Embodiments of the present disclosure are not necessarily intended to include all aspects of the invention. It should be appreciated that the various concepts and embodiments described above, as well as those described in greater detail below, may be implemented in any of numerous ways, as the disclosed concepts and embodiments are not limited to any implementation. Additionally, some aspects of the present disclosure may be used alone or in any suitable combination with other aspects of the present disclosure.
As shown in fig. 1-2, a page-turning stylus with two microphones comprises a main body casing 1, keys arranged on the main body casing 1 and an internal circuit arranged in the main body casing 1, wherein the keys comprise an up-turning key 3, a down-turning key 4, a microphone on-off key 6, a mouse key 5 and a laser light on-off key 2, a micro charging port is arranged at the side of the main body casing 1, the page-turning stylus also comprises two microphones arranged in the main body casing 1, the two microphones comprise a noise-reducing microphone and a recording sound microphone, external noise can be filtered through the arrangement of the two microphones, and when the sound is discontinuous or low, the condition that important sound information is missed is avoided, and the use effect is improved. When the voice-recording microphone is used, the voice is collected by the voice-recording microphone in the main body shell 1, noise is collected by the noise-reducing microphone in the main body shell 1, and then the noise doped in the voice is eliminated through hard software signal processing and comparison, so that the effect of improving the communication quality is achieved. The principle is to provide a noise reduction microphone and a recording sound microphone, wherein the recording sound microphone is a main microphone for picking up the voice of a user, the noise reduction microphone is a background sound pickup microphone which is usually installed at the bottom inside the main body casing 1, and the noise reduction microphone and the recording sound microphone are isolated by a main board inside. During normal voice playing, the mouth is close to a recording sound microphone, the recording sound microphone generates a larger audio signal Va, meanwhile, the noise reduction microphone obtains a plurality of voice signals Vb more or less, but the voice signals are much smaller than Va, the two signals are input into a microphone processor, the input ends of the two signals are provided with a differential amplifier, namely, the two signals are subtracted and then amplified, and then the obtained signal is Vm-Va-Vb. If there is background noise in the using environment, because the sound source is far away from the main body casing, the intensity of the sound wave is almost the same when reaching the two microphones of the main body casing, namely Va ≈ Vb, so for the background noise, although both microphones pick up, Vm ═ Va-Vb ≈ 0, and then can effectively resist the ambient noise interference around the page-turning stylus pen, greatly improving the definition of the using sound quality.
