Description
Technical Field
The invention belongs to the technical field of earphone equipment, and particularly relates to an earphone and a control method of the earphone.
Background
The in-ear type Bluetooth earphone is a popular earphone in recent years, and is popular with consumers because of the characteristics of wireless transmission, small volume, suitability for wearing and the like. Because the earphone is not connected to other electronic equipment through a connecting wire, and electric energy cannot be obtained from electronic equipment such as a smart phone and a tablet personal computer, the earphone must be internally provided with a battery to solve the problem of power supply.
However, since the earphone has a small volume and a small built-in battery volume, the battery capacity is limited, which often results in that the earphone cannot be used for a long time and needs to be charged after being used for a period of time, thus causing inconvenience to users. Therefore, most of the existing in-ear bluetooth headsets are provided with an in-ear detection function, when the in-ear bluetooth headset is detected to be really placed in an ear, the function of playing music and other power consumption is started, and once the headset is taken down from the ear, the music playing function is closed, so that the power consumption of the headset is reduced, and the cruising ability of the headset is prolonged.
The existing in-ear bluetooth in-ear detection methods mainly include the following three types: the first is to use an optical sensor to cooperate with a motion acceleration sensor to realize the in-ear detection, which has high material cost and complex production process. The second mode is to use a photoelectric sensor or a photoelectric device to realize in-ear detection, the production cost of the earphone using the mode is lower than that of the first mode, but the photoelectric sensor or the photoelectric device has relatively high power consumption, the assembly process of the earphone is complex due to strong association with the shell, and the in-ear bluetooth earphone using the mode is not many. The third mode is to use a capacitance induction type sensor to realize in-ear detection, the earphone production cost of the mode is not high, the power consumption of the earphone is low, and the earphone can be shared with other detection functions, so that most of in-ear Bluetooth earphones adopt the mode at present.
As shown in fig. 1, the in-ear bluetooth headset using the third detection mode has a housing 10, a main control circuit board 12 is disposed in the housing 10, a charging interface 11 is disposed at one end of the housing 10, the charging interface 11 is connected to the main control circuit board 12, a power circuit is disposed on the main control circuit board 12, and an external power source received by the charging interface 11 supplies power to a battery 17 after voltage stabilization and filtering of the power circuit.
A horn 16 is provided in the housing 10, and a sound conduction port 15 is provided in the housing 10, the sound conduction port 15 being provided directly in front of the horn 16. The main control circuit board 12 is provided with an audio output circuit, the audio output circuit is electrically connected with the loudspeaker 16 through two audio transmission lines 14, and audio signals are transmitted to the loudspeaker 16 through the audio transmission lines 14.
In the case 10, an inductive electrode is further required to be disposed, in the existing in-ear bluetooth headset, a copper foil, a flexible PCB, etc. are disposed in the case 10 as the inductive electrode 13, and the inductive electrode 13 is required to be connected to the main control circuit board 12 through a capacitive sensing line 18. However, this requires a separate sensing electrode 13 in the housing 10, which increases the production cost of the in-ear bluetooth headset, especially the cost of the flexible PCB is high, and is not good for the miniaturization of the headset.
In addition, in order to achieve the capacitance detection effect and avoid affecting the main functions of the earphone, the sensing electrode 13 must be manually attached to a proper position inside the casing 10, for example, to the inner side surface of the sidewall of the casing 10, by a special process, which increases the process cost.

Detailed Description
The first embodiment:
referring to fig. 2, the earphone of the present invention is an in-ear bluetooth earphone, and the earphone of the present embodiment has a housing 20, where the housing 20 includes a cylindrical portion and a spherical portion, and the two portions are communicated with each other, where a main control circuit board 22 is disposed in the cylindrical portion, and in the present embodiment, a single chip, a power circuit, an audio output circuit, a capacitance sensing circuit, a bluetooth chip, and the like are disposed on the main control circuit board 22, and the circuits may be implemented by known circuits, and a detailed description of the present embodiment is omitted.
Be provided with the interface 21 that charges in the one end of casing 20, the interface 21 that charges is connected to main control circuit board 22's power supply circuit through the electricity connecting wire, and power supply circuit can carry out filtering, steady voltage etc. to the outside power of receiving. A battery 27 is provided within the housing 20, preferably the battery 27 is a rechargeable battery, and a power circuit can supply power to the battery 27. When the in-ear bluetooth headset is charged, the battery 27 stores electric energy, and when the charging interface 21 of the in-ear bluetooth headset does not receive an external power source, the battery 27 can supply power to the electronic device on the main control circuit board 22.
The horn 26 is arranged in the shell 20, the horn 26 of the present embodiment has a metal shell, and preferably, the shell of the horn 26 is made of copper, so that when the metal shell of the horn 26 is used as an induction electrode, the change of capacitance can be better induced, thereby determining the gesture of a user, and making the detection of the gesture of the user more accurate.
