Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a communication method between an earphone and an earphone box according to a first embodiment of the present invention.
Embodiments of the present invention provide embodiments of methods of communication of headphones with a headphone case, it being noted that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order different from that shown or described herein. In the present embodiment, the earphone-to-earphone-box communication method is applied to an earphone box, and the specific structure of the earphone box is not limited in the present embodiment. In this embodiment, the method for communication between the earphone and the earphone box includes:
Step S10, ultrasonic ranging is carried out through an ultrasonic transmitting module and an ultrasonic receiving module in the earphone box, and a measured distance is obtained;
In many application scenarios, the earphone box is required to perform in-box detection (also referred to as in-place detection) on the earphone device, so as to perform corresponding operations according to the detection result, for example, in one application scenario, the earphone box is required to detect whether the earphone device is in a box state, and if so, perform charging operations on the earphone device. In the present embodiment, it is not limited to which scene is specifically applied.
In this embodiment, at least one ultrasonic transmitting module and at least one ultrasonic receiving module are disposed in the earphone box, and the earphone box is detected in the box by the ultrasonic transceiving functions of the ultrasonic transmitting module and the ultrasonic receiving module, so as to avoid the physical contact point. The positions at which the ultrasonic wave transmitting module and the ultrasonic wave receiving module are disposed may be positions at which the ultrasonic wave signals transmitted by the earphone device can be received by the earphone device when the earphone device is placed in the earphone box, and particularly, the present embodiment is not limited. The ultrasonic wave transmitting module and the ultrasonic wave receiving module may be implemented by any device capable of transmitting and receiving ultrasonic wave signals, which is not limited herein. The earphone device may include one earphone or two earphones; if two earphones are included, an ultrasonic receiving module and an ultrasonic transmitting module can be arranged in the earphone box aiming at one earphone so as to communicate with the earphone, and the other earphone communicates with the first earphone through Bluetooth or other modes; or if two earphones are included, the ultrasonic receiving module and the ultrasonic transmitting module can be respectively arranged in the earphone box for the two earphones so as to respectively communicate with the two earphones.
The earphone box can perform ultrasonic ranging through the ultrasonic transmitting module and the ultrasonic receiving module so as to determine whether the earphone device is in a box state according to the measured distance. The ultrasonic ranging through the ultrasonic transmitting module and the ultrasonic receiving module may specifically be based on the ultrasonic receiving-transmitting time interval to calculate the measured distance, and the specific calculation process is not described herein. In an embodiment, when the earphone device includes two earphones, the earphone box may determine that the two earphones are in a box state by ultrasonic ranging for the two earphones, respectively, based on the ultrasonic receiving module and the ultrasonic transmitting module respectively provided for the two earphones.
Step S20, if the measured distance is smaller than a first preset threshold value, modulating according to a preset ultrasonic modulation rule to obtain an ultrasonic handshake signal;
After the measured distance is obtained through ultrasonic ranging, the earphone box can detect whether the measured distance is smaller than a first preset threshold value. The first preset threshold may be set according to actual needs, and when the measurement distance is smaller than the threshold, it indicates that an object approaches the earphone box, for example, may be set to 0.5cm. If the measured distance is smaller than the first preset threshold value, the earphone device can obtain an ultrasonic handshake signal through modulation according to a preset ultrasonic modulation rule. The preset ultrasonic modulation rule may be an ultrasonic waveform modulation rule set in advance according to needs, and the rule may agree with information carried by different ultrasonic waveforms, that is, according to the rule, information to be transmitted may be converted into a corresponding ultrasonic signal (an ultrasonic waveform), or according to the rule, the ultrasonic signal may be resolved into corresponding information, so that both communication parties may communicate by means of transmitting and receiving ultrasonic waves. The ultrasonic handshake signal modulated according to the preset ultrasonic modulation rule is an ultrasonic signal carrying handshake request information, the handshake request information is used for indicating a communication partner to wish to establish communication connection through handshake, and after the communication partner receives the handshake request information, the communication partner can feed back confirmation information to indicate the communication partner to wish to establish communication connection.
In an embodiment, when the earphone device includes two earphones, and the earphone box respectively performs ultrasonic ranging to the two earphones, the earphone box can acquire two measured distances, and as long as one measured distance is smaller than a first preset threshold, it is indicated that an object is close to the earphone box, and at this time, the earphone box can modulate according to a preset ultrasonic modulation rule to obtain an ultrasonic handshake signal.
