Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When the user places the headset in the charging box for storage, the charging box can detect that the headset is placed in the charging box, so as to trigger the next action. For example, the earphone is connected with the mobile phone in a Bluetooth mode, and after the earphone is detected to be placed in the charging box, the Bluetooth connection between the earphone and the mobile phone can be disconnected. In the related art, a commonly used scheme for detecting whether the earphone is placed in the charging box is that the earphone is in communication connection with the charging box through the contact of the earphone and the communication contact of the charging box, and the communication connection is performed based on a certain communication protocol. Successful communication indicates that the headset and the charging box both detect the dropped state. However, after the electric quantity of the charging box is exhausted, the earphone is placed into the charging box, the transmission of the communication protocol loses the power source, the earphone and the charging box cannot be in communication connection, and the use state of the earphone is difficult to accurately detect, so that the subsequent use of the earphone is influenced.
In order to solve the problems, the invention provides a detection method, which is applied to an earphone, wherein the earphone is provided with an independent battery, and the normal work of the earphone is ensured by supplying power to the earphone through the battery of the earphone when the earphone is used at ordinary times. When the earphone is not used, the earphone can be placed in the charging box and used for charging the charging box. The charging box provides a space for placing the earphone in addition to charging the earphone. Referring to fig. 1, according to a first embodiment of the present invention, a detection method includes:
in step S10, the headphone receives external electric charge. There are three general external environments to which the headset is exposed, and specific external environments include that the headset is placed inside the charging box, that the headset is worn in the ear of a person, or that the headset is placed outside the charging box and the user does not wear the headset. In each of these three external environments, the headset receives a different amount of charge and therefore a different capacitance value.
Step S20, generating a capacitance value according to the charges, and comparing the capacitance value with a preset first preset capacitance; the earphone is internally provided with a capacitance detection module, and the number of charges acquired to the outside of the earphone can be detected through the capacitance detection module. The human body can electrically conduct, so that when the earphone is worn in the ear of a person, the capacitance detection module can acquire electric charges from the human body. The earphone is placed outside the charging box, and under the condition that the user does not wear the earphone, the capacitance detection module is difficult to obtain electric charge, and the capacitance value can be considered to be basically zero at the moment. In addition, a capacitor is arranged in the charging box and can store electric charges, when the earphone is placed in the charging box, the earphone is communicated with the charging box, and the electric charge provided by the capacitor in the charging box is acquired by the capacitance detection module. The earphone is characterized in that a first processing module is further arranged inside the earphone and comprises a central processing unit and a storage, and a first preset capacitor is stored in the storage. Generally, the amount of charge provided by the capacitor in the charging box is the largest, and the least amount of charge is obtained when the headset is not worn in the position of the human ear and is placed outside the charging box. The capacitance obtained when the headset is worn in the position of the human ear is between the two cases, because the human body can provide the electric charge.
Step S30, if the capacitance is greater than or equal to the first predetermined capacitance, it is determined that the earphone is placed inside the charging box. The first preset capacitor is set to be equal to the number of charges released by the charging box to the earphone, and therefore when the capacitance value obtained by the earphone is larger than or equal to the first preset capacitor, the earphone is judged to be placed in the charging box. So that the next operation of the headset can be performed, for example, the bluetooth connection is disconnected and the sound is stopped. In addition, the first preset capacitance can be set in a changing way according to the quantity of the charges stored in the capacitor in the charging box.
In the technical scheme provided by the embodiment, the charges of the charging box can be independently stored without being connected with a power supply of the charging box. The earphone can obtain external capacitance value, and the earphone is under different external environment, and the capacitance value that obtains is of different size. The earphone compares the obtained capacitance value with the first preset capacitance, the charge value provided by the charging box is larger, and the detected capacitance value is also larger. If the capacitance value is larger than the first preset capacitance, the earphone can be judged to be placed in the charging box at present, and the earphone can perform the next action. Therefore, according to the technical scheme, even when the electric quantity of the charging box is exhausted, the use state of the earphone can be accurately detected, the earphone is placed in the charging box, and the normal use of the earphone is further ensured.
