有鉴于此, 本发明实施例提供了一种通讯设备, 所述通讯设备包括: 通讯 设备壳体(1)、 电路板(2)、 耳机孔(3)、 耳机座(4)、 第一麦克(5)、 第一 通孔(7)、 第二通孔(8);
其中,
所述电路板 ( 2 )、 所述耳机孔 ( 3 )、 所述耳机座 ( 4 )、 所述第一麦克 ( 5 )、 所述第一通孔(7)、 所述第二通孔(8)位于所述通讯设备壳体(1 ) 内;
所述耳机座(4)位于所述耳机孔(3) 的内壁表面;

所述第一通孔 ( 7 )位于所述耳机座 ( 4 )、 所述电路板 ( 2 )和所述第一麦 克(5) 的交叠区域, 且贯穿所述电路板 (2);
所述第二通孔(8)位于所述耳机座(4)上, 且贯穿所述耳机座(4); 所述第一通孔(7)—端与所述第一麦克(5)相连通, 另一端与所述第二 通孔(8)相连通 由上可知, 本发明实施例所提供的通讯设备, 除包括: 电路板、 耳机孔、 耳机座和第一麦克外, 还包括: 位于所述电路板上的第一通孔, 所述第一通孔 位于所述耳机座、 电路板和第一麦克的交叠区域, 且贯穿所述电路板; 位于所 述耳机座上的第二通孔, 所述第二通孔与所述第一通孔、 外界空气相连通。 因 此,在本发明实施例所提供的通讯设备中, 所述耳机座和第一麦克可以共用一 个通孔 (即耳机孔 )与外界空气相通, 从而使得所述通讯设备的耳机口同时作 为第一麦克的麦克口,而无需再在壳体上额外设置与第一麦克相对应的麦克开 孔, 减少所述通讯设备外壳上麦克开孔的数量, 降低了所述通讯设备的成本, 还提高了所述通讯设备的整体美观性。
为使本发明的上述目的、特征和优点能够更为明显易懂, 下面结合附图对 本发明的具体实施方式做详细的说明。 本发明所提供的通讯设备可以为手机, 也可以为平板电脑等其他通讯设备, 本发明对此并不做限定, 只要所述通讯设 备包括耳机装置和麦克装置即可。 下面以所述通讯设备为手机为例,对本发明 实施例所提供的通讯设备进行详细说明。
在以下描述中阐述了具体细节以便于充分理解本发明。但是本发明能够以 多种不同于在此描述的其它方式来实施,本领域技术人员可以在不违背本发明 内涵的情况下做类似推广。 因此本发明不受下面公开的具体实施的限制。 如图 2所示, 本发明实施例所提供的通讯设备包括: 通讯设备壳体 1、 电 路板 2、 耳机孔 3、 耳机座 4、 第一麦克 5、 第一通孔 7、 第二通孔 8; 其中, 所述电路板 2、 所述耳机孔 3、 所述耳机座 4、 所述第一麦克 5、 所述第一通孔 7、 所述第二通孔 8位于所述通讯设备壳体 1内; 所述耳机座 4位于所述耳机 孔 3的内壁表面; 所述电路板 2一侧与所述耳机座 4的外壁表面电连接, 另一 侧与所述第一麦克 5电连接; 所述第一通孔 7位于所述耳机座 4、 所述电路板 2和所述第一麦克 5的交叠区域, 且贯穿所述电路板 2; 所述第二通孔 8位于 所述耳机座 4上, 且贯穿所述耳机座 4; 所述第一通孔 7—端与所述第一麦克 5相连通, 另一端与所述第二通孔 8相连通, 即所述第一麦克 5上的开口 51 通过所述第一通孔 7和第二通孔 8与外界空气相连通。
在本发明的一个实施例中, 为了缩短所述第一通孔 7 沿所述第一麦克 5 至所述耳机座 4方向上的长度,所述第一通孔 7在所述第一麦克 5朝向所述耳 机座 4的方向上贯穿所述电路板 2 , 优选的, 所述第一通孔 7垂直贯穿所述电 路板 2 , 即所述第一通孔 7的路径为平行于所述第一麦克 5朝向所述耳机座 4 的方向的直线, 以保证所述第一通孔 7的路径最短。但在本发明的其他实施例 中, 所述第一通孔 7的路径也可以为斜线或曲线, 本发明对此并不做限定, 只 要保证所述第一通孔 7、 第二通孔 8和外界相连通即可。
在本发明的另一个实施例中, 所述第二通孔 8与所述耳机座 4的端口 41 之间的距离大于所述第二通孔 8与所述耳机座 4底部(即与所述耳机座 1端口 41相对的一侧)之间的距离, 以缩短所述第二通孔 8距离耳机口的距离, 提 高所述第一麦克 5采集到的语音信号强度或环境噪声信号的强度。需要说明的 是, 理论上而言, 所述第二通孔 8在耳机座 4上的位置越接近所述耳机座 4 的端口 41 (即所述通讯设备外壳上的耳机口 ) 的位置, 所述第一麦克 5采集 到的语音信号或环境噪声信号的强度越大,但是本发明对此并不做限定,视具 体情况而定,只要保证所述第一麦克 5和耳机座 4共用所述通讯设备上的一个 开孔(即耳机口), 即可减少所述通讯设备外壳上开孔的数量, 降低所述通讯 设备的工艺难度和成本。
