Description

发明名称:一种车载智能 WiFi麦克风及其音频延时处理方法 技术领域
[0001] 本发明涉及车载娱乐设备技术领域, 特别涉及一种车载智能 WiFi麦克风及其音 频延时处理方法。
背景技术
[0002] WiFi全称 Wireless
Fidelity, 是一种允许电子设备连接到一个无线局域网 (WLAN) 的技术, 通常 使用 2.4G UHF或 5G SHF ISM射频频段。 几乎所有智能移动设备均支持 WiFi连接 上网, 是目前使用最广的一种无线网络传输技术。
[0003] 随着现在人们生活水平的提高, 越来越多家庭拥有了汽车, 汽车已经成为生活 中最为密切的活动空间, 人们希望在汽车中获得更加多样化的体验。 汽车一般 集成了各种各样的车载系统,如车载娱乐系统, 是指具有收音机、 影音播放功能 的娱乐系统。 随着车载系统的智能化水平越来越高, 很多车载系统也逐步开始 集成 WiFi无线网络功能模块, 能够与外部设备通过 WiFi设备进来无线通信连接
[0004] 随着智能移动设备 (例智能手机) 的兴起,人们的生活已经与智能手机密不可分 , 但是智能手机与多数的车载系统是两个完全独立的生态, 车载系统因为其特 定的产品特性和独立性, 硬件更新复杂, 成本高, 资源及软件更新起来非常麻 烦, 例如汽车上装有卡啦 OK系统, 但是面临点歌麻烦, 歌曲容量少, 曲库更新 不方便等诸多问题,本地的车载导航地图陈旧, 更新麻烦, 使用不方便等问题。 人们迫切希望智能手机与车载系统实现智能对接, 尤其是随着智能移动设备 ( 例智能手机) 的兴起, 乘客习惯于使用智能移动设备 (例智能手机) 去完成选 歌听歌, κ歌, 导航等应用。
[0005] 目前, 已经开发的一些车载麦克风设备, 一般采用 FM射频方式将麦克风的音 频信号传送到车载娱乐系统, 但是 FM调频受限于信号质量的强弱, 使其音质也 很难发挥到完美, 尤其是在干扰较多的时候, 音质基本够不成欣赏的条件; 另 外 FM调频信号抗干扰能力非常差, 在汽车行驶过程中由于信号环境差, FM调频 信号容易受干扰而产生噪声。

[0017] 为了实现双人甚至多人共同 K歌, 设置一辅助麦克风与所述车载智能 WiFi麦克 风配合, 所述辅助 WiFi麦克风包括第二主安装壳体、 第二主控电路板、 第二充 电电池以及第二麦克风, 所述第二麦克风、 所述第二主控电路板和所述第二充 电电池设置在所述第二主安装壳体内, 所述第二麦克风位于所述第二主安装壳 体的上端, 所述第二麦克风和所述第二充电电池与所述第二主控电路板电性连 接, 所述第二主控电路板上集成设置有第二主控处理器以及与所述第二主控处 理器电性连接的混音处理模块、 FM发射模块和蓝牙通信模块; 所述第二麦克风 采集外部音频信号后通过所述混音处理模块进行音频处理, 之后通过所述 FM发 射模块将所述音频信号传送到所述智能 WiFi麦克风。

[0023] 进一步的, 所述充电底座上还设有若干 USB充电接头。
[0024] 由于采用了 WiFi无线通信技术作为车载智能 WiFi麦克风与车载娱乐系统之间的 音频信号传输, 在 K歌时, 我们需要车载娱乐系统播放的伴奏或者原唱音频和麦 克风采集的音频信号尽量进行同步播放, 从而才能够获得良好地声音体验, 一 般情况下, 在汽车这样狭小的空间内, 两者之间的延时应当小于 80ms, 否则人 耳接收的声音能够明显感觉两者不同步, 从而使得 K歌效果非常差。 FM射频进 行音频信号传送时, 不与其他人设备共用数据传输通道, 因此, 在音频信号传 送过程中不会产生明显的延时问题。 但是采用 WiFi无线通信技术进行音频信号 传输时, 由于麦克风采集的音频信号进过 DSP芯片进行音频处理后产生约 20ms 的信号延时, 之后主控 MCU芯片接收 DSP芯片处理之后的音频信号, 然后将音 频信号分配给 WiFi芯片进行传送, 由于主控 MCU芯片需要处理整个麦克风各个 芯片的运行, 因此, 总是需要处理多个进程, 而这些进程处理的先后顺序一般 是根据到达主控 MCU芯片的时间来排序的, 因此音频信号在主控 MCU芯片不可 避免地产生较大的信号延时, 往往会超过 80ms, 从而影响了 K歌的效果。 为了解 决采用 WiFi无线通信技术进行音频信号传输时产生的信号延时问题, 本发明还 提供了一种音频延时处理方法, 所述方法包括以下步骤:
[0025] 创立一守护进程, 所述守护进程判断是否具有音频信号传送到主控处理器;
[0026] 当音频信号传送到所述主控处理器时, 所述守护进程暂停所述主控处理器的所 有进程, 所述主控处理器执行所述音频信号推送到 WiFi模块进行信号传输。
[0027] 进一步的, 在所述音频信号传送到所述主控处理器的步骤之前, 通过麦克风采 集所述音频信号, 通过一混音处理模块对所述音频信号进行音频处理, 所述守 护进行预先标记所述混音处理模块。
[0028] 进一步的, 所述音频延时处理方法还包括: 当车载娱乐系统接收到所述音频信 号时, 根据预先标记的唱歌模式, 所述车载娱乐系统的主控处理器优先执行所 述音频信号的播放。
发明的有益效果
有益效果 [0029] 采用上述技术方案, 由于采用了在车载麦克风中集成了 WiFi模块, 而且设置了 充电电池, 从而麦克风采集到外部音频时, 通过 WiFi模块能够将音频信息实时 传送到车载娱乐系统, 通过车载音响进行播放, 从而实现了 K歌功能, 克服了 F M发射模块容易受到干扰, 音频传输的音质低等问题。 通过 WiFi通信模块与智能 移动设备 (智能手机) 等建立了连接后, 可以将智能手机的音频资源传送到车 载娱乐系统, 实现资源共享。 另外, 车载麦克风本身具有数据存储模块, 通过 可以存储一定的音频资源, 从而在不进行 K歌, 通过智能移动设备或者按键控制 模块调用这些音频资源, 并传送到车载娱乐系统播放, 从而通过一车载麦克风 , 可以实现多种多样的车载娱乐体验。
[0030] 为了克服 WiFi模块进行音频信号传输时产生的音频延时问题, 通过软件对混音 处理模块所发送到主控处理器的音频信号进行优先处理, 可以通过创建一守护 进程来预先判断是否处于唱歌模式或者对混音处理模块 DSP进行标记, 从而能够 及时对音频信号进行传输, 避免产生太大的音频信号延时, 影响 K歌体验。 对附图的简要说明
