery holder 122 and replace it with a new battery, and then install the cover 123 back to the base 121.

In the embodiment, the battery holder 122 is provided in the grip portion 12, but in another embodiment of the present invention, the battery holder 122 is not necessarily provided, and the wireless microphone may be charged only by the transmission member 21 without depending on the battery power supply.

To sum up, the utility model discloses a setting of this transmission piece 21, this wireless microphone accessible insert the charging wire and locate the transmission hole 201 of this transmission piece 21 and charge, save the inconvenience of constantly eliminating the battery of trading. Moreover, since the transmission hole 201 is exposed in the concave portion 233 of the housing 23 through the first opening 202, the transmission hole 201 can be skillfully hidden to avoid contacting the transmission hole 201 during use, and on the other hand, the wireless microphone can be disposed with the battery holder 122, so that a user can flexibly select to supply power with a battery or charge with a charging wire according to circumstances, and the wireless microphone is convenient to operate and use.
