[0054]为了更清楚地说明本申请实施例的技术方案，下面将对实施例描述中所需要使用的附图作简单的介绍。显而易见地，下面描述中的附图仅仅是本申请的一些示例或实施例，对于本领域的普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图将本申请应用于其它类似情景。除非从语言环境中显而易见或另做说明，图中相同标号代表相同结构或操作。应当理解的是，附图仅仅是为了说明和描述的目的，并不旨在限制本申请的范围。应当理解的是，附图并不是按比例绘制的。

[0055]需要理解的是，为了便于对本申请的描述，术语“中心”、“上表面”、“下表面”、“上”、“下”、“顶”、“底”、“内”、“外”、“轴向”、“径向”、“外周”、“外部”等指示的位置关系为基于附图所示的位置关系，而不是指示所指的装置、组件或单元必须具有特定的位置关系，不能理解为是对本申请的限制。

[0056]应当理解，本文使用的“系统”、“装置”、“单元”和 / 或“模组”是用于区分不同级别的不同组件、元件、部件、部分或装配的一种方法。然而，如果其他词语可实现相同的目的，则可通过其他表达来替换所述词语。

[0057]如本申请和权利要求书中所示，除非上下文明确提示例外情形，“一”、“一个”、“一种”和 / 或“该”等词并非特指单数，也可包括复数。一般说来，术语“包括”与“包含”仅提示包括已明确标识的步骤和元素，而这些步骤和元素不构成一个排它性的罗列，方法或者设备也可能包含其它的步骤或元素。

[0058]本申请中使用了流程图用来说明根据本申请的实施例的系统所执行的操作。应当理解的是，前面或后面操作不一定按照顺序来精确地执行。相反，可以按照倒序或同时处理各个步骤。同时，也可以将其他操作添加到这些过程中，或从这些过程移除某一步或数步操作。

[0059]本申请一些实施例提供的骨传导传声装置可以包括基体结构和叠层结构。在一些实施例中，基体结构可以为内部具有中空部分的规则或不规则的立体结构，例如，可以是中空的框架结构体，包括但不限于矩形框、圆形框、正多边形框等规则形状，以及任何不规则形状。叠层结构可以位于基体结构的中空部分或者至少部分悬空设置在基体结构中空部分的上方。在一些实施例中，叠层结构的至少部分结构与基体结构通过物理方式进行连接。这里的“连接”可以理解为在分别制备叠层结构和基体结构后，将叠层结构和基体结构通过焊接、铆接、卡接、螺栓等方式固定连接...

Abstract

The invention discloses a bone conduction sound transmission device. The bone conduction sound transmission device comprises a laminated structure formed by a vibration unit and an acoustic transduction unit; the base body structure is configured to bear the laminated structure, and at least one side of the laminated structure is connected with the base body structure in a physical mode; the base body structure generates vibration based on an external vibration signal, and the vibration unit deforms in response to the vibration of the base body structure; the acoustic transduction unit generates an electric signal based on the deformation of the vibration unit.

Description

technical field [0001] The present application relates to the technical field of sound transmission devices, in particular to a bone conduction sound transmission device. Background technique [0002] The microphone receives the external vibration signal, uses the acoustic transducer unit to convert the vibration signal into an electrical signal, and outputs the electrical signal after being processed by the back-end circuit. The air conduction microphone receives the air conduction sound signal, and the sound signal is transmitted through the air, that is, the air conduction microphone receives the air vibration signal. The bone conduction microphone receives bone conduction sound signals, and the sound signals are transmitted through human bones, that is, the bone conduction microphone receives bone vibration signals. Compared with air conduction microphones, bone conduction microphones have advantages in noise immunity. In a noisy environment, bone conduction microphones...
