Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, in t...

Abstract

The invention discloses a bone voiceprint sensor and electronic equipment. Wherein, the bone voiceprint sensor includes a microphone assembly and a vibration system, and a first airtight cavity is provided between the vibration system and the microphone assembly; the vibration system includes a casing that is arranged on the outside of the microphone assembly and encloses with the microphone assembly to form a sealed cavity, An elastic membrane arranged in the sealed cavity and separating the sealed cavity into a first closed cavity and a second closed cavity, a quality block arranged on the surface of the elastic membrane, and a first expansion of the surface of the elastic membrane provided with the mass block Arm, the first airtight cavity communicates with the microphone assembly through the sound hole on the outer surface of the microphone assembly; one end of the first extension arm is connected to the mass block, and the first extension arm is from the mass block to the edge of the elastic membrane and along the circumference of the elastic membrane set in a helical structure. The technical solution of the invention can prevent the elastic membrane from entering fatigue state or being damaged prematurely.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a bone voiceprint sensor and electronic equipment using the bone voiceprint sensor. Background technique [0002] The bone voiceprint sensor is a sensor that uses the vibration of the acoustic film to instigate air flow and detects flow signals. The bone voiceprint sensor usually includes a vibration system and a microphone component. The vibration system is used to sense external vibration information and generate a response vibration signal. The microphone component is used to convert the external response vibration signal into an electrical signal to express the vibration information. The existing vibration system includes an elastic membrane and a quality block arranged on the elastic membrane. However, due to the relatively large mass of the mass block, it also has a large impact on the elastic membrane during vibration, which may easily cause the elastic membrane to enter ...