Referring to fig. 2, in the first embodiment of the present invention, it is difficult to determine whether the earphone is worn at the position of the human ear or placed outside the earphone case. To this end, a second embodiment of the invention is proposed on the basis of the first embodiment. After the step of comparing the capacitance value with a preset first preset capacitance, the method comprises the following steps:
step S40, if the capacitance value is smaller than the first preset capacitance, comparing the capacitance value with a preset second preset capacitance, wherein the first preset capacitance is larger than the second preset capacitance; when the earphone is worn in the ear of a person, the capacitance detection module can acquire charges from the human body, and the second preset capacitance is set to be lower than the capacitance formed by acquiring the charges from the human body. Due to the individual difference of the human body, the second preset capacitance may be set lower than the average value of the capacitances obtained from the human body, or may be set lower than the lowest value of the capacitances obtained from the human body. In addition, the second preset capacitor can be changed and set according to the individual condition of the user.
Step S41, if the capacitance value is larger than the second preset capacitance and smaller than the first preset capacitance, the earphone is judged to be worn on the ear of the person; at this time, the capacitance value obtained by the earphone is between the second preset capacitance and the first preset capacitance, which indicates that the electric charge obtained by the earphone comes from the human body, and thus, the earphone is judged to be worn on the ear of the person.
Step S42, if the capacitance is smaller than or equal to the second predetermined capacitance, it is determined that the earphone is not worn on the ear and the earphone is disposed outside the charging box. When the earphone is not worn on the ear of a person and the earphone is placed outside the charging box, the quantity of electric charges which can be acquired by the earphone is small. At this time, the charge that the earphone can acquire comes from the surrounding large air environment. Basically the charge in air comes from the ionization of gas molecules, which is extremely rare and thus the amount of charge in the air environment is extremely weak. If the capacitance value obtained by the earphone is smaller than or equal to the second preset capacitance, the earphone is not worn on the ear of the person, and the earphone is placed outside the charging box, namely, the earphone is idle outside the charging box at the moment.
Referring to fig. 3, the usage state of the charging box includes a power-rich state and a power-depleted state, so that the usage state of the charging box can be accurately detected. On the basis of the first embodiment of the present invention, a third embodiment of the present invention is proposed. After the step of comparing the capacitance value with a preset first preset capacitance, the method further comprises the following steps:
step S50, if the capacitance value is smaller than the first preset capacitance, the earphone detects whether the connection request of the charging box is received; and a switch module is also arranged in the charging box and used for controlling the capacitor to be connected or disconnected. When the capacitor is switched on, the charge can be released, and when the capacitor is switched off, the charge of the capacitor cannot be released outwards. In the case that the switch module is turned off, the capacitor is turned on, and at this time, as in step S30, the capacitance value is greater than or equal to the second preset capacitance, it can be determined that the earphone is placed inside the charging box. And the capacitance value is smaller than the first preset capacitance, two conditions exist. In one case, the headset is placed in the charging box, but the switch module is on. In another case, the earphone is placed outside the charging box, and the capacitance value is smaller than the first predetermined capacitance because the earphone is separated from the charging box and the charge of the capacitor cannot be obtained. In addition, if the charging box has enough power, the charging box actively sends a connection request to the earphone. The earphone can receive the connection request in such a way that the earphone and the charging box are in contact with each other, and the earphone is placed in the charging box.
Step S51, if the connection request of the charging box is detected, the earphone is judged to be arranged in the charging box, and the charging box finishes the charging recovery work; if the earphone receives the connection request sent by the charging box, the earphone is placed in the charging box. In addition, the charging box does not have sufficient power source to provide power to send the connection request signal in the event of a power exhaustion. Therefore, it is also stated that the charging box can transmit a connection request signal to the headset when the charging box has a sufficient amount of power.
In step S52, if the connection request of the charging box is not detected, it is determined that the earphone is placed outside the charging box. Therefore, under the condition that the connection request of the charging box is not detected, and the capacitance value obtained by the earphone is smaller than the first preset capacitance, the earphone can be judged to be placed outside the charging box.
