Embodiment 1

[0069] A gesture-recognizable bluetooth headset, such as figure 1 As shown, it includes the speaker 2 packaged on the top of the earphone shell through the top cover 1 and the charging interface 6 installed at the bottom of the earphone shell through the bottom cover 7; there are also:

[0070] The sensing unit 5 is packaged with an acceleration sensor and an angular velocity sensor through a gyroscope, which are respectively used to collect acceleration and angular velocity data when the earphone moves with the head; Multiple photosensors, and photosensitive holes are set at the earphone shell where each photosensor is set; the photosensor collects the distance between the earphone and the ear through the photosensitive hole and judges whether the earphone is in the ear, causing an interruption and sending a signal to the control unit;

[0071] The control unit 4 includes a control single-chip microcomputer, which is connected with the sensing unit 5 through an FPC soft boar...

Embodiment 2

[0081] On the basis of embodiment 1, the preparation method of the bluetooth earphone of recognizable gesture, comprises the following steps:

[0082] A1. Open the top cover and bottom cover of the earphone;

[0083] A2. If Image 6 As shown, slowly insert the charging interface, sensor unit, control unit, Bluetooth module, storage unit, power supply unit, light sensor, and speaker from the upper opening of the earphone shell in sequence, so that the charging interface is fixed at the lower opening of the earphone shell, and adjust Angle, to ensure that each light sensor corresponds to the position of the photosensitive hole, and to ensure that the speaker is fixed at the upper opening of the earphone shell;

[0084] A3. Install the bottom cover and top cover.

[0085] Since this solution needs to use a square bluetooth master microcontroller QCC3020, its side length exceeds 5mm, and the side length of the circuit board of the sensing unit exceeds 6mm. Therefore, the "bottom...

Embodiment 3

[0088] On the basis of Embodiment 1, the control method of the bluetooth headset that can recognize the gesture, such as Figure 7 shown, including the following steps:

[0089] B1. Initialize the sensor, set the measurement range and precision of the acceleration sensor and the angular velocity sensor; and set the count threshold, trigger threshold and attitude number-command mapping table including the acceleration threshold and the angular velocity threshold on the control unit;

[0090] B2. When the earphone moves with the head, it detects a single gesture;

[0091] Among them, such as Figure 8 As shown, the steps to detect a single pose are as follows:

[0092] S1. When the earphone moves with the head, the acceleration sensor and the angular velocity sensor respectively collect the current acceleration raw data and angular velocity raw data of the earphone, express it through 16-bit two's complement data or quaternion data, and transmit it to the control unit;

[009...

Abstract

The invention relates to the technical field of electronic information, and discloses a Bluetooth earphone capable of recognizing a posture and a control method thereof. The Bluetooth earphone comprises a sensing unit comprising an acceleration sensor and an angular velocity sensor, a control unit connected with the sensing unit through an FPC soft board, and a storage unit connected to the control unit. The acceleration sensor and the angular velocity sensor collect acceleration and angular velocity data when the earphone moves along with the head. The control unit receives and processes theacceleration and angular velocity data, determines the movement direction of the earphone according to the processed data, counts when the data is greater than or equal to a counting threshold value,and determines the movement posture of the earphone when the counting number is greater than a triggering threshold value; when the earphone stops moving, determines a single posture; when the earphone continues to move, detects the next posture until the earphone stops moving, and fuses multiple single postures to obtain a complex posture; and determines a corresponding control instruction in theattitude number instruction mapping table according to the single attitude or the complex attitude, and sends the control instruction to the communication terminal.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a gesture-recognizable bluetooth earphone and its preparation and control methods. Background technique [0002] Compared with ordinary earphones, bluetooth earphones transmit audio and control signals between devices through wireless bluetooth, without using ordinary signal lines, which greatly increases portability. [0003] The neck of the existing bluetooth headset is provided with a button and a charging interface, which is installed from the bottom up to control the single-chip circuit board to ensure that the circuit board and the charging interface are aligned; When it is ≤4.5mm, it will not be possible to install a control microcontroller with a large package or a circuit board with many units. [0004] In addition, the existing bluetooth earphones all control the bluetooth earphones through buttons. This operation mode must be adjusted and controlled by ...