Step S30, an ultrasonic handshake signal is transmitted through an ultrasonic transmitting module, so that after the earphone equipment receives the ultrasonic handshake signal through a microphone, an ultrasonic feedback signal is transmitted through a loudspeaker;
After the earphone box is modulated to obtain an ultrasonic handshaking signal, the ultrasonic handshaking signal is transmitted through the ultrasonic transmitting module. If the object approaching the earphone box is an earphone device, the earphone device can receive the ultrasonic handshake signal through the microphone. Wherein, the earphone device can be provided with a loudspeaker with an ultrasonic wave transmitting function and a microphone with an ultrasonic wave receiving function. After receiving the ultrasonic handshake signals, the earphone equipment can analyze the ultrasonic handshake signals according to a preset ultrasonic modulation rule to obtain handshake request signals sent by the earphone box, generate confirmation information based on the handshake request signals, and modulate according to the preset ultrasonic modulation rule to obtain ultrasonic feedback signals corresponding to the confirmation information, wherein the ultrasonic feedback signals are ultrasonic signals carrying the confirmation information; after the modulation, an ultrasonic feedback signal may be emitted through a speaker.
In step S40, if the ultrasonic feedback signal emitted by the earphone device is received by the ultrasonic receiving module, it is determined that the earphone device is in the box state.
If the earphone box receives the ultrasonic feedback signal transmitted by the earphone device through the ultrasonic receiving module, the earphone device is an object close to the earphone box, and at the moment, the earphone box can determine that the earphone device is in a box state. Specifically, after receiving the ultrasonic feedback signal, the earphone box may analyze the ultrasonic feedback signal according to a preset ultrasonic modulation rule to obtain acknowledgement information carried by the ultrasonic feedback signal, and when determining that the acknowledgement information, that is, acknowledgement information fed back by the earphone device based on the received handshake request signal, it may be determined that the earphone device is in a box state.
When the measured distance is smaller than a first preset threshold value, the fact that an object is close to the earphone box is indicated, but the earphone box cannot determine that the object is the earphone equipment, so that the earphone box further sends an ultrasonic handshake signal through the ultrasonic transmitting module, and when an ultrasonic feedback signal can be received, the earphone equipment is determined to be in a box state, and the accuracy of earphone box detection is guaranteed.
In this embodiment, by setting the ultrasonic transmitting module and the ultrasonic receiving module in the earphone box, performing ultrasonic ranging through the ultrasonic transmitting module and the ultrasonic receiving module to obtain a measurement distance, if the measurement distance is smaller than a first preset threshold, modulating according to a preset ultrasonic modulation rule to obtain an ultrasonic handshake signal, transmitting the ultrasonic handshake signal through the ultrasonic transmitting module, so that after the earphone device receives the ultrasonic handshake signal by using the microphone, transmitting an ultrasonic feedback signal by using the loudspeaker, and if the ultrasonic feedback signal transmitted by the earphone device is received by using the ultrasonic receiving module, determining that the earphone device is in a box state, thereby realizing the in-box detection function of the earphone. Because the earphone box is through ultrasonic wave transmission module and ultrasonic wave receiving module carrying out ultrasonic ranging and signal transmission and realize the interaction between wireless earphone and the earphone box, so need not to set up the physical contact point, promoted the overall stability of wireless earphone and earphone box.
Further, in an embodiment, the earphone box may perform ultrasonic ranging through the ultrasonic transmitting module and the ultrasonic receiving module at regular intervals, so as to perform in-box detection on the earphone device, where the interval duration may be set according to needs, for example, to improve accuracy of detection, a smaller time interval may be set, and to reduce power consumption of the earphone box, a longer time interval may be set. Further, in an embodiment, in order to avoid power consumption of the earphone box caused by ultrasonic ranging when the earphone box is still in the box state, the earphone box may not perform the in-box detection after determining that the earphone box is in the box state, and may restart the in-box detection when determining that the earphone box is not in the box state. The method of determining that the earphone device is in the non-box state by the earphone box is not limited herein, for example, when the earphone box does not receive the state information sent by the earphone device for a continuous period of time in the process of communicating with the earphone device through the ultrasonic signal, the earphone device can be considered to be separated from the earphone box, that is, to be in the non-box state.
Further, in an embodiment, after step S10, the method further includes:
And a step a of returning to execute ultrasonic ranging through an ultrasonic transmitting module and an ultrasonic receiving module in the earphone box to obtain the measured distance if the measured distance is larger than a first preset threshold value or if an ultrasonic feedback signal transmitted by the earphone device is not received within a preset time after an ultrasonic handshake signal is transmitted.
