Description

Technical Field

[0001] The utility model relates to the technical field of microphones, in particular to a dual-purpose wireless microphone with a PPT control function that can be hung on an ear or held in a hand. Background Art

[0002] With the rapid development of semiconductor, integrated circuit, radio communication and other technologies, miniaturization and low power consumption of portable products have become a trend. This is especially true for wireless microphones in teaching sound reinforcement applications. Since there are certain requirements for the real-time sound quality, transmission stability and battery life of the product, the existing technology needs to balance these factors. For example, traditional microphones are connected to the audio host by wire. Wired microphones have good sound quality and do not have transmission stability and battery life issues. However, the constraints of wires cause many inconveniences when using them.

[0003] The wireless microphone developed in recent years adopts the wireless transmission method, which is sampled and transmitted by the transmitter, and a receiver is installed on the host end of the audio system to restore the sound. Due to the characteristics of wireless microphone signal transmission, the higher the sound quality, the greater the required data transmission volume and power consumption, and its sound quality and battery life are inversely proportional. Therefore, increasing the battery life often requires increasing the battery capacity, which makes the microphone bulky and not conducive to long-term use by users. On the other hand, if the battery capacity is too small, the battery life is insufficient, and the battery needs to be charged before it can be used again. Therefore, although the current wireless microphone solves the constraints of wired connection, it is limited by the size of the battery capacity, and there are some shortcomings such as bulky appearance or insufficient battery life. In addition, the existing wireless microphones have relatively simple functions, and cannot realize the function of controlling the up and down pages of PPT, nor do they have the function of laser.