Loudspeaker 26 is connected to the audio output circuit of main control circuit board 22 through two audio transmission lines electricity, and after the bluetooth chip received the audio signal of the transmission of electronic equipment such as smart mobile phone, the singlechip audio signal decoded the back, exported loudspeaker 26 through audio output circuit and audio transmission line, loudspeaker 26 broadcast audio signal. The sound conduction port 25 is arranged right in front of the speaker 26, the sound conduction port 25 of the present embodiment is arranged on the front wall of the housing 20, that is, the place closest to the ear canal after the in-ear bluetooth headset is placed in the ear, and the sound conduction port 26 is arranged right in front of the speaker 26, which is beneficial to the sound of the speaker 26 to smoothly pass through the sound conduction port 25.
The loudspeaker 26 of this embodiment is as the response electrode through the metal casing of self for detect user's gesture changes, consequently, set up first capacitance induction line 28 in casing 20, the both ends of first capacitance induction line 28 are connected to the metal casing of loudspeaker 26 and the electric capacity induction circuit on the main control circuit board 22 respectively, when user's hand touched the casing 20 of earphone, the electric capacity between user's hand and the metal casing of loudspeaker 26 changes, the change signal of electric capacity is detected to the electric capacity induction circuit on the main control circuit board 22, and then judge the state of earphone. Therefore, the single chip microcomputer can control the working state of the earphone according to the state of the earphone, for example, the earphone is controlled to enter a music playing mode or quit the music playing mode.
The control method of the headset will be described with reference to fig. 3. First, step S1 is executed to obtain a capacitance sensing signal from the capacitance sensing circuit, and determine a variation process of the capacitance sensing signal according to the obtained capacitance sensing signal. When the user holds the earphone with hands, the earphone is put into the ear, the earphone is held by the user with hands and put into the earphone, the user does not hold the earphone with hands, and the like, the capacitance sensing signals received by the capacitance sensing circuit are different.
For example, when the user does not hold the earphone and the earphone is not placed in the ear, the capacitance-sensing signal received by the capacitance-sensing circuit is a lower level signal, as shown in section a1 of fig. 4. When the user holds the earphone, the capacitance-sensing signal will generate a positive jump with a medium amplitude, as shown in section a2 of fig. 4, and the capacitance-sensing signal is the hand-held sensing signal.
If the user holds the earphone and puts it into the ear, the capacitive sensing signal will be superimposed again with a small amplitude forward jump on the basis of segment a2, as shown in segment A3 of fig. 4, where the capacitive sensing signal is the hold and in-ear sensing signal. When the earphone is stably placed in the ear, i.e. the hand of the user leaves the earphone and the earphone is in the ear, the capacitance sensing signal will generate a medium amplitude reverse jump and keep stable, as shown in section a4 of fig. 4, and the capacitance sensing signal at this time is an in-ear sensing signal.
If the user removes the headset from the ear, then, during the period when the user holds the headset and removes the headset from the ear, a positive jump of moderate amplitude will occur in the capacitance-sensing signal, as shown in section a5 of fig. 4. Then, the earphone is disengaged from the ear, and when the user holds the earphone, the capacitance-sensing signal will generate a small amplitude negative-going jump, as shown in section a6 of fig. 4. When the headset is stored in a box or table or in a pocket, the capacitance-sensing signal will generate a medium-amplitude negative-going transition, as shown in paragraph a7 of fig. 4.
Therefore, in step S1, it is necessary to obtain the change process of the capacitance-induced signal, for example, to determine whether the capacitance-induced signal is a low level signal for a long time, and if so, it indicates that the earphone is in the storage state and is not worn on the ear. For another example, the capacitance-sensing signal goes through the process from segment a1 to segment a4 in fig. 4 in a short time, and is maintained in the state of segment a4 for a long time, which indicates that the user wears the earphone in the ear. If the capacitance-sensing signal has gone through the period A4 to A7 in a short time, it indicates that the earphone is removed from the ear.
Therefore, step S2 determines whether the current state of the headset is in-ear state, i.e. whether the headset has experienced a state from a1 segment to a4 segment and stably maintained in a4 segment, if yes, the determination result of step S2 is yes, which indicates that the headset is currently plugged into the ear, at this time, step S3 is executed, the music playing mode is turned on, and the bluetooth chip receives the audio signal transmitted by the smartphone or the like and transmits the audio signal to the speaker.
If the result of the determination in step S2 is no, indicating that the earphone does not enter the ear, then step S4 is executed to determine whether the current state of the earphone is the storage state, i.e., whether the earphone has experienced the state from the a4 segment to the a7 segment and is stably maintained in the a7 segment, if so, then step S4 is executed to determine that the current state of the earphone is removed from the ear, may be placed in a pocket, or may be placed on a desktop or other places, at this time, step S5 is executed to stop the music playing mode, and the audio output circuit on the main control chip stops outputting audio signals to the speaker. Preferably, when the earphone is confirmed to be in the sleep state, the single chip microcomputer can enter the sleep mode so as to further reduce the power consumption of the earphone.
And finally, the singlechip executes the step S6 to judge whether the Bluetooth chip of the in-ear Bluetooth headset is disconnected with the Bluetooth of the electronic equipment, if so, the user does not use the Bluetooth headset for a long time, the control flow of the Bluetooth headset is finished, otherwise, the step S1 is returned, the capacitance sensing signal is obtained again, and the state of the headset is determined according to the change of the capacitance sensing signal.
