In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The following describes the earphone provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
In one embodiment of the present application, a headset is provided, the headset including a processor, a sound module, and a detection module, the headset having an ear-entrance portion, the detection module being disposed on an outer surface of the ear-entrance portion. The processor is electrically connected with the sounding module and the detection module. The detection module is configured to detect whether the earphone is worn abnormally, for example, the detection module is configured to feed back voltage information to the processor, and the processor detects whether the earphone is worn abnormally through the voltage information. And under the condition that the earphone is worn abnormally, the processor increases a preset gain to the sounding module.
In this embodiment, the detection part of the detection module is located on the outer surface of the ear, and can detect whether the wearing of the earphone is abnormal. And can adjust the sound production module through the treater and predetermine the gain in order increasing, through the treater to sound production module increase promptly and predetermine the gain, adjust the sound production effect of sound production module to the sound that makes the user hear keeps original sound effect.
Optionally, the detection module can feed back voltage information of different wearing states of the headset under the wearing condition, and feed back the voltage information to the processor. For example, the detection unit of the detection module detects a voltage of a path formed by contact with the skin of the ear canal in which the ear insertion unit is located, from the outer surface of the ear insertion unit. The processor judges the wearing condition of the earphone according to the voltage information, and when the wearing of the earphone is abnormal, for example, the earphone is loose. The processor increases the preset gain to the sounding module, thereby adjusting the sounding effect of the sounding module.
The preset gain is a gain value set in the memory, the gain value which needs to be increased under different abnormal wearing conditions of the earphone is obtained through experimental tests, the gain value is written into the memory, and the processor writes the gain value into the sounding module corresponding to different abnormal conditions under the condition that the earphone is loosened. Specifically, the processor outputs the corresponding gain value of the preset gain to the sounding module in an electric signal compensation mode according to different abnormal conditions, so that the sound effect emitted by the sounding module achieves the effect of wearing under normal conditions. Wear unusually to indicate that the earphone is not hard up promptly, through to the emergence effect of presetting gain value adjustment sound production module in sound production module compensation, solve the not hard up earphone pronunciation effect that causes of earphone and worsen problem.
The gain value of the preset gain compensation is set according to the condition that the sound quality is damaged under the abnormal wearing condition of the earphone, for example, the gain value can be used for increasing the low-frequency effect of the sound generating module, also can be used for increasing the loudness of the sound generating module, and also can be other sound signals damaged under the abnormal wearing condition of the earphone, which can be thought by those skilled in the art.
As shown in fig. 2, the sound emitting module includes a digital-to-analog converter (DAC), an operational Amplifier (AMP), and a speaker. The sound signal of the earphone is sent out by the loudspeaker, and in the working process of the earphone, the processor needs to take out the information from the memory, then the information is subjected to digital-to-analog conversion by the digital-to-analog converter, and finally the information is amplified by the operational amplifier and output to the loudspeaker. Under the condition of increasing the preset gain, the processor takes out the gain value from the memory to be added to the original output signal and outputs the gain value to the loudspeaker so as to adjust the pronunciation effect of the loudspeaker.
In one embodiment, as shown in fig. 1 and 2, the ear insertion part 1 forms an inner cavity of the earphone, and the processor (CPU), the sound generating module and the detection module are all disposed in the inner cavity of the earphone. The inlet ear 1 has a sound outlet 10. The sound outlet of the sound module faces the sound outlet 10, and sound signals emitted by the sound module are transmitted to the outside of the earphone from the sound outlet 10.
The detection module comprises: a conducting contact 14 and a sensing contact. The conducting contact 14 is electrically connected with a GND end of a power module of the earphone, the detection contact is electrically connected with a VDD end of the power module, a detection resistor is connected between the detection contact and the VDD end in series, a voltage detection point is arranged on a connection line between the detection resistor and the detection contact, the processor is electrically connected with the voltage detection point, and the detection contact and the conducting contact 14 are located on the outer surface of the ear-entering part 1;
the voltage information fed back by the detection module comprises a voltage value of the voltage detection point, the earphone is worn abnormally under the condition that the voltage value of the voltage detection point is equal to a voltage value of a VDD (voltage source) terminal of the power module, and the processor adds a preset gain to the sounding module.
