Description

Microphone sound cavity device

Technical Field

The utility model relates to a microphone sound cavity device.

Background

A microphone typically consists of an acoustic chamber device and a housing enclosing the acoustic chamber device. The microphone acoustic cavity apparatus is an energy conversion device that picks up sound and converts the sound signal into an electrical signal. The microphone sound cavity device is used as an input, and the loudspeaker is used as an output. The sound cavity device of the microphone for long-distance use in large-scale conferences, lectures and the like has poor effect on picking up sound effects; and can only fit a circular shell, so that the appearance of the microphone is limited.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention is directed to a microphone acoustic cavity device, in which the position of a microphone head in a tube body is easily adjusted, and the microphone acoustic cavity device can improve the remote sound pickup effect by matching with through holes uniformly arranged on the tube body; furthermore, the microphone shell can be suitable for microphone shells of different shapes, and the requirement of attractiveness is met.

In order to achieve the above purpose, the technical scheme of the utility model is that: a microphone sound cavity device comprises a circular pipe body, wherein a microphone head is arranged in the pipe body, a silica gel sleeve is sleeved on the outer side of the microphone head, the silica gel sleeve is of a cylindrical structure with openings at two ends, and the microphone head is fastened in the pipe body through the silica gel sleeve; the pipe body is evenly provided with through holes. Preferably, the pipe body is a metal pipe.

The utility model discloses a microphone vocal cavity device, miaow head fasten in the body through the silica gel cover, and when thrust acted on the miaow head, the miaow head can remove the position in the body to realize the position control of miaow head. The setting of silica gel cover can also reduce the vibration noise of pickup in-process, guarantees the pickup effect. Further, the setting of the through-hole of evenly arranging can guarantee the utility model discloses a microphone sound cavity device's pickup effect is better.

The in-process of the bottom that miaow head mounted position removed from the top, miaow head formed the sound chamber when the top, and the echo chamber reduces when the bottom, removes the directionality that makes whole device from the top to the bottom and strengthens, and the directionality is stronger more, and the pickup distance of device is far away more, and the noise reduction effect of device is better. When the microphone is positioned at the top of the tube body, the microphone is suitable for scenes such as recording, singing, anchor broadcasting and the like which need close-distance pickup; when the microphone is positioned in the middle, the microphone is suitable for remote pickup scenes such as conferences, speeches and the like; when the microphone is positioned at the bottom of the tube body, the microphone is suitable for pickup scenes with longer distance such as microphone hanging in a multimedia classroom.

The microphone assembly position moves from the top to the bottom, and the sound gathering cavity formed at the top of the microphone resonates, so that the high-frequency part of a sound signal is repeatedly strengthened, the device is rich in relative high frequency, and the sound is sharp and clear. Therefore, the utility model discloses a microphone vocal cavity device, thereby the user can adjust the position of miaow head as required and satisfy needs. Because the utility model discloses a pickup effect is good, can form a complete set the microphone casing of various appearances, makes the outward appearance of microphone can satisfy more many people's aesthetic requirement.

A microphone acoustic cavity apparatus, preferably, the through-hole array is arranged. The utility model discloses in, the through-hole evenly distributed that the array was arranged can further improve the pickup effect on the body.

According to a microphone sound cavity device, preferably, the through-hole is the rectangular hole, is four rows of arrays and arranges, and equidistant arranging along the body circumference between the adjacent row.

According to a microphone sound cavity device, preferably, the miaow head is fixed in bottom, middle part or the top of body. The three positions of miaow head in the body can be applicable to different pickup distances.

A microphone sound cavity device, preferably, the one end of body is equipped with the mounting, the outside edge of body is located to the mounting. The fixing piece is symmetrically provided with a plurality of threaded holes for fixing the pipe body at the corresponding position outside.

According to microphone sound cavity device, preferably, the length of silica gel cover is not more than the miaow head. The utility model discloses a design can avoid disturbing to guarantee better pickup effect.

The utility model has the advantages that:

the utility model discloses a microphone sound cavity device has better pickup effect, has especially improved the pickup effect under the remote scene, can form a complete set the casing of various appearances, satisfies the aesthetic requirement of different users to the microphone.
