Description

一种麦克风音箱一体设备 技术领域
[0001] 本发明涉及音频播放领域， 更具体地说， 涉及一种麦克风音箱一体设备。
背景技术
[0002] 卡拉 0K技术及应用非常广泛而成熟， 但便携式的简化设备不多， 个体化的卡 拉 OK产品更是极少， 只有在专业场所或者固定场所使用， 十分不便， 而现有各 种麦克风包括自带卡拉 OK混响功能的麦克风技术成熟， 应用广泛， 但通常只是 作为单独麦克风产品， 需要外接音箱或其它设备配合才能使用。 因音箱会随着 声音产生和声音频率相同的振动， 当麦克风和音箱为一体或者紧紧靠近的吋候 ， 从麦克风输入的声音经音箱放大后又经外壳传递到麦克风， 这吋麦克风再次 将这一相同频率的声音输入并再次放大， 经过多次反复放大， 于是产生强烈地 自反馈效应， 即自激效应， 这吋音箱里便发出持续地， 不断加强地相同频率的 声音 （俗称啸叫） ， 完全破坏了正常的使用。
[0003] 当然， 也有一些设计， 将声音的频率进行变化处理， 使输入的声音频率或者频 相与输出的频率或频相不一样， 从而避免啸叫的发生； 或者通过实际运用或计 算， 去除一些特定的频点等等， 以避免啸叫等等。 但这些方法都使声音严重失 真， 无法达到良好的音质要求。
[0004] 因此， 如何在不改变甚至提升音质的条件下， 使麦克风和音箱合二为一， 做到 便携小巧， 又具有直接的卡拉 OK效果， 让人们可以随吋随地享受歌唱， 享受音 乐带来的乐趣， 成为了许多人的梦想。

本发明的实施方式
[0020] 为了对本发明的技术特征、 目的和效果有更加清楚的理解， 现对照附图详细说 明本发明的具体实施方式。
[0021] 如图 1所示， 为本发明一种麦克风音箱一体设备的分解示意图， 包括麦克风和 音箱， 音箱包括容纳有扬声器 500的音腔 400， 特别地， 该麦克风音箱一体设备 包括一软性材料连接件 100， 该软性材料连接件 100呈如图所示的顶部封闭、 底 部幵口的圆筒状， 直径从上到下依次增大， 其固定连接在麦克风的底部和音腔 的顶部之间， 并用于抵制音箱产生的声音振动通过固体结构件传导到麦克风上 。 该麦克风音箱一体设备包括塑胶件 200和 PCB板 300， 塑胶件 200主要是起固定 作用的， 其顶部和底部均具有至少一个凸起， 如图所示， 以顶部具有一个凸起 2 01、 底部具有两个凸起 201和 202为例， 顶部凸起 201穿透软性材料连接件的顶部 (即与麦克风连接的一端） 以螺纹或螺钉的方式将软性材料连接件 100的顶部固 定在麦克风的底部， 可以理解的是， 软性材料连接件 100的顶部幵设有若干个孔 以便塑胶件 201上的凸起穿透至麦克风的底部。 [0022] 上述 PCB板 300也是通过该塑胶件 200固定连接， 其与音腔的顶部之间留有一定 的空隙， 具体地， 该 PCB板是通过该塑胶件 200底部的凸起以螺纹或螺钉的方式 将 PCB板 300固定在塑胶件 200的底部。 进一步地， PCB板 300上在本实施例中设 有第一接口 301和第二接口 302， 当然可以理解的是， 接口的个数是并不受限制 的， 其中： 第一接口 301为充电 /音频输入 /音频输出接口， 第二接口 302为音频输 出接口。 同吋软性材料连接件 100的侧臂上需幵设两个幵口 （图中未标出） ， 分 为第一幵口和第二幵口， 而第一接口 301和第二接口 302分别对应卡在第一幵口 和第二幵口中。 这样就避免了以前将这两个接口卡在麦克风底部的幵口上， 使 得外形更加美观。
[0023] 上述软性材料连接件 100可优选为硅胶， 因硅胶硬度较低， 能有效起到缓振的 作用， 可以理解的是， 也可选用其他软性材料， 如橡胶或者 TPU， 也可以选用软 塑胶等， 硬度大约在 80度或以下， 只要硬度较低能够有效缓振即可， 在此不作 限制。
[0024] 上述软性材料连接件 100的底部可以优选为通过螺纹或螺钉连接在音腔 400的顶 部， 也可直接通过包胶、 采用胶水等方式粘接在音腔 200顶部， 其连接方式在此 并不作限制， 只要能将软性材料连接件固定连接在音腔顶部即可， 当然， 这里 软性材料连接件与音腔顶部的连接是指边缘部分的连接， PCB板的底部与音腔的 顶部之间是需留有一定空隙的， 两者之间距优选为 4mm-5mm以上， 避免挨的太 近而造成缓振效果不好。
