MP3播放器等等。 用户在使用耳机时， 既可以独自享受音乐带来的乐趣， 又不 会影响到他人。
耳机中的耳壳腔体（即， 音腔）对耳机声音的表现起着非常重要的作用， 现有的耳机为了高质量地表现出低音， 尤其是重低音的震撼力度， 通常采用双 音腔的设计， 如图 1所示， 目前的耳机一般由前盖 80、 喇叭面壳 81、 喇叭 82 构成前腔 91 , 由后盖 83、 喇叭面壳 81、 喇叭 82构成后腔 92, 喇叭 82和后腔 92之间的部位为排气孔 90, 该排气孔 90的作用之一是排气。 当前， 图 1只是 最筒单的情况， 在实际应用中， 不同的耳机会有不同的设计， 但原理一致， 且 基本都是由喇叭面壳和喇叭将耳机的前后腔体隔开。
但是， 本发明人在实施本发明的过程中发现， 目前采用的这种双音腔设计 的耳机在实际使用过程中， 由于喇叭向外不断的播出声音， 会使耳机的前腔中 积留较多的气体， 当前腔中积留的气体过多时， 就会直接影响耳机播出的声音 的音质， 主要表现在于声音模糊、 不清晰。 发明内容
本发明实施例所要解决的技术问题在于， 提供一种耳壳腔体及对应的耳机， 可以及时的释放积留在耳机前腔的多余气体， 且能够很好的控制气体释放过程， 不至于产生新的杂音， 从而保证耳机播出的声音清晰， 提高用户的使用体验。
为了解决上述技术问题， 本发明实施例提供了一种耳壳腔体， 包括： 喇叭 面壳 （1 )、 喇叭腔体（2 )、 喇叭（3 )和后壳 （4 );
所述喇叭腔体（2 ) 为环状的迷宫型结构， 固定在所述喇叭面壳 （1 )上； 所述喇叭面壳（ 1 )上设有一用于供气体从中通过，并进入所述喇叭腔体（ 2 ) 的第一气口 （11 ); 所述喇叭腔体（2 ) 与所述第一气口 （11 )相对应的位置设 有用于供气体进入喇叭腔体（2) 的第二气口 （21);

其中， 所述喇叭（2) 的设置于由喇叭面壳 （1 )和喇叭腔体（2)所围成的 桶状空间内。
其中， 所述喇叭面壳 （1 ) 的中央设有一供喇叭（3)所发出的声音向外传 递的第一通孔（12), 所述通过的形状与所述喇叭（3) 的发音面的形状一致。
其中， 所述喇叭腔体（2) 包括基板 (22)和腔体（23);
所述基板 (22) 的中央均匀的设有供喇八 (3)所发出的声音向外传递的第 二通孔（ 23 ), 所述基板（ 22 )上设置第二通孔（ 23 )的区域与所述喇叭面壳（ 1 ) 上第一通孔（12)所在的区域对应；
所述基板 (22) 的外沿设置环状的迷宫型腔体（23); 所述基板 (22) 中央 设置有第二通孔（23) 的区域与所述迷宫型腔体（23) 的侧壁围成一用于容纳 喇八 (3) 的桶状空间。
其中， 所述喇叭面壳 （1 ) 的中央均匀的设有供喇叭（3)所发出的声音向 外传递的第一通孔（24), 所述喇叭面壳 （1)上设置第一通孔（24) 的区域与 所述喇八 (3) 的发音面的形状一致。
其中， 由所述喇叭腔体（2)所围成的区域与所述喇叭面壳 （1 )上设置第 一通孔（24) 的区域一致， 且喇叭腔体（2) 的侧壁与所述喇叭面壳 （1 )上设 置第一通孔（24) 的区域围成一用于容纳喇叭（3) 的桶状空间。
相应的， 本发明实施例还提供一种耳机， 该耳机包括如前所述的耳壳腔体。 其中， 通过第一气口 （11)、 第二气口 （21 )进入喇叭腔体（2) 的气体是 所述耳机的前腔中积留的气体。