When a user normally wears the earphone, the outer surface of the ear-entering part 1 is contacted with the ear canal of the user, and the detection contact and the conducting contact 14 on the surface of the ear-entering part 1 are conducted with the skin of the human ear to form a loop. The detection resistor enables the voltage value of the voltage detection point detected by the processor to be smaller than the voltage value of the VDD terminal in the case where the detection contact is conductive with the conductive contact 14. When the detection contact and the conduction contact 14 are not conducted, the voltage value of the voltage detection point is equal to the voltage value of the VDD terminal.
The processor can obtain whether the detection contact and the conducting contact 14 are conducted or not by comparing the voltage value of the voltage detection point with the voltage value of the VDD end. When the detection contact and the conduction contact 14 are not conducted, it is determined that the fitting between the ear insertion part 1 and the ear canal is loose, and the wearing of the earphone is abnormal. When wearing unusual condition appearing, the gain is predetermine to the sound production module increase to the treater to adjustment sound production module sound production effect makes the sound effect that the object received who wears the earphone keep the sound effect of normally wearing, avoids the not hard up problem that causes the audio to worsen of earphone, has improved user experience.
The power supply module can be a separately arranged module or a power supply in an electronic system in the earphone.
In one embodiment, the conducting contact 14 is located in the lower region of the outer surface of the insertion part 1, and the detection contact is located in the upper region of the outer surface of the insertion part 1.
When the user wears the earphone, the upper region of the outer surface of the ear insertion part 1 is in contact with the upper region of the auditory canal, and the lower region of the ear insertion part 1 is in contact with the lower region of the auditory canal. The conductive contact 14 is located in the lower region of the outer surface of the ear-insertion part 1, so that the conductive contact 14 on the earphone to be worn can always be in contact with the ear canal under the influence of gravity.
After the processor receives the voltage value of the voltage detection point, the conduction condition of the detection contact and the conduction contact 14 can be judged by comparing the voltage value of the voltage detection point with the voltage value of the VDD end, and whether the detection contact is in contact with the auditory canal or not can be judged according to the conduction condition of the detection contact and the conduction contact 14. For example, when the processor determines that the voltage value of the voltage detection point is equal to the voltage value of the VDD terminal, the detection contact and the conducting contact 14 are not conducting, and it can be determined that the detection contact is not in contact with the ear canal, the wearing of the earphone is abnormal, and the earphone is loosened. And then the processor adds preset gain to the sounding module so as to adjust the sounding effect of the sounding module, so that the sound effect heard by the user is the same as the effect when the earphone is not loosened.
In one embodiment, the detection contacts include a first contact 11, a second contact 12, and a third contact 13, the detection resistors include a first resistor, a second resistor, and a third resistor, and the voltage detection points include a first detection point, a second detection point, and a third detection point;
the first contact 11 is electrically connected with the VDD terminal, the first resistor is connected in series between the first contact 11 and the VDD terminal, a first detection point is arranged between the first resistor and the first contact 11, and the processor is electrically connected with the first detection point. The processor is electrically connected with the first detection point, can detect the voltage of the first detection point at any time and feeds the voltage back to the processor.
The second contact 12 is electrically connected with the VDD terminal, the second resistor is connected in series between the second contact 12 and the VDD terminal, a second detection point is arranged between the second resistor and the second contact 12, and the processor is electrically connected with the second detection point. The processor is electrically connected with the second detection point, can detect the voltage of the second detection point at any time and feeds the voltage back to the processor.
The third contact 13 is electrically connected with the VDD terminal, the third resistor is connected in series between the third contact 13 and the VDD terminal, a third detection point is arranged between the third resistor and the third contact 13, and the processor is electrically connected with the third detection point. The processor is electrically connected with the third detection point, can detect the voltage of the third detection point at any time and feeds the voltage back to the processor.
Set up three contact of first contact 11, second contact 12 and third contact 13 on going into ear 1's surface, increased the position that can feedback voltage information, whether contact through judging three contact and the auditory canal can judge the not hard up degree of going in and out ear 1 and auditory canal more accurately. For example, the voltage values of the first detection point, the second detection point and the third detection point are fed back to the processor and are respectively compared with the voltage value of the VDD terminal. Therefore, whether the corresponding first contact 11, second contact 12 and third contact 13 are in contact with the auditory canal or not is obtained, and the corresponding gain values are set according to the contact conditions of the first contact 11, second contact 12 and third contact 13 with the auditory canal, so that the sound effect of the earphone can be adjusted under different loosening degrees, and finally, the sound effect heard by a user is the same as the sound effect under the normal wearing condition without loosening.
