And the containing cavity 611 is arranged on the fixing support 61 in a penetrating manner and is provided with an upper opening and a lower opening, so that the exchange of the gas inside the containing cavity 611 and the gas outside the containing cavity 611 can be accelerated. Due to the existence of the power module 5, the temperature of the gas inside the accommodating cavity 611 is high, so that the gas with low external temperature enters the accommodating cavity 611, which is also beneficial to the heat dissipation of the power module 5.

In order to prevent the power module 5 from falling off from the accommodating cavity 611, a limiting plate is disposed at a lower end of the accommodating cavity 611, one end of the limiting plate is fixedly disposed with the lower end of the accommodating cavity 611, and is preferably integrally formed, and the other end of the limiting plate extends toward an axis of the accommodating cavity 611. The number of the limiting plates may be one or more, preferably two, and the limiting plates are symmetrically arranged at two sides of the accommodating cavity 611. The limiting plate can be in the shape of an arc. The lower end of the power module 5 is abutted against the limiting plate, and the limiting plate can prevent the power module 5 from displacing downwards along the axis of the accommodating cavity 611, so that the power module 5 is more stably mounted. And, because only two limiting plates are arranged, the contact area between the lower end of the power module 5 and the outside is larger, which is beneficial to the heat dissipation of the power module 5 and the realization of the electrical connection between the power module 5 and other elements of the microphone.

More preferably, the fixing bracket 61 may be made of metal, the metal has better thermal conductivity, the heat of the partition plate 62 can be quickly transferred to the fixing bracket 61, and because the fixing bracket 61 has a larger volume, a contact area with air is larger, so that the fixing bracket 61 can dissipate heat quickly, which is beneficial to heat dissipation of the power module 5. And the hardness of the metal is higher, the impact resistance is better, and the stable fixation of the power module 5 is facilitated. Of course, in other embodiments, the fixing bracket 61 may be made of other materials with higher hardness and better heat dissipation.

In a preferred embodiment, the cover plate is covered on the upper end of the receiving cavity 611, and the cover plate is detachably coupled to the fixing bracket 61 by a fastener. The lower side surface of the cover plate is abutted to the upper side surface of the power module 5. In order to make the power module 5 more stably installed, the lower side surface of the cover plate is formed with a limiting step, and the side surface of the limiting step is abutted to the side surface of the power module 5. The lower side surface of the cover plate can limit the power module 5 to move along the axial direction of the accommodating cavity 611, the limit step can limit the power module 5 to move along other directions, and the power module 5 can be stably fixed in the accommodating cavity 611.

Wherein, a through hole is arranged on the cover plate in a penetrating way, and the through hole is positioned at the upper side of the power module 5. That is, the air outside the cover plate can pass through the through hole to directly contact with the upper end of the power module 5, which is beneficial to heat dissipation of the power module 5 and is also beneficial to the electrical connection between the rest of the microphone on the upper side of the power module 5 and the power module 5.

In a preferred embodiment, the flexible sleeve 63 is sleeved outside the fixing bracket 61 and directly fixed with the fixing bracket 61 in an interference fit manner. The flexible cover 63 is preferably a silica gel cover, the silica gel texture is soft and light, deformation and recovery easily occur, and the silica gel has better heat conductivity, and is favorable for heat dissipation of the fixed support 61. When the microphone drops or suffers the impact, because power module 5's quality is great, consequently power module 5 suffers the impact force also great, and the silica gel cover can absorb outside impact force because the texture is soft for the impact force can't be transmitted to fixed bolster 61 with on the power module 5, power module 5 can stable install in hold in the chamber 611.

Of course, in other embodiments, the material of the flexible sleeve 63 may be other materials, such as rubber.

In a preferred embodiment, the fixing bracket 61 is detachably connected to the inside of the handle bracket 2 by a fastener, and the flexible sleeve 63 is disposed at a distance from or in abutment with the inner sidewall of the handle bracket 2, preferably at a distance, so that external impact force cannot be transmitted to the flexible sleeve 63 through the handle bracket 2.

More preferably, a knob 41 is rotatably disposed at the lower end of the handle bracket 2, the knob 41 is located at the lower side of the power module 5, a mounting hole is formed in the knob 41 in a penetrating manner, one end of the charging device can be disposed in the mounting hole, and the other end of the charging device is connected with the power module 5. But charging wire one end and outside power connection, the other end with in the mounting hole charging device connects, realizes giving power module 5 charges. The power module 5 is used for supplying power to the rest elements of the microphone.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
