Description

[0001] WIRELESS MICROPHONE TRANSMISSION DEVICES [0002]

The present invention relates to a wireless microphone transmitting apparatus.

Generally, in case of lecturing or speaking to a large number of people in a large space in an indoor or outdoor environment, a microphone may be used to amplify the voice signal of the lecturer and improve the information transmitting power.

The microphone device has a wired microphone and a wireless microphone.

A wired microphone is a microphone device that is directly connected to a speaker or other output device by a cable. Although wired microphones are relatively simple to configure and inexpensive compared to wireless microphones, there is a drawback in that the cable that connects the wired microphone and the output device is limited by the radius of the instructor's activity.

Wireless microphones have been used to compensate for the above mentioned disadvantages of wired microphones, removing cables that are directly connected to the output device. Accordingly, the wireless microphone must additionally include a transmitting device and a receiving device. That is, when a transmitting apparatus connected to a wireless microphone converts a user's acoustic signal into a wireless signal and transmits the wireless signal, the receiving apparatus connected to the output apparatus receives the wireless signal and supplies the wireless signal to the output apparatus.

In addition, in the case of using a wireless microphone, it is common for the instructor to fix the microphone and / or the transmitting device connected thereto to the top and the belt, respectively, in order to freely use the two hands. However, there is a problem in that noise signals are micro-influenced due to friction between the microphone and the clothes, which occurs according to the movement of the instructor or the movement of the instructor as the microphone is closely attached to the body.

The microphone 100 includes a discontinuous multi-stage rotation unit 110, a firing continuous rotation unit 130, an elastic continuous rotation unit 150, (Not shown).

The discontinuous multi-stage turning unit 110 is connected to the radio transmitter 200.

One end of the discontinuous multi-stage rotation unit 110 is connected to the radio transmitter 200, and the firing continuous rotation unit 130 is connected to the other end.

The discontinuous multi-stage turning unit 110 can be folded at a plurality of discontinuous angles.

The discontinuous multi-stage turning unit 110 can be folded only at any one of a plurality of predefined angles. That is, the discontinuous multi-stage rotation unit 110 can not be collapsed at angles other than a plurality of predefined angles. Here, the plurality of predefined angles may be set at intervals of 30 degrees with respect to each other.

The discontinuous multi-stage turning unit 110 can extend the life of the wireless microphone transmitting apparatus 10, in particular, the firing continuous rotation unit 130. In the case where the discontinuous multi-stage rotary unit 110 is not provided in the wireless microphone transmission apparatus 10 and the position of the microphone unit 170 is set only by the firing continuous rotation unit 130, The fatigue phenomenon due to excessive deformation as shown in Fig. That is, the firing continuous rotation unit 130 can be deformed by gravity due to the fatigue phenomenon. However, in this embodiment, since the discontinuous multi-stage rotation unit 110 as well as the firing continuous rotation unit 130 are provided, the user can easily recognize the state of the microphone unit 170 by the discontinuous multi-stage rotation unit 110, After the approximate position is set, the accurate position of the microphone unit 170 can be set by the firing continuous rotation unit 130. As a result, it is possible to increase user convenience and to prevent excessive deformation of the firing continuous rotation unit 130, thereby extending the service life of the device.

The firing continuous rotation unit 130 is connected to the discontinuous multi-stage rotation unit 110.

One end of the firing continuous rotation unit 130 is connected to the discontinuous multi-step rotation unit 110, and the other end thereof is connected to the elastic continuous rotation unit 150. [

The firing continuously rotating portion 130 can be folded at a continuous arbitrary angle.

Unlike the discontinuous multi-stage rotation unit 110, the firing continuous rotation unit 130 has no predetermined angle and can be folded at an arbitrary angle desired by the user.

The firing continuous rotation portion 130 is plastically deformed, so that it can be folded at an arbitrary angle. To this end, the firing continuous rotation unit 130 may have a degree of firing such that it can be permanently deformed by the force applied by the user.

The elastic continuous rotation part 150 is connected to the firing continuous rotation part 130.

One end of the elastic continuous rotation unit 150 is connected to the plastic continuous rotation unit 130, and the other end of the elastic continuous rotation unit 150 is connected to the microphone unit 170.