[0025] 上述音箱还包括硅胶圈 600、 塑胶圈 700及喇叭网 800， 其中： 硅胶圈 600、 塑胶 圈 700及喇叭网 800依次固定连接在扬声器 500底部， 扬声器 500的底部与音腔 200 的底部平齐， 最后麦克风和音箱一体设备的整体示意图如图 2所示。 其中： 塑胶 圈 700及硅胶圈 600可以通过螺纹或螺钉扣压在扬声器 500的底部， 使得音腔 200 密封， 而喇叭网 800则可以阻挡外界灰尘， 使扬声器 500发出的声音能够透出。 此外， 硅胶圈 600也是采用硬度较低的硅胶这一软性材料， 当然也可以采用其它 软性材料如橡胶、 TPU或软塑胶等， 从而使得该部分跟固体结构件如桌面或地面 等接触吋， 也能减缓音腔所发出的声音振动。
[0026] 因此通过将一软性材料连接件 100固定连接在麦克风的底部和音腔 400的顶部之 间， 同吋 PCB板 300的底部与音腔 200的顶部之间留有一定空隙， 因软性材料连接 件 300可以有效地减缓声音的振动且 PCB板 300与音腔 400不接触， 两者之间留有 空隙从而避免了音箱产生的声音振动传递到上边， 当人高声歌唱吋， 因 PCB板 30 0的底部与音腔 400的顶部之间留有一定空隙， 且音腔 400的顶部通过软性材料连 接件固定连接在麦克风的底部， 这样能有效地打破音箱传递到麦克风上的振动 ， 因此音箱产生的声音振动不再能通过固体结构件传导到麦克风咪头上， 从而 能非常有效地抑制啸叫的产生。
[0027] 优选地， 麦克风内部的电路板上还设有蓝牙模块， 用于与蓝牙通信设备如手机 等进行无线蓝牙通信连接， 该麦克风和音箱一体设备内部电路的原理框图如图 3 所示。 当从麦克风拾音咪头处输入声音吋， 声音进入电容麦克风， 先经过麦克 风声音混响处理， 然后分为三路， 一路输出至耳机功率放大单元， 一路输出至 喇叭功率放大单元， 还有一路输出至输出录音信号处理单元， 之后在喇叭幵 /关 控制使得喇叭处于幵启状态吋， 麦克风信号再通过喇叭功率放大后输出至喇叭 。 当使用该麦克风音箱一体设备的蓝牙功能吋， 麦克风幵启蓝牙模块 （包括图 3 中的蓝牙天线及蓝牙模组） ， 与手机等移动通信设备建立无线蓝牙通信连接后 ， 其手机中播放的声音经蓝牙模块中的蓝牙模组进入左右声道混合， 之后在喇 叭幵 /关控制使得喇叭处于幵启的状态下与人声一起通过喇叭功率放大后输出至 喇叭； 当不使用蓝牙连接外部设备吋， 也可以通过有线的方式从 MICRO USB接 口处输入外部音乐， 输入到喇叭功率放大后， 与人声一起输出至喇叭。
[0028] 此外， 上述描述的卡在软性材料连接件侧壁上的第一幵口处的第一接口 （充电 /音频输入 /音频输出接口， 即图 3所示的 MICRO USB接口） ， 通过该接口可以实 现对麦克风电池和蓝牙模块等各个需供电的模块进行供电， 同吋还可以连接外 部设备如手机等来播放音乐。
[0029] 综上所述， 实施本发明一种麦克风音箱一体设备， 通过塑胶件将软性材料连接 件的顶部固定连接在麦克风的底部， 软性材料连接件的底部固定在音腔的顶部 ， 同吋一样通过塑胶件固定连接的 PCB板的底部与音腔的顶部之间留有一定空隙 ， 当人高声歌唱吋， 因软性连接件能有效地打破音箱传递到麦克风上的振动， 使得音箱产生的声音振动无法再通过固体结构件传导到麦克风上来， 最后无法 正常传递到麦克风咪头处， 从而从根本上消除反馈自激机制的产生， 非常有效 地抑制了啸叫的产生。
[0030] 同吋通过该产品人们可以随吋随地的卡拉 OK， 不受场所和众多设备的限制， 让用户无论身处室内或室外， 正在旅途或是在山颠， 都能随吋高歌一曲， 和朋 友同欢， 此外， 手机现是人们随身携带的必不可少的物品， 通过幵启该麦克风 音箱一体设备的蓝牙功能， 便可与手机建立无线蓝牙连接， 用手机中播放的音 乐伴奏， 真正实现了卡拉 ΟΚ的效果。
[0031] 上面结合附图对本发明的实施例进行了描述， 但是本发明并不局限于上述的具 体实施方式， 上述的具体实施方式仅仅是示意性的， 而不是限制性的， 本领域 的普通技术人员在本发明的启示下， 在不脱离本发明宗旨和权利要求所保护的 范围情况下， 还可做出很多形式， 这些均属于本发明的保护之内。
