Problems solved by technology

The current defect of this technology is that when the bone conduction environmental noise reduction technology is implemented, the microphone of the traditional sound pickup device with a bone vibration detection sensor will always be turned on, resulting in increased power consumption of the earphone, which is not conducive to the long-term use of the earphone.

Embodiment Construction

[0040] Such as figure 1 As shown, the built-in algorithm processing unit of the earphone of this embodiment, and the human body induction module, three-axis acceleration sensor and microphone module electrically connected to the algorithm processing unit respectively, wherein:

[0041] Algorithm processing unit: adopts conventional controller, mainly runs the drive and algorithm of each sensor;

[0042] Human body sensing module: including but not limited to one or more infrared / capacitive sensors, the core of which is to output signals of different intensities by detecting the contact degree between the infrared / capacitive sensors and the human body surface, so as to judge whether the earphone is worn in place, For prior art, do not go into details here;

[0043] Three-axis acceleration sensor: It is used to detect the vocal cord vibration caused by the muscles attached to the skull when the user speaks. In this paper, it mainly detects the direction perpendicular to the sur...

Abstract

The invention relates to a method for controlling a microphone switch by a three-axis acceleration sensor, electronic equipment and a computer readable storage medium. The method is used for reducingthe power consumption of an earphone, and comprises the following steps: step A, starting the three-axis acceleration sensor in the earphone to carry out X, Y and Z three-axis data acquisition on vocal cord vibration caused by skull attached muscles when a user speaks, and controlling the Z axis of the three-axis acceleration sensor to be perpendicular to the direction of ears of the user and parallel to the horizontal direction in the acquisition process; step B, cyclically detecting an energy accumulation value of Z-axis data in a period according to a set detection period, and triggering tostart the microphone to pick up sound when the energy accumulation value of the Z axis exceeds a set bone vibration switch threshold value; and step C, after the microphone is started, if the energyaccumulation value of the Z axis is not detected to exceed the bone vibration switch threshold after the set duration is continuously exceeded, turning off the microphone.

Description

technical field [0001] The invention relates to the field of earphone broadcasting, in particular to a method for controlling a microphone switch by a three-axis acceleration sensor, electronic equipment, and a computer-readable storage medium. Background technique [0002] The bone vibration detection sensor (that is, the three-axis acceleration sensor) refers to the sensor that detects the movement of the skull when speaking. It is different from the traditional microphone that picks up sound through air conduction. It is a relatively hot research direction in recent years, especially It is Huawei Freebuds3 and Apple's AirPods Pro that have been launched recently, which have driven the development of various bone conduction wearable product technologies in the market, among which bone conduction environmental noise reduction technology is relatively hot. [0003] Bone conduction environmental noise reduction technology refers to the use of bone vibration detection sensors ...