For example, when the processor detects that the voltage value of one of the first detection point, the second detection point and the third detection point is equal to the voltage value of the VDD terminal, the voltage values of the other two contacts are smaller than the voltage value of the VDD terminal. One of the first contact 11, the second contact 12 and the third contact 13 corresponding to the one detection point is not in contact with the ear canal. For example, the voltage value of the first detection point is smaller than the voltage value of the VDD terminal, the first contact 11 is not in contact with the ear canal. In this case, the earphone loosening degree is small. The processor starts the corresponding preset gain to adjust the sound effect of the sound production module, so that the sound production effect heard by the user is the same as that under the condition of not loosening.
For example, when the voltage value fed back to the processor by two of the first detection point, the second detection point and the third detection point is equal to the voltage value of the VDD terminal, two of the first contact 11, the second contact 12 and the third contact 13 are not in contact with the ear canal. The headset loosens more in this case than if one contact is not touching. The processor starts the corresponding preset gain to adjust the sound effect of the sound production module, so that the sound production effect heard by the user is the same as that under the condition of not loosening.
For example, when the voltage values fed back to the processor by the first detection point, the second detection point and the third detection point are all equal to the voltage value of the VDD terminal, the corresponding first contact 11, the second contact 12 and the third contact 13 are all not in contact with the ear canal. In this case, the earphone loosening degree is large. The processor starts the corresponding preset gain to adjust the sound effect of the sound production module, so that the sound production effect heard by the user is the same as that under the condition of not loosening.
Different preset gains are started to increase gain values to the sounding module under different loosening degrees, the preset gains under different loosening degrees can be obtained through testing and recorded in the memory, and the processor increases the gain values to the sounding module through the preset gains in the memory.
In one embodiment, the ear-in portion 1 has a sound outlet 10, and the first contact 11, the second contact 12 and the third contact 13 are arranged in sequence from a side of the outer surface of the ear-in portion 1 away from the sound outlet 10 to a side of the outer surface of the ear-in portion 10.
In this embodiment, in a state where the user wears the earphone, the sound outlet 10 side faces the inside of the ear canal, and the first contact 11 is closest to the outside of the ear canal.
In case only the first contact 11 is not in contact with the ear canal, the earpiece is less loose.
In case the second contact 12 is not in contact with the ear canal, the first contact 11 is also not in contact with the ear canal, and the looseness of the earphone is greater.
In the case where the third contact 13 is not in contact with the ear canal, the first contact 11 and the second contact 12 are also in a state of not being in contact with the ear canal, and the earphone has a larger looseness than the two cases described above in this embodiment.
Under the condition that the earphone has different looseness degrees, different contact points can be corresponding to the condition that the earphone is not contacted with the auditory canal. For example, under normal wear conditions, the first contact 11, the second contact 12 and the third contact 13 are all in contact with the ear canal. When loosening occurs, the first contact 11 is separated from the auditory canal, when the loosening degree is further increased, the second contact 12 is also separated from the auditory canal, and when the loosening degree is further increased, the third contact 13 is also separated from the auditory canal.
According to the comparison of the voltage values of the first detection point, the second detection point and the third detection point with the voltage value of the VDD end, the contact conditions of the first contact 11, the second contact 12 and the third contact 13 with the auditory canal can be obtained, and therefore the corresponding preset gain is enabled. In this embodiment, the first contact 11, the second contact 12 and the third contact 13 arranged in sequence simplify the difficulty of detecting the looseness by the processor, so that the sound effect of the earphone can be adjusted more effectively.
In one embodiment, the resistance value of the detection resistor is 5M omega-10M omega.
The resistance value of the human auditory canal skin is about 5M omega-10M omega, the detection resistance is set to be 5M omega-10M omega, under the condition that the detection contact is contacted with the auditory canal, the difference value between the voltage value fed back by the voltage detection point obtained by the processor and the voltage value at the VDD end can be larger, the detection sensitivity is improved, and the detection result is prevented from being influenced by the detection error.
In one example, the first resistor, the second resistor, and the third resistor have resistance values of 5M Ω to 10M Ω. In the resistance value range, under the condition that the first contact 11, the second contact 12 and the third contact 13 are in contact with the auditory canal, the voltage values of the first detection point, the second detection point and the third detection point can be ensured to have obvious voltage difference with the voltage value of the VDD end, and the detection sensitivity is improved.
