Bluetooth version 5.4 has the following advantages over previous versions: 1.Higher data transfer rate. 2.Lower power consumption. 3.Longer transmission distance. 4.More stable connection. 5.Better device interoperability.
The hybrid ANC (Active Noise Cancellation) and ENC (Environmental Noise Cancellation) function is an advanced noise reduction technology used to reduce the interference of external noise on the audio experience. Traditional ANC technology captures external noise through a microphone and cancels or attenuates it through an inverse phase audio signal. However, for certain noises, such as people talking or traffic noise, conventional ANC technology cannot always completely eliminate them.
In a bluetooth headset factory, the following steps can be taken to test the Active Noise Cancellation (ANC) function
Graphene is a material composed of carbon atoms that has excellent electrical and thermal conductivity. These enable the graphene horn to produce a clearer and more accurate sound quality performance. The advantage of graphene horn is that it can provide a wider frequency response range and lower distortion rate. This means that the sound quality is closer to the original audio signal, with richer details and clearer sound.
The wiress earbud passes the RF (Radio Frequency) curve test to evaluate the performance of the earbud in wireless signal transmission. This kind of testing helps manufacturers and developers to verify the transmission quality and stability of headphones in different frequency ranges.
