Description

一种便携式数字录音机 技术领域
本实用新型涉及录音设备领域，具体而言，涉及一种便携式数字录音机。
背景技术
现有便携数字录音机在完成音乐会、会议、集体教学各类现场录音和视频拍摄辅助录音后，用户需将存储有录音文件的SD卡放入读卡器，或直接将录音机通过USB连接电脑，再把录音文件转存到电脑中用于备份或编辑。部分便携数字录音机具有WiFi功能可将机器内的录音文件通过点对点无线传输到手机存储。这两种做法在录制长时间现场录音时，都有可能遇到SD卡容量或手机存储空间不足的情况，导致无法完成全部的录音。另外，由于专业音频录音在大多数情况下，前期录音和后期剪辑都是由不同人员完成的，所以录音者还需要通过互联网将音频文件发送给剪辑师来进行后期编辑。这样的工作流程繁琐和效率低下，转存大文件和等待传输完成的重复性工作浪费大量时间而且不产生任何新价值，如果万一在转存时操作失误，还有可能损坏原始音频文件，导致无法挽回的后果。
随着云存储技术的普及，人们迫切需要具有WiFi直接连接云服务器进行文件自动备份功能的录音设备来帮助他们提高工作效率，消除单机存储容量受限的隐患，还能通过云服务器文件即时共享让前后期编辑协作更加顺畅和便捷。而在物联网已经开始逐渐普及的今天，现有便携数字录音机还停留在无法直接接入互联网和云服务器的时代，不能适应用户需求的变化。

为了解决现有便携数字录音机文件备份和传输的繁琐手工操作所导致的工作效率低下的问题，本实用新型提出的一种具有与外部进行通讯的新型便携数字录音机。该录音机在将声音录制在本机内部存储器上的同时，通过自带的通讯模块自动将已录制文件同步上传到专用云服务器用于备份和共享。具体地，本实用新型提供了一种便携式数字录音机，包括电源模块、音频输入模块、A/D转换模块、SoC(片上系统)核心模块、按键模块、LED指示模块、数字存储模块，其中，电源模块给音频输入模块供电和控制SoC核心模块的运行，SoC核心模块与A/D转换模块、按键模块、LED指示模块和数字存储模块连接，所述A/D转换模块与所述音频输入模块连接，所述SoC核心模块含有通讯模块，所述SoC核心模块分别与数字存 储模块以及通讯模块双向通讯。
进一步地，所述通讯模块包括WIFI通讯模块和/或蓝牙通讯模块。
进一步地，所述电源模块采用电池或者USB电源供电。
进一步地，所述音频输入模块接收外部话筒或线路音频输入，包括卡农/大三芯混合插口、小三芯插口、莲花插口。
进一步地，所述音频输入模块包括内部信号放大和供电电路，所述音频输入模块可接收舞台有线话筒、无线话筒、视频话筒、枪式话筒、领夹话筒、平衡和非平衡线路音频信号中的一种或多种。
进一步地，所述A/D转换模块将模拟音频信号转换为数字音频格式，兼容从16比特/44.1千赫到24比特/192千赫之间的各种采样率。
进一步地，所述SoC核心模块将数字音频信号录制成音频文件并存储在所述数字存储模块上。
进一步地，所述数字存储模块采用SD卡或数字闪存或硬盘。
进一步地，所述WiFi通讯模块用于与设置在互联网上的专用云服务器连接，所述蓝牙通讯模块用于手机连接。
进一步地，所述SoC核心模块每隔一段时间生成一个音频文件，再将文件存储在数字存储模块中。
本实用新型工作原理：启动电源模块打开录音机，用手机App通过蓝牙连接SoC核心模块中的蓝牙通讯模块并设置录音机要连接的WiFi连接地址和密码，连接外部话筒或电子乐器的线路信号到音频输入模块，按下按键模块的录音按键，控制SoC核心模块开始录制从音频输入模块传输到A/D转换模块的音频信号，并每隔一段时间生成一个音频文件，再将文件存储在数字存储模块中。同一时间，SoC核心模块通过内部WiFi通讯模块将已录制的音频文件自动传输到设置在互联网上的云服务器做备份存储，SoC核心模块会随时比对数字存储模块中的文件和云服务器上的文件的同步备份结果，如果出现数字存储模块容量不足时，按录音时间的先后顺序自动删除先录制的且已完全同步到云服务器的文件，为数字存储模块腾出可录音容量。
本实用新型的有益效果是：采用兼容所有话筒和线路信号的音频接口和高采样率的AD转换器，通过本机录音和云服务器同步存储，可将音乐会、会议、集体教学各类现场录音和 视频拍摄辅助录音的录音文件即时自动传输到云服务器上，有效地解决了现有录音机需要大量手工转存和传输文件的繁琐工作所带来的耗时和效率低下的问题，消除了便携录音机存储容量不足的隐患，同时也极大地方便了不在现场的音频剪辑人员同步下载录音文件并及时进行后期编辑工作。