本发明实施例所提供的耳壳腔体及对应的耳机， 可以及时的释放积留在耳 机前腔的多余气体， 且能够 ^艮好的控制气体释放过程， 不至于产生新的杂音， 从而保证耳机播出的声音清晰， 提高用户的使用体验。 附图说明 例或现有技术描述中所需要使用的附图作筒单地介绍， 显而易见地， 下面描述 中的附图仅仅是本发明的一些实施例， 对于本领域普通技术人员来讲， 在不付 出创造性劳动的前提下， 还可以根据这些附图获得其他的附图。
图 1是现有的耳机结构示意图；
图 2为本发明提供的耳壳腔体第一实施例结构示意图；
图 3为本发明提供的耳壳腔体第二实施例结构示意图；
图 4为本发明提供的耳壳腔体中喇八腔体的结构示意图。 具体实施方式
本发明实施例所提供的耳壳腔体及对应的耳机， 可以及时的释放积留在耳 机前腔的多余气体， 且能够 ^艮好的控制气体释放过程， 不至于产生新的杂音， 从而保证耳机播出的声音清晰， 提高用户的使用体验。
下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
参见图 2, 为本发明提供的耳壳腔体第一实施例结构示意图， 如图 2所示， 该耳壳腔体包括： 喇叭面壳 1、 喇叭腔体 2、 喇叭 3和后壳 4。
所述喇叭腔体 2为环状的迷宫型结构， 固定在所述喇叭面壳 1上。
所述喇叭面壳 1上设有一用于供气体从中通过， 并进入所述喇叭腔体 2的 第一气口 11;所述喇叭腔体 2与所述第一气口 11相对应的位置设有用于供气体 进入喇叭腔体 2的第二气口 21。
所述后壳 4为可容纳所述喇叭腔体 2、 喇叭 3的碗状结构。
其工作原理为， 当耳机前腔中有多余的气体积留时， 多余的气体在压力作 用下通过第一气口 11、 第二气口 21进入喇叭腔体 2, 最后从耳机内部排出， 从 而使前腔中积留的多余气体得到释放， 避免其影响耳机的音质。 在本发明中， 将喇八腔体设计为迷宫型， 可以使排出气体的过程容易控制， 避免其产生杂音， 影响耳机的播放效果。
参见图图 3 , 为本发明提供的耳壳腔体第二实施例结构示意图。在本实施例 中， 将更为详细的描述该耳壳腔体的具体结构和各部件的功能。 如图所示， 该 耳壳腔体包括： 喇叭面壳 1、 喇叭腔体 2、 喇叭 3和后壳 4。 喇叭腔体 2可以固 定在喇叭面壳 1上， 喇叭 3则容纳于喇叭面壳 1和喇叭腔体 2所围成的桶状空 间内， 后壳 4为碗状结构， 其内部可容纳喇叭腔体 2和喇叭 3 , 后壳 4的边缘可 与喇八面壳 1扣合。
更为具体的， 所述喇叭面壳 1上设有第一气口 11 , 其用于供气体从中通过， 并进入所述喇叭腔体 2。 对应的， 所述喇叭腔体 2与所述第一气口 11相对应的 位置设有第二气口 21 , 用于供通过第一气口 11的气体由此进入喇叭腔体 2。 所 述后壳 4上设有第三气口 41 , 用于供通过喇叭腔体 2的气体由此排出耳壳腔体 外。
其工作原理为， 喇叭 3处于工作状态时， 会使耳机前腔中不断的积留气体， 当积留的气体达到一定数量后， 就会影响耳机的音质， 使耳机播出的声音模糊 不清。 当耳机中采用本发明提供的耳壳腔体后， 当耳机前腔有多余的气体积留 时， 多余的气体在压力作用下通过第一气口 11、 第二气口 21进入喇叭腔体 2, 最后从后壳 4上设有第三气口 41排出， 从而使耳机前腔中积留的多余气体得到 释放， 从而减少一些无用的杂音， 避免其影响耳机的音质。
