The wireless microphone is composed of a cadre pocket (which can be put into the pocket, the output power is about 0.01W) and a central control. Each pocket has a different working frequency. The central control can receive voice signals of different working frequencies from each pocket at the same time. Adapt to the situation such as stage podium.
What are the good characteristics of wireless microphones?
1. Appearance modeling has a design that conforms to ergonomics and aesthetics:
The tube of a handheld wireless microphone must have the size and beautiful shape that you can hold in your hand. Generally, traditional tubes are made of bamboo or trapezoid. There is no aesthetic feeling and it is not easy to hold in your hand. Especially users who are prone to sweating are easier to grasp without slipping. The suitable shape is a double inner curve shape with a medium diameter smaller than the two ends, just like the Chinese Guanyin pin disease or a woman's waist, the shape is not only beautiful, but also easy to hold tightly.
2. The handshake microphone needs to be designed with a high invisible antenna:
The big difference between humans and monkeys is that they have no tails. Early wireless microphones had only one antenna at the end. The wireless microphone has the advantage of overcoming technical difficulties and no longer using outdated external designs. It adopts a complete invisible antenna design to make the wireless microphone easy to use, safe, and beautiful, but it will not interrupt the failure.
3. Need to assemble the excellent sound bucket 3360
The quality of the sound bucket determines the sound quality of a wireless microphone. There are two types of sound buckets: coils loaded on the vibrating membrane, dynamic loops that convert sound into electrical signals between high-density magnetic fields, and capacitive. The voice coil characteristics of this sound bucket have certain limitations. But basically the structure is simple, the price is low, and it is a popular model on the market. Condenser microphones combine electronic and structurally high-tech microphones, and use the change of the capacitor between the poles to directly convert the sound into an electrical signal with an ultra-thin gold-plated diaphragm. The important feature of a good condenser microphone is that it can show very good original sound quality. The high and low frequency response is wide and flat, high sensitivity, large directivity and dynamic range, small distortion rate, light volume, low degradation, low touch noise, and is widely used in professional equipment such as recording studios, professional stages, and testing instruments. The disadvantage is that a bias needs to be provided. However, since the wireless microphone itself is powered, the condenser head can use all the advantages of the wireless microphone to make it suitable for the wireless microphone.
4. The microphone must have the superior characteristics of low contact noise
The handshake wireless microphone will produce frictional touch noise with the palm when used, which will affect the normal sound quality. In particular, the wireless microphone itself has a sensitive preamplifier, which makes this touch noise more serious and becomes a technical bottleneck. Ordinary wireless microphones do not have professional design experience. In order to reduce manufacturing costs, simple circuits, low-cost sound buckets, poor impact suspension design, low-cost tube surface treatments, etc. are used. Even if the sound quality is not good, the obvious touch noise of the microphone cannot be overcome. , Deteriorating the original sound, therefore, when choosing a good quality wireless microphone, you must pay special attention to choosing the characteristics of good sound quality and ultra-low noise touch.
