Example Embodiment

[0025] Example 1

[0026] Such as figure 1 As shown, it is a principle block diagram of a sound recording method using the present invention. A sound recording method of the present invention is applied to an MP3 player 20, the MP3 player 20 includes an MP3 processing unit 1, a linear input port 2, a microphone 3, a storage unit 4, an expansion storage unit 5, a The display unit 6 and an operation input unit 7, a USB communication port 8, a headset and a linear output socket 9. Signal connection between MP3 processing unit 1 and storage unit 4, expansion storage unit 5, display unit 6, and operation input unit 7; linear input port 2 is connected to the analog-to-digital conversion module 120 in MP3 processing unit 1; microphone 3 is connected to MP3 processing The preamplifier 10 in the unit 1; the earphone and linear output jack 9 is connected to the earphone driving and linear output unit 220 in the MP3 processing unit 1.

[0027] The MP3 processing unit 1 is used to run the en...

Example Embodiment

[0036] Example 2

[0037] Such as Figure 4 Shown is a functional block diagram of a voice recording method according to another embodiment of the present invention. The preamplifier 10 can also be externally placed outside the MP3 processing unit 1. The rest of the circuit structure and principle are the same as in the first embodiment. When the front amplifier 10 is externally placed outside the MP3 processing unit 1, the input can be switched through the switch in the linear input port 2. The specific working mode is as follows Figure 5 Shown. Figure 5 It is a schematic diagram of the switch in the linear input port 2 of Embodiment 2 of the present invention. When the wireless input plug (not shown in the figure) is inserted, the A, B contacts and the C, D contacts are in a conductive state. Live music and other external sound information pass through the microphone 3, preamplifier 10, and then A, The B contact and the C and D contacts enter the MP3 processing unit 1. When ther...

Abstract

A method for recording sound includes obtaining on ¿C site music or other external sound from microphone and converting it to be electric signal, amplifying obtained sound to generate digital audio signal, generating audio file according to digital audio signal and storing audio file. In the method microphone is applied to record on ¿C site music or other external sound for ensuring quality of music instrument playing back sound.

Description

【Technical field】 [0001] The invention relates to a sound recording method and device, in particular to a sound recording method and device for recording live music and other external sounds using an MP3 player. 【Background technique】 [0002] With the development of modern information technology, some emerging technologies and new things related to the network are coming into our lives. In recent years, along with the spread of computer networks, music in MP3 (Moving Picture Experts Groupl Layer-3) data format has rapidly become popular in the network world, and MP3 players (players) are gradually becoming familiar to consumers. With the development of technology and the demand of the market, MP3 has developed from only playing MP3 music at the beginning to being able to play digital music in multiple formats at the same time, and has developed from a simple audio playback tool to an individual that integrates entertainment, learning and life. Digital music products. Exis...