进一步的， 本发明的关键在于设计了环状迷宫型结构的喇八腔体 2, 而喇八 腔体 2具有结构可以是多种多样的， 本实施例中以其中两种为例。
第一种如图 4所示：
喇叭面壳 1的中央设有一供喇叭 3所发出的声音向外传递的第一通孔 12, 所述第一通孔 12的形状与所述喇叭 3的发音面的形状一致。 喇叭面壳 1与喇叭 腔体 2的迷宫型音腔对应的位置设有第一气口 11 ,第一气口 11的大小可以调节 进入喇八腔体 2的气体流量， 从而达到某种音质要求。
所述喇叭腔体 2包括基板 22和腔体 23;
所述基板 22的中央均匀的设有若干供喇八 3所发出的声音向外传递的第二 通孔 221 , 所述基板 22上设置第二通孔 221的区域与所述喇叭面壳 1上第一通 孔 12所在的区域对应； 所述基板 22的外沿设置环状的迷宫型腔体 23; 所述基 板 22中央设置有第二通孔 221的区域与所述迷宫型腔体 23的侧壁围成一用于 容纳喇八 3的桶状空间。
第二种是： 喇八面壳的中央均匀的设有若干供喇八所发出的声音向外传递 的第一通孔， 所述喇叭面壳上设置第一通孔的区域与所述喇叭的发音面的形状 一致。 喇叭面壳与喇叭腔体的迷宫型音腔对应的位置设有第一气口 1 , 第一气口 的大小可以调节进入喇叭腔体的气体流量， 从而达到某种音质要求。
由所述喇叭腔体所围成的区域与所述喇叭面壳上设置第一通孔的区域一 致， 且喇叭腔体的侧壁与所述喇叭面壳上设置第一通孔的区域围成一用于容纳 喇八的桶状空间。
本发明提供的耳壳腔体可以提供不同的声音效果通过耳机前腔到达耳朵。 其具体不同的音质效果主要由控制不同的气流从喇叭面壳 1的第一气口 n进入 迷宫型喇叭腔体 2, 最后通过后壳 4上的第三气口 41释放产生。
不同大小的喇叭腔体或迷宫会影响通过喇叭面壳进入到喇叭腔体， 最后从 后壳第三气口 41释放的气流量。 一旦确定喇叭腔体的大小或迷宫的大小， 当耳 机工作时， 气流从外部通过喇叭面壳上的第一气口进入迷宫型的喇叭腔体， 从 而增加喇八腔体内的气流压力， 增加的气流压力主要由外部的气流在喇八迷宫 型腔体流动而产生， 然后在喇叭腔体内形成更高的气流， 并通过后壳的第三气 口 41释放。 这样的持续过程会逐步减少耳机前腔内的气流体积。 此外， 当迷宫 型的喇八腔体比较长时， 在释放气体的过程中， 会在迷宫型腔体内产生沖力， 帮助气体排出， 相反， 如果腔体设计得太小， 则会阻碍气流在腔体内的流动。
综上所述本发明提供的耳壳腔体将喇叭腔体设计为迷宫型， 可以及时的释 放积留在耳机前腔的多余气体， 且能够很好的控制气体释放过程， 不至于产生 新的杂音， 从而保证耳机播出的声音清晰， 提高用户的使用体验。
需要说明的是， 本发明各实施例中提供的耳壳腔体可适用于各种类型的耳 机。
值得注意的是， 本发明描述的是耳壳腔体及对应的耳机的一种产品形式， 其它满足本发明所述结构的产品， 即使材质、 器件名称、 外观、 器件摆放顺序 等不影响产品特性的因素不相同， 仍然属于本发明保护的范围。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干筒单推演或替 换， 都应当视为属于本发明的保护范围。