在本发明的又一个实施例中, 所述第二通孔 8的孔径大于所述第一通孔 7 的孔径,从而充分利用所述第一通孔 7的空腔,提高所述第一麦克 5采集到的 语音信号或环境噪声信号的强度。但在本发明的其他实施例中, 所述第二通孔 8 的孔径也可以与所述第一通孔 7 的孔径相等或略小于所述第一通孔 7 的孔 径, 本发明对此并不做限定。
需要说明的是, 由于本发明实施例所提供的通讯设备中, 所述耳机座 4 上设置有第二通孔 8 , 即采用非封闭式设计, 从而使得所述通讯设备在日常使 用过程中, 外界环境中的灰尘容易通过所述第二通孔 8 进入所述通讯设备内 部, 在所述通讯设备内部形成脏污。
因此, 在本发明的一个实施例中, 所述通讯设备还包括: 防尘装置 6 , 所 述防尘装置 6位于所述第一通孔 7和第二通孔 8之间,以隔绝外界环境中灰尘, 避免外界环境中的灰尘进入所述通讯终端内部。优选的, 所述防尘装置 6为防 尘网,从而既不影响所述第一麦克 5采集语音信号或环境噪声信号的强度,还 可以隔绝外界环境中灰尘, 避免外界环境中的灰尘进入所述通讯终端内部。
需要说明的是,在本发明的一个实施例中, 所述通讯设备只包括第一麦克 5 , 如图 3所示; 在本发明的另一个实施例中, 所述通讯设备还包括: 第二麦 克(图中未示出)和第二麦克孔 9 , 其中, 所述第二麦克位于所述通讯设备壳 体 1内,且与所述电路板 2电连接, 所述第二麦克孔 9位于所述通讯设备壳体 1上, 且与所述第二麦克相连通, 从而使得本发明实施例所提供的通讯设备可 以利用双麦降噪的原理,让通话的接收方只听到通话语音,而听不到环境噪声 , 提高通话质量。
在本发明的又一个实施例中,所述通讯装置还可以为三麦克装置或 M麦克 装置, 在该实施例中, 所述通讯装置还包括: 第 N麦克和第 N麦克孔, 其中, 所述第 N麦克位于所述通讯设备壳体 1内,且与所述电路板 2电连接, 所述第 N麦克孔位于所述通讯设备壳体 1上, 且与所述第 N麦克相连通, 以进一步提 高通话质量; 其中, N依次为大于 2 , 且小于 M的正整数, M为大于 4的正整 数。
需要说明的是, 当本发明实施例所提供的通讯装置为多麦克装置(即非单 麦克)时, 所述第一麦克 5可以主麦克, 位于靠近声源(即用户的嘴巴)的一 端, 用于同时接收通话的语音信号和环境噪声信号, 也可以为次麦克, 位于远 离声源的一端, 主要收集环境噪声信号, 本发明对此并不做限定, 视耳机座 4 的位置而定, 即所述耳机座 4位于靠近声源(即用户的嘴巴)的一端时, 所述 第一麦克 5为主麦克, 所述耳机座 4位于远离声源的一端时, 所述第一麦克 5 为次麦克。
综上所述, 本发明实施例所提供的通讯设备, 除包括: 电路板 2、 耳机孔 3、 耳机座 4和第一麦克 5外, 还包括: 位于所述电路板 2上, 与所述第一麦 克 5相连通的第一通孔 7 , 所述第一通孔 7位于所述耳机座 4、 电路板 2和第 一麦克 5的交叠区域, 且贯穿所述电路板 2; 位于所述耳机座 4上的第二通孔 8 , 所述第二通孔 8与所述第一通孔 7、 外界空气相连通。 因此, 在本发明实 施例所提供的通讯设备中, 所述耳机座 4和第一麦克 5可以共用一个通孔 (即 耳机孔 3 )与外界空气相通, 从而使得所述通讯设备的耳机口同时作为第一麦 克 5的麦克口, 而无需再在壳体上额外设置与第一麦克相对应的麦克开孔, 减 少所述通讯设备外壳上麦克开孔的数量,降低所述通讯设备的工艺难度和制作 成本还提高了所述通讯设备的整体美观性。
本说明书中各个部分采用递进的方式描述,每个部分重点说明的都是与其 他部分的不同之处, 各个部分之间相同相似部分互相参见即可。
需要说明的是,在本文中,诸如第一和第二等之类的关系术语仅仅用来将 一个实体与另一个实体区分开来,而不一定要求或者暗示这些实体之间存在任 何这种实际的关系或者顺序。 而且, 术语 "包括"、 "包含" 或者其任何其他变 体意在涵盖非排他性的包含,从而使得包括一系列要素的物品或者设备不仅包 括那些要素, 而且还包括没有明确列出的其他要素, 或者是还包括为这种物品 或者设备所固有的要素。 在没有更多限制的情况下, 由语句 "包括一个 ... ... " 限定的要素,并不排除在包括所述要素的物品或者设备中还存在另外的相同要 素。
对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本 发明。 对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见 的, 本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下, 在 其它实施例中实现。 因此, 本发明将不会被限制于本文所示的实施例, 而是要 符合与本文所公开的原理和新颖特点相一致的最宽的范围。
