Abstract

The invention relates to electronic recording equipment capable of setting the recording distance, which comprises an interface for performing data interaction with outside equipment, a controller connected with the interface, a storage module connected with the controller, a microprocessor connected with the controller, a microphone for collecting voice data, and a distance setting module connected with the microprocessor, used for setting the distance and feeding information back to the microprocessor. The distance setting module comprises an infrared transmitting device and a receiving device which are arranged on a recording pen as well as an information processing unit connected with the infrared transmitting device and the receiving device respectively. The information processing unit sends an instruction which allows the infrared transmitting device to transmit a light source to the infrared transmitting device; the light source reaches a measured object, and is reflected and received by the receiving device; the receiving device sends the returned light source signal to the information processing unit; and the information processing unit converts the received information into an instruction and sends the instruction to a micro-processing unit.

Description

【Technical field】 [0001] The invention relates to an electronic device for recording, in particular to an electronic recording device capable of setting the recording distance. 【Background technique】 [0002] With the development of technology, most mobile electronic devices use flash memory (FLASH) as the storage medium, and increase the corresponding recording function, and communicate with the computer through the USB interface with the USBMASS STORAGE protocol (recognized by the computer as USB MASS STORAGEDEVICE). . In particular, digital tape recorders and digital recording pens are more and more widely used. Recording with portable electronic devices has become a frequently used function in people's daily work and life. [0003] In the process of recording with digital recording equipment, especially when it is necessary to record the sound of a speaker or a sounding device in a certain range of fixed positions, for example, it is necessary to compare the speech of ...