The elastic continuous rotation unit 150 can be folded at an arbitrary angle desired by the user like the firing continuous rotation unit 130. [ In addition, the elastic continuous rotation part 150 can be stretched to a desired length by the user within the elastic range.

The elastic continuous rotation portion 150 is elastically deformed, so that it can be folded at an arbitrary angle. The elastic continuous rotation unit 150 can be restored to its original position when the external force is removed. As a result, the user can adjust the position of the microphone unit 170 elastically by the elastic continuous rotation unit 130 without permanently changing the position of the microphone unit 170 according to circumstances such as temporarily changing the posture. For this purpose, the elastic continuous rotation unit 150 may have elasticity enough to be elastically deformed by a force applied by the user.

The microphone unit 170 is connected to the elastic continuous rotation unit 150.

The microphone unit 170 receives the sound signal, converts the sound signal into an electrical signal, and transmits the electrical signal to the wireless transmitter 200.

The microphone unit 170 can be wired to the wireless transmitter 200 by a cable and the cable connecting between the microphone unit 170 and the wireless transmitter 200 is connected to the elastic continuous rotation unit 150, And the interior of the discontinuous multi-stage rotary part 110 in order.

The microphone unit 170 may be a directional microphone.

The microphone unit 170 is directional microcomputer, so that noise signals other than the acoustic signal can be minimized through the microphone unit 170.

It is very important to precisely adjust the position of the microphone unit 170 when the microphone unit 170 is made of directional microphones. The user can precisely adjust the position of the microphone unit 170 by the discontinuous multi-stage rotation unit 110 and the plastic continuous rotation unit 130 as described above. In addition, the user can elastically adjust the position of the microphone unit 170 by the elastic continuous rotation unit 150 without permanently changing the position of the microphone unit 170 when temporarily changing the posture.

The radio transmitter 200 converts an electric signal into a radio signal and transmits the radio signal.

For this purpose, the wireless transmitter 200 may include a signal converting unit for converting an electric signal inputted from the microphone unit 170 into a wireless signal, and a wireless transmitting unit for wirelessly transmitting the wireless signal.

The fixed clamp 300 is formed on one side of the wireless transmitter 200.

The fixed gripper 300 is a component for fixing the radio transmitter 200 to an object such as a user's body, a musical instrument body, or the like.

The fixed clamp 300 may be coupled to one side of the wireless transmitter 200 so as to be rotatable at a certain angle. For example, the fixed gripper 300 may be coupled to one side of the wireless transmitter 200 to be rotatable 360 degrees. The rotation angle of the fixed clamp 300 can be adjusted at intervals of 30 degrees. That is, the fixed clamp 300 may be rotated at 0 °, 30 °, 60 °, 90 °, etc. with respect to the wireless transmitter 200. As a result, the user can rotate the fixed grip 300 according to the position and shape of the object to be fixed.

The buffering protrusion 310 may protrude from the clamping surface of the fixed clamp 300, i.e., the surface of the fixed clamp 300 that is in close contact with the object to be clamped.

The buffering protrusion 310 is made of an elastic material.

The buffering protrusion 310 allows the fixed clamp 300 to be easily attached even when the surface of the object to be clamped is not uniform and the noise signal other than the acoustic signal is prevented from flowing through the fixed clamp 300 .

The buffering protrusions 310 may be formed in parallel in plural and may have a triangular sawtooth shape.

The guide protrusion 113 is formed in the longitudinal direction of the first frame 111 to guide the sliding member 119 in the longitudinal direction of the first frame 111 in cooperation with the guide groove 121. As a result, while the sliding member 119 is slid inside the first frame 111, the angle adjusting protrusion 120 of the sliding member 119 can be easily reinserted even if it is detached from the through hole 114 .

The other end of the first frame 111 may be provided with a through hole 114 through which the angle adjusting protrusion 120 of the sliding member 119 can enter and exit, as shown in FIG.

The elastic member 127 may be an elastic spring.

The guide groove 121 formed in the side surface of the sliding member 119 cooperates with the guide protrusion 113 protruding from the inner side surface of the first frame 111 to slide the sliding member 119 in the first frame 111 Guide in the longitudinal direction.
