Embodiment 1

[0046] The invention discloses a bone conduction sound transmission device, which is a small and lightweight composite material bone conduction speaker. The device is composed of a packaged object 1 and a packaged object 2. The implementation of the configuration relationship includes but is not limited to the inclusion structure, the laminated structure and other composite structures formed on this basis. The configuration of the inclusion structure is described as an example below. relation.

[0047] As shown in Figure 1(a), it is a typical small and lightweight bone conduction speaker, which is composed of a wrap 1, a wrap 2 and a number of wires 3, wherein the wrap is completely surrounded by the wrap to present a contained structure, The wire 3 is electrically connected to the object to be wrapped 1 . Its adult body is presented as a cuboid connecting a group of two or more wires, the bone conduction sound transmission device formed by the containing structure can be des...

Embodiment 2

[0050] In order to show its structure more clearly, this embodiment discloses a bone conduction sound transmission device. The following describes a special example of the configuration relationship of the three types of wrappings composed of two or more materials by taking the longitudinal section of the rectangular parallelepiped as the main body.

[0051] attached figure 2 Shown is the first special case of the cuboid formed by the wrapping and the wrapping body, wherein the wrapping body b is an elongated thin piezoelectric ceramic containing two or more electrodes, and the wrapping body consists of the inner wrapping c and the inhabitants. The outer wrapping a outside it is laminated. The material used to form the inner wrap can be made of silicone, rubber and other soft substances. The outer wrap can be designed to completely or not completely wrap the inner wrap, leaving one or more sound-guiding surfaces d for direct or indirect contact with the periphery of the human...

Abstract

The invention discloses a bone conduction sound transmission technology, which can be used to manufacture a miniaturized and lightweight bone conduction sound transmission device. This kind of device can achieve good bone conduction sound effect when worn in a specific area around the human ear. At the same time, all components of the device are fully connected, and there is no artificial design or air cavity formed by structural gaps. The size of the device can be reduced and the sound leakage of the device can be effectively suppressed. Compared with the existing bone conduction speakers, the bone conduction sound transmission technology and the resulting bone conduction sound transmission device are especially suitable for wearing behind the ear due to their small size, light weight and easy to wear, and have good concealment Effect. At the same time, it is not necessary to form a continuous tight connection between the device and the user's skin, including long-term wear on the skin surface, causing vertical extrusion and discomfort, and the use of adhesion, magnetic attraction, hanging and clamping the outer ear, etc., is beneficial Long-term wear.

Description

technical field [0001] The invention relates to the technical field of bone conduction sound transmission, in particular to an external ear bone conduction sound transmission device that is miniaturized, lightweight, easy to install and hidden to wear. Background technique [0002] Bone conduction sound transmission technology is a technology in which the bone conduction speaker is placed in direct contact with the periphery of the human ear or through a medium device on the periphery of the human ear, which is conducive to receiving bone conduction. Since the sound transmission device is mainly transmitted through the pinna or other medium channels without blocking the outer ear and middle ear vestibule, it will be beneficial to the natural rank coupling with other auditory information in the user's surrounding environment without causing auditory masking or blocking. [0003] The sound waves generated by bone conduction speakers are generated by bone conduction transducers...