Referring to fig. 4, a fourth embodiment of the present invention is proposed on the basis of the above-described embodiment. In the case of using a headset, a user typically makes a wireless connection between the headset and an audio playing device. For example, the headset and smartphone are bluetooth connected. However, after the headset is used, the user sometimes forgets to cancel the bluetooth connection. This results in the headset and smartphone being continuously connected and the power to the headset being continuously consumed. And because the earphone is connected with the smart phone, when a user makes a call, the user cannot hear the voice content directly through the smart phone, which also brings inconvenience to the user. Therefore, the step of determining that the earphone is placed inside the charging box includes:
in step S60, the earphone disconnects the wireless connection with the outside. By determining that the headset has been placed in the charging box, it can be determined that the user does not need to use the headset at this time. Therefore, the earphone is actively disconnected from the external wireless connection. Therefore, the power consumption of the earphone is avoided being consumed without reason, and the normal use of the audio playing equipment by a user is also ensured.
Referring to fig. 5, the present invention further provides a detection method, where the detection method is applied to a charging box, and the charging box is used for charging an earphone, and the detection method includes:
step S110, the charging box sends charges to the earphone, wherein the earphone receives the charges, the earphone generates a capacitance value according to the charges, the capacitance value is compared with a preset first preset capacitor, and if the capacitance value is larger than or equal to the first preset capacitor, the earphone generates a feedback signal; be provided with the condenser in the box that charges, be provided with electric capacity detection module in the earphone, can detect the capacitance value of acquireing to the earphone outside through electric capacity detection module. There are three general external environments to which the headset is exposed, and specific external environments include that the headset is placed inside the charging box, that the headset is worn in the ear of a person, or that the headset is placed outside the charging box and the user does not wear the headset. In each of these three external environments, the headset receives a different amount of charge and therefore a different capacitance value. The human body can electrically conduct, so that when the earphone is worn in the ear of a person, the capacitance detection module can acquire electric charges from the human body. The earphone is placed outside the charging box, and under the condition that the user does not wear the earphone, the capacitance detection module is difficult to obtain electric charge, and the capacitance value can be considered to be basically zero at the moment. In addition, a capacitor is arranged in the charging box and can store electric charges, when the earphone is placed in the charging box, the earphone is communicated with the charging box, and the electric charge provided by the capacitor in the charging box is acquired by the capacitance detection module. The earphone is characterized in that a first processing module is further arranged inside the earphone and comprises a central processing unit and a storage, and a first preset capacitor is stored in the storage. Generally, the amount of charge provided by the capacitor in the charging box is the largest, and the least amount of charge is obtained when the headset is not worn in the position of the human ear and is placed outside the charging box. The capacitance obtained when the headset is worn in the position of the human ear is between the two cases, because the human body can provide the electric charge. Through setting for first predetermined capacitance, first predetermined capacitance equals the electric charge number that the box released to the earphone that charges, from this when the capacitance value that the earphone obtained is greater than or equal to first predetermined capacitance, the earphone generates feedback signal, and the feedback signal is greater than or equal to the condition of first predetermined capacitance including the capacitance value in the feedback signal, and the earphone transmits feedback signal to the box that charges.
Step S210, the charging box receives a feedback signal sent by the earphone, the earphone is placed in the charging box, and the earphone and the charging box are in mutual contact. For example, the earphone is provided with a first data contact, the charging box is provided with a second data contact corresponding to the first data contact, and the earphone can transmit the generated feedback signal to the charging box through the contact of the first data contact and the second data contact.
Step S310, the charging box judges that the charging box contains the earphone according to the feedback signal. The second processing module is arranged in the charging box, and after the charging box receives the feedback signal, the second processing module judges that the charging box is used for containing the earphone according to the received feedback signal. Of course, the first preset capacitance may also be stored in the second processing module, so that the charging box only needs to receive the capacitance value obtained by the earphone.
Referring to fig. 6, the present invention further provides a detection method, where the detection method is applied to an audio component, the audio component includes an earphone and a charging box, the earphone is charged by using the charging box, and the detection method includes:
in step S1, the charging box sends the charge to the headset. The charging box is internally provided with a capacitor which can store charges, the earphone is internally provided with a capacitance detection module, the capacitance detection module can receive the charges outside the earphone, and the obtained charges are converted into capacitance values representing the number of the charges. There are three general external environments to which the headset is exposed, and specific external environments include that the headset is placed inside the charging box, that the headset is worn in the ear of a person, or that the headset is placed outside the charging box and the user does not wear the headset. In each of these three external environments, the headset receives a different amount of charge and therefore a different capacitance value. The human body can electrically conduct, so that when the earphone is worn in the ear of a person, the capacitance detection module can acquire electric charges from the human body. The earphone is placed outside the charging box, and under the condition that the user does not wear the earphone, the capacitance detection module is difficult to obtain electric charge, and the capacitance value can be considered to be basically zero at the moment.
