[0004] The technical problem to be solved by the utility model is to provide an omnidirectional microphone. The existing omnidirectional microphone cannot be changed in position after being fixed during use. When the position needs to be changed, the fixing plane can only be removed, which damages the material and causes waste. The existing omnidirectional microphone has no wire protection structure, and the wire is easily damaged due to frequent changes in position.

[0005] In order to solve the above technical problems, the technical solution of the utility model is an omnidirectional microphone, comprising a microphone housing, a wire and a wind tube, the wire being connected to the rear wall of the microphone housing, the wind tube being installed on the inner wall of the microphone housing, a fixing seat being installed on the lower wall of the microphone housing, a positioning structure being installed on the lower wall of the microphone housing, a buffer structure being installed on the side wall of the microphone housing, and an auxiliary structure being mounted on the outer wall of the wire.

DETAILED DESCRIPTION

[0021] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] Example 1, please refer to Figure 1-Figure 4 An omnidirectional microphone includes a microphone housing 1, a wire 2 and a wind tube 3, the wire 2 is connected to the rear wall of the microphone housing 1, the wind tube 3 is installed on the inner wall of the microphone housing 1, a fixing seat 4 is installed on the lower wall of the microphone housing 1, a positioning structure is installed on the lower wall of the microphone housing 1, a buffer structure is installed on the side wall of the microphone housing 1, and an auxiliary structure is installed on the outer wall of the wire 2.

[0023] See also Figure 1-Figure 2 The positioning structure includes: a vacuum suction cup 5, four suction cup auxiliary blocks 6, four magnetic fixing frames 7 and four magnetic blocks 8; the vacuum suction cup 5 is installed on the lower wall surface of the fixing seat 4, the four suction cup auxiliary blocks 6 are respectively connected to the outer wall surface of the vacuum suction cup 5, the four magnetic fixing frames 7 are respectively installed on the lower wall surface of the microphone housing 1, and the four magnetic blocks 8 are respectively installed on the inner wall surfaces of the four magnetic fixing frames 7.

[0024] See also Figure 1-Figure 3The buffer structure includes: three buffer fixing plates 9, three buffer guide rods 10, three buffer guide sleeves 11 and three buffer pads 12; the three buffer fixing plates 9 are respectively installed on the outer wall surface of the microphone housing 1, the three buffer guide rods 10 are respectively installed on the lower wall surfaces of the three buffer fixing plates 9, the three buffer guide sleeves 11 are respectively sleeved on the outer wall surfaces of the three buffer guide rods 10, and the three buffer pads 12 are respectively installed on the lower wall surfaces of the three buffer guide sleeves 11.

[0025] See also Figure 1-Figure 4 The outer wall surfaces of the four buffer guide rods 10 are respectively provided with buffer reset springs 16. In this embodiment, when the three buffer reset springs 16 are reset, the microphone housing 1 is driven to move upward through the three buffer fixing plates 9, and the microphone housing 1 drives the vacuum suction cup 5 to move, and the vacuum suction cup 5 immediately leaves the smooth plane.

[0026] In this embodiment, if the fixed surface is a smooth plane, the vacuum suction cup 5 is moved to a fixed position by the fixing seat 4, and then the microphone housing 1 is pressed down to make the vacuum suction cup 5 adsorbed on the smooth plane to complete the fixation; if the fixed surface is a metal plane, the four magnetic blocks 8 are moved to a fixed position by the four magnetic fixing frames 7, and then the microphone housing 1 is pressed down to make the four magnetic blocks 8 adsorbed on the metal plane to complete the fixation.

[0027] Specifically, if the fixed surface is a smooth plane, the operator holds the microphone housing 1, drives the vacuum suction cup 5 to move to the fixed position through the fixing seat 4, and then presses down the microphone housing 1 to make the vacuum suction cup 5 adsorbed on the smooth plane to complete the fixation. During this period, the three buffer pads 12 first contact the smooth plane, and then as the microphone housing 1 is pressed down, the three buffer guide rods 10 enter the three buffer guide sleeves 11 respectively, and the three buffer reset springs 16 shrink. When the microphone housing 1 needs to be repositioned, the operator grabs the suction cup auxiliary block 6 with two fingers and pulls it upward to create a gap between the vacuum suction cup 5 and the smooth plane, and fills the outside air into the vacuum suction cup 5. At the same time, the three buffer reset springs 16 are reset. The microphone housing 1 is driven to move upward through three buffer fixing plates 9, and the microphone housing 1 drives the vacuum suction cup 5 to move, and the vacuum suction cup 5 immediately separates from the smooth plane. At this time, the operator can replace the position of the microphone housing 1. If the replacement position is a metal plane, the operator holds the microphone housing 1 and drives the four magnetic blocks 8 to move to the fixed position through four magnetic fixing frames 7. Then, the microphone housing 1 is pressed down to make the four magnetic blocks 8 adsorbed on the metal plane to complete the fixation. If the metal plane is smooth, the vacuum suction cup 5 further assists in fixation. If the metal plane is rough, the vacuum suction cup 5 and the buffer reset spring 16 assist the microphone housing 1 to separate from the metal plane when the four magnetic blocks 8 separate from the metal plane.

[0028] Example 2, please refer to Figure 4The auxiliary structure includes: an auxiliary connecting seat 13 and an auxiliary connecting sleeve 14; the auxiliary connecting seat 13 is sleeved on the outer wall surface of the wire 2 and connected to the microphone housing 1, and the auxiliary connecting sleeve 14 is sleeved on the outer wall surface of the wire 2 and is threadedly connected to the auxiliary connecting seat 13.

[0029] See also Figure 4 The outer wall surface of the conductor 2 is sheathed with an auxiliary spring 15 . In this embodiment, when the auxiliary connection sleeve 14 is separated from the auxiliary connection seat 13 , the auxiliary spring 15 contracts and resets, assisting the operator to remove the auxiliary connection sleeve 14 .

[0030] See also Figure 4 The auxiliary connecting sleeve 14 is made of soft material. In this embodiment, the soft material can bend along with the conductor 2 to extend its service life.

[0031] In this embodiment, the connection between the wire 2 and the microphone housing 1 is protected by the auxiliary connecting sleeve 14 . When the auxiliary connecting sleeve 14 is separated from the auxiliary connecting seat 13 , the auxiliary spring 15 contracts and resets, assisting the operator to remove the auxiliary connecting sleeve 14 .

[0032] Specifically, when the operator screws the auxiliary connection sleeve 14 into the auxiliary connection seat 13, the auxiliary spring 15 contracts. The auxiliary connection sleeve 14 is used to protect the connection between the wire 2 and the microphone housing 1. When the auxiliary connection sleeve 14 is damaged and needs to be replaced, the operator unscrews the auxiliary connection sleeve 14 from the auxiliary connection seat 13. When the auxiliary connection sleeve 14 is separated from the auxiliary connection seat 13, the auxiliary spring 15 contracts and resets, assisting the operator to remove the auxiliary connection sleeve 14.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
