Embodiment 1

[0047] The invention discloses a bone conduction sound transmission device, which is a small and lightweight composite material bone conduction loudspeaker. 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 a containment structure, a laminated structure and other composite structures formed on this basis. The following uses the containment structure as an example to illustrate its configuration relation.

[0048] As shown in Figure 1(a), a typical small and lightweight bone conduction speaker is composed of a wrapped object 1, a wrapped object 2, and several wires 3, wherein the wrapped object is completely surrounded by the wrapped object and presents a containment structure. The wire 3 is electrically connected to the wrapped object 1 . Its body appears as a cuboid connected with a group of two or more wires. The bone conduction sound transmission device formed by the co...

Embodiment 2

[0051] 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 three types of wrappings made of two or more materials, taking the longitudinal section view of the cuboid as the main body.

[0052] attached figure 2 Shown is the first special case of the cuboid formed by the wrapper and the wrapper, in which the wrapper b is a strip-shaped thin piezoelectric ceramic containing two or more electrodes, and the wrapper is composed of the inner wrapper c and the The outer wrapping a is laminated. The material used to form the inner wrapping can be formed of silica gel, rubber and other soft substances. The outer wrapping can be designed to fully or incompletely wrap the inner wrapping, leaving one or more sound-guiding surfaces d for direct or indirect contact with the outer periphery of the human ear. It is worth noting that, figure 2 The bon...

Abstract

The invention discloses a bone conduction sound transmission technology, which can be used for manufacturing a miniaturized and light-weight bone conduction sound transmission device. The device can achieve a good bone conduction sound transmission effect when being worn in a specific area around the human ears, and meanwhile, all components of the device are fully and tightly connected to each other, an air cavity formed by the artificial design or structural gaps does not exist, and thus the size of the device can be reduced, and the sound leakage of the device can be effectively inhibited.Compared with an existing bone conduction loudspeaker, the bone conduction sound transmission device formed by the bone conduction sound transmission technology thereby is especially suitable for being worn behind the ears due to the characteristics of small size, light weight and easy wearing, and the device has a good concealment effect. At the same time, the device does not need to form a continuous tight connection with the skin of a user, wherein the continuous tight connection includes the operation of long-termly wearing the device on the skin surface to cause the squeezing in the vertical direction and form discomfort; and the modes of bonding, magnetic attraction, hanging, clamping the external ears and other methods are adopted, and thus the device is beneficial to long-term wearing.

Description

technical field [0001] The invention relates to the technical field of bone conduction sound transmission, in particular to a bone conduction sound conduction device for the outer ear that is miniaturized, light in weight, easy to install and concealed to wear. Background technique [0002] Bone conduction sound transmission technology is a technology in which bone conduction speakers are placed in direct contact with the outer periphery of the human ear or through a medium device on the part of the outer periphery of the human ear that is conducive to receiving bone conduction. Sound waves enter the middle ear through the outer periphery of the human ear and are finally sensed by the auditory nerve. Since the sound transmission device is mainly transmitted through the auricle or other media channels without blocking the outer ear and the vestibule of the middle ear, it will be conducive to the natural orderly coupling with other auditory information in the user's surrounding...