In step S2, the earphone receives the charges, generates a capacitance value according to the charges, and compares the capacitance value with a preset first preset capacitance. When the earphone is placed in the charging box, the earphone is communicated with the charging box, and the capacitance detection module acquires the charge provided by the capacitor in the charging box. The earphone is characterized in that a first processing module is further arranged inside the earphone and comprises a central processing unit and a storage, and a first preset capacitor is stored in the storage. Generally, the amount of charge provided by the capacitor in the charging box is the largest, and the least amount of charge is obtained when the headset is not worn in the position of the human ear and is placed outside the charging box. The capacitance obtained when the headset is worn in the position of the human ear is between the two cases, because the human body can provide the electric charge.
And step S3, when the capacitance value is larger than or equal to the first preset capacitance, the earphone is judged to be arranged in the charging box. The first preset capacitor is set to be equal to the number of charges released by the charging box to the earphone, and therefore when the capacitance value obtained by the earphone is larger than or equal to the first preset capacitor, the earphone is judged to be placed in the charging box. So that the next operation of the headset can be performed, for example, the bluetooth connection is disconnected and the sound is stopped. In addition, the first preset capacitance can be set in a changing way according to the quantity of the charges stored in the capacitor in the charging box.
Referring to fig. 7, the present invention further provides an audio assembly, the audio assembly includes an earphone and a charging box, the earphone is charged by the charging box, and the earphone includes: the device comprises a capacitance detection module and a first processing module.
The capacitance detection module is arranged in the earphone and used for receiving external charges and generating a capacitance value according to the charges; there are three general external environments to which the headset is exposed, and specific external environments include that the headset is placed inside the charging box, that the headset is worn in the ear of a person, or that the headset is placed outside the charging box and the user does not wear the headset. In each of these three external environments, the headset receives a different amount of charge and therefore a different capacitance value. The human body can electrically conduct, so that when the earphone is worn in the ear of a person, the capacitance detection module can acquire electric charges from the human body. The earphone is placed outside the charging box, and under the condition that the user does not wear the earphone, the capacitance detection module is difficult to obtain electric charge, and the capacitance value can be considered to be basically zero at the moment. In addition, a capacitor is arranged in the charging box and can store electric charges, when the earphone is placed in the charging box, the earphone is communicated with the charging box, and the electric charge provided by the capacitor in the charging box is acquired by the capacitance detection module.
First processing module locates in the earphone, and first processing module electric connection is in electric capacity detection module, and first processing module is used for comparing the capacitance value with the first predetermined electric capacity of predetermineeing, and the capacitance value is greater than or equal to the first predetermined electric capacity, judges that the earphone is arranged in the inside of charging the box. The first processing module comprises a central processing unit and a memory, and a first preset capacitor is stored in the memory. Generally, the amount of charge provided by the capacitor in the charging box is the largest, and the least amount of charge is obtained when the headset is not worn in the position of the human ear and is placed outside the charging box. The capacitance obtained when the headset is worn in the position of the human ear is between the two cases, because the human body can provide the electric charge. The first preset capacitor is set to be equal to the number of charges released by the charging box to the earphone, and therefore when the capacitance value obtained by the earphone is larger than or equal to the first preset capacitor, the earphone is judged to be placed in the charging box. So that the next operation of the headset can be performed, for example, the bluetooth connection is disconnected and the sound is stopped. In addition, the first preset capacitance can be set in a changing way according to the quantity of the charges stored in the capacitor in the charging box.
Furthermore, the earphone also comprises a conductive part, the conductive part is arranged at the sound outlet end of the earphone, and the conductive part is electrically connected with the capacitance detection module; when the user uses the earphone, the sound outlet end of the earphone faces the user, the conductive part can be close to the human body or attached to the human body, and therefore charges carried by the human body can be acquired through the conductive part. The conductive portion transfers the obtained electric charge to the capacitance detection module.