Second embodiment:
referring to fig. 5, the earphone of this embodiment has a housing 30, the housing 30 includes a cylindrical portion and a spherical portion, the two portions are communicated with each other, wherein a main control circuit 32 is disposed in the cylindrical portion, and in this embodiment, a single chip, a power circuit, an audio output circuit, a capacitance sensing circuit, a bluetooth chip, and the like are disposed on the main control circuit board 32.
Be provided with the interface 31 that charges in the one end of casing 30, the interface 31 that charges is connected to the power supply circuit of main control circuit board 32 through electric connection line, and power supply circuit can carry out filtering, steady voltage etc. to the outside power of receiving. A battery 37 is provided within the housing 30 and a power circuit may supply power to the battery 37. When the in-ear bluetooth headset is charged, the battery 37 stores electric energy, and when the charging interface 31 of the in-ear bluetooth headset does not receive an external power source, the battery 37 can supply power to the electronic device on the main control circuit board 32.
The horn 36 is arranged in the shell 30, the horn 36 of the embodiment is provided with a metal shell, preferably, the shell of the horn 36 is made of copper, so that when the metal shell of the horn 36 is used as an induction electrode, the change of capacitance can be better induced, the gesture of a user can be determined, and the detection of the gesture of the user is more accurate.
The horn 36 of the present embodiment is used as a sensing electrode through its metal casing for detecting the gesture change of the user, and therefore, a first capacitive sensing line 38 is disposed in the casing 30, and two ends of the first capacitive sensing line 38 are respectively connected to the metal casing of the horn 36 and the capacitive sensing circuit on the main control circuit board 32.
In contrast to the first embodiment, the present embodiment further provides the auxiliary sensing electrode 40 in the housing 30, the auxiliary sensing electrode 40 being provided on the inner side surface of the housing, and as can be seen from fig. 5, the auxiliary sensing electrode 40 is provided on the inner surface of the rear wall of the housing 30, i.e., the inner side surface away from the sound conduction port 35. The auxiliary sensing electrode 40 also functions to detect a gesture of a user, for example, to detect a capacitance change between the user and the auxiliary sensing electrode 40, so that the capacitance sensing circuit on the main control circuit board 32 is connected to the auxiliary sensing electrode 40 through the second capacitance sensing line 41, and thus, the capacitance sensing circuit can obtain a capacitance signal change on the auxiliary sensing electrode 40.
Preferably, the auxiliary sensing electrode 40 may be a multiplexing electrode, that is, the auxiliary sensing electrode 40 uses a touch sensing electrode disposed on the inner surface of the housing 30, and thus, the auxiliary sensing electrode 40 is multiplexed with the touch sensing electrode, and preferably, the touch sensing electrode is a copper foil or a flexible circuit board, that is, the auxiliary sensing electrode 40 is made of a copper foil, or is made of a flexible circuit board directly.
The touch sensing electrode is used for detecting a gesture of a user, for example, the user clicks the back of the earphone or double clicks the back of the earphone, and therefore, a touch detection circuit is further disposed on the main control circuit board 32, and the touch detection circuit is connected to the touch sensing electrode through the second capacitance sensing line 41.
It can be seen that, in this embodiment, the metal casing of the speaker 36 is used as the first sensing electrode, and in addition, the touch sensing electrode is used as the auxiliary sensing electrode 40, and the capacitance sensing circuit actually obtains the capacitance sensing signal through two sensing electrodes, so that the detection of the capacitance sensing signal is more accurate.
When the user touches the casing 30 of the earphone, the capacitance between the user's hand and the metal shell of the speaker 36 changes, the capacitance between the user's hand and the auxiliary sensing electrode 40 also changes, and the capacitance sensing circuit on the main control circuit board 32 detects the change signal of the capacitance, thereby determining the state of the earphone. Therefore, the single chip microcomputer can control the working state of the earphone according to the state of the earphone, for example, the earphone is controlled to enter a music playing mode or quit the music playing mode.
In addition, since the auxiliary sensing electrode 40 is multiplexed with the touch sensing electrode, that is, the touch sensing electrode can acquire a touch signal of a user, for example, the user clicks or double-clicks the earphone, so that the single chip microcomputer can control the work of the earphone according to the signal acquired by the touch detection circuit, for example, adjusting the volume of the earphone, controlling the playing sequence or playing mode, and the like. Of course, the user can set the function realized by clicking or double clicking the earphone according to the preference of the user.
Therefore, the metal shell of the loudspeaker is used as the induction electrode, so that an independent induction electrode does not need to be arranged in the shell, the production cost of the earphone can be reduced, a complex processing technology is not needed, and the production efficiency of the earphone is improved.
Finally, it should be emphasized that the present invention is not limited to the above embodiments, and variations such as changes in the shape of the earphone shell, changes in the shape of the speaker, changes in the metal material used for the speaker housing, etc. should also be included in the protection scope of the claims of the present invention.