After the earphone box obtains the measurement distance, if the measurement distance is greater than a first preset threshold value, the earphone box indicates that no object is close to the earphone box, the earphone box can determine that the earphone box is in an absent box state, and at the moment, the earphone box can continue to perform ultrasonic ranging. If the earphone box does not receive the ultrasonic feedback signal emitted by the earphone device within the preset time after emitting the ultrasonic handshake signal, the earphone box indicates that an object close to the earphone box is not the earphone device, the earphone box can also determine that the earphone box is not in an absent box state, and at the moment, the earphone box can continue to perform ultrasonic ranging.
Further, based on the above-mentioned first embodiment, a second embodiment of the communication method between an earphone and an earphone box according to the present invention is provided, and in this embodiment, after step S40, the method further includes:
step S50, when the earphone equipment is determined to be in a box state, modulating according to a preset ultrasonic modulation rule to obtain an ultrasonic communication signal corresponding to the target communication content;
in this embodiment, when the earphone box determines that the earphone device is in the box state, communication with the earphone device may be continued through the ultrasonic wave transmitting module and the ultrasonic wave receiving module, so as to implement information interaction between the earphone device and the earphone box when the earphone device is in the box state.
Specifically, the earphone box may modulate according to a preset ultrasonic modulation rule to obtain an ultrasonic communication signal corresponding to the target communication content. The target communication content may be information content to be transmitted by the earphone box to the earphone device, for example, may be a power information confirmation request, earphone state confirmation information, or the like, and is not limited in this embodiment. The modulated ultrasonic communication signal is the ultrasonic signal carrying the target communication content.
Step S60, the ultrasonic communication signal is sent to the earphone device through the ultrasonic transmission module, so that the earphone device can analyze the ultrasonic communication signal to obtain target communication content after receiving the ultrasonic communication signal through the microphone.
After the earphone box obtains the ultrasonic communication signal, the ultrasonic communication signal is sent to the earphone device through the ultrasonic transmitting module. The earphone device receives the ultrasonic communication signal by using the microphone, analyzes the ultrasonic communication signal according to a preset ultrasonic modulation rule to obtain target communication content, and further, the earphone device can perform corresponding feedback operation based on the target communication content, for example, feedback corresponding communication content to the earphone box.
In this embodiment, when the earphone box determines that the earphone device is in the box state, the earphone box communicates with the earphone device through the ultrasonic wave transmitting module and the ultrasonic wave receiving module, and information interaction between the earphone box and the earphone device can be completed without setting a physical contact point, so that the overall stability of the wireless earphone and the earphone box is improved.
Further, in an embodiment, when the target communication content is a power information confirmation request, after step S60, the method further includes:
step S70, receiving ultrasonic electric quantity signals transmitted by the earphone equipment, wherein the ultrasonic electric quantity signals are transmitted by the loudspeaker after the earphone equipment analyzes the electric quantity information confirmation request;
The target communication may be a power information confirmation request for indicating to the headset device that it is desired to obtain the current power value of the headset device. After the earphone equipment analyzes the electric quantity information confirmation request, the current electric quantity value can be obtained from an electric quantity management module in the earphone equipment, and an ultrasonic electric quantity signal corresponding to the electric quantity value is obtained by modulating according to a preset ultrasonic modulation rule, wherein the ultrasonic electric quantity signal carries the ultrasonic signal of the electric quantity value; the earphone device emits the ultrasonic power signal using a speaker.
The earphone box receives ultrasonic electric quantity signals transmitted by the earphone device through the ultrasonic receiving module.
Step S80, analyzing the ultrasonic electric quantity signal to obtain an electric quantity value of the earphone equipment;
After the earphone box receives the ultrasonic electric quantity signal, the ultrasonic electric quantity signal can be analyzed according to a preset ultrasonic signal modulation rule to obtain an electric quantity value of the earphone device. The earphone box can judge whether the earphone equipment needs to be charged or not according to the analyzed electric quantity value. In particular, the earphone box may compare the electrical quantity value with a second preset threshold. The second preset threshold value can be set according to needs, and when the electric quantity value is smaller than the second preset threshold value, the fact that the current electric quantity of the earphone device is insufficient is indicated, and charging is needed.
Step S90, if the electric quantity value is smaller than a second preset threshold value, the transmitting coil in the earphone box is controlled to be connected with the power supply device of the earphone box so as to charge the earphone device through the transmitting coil and the receiving coil in the earphone device.
If the electric quantity value is smaller than the second preset threshold value, the earphone box can control the transmitting coil in the earphone box to be connected with the power supply device in the earphone box so as to generate electromagnetic induction through the transmitting coil and the receiving coil arranged in the earphone device, and the earphone device is charged based on the principle of the electromagnetic induction.