The charging box comprises a conductive contact and a first capacitor, the conductive contact is arranged corresponding to the conductive part, the first capacitor is arranged inside the charging box, and the first capacitor is electrically connected to the conductive contact. The contacting of the earphone and the charging box is done by the contacting of the conductive part and the conductive contact, the charge of the first capacitor being transmitted to the conductive part via the conductive contact, thereby completing the transfer of the charge in the capacitor.
The memory also stores a second preset capacitor. The first preset capacitor is larger than the second preset capacitor; when the earphone is worn in the ear of a person, the capacitance detection module can acquire charges from the human body, and the second preset capacitance is set to be lower than the capacitance formed by acquiring the charges from the human body. Due to the individual difference of the human body, the second preset capacitance may be set lower than the average value of the capacitances obtained from the human body, or may be set lower than the lowest value of the capacitances obtained from the human body. In addition, the second preset capacitor can be changed and set according to the individual condition of the user.
The capacitance value is larger than the second preset capacitance and smaller than the first preset capacitance, and then the earphone is worn on the ear of the person; at this time, the conductive part acquires the human body charge, and thus the capacitance value acquired by the earphone is between the second preset capacitor and the first preset capacitor, and further the charge acquired by the earphone comes from the human body, so that the condition that the earphone is worn on the ear of the person is judged.
And if the capacitance value is less than or equal to the second preset capacitance, the earphone is not worn on the ear of the person and is arranged outside the charging box. When the earphone is not worn on the ear of a person and the earphone is placed outside the charging box, the quantity of electric charges which can be acquired by the earphone is small. At this time, the electric charge that the earphone can acquire through the conductive portion comes from the surrounding large air environment. Basically the charge in air comes from the ionization of gas molecules, which is extremely rare and thus the amount of charge in the air environment is extremely weak. If the capacitance value obtained by the earphone is smaller than or equal to the second preset capacitance, the earphone is not worn on the ear of the person, and the earphone is placed outside the charging box, namely, the earphone is idle outside the charging box at the moment.
Further, referring to fig. 8, the earphone further includes a first data contact, the first data contact is disposed on an outer surface of the earphone, and the first data contact is electrically connected to the capacitance detection module; the earphone is provided with a first data contact point, a power connection point and a grounding point, wherein the first data contact point is used for conducting a data signal, the power connection point is used for transmitting power, and the grounding point is used for grounding.
The charging box comprises a second data contact and a second processing module, the second data contact is arranged corresponding to the first data contact, the second processing module is arranged in the charging box, a switch module is connected between the second processing module and the second data contact, the charging box further comprises a second capacitor, and the second capacitor is electrically connected to the switch module.
The second processing module also comprises a central processing unit and a memory, the switch module has two switching states, one is an opening state of the switch module under the condition that the charging box has sufficient electric quantity, at the moment, the electric charge of the second capacitor cannot be conducted to the second data contact, and the second processing module is communicated with the second data contact. At this time, since the second capacitor cannot communicate with the second data contact, the charge stored in the second capacitor cannot be conducted to the second data point, and the charge cannot be detected by the capacitance detection module in the earphone. The second is that the switch module is in a closed state, at this time, the second capacitor is connected, and charges can be sent out through the second capacitor. And the capacitance value is smaller than the first preset capacitance, two conditions exist. In one case, the headset is placed in the charging box, but the switch module is on. In another case, the earphone is placed outside the charging box, and the capacitance value is smaller than the first predetermined capacitance because the earphone is separated from the charging box and the charge of the capacitor cannot be obtained. In addition, if the charging box has enough power, the charging box actively sends a connection request to the earphone. The earphone can receive the connection request in such a way that the earphone and the charging box are in contact with each other, and the earphone is placed in the charging box.
If the connection request of the charging box is detected, the earphone is placed in the charging box, and the charging box finishes charging recovery work; if the earphone receives the connection request sent by the charging box, the earphone is placed in the charging box. In addition, the charging box does not have sufficient power source to provide power to send the connection request signal in the event of a power exhaustion. Therefore, it is also stated that the charging box can transmit a connection request signal to the headset when the charging box has a sufficient amount of power.
If the connection request of the charging box is not detected, the earphone is placed outside the charging box. Therefore, under the condition that the connection request of the charging box is not detected, and the capacitance value obtained by the earphone is smaller than the first preset capacitance, the earphone can be judged to be placed outside the charging box.
