Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of earphones, and in particular to an earphone with an antenna peripheral device and an audio playing method. BACKGROUND

[0002] With the development of science and technology, wireless earphones are increasingly widely used due to their convenient portability and other characteristics. At present, most related earphones are rod-type earphones or bean-type earphones. Specifically, the battery, mainboard and antenna of the related earphones are arranged in the same cavity or connected cavities.

[0003] However, the inventors have found that when using the above earphones, the following technical problems often exist:

[0004] First, the battery, mainboard and antenna of the earphone are arranged in the same cavity or connected cavities, and the space in the earphone cavity is insufficient, resulting in a smaller size of the antenna that can be arranged in the cavity, which leads to a weaker signal of the earphone. In addition, since conductive materials have a shielding effect on signals, the battery, speaker and mainboard all include conductive materials, and the battery, speaker and mainboard generate certain electromagnetic interference waves when working, so arranging the antenna and the battery, speaker or mainboard in the same cavity will interfere with the reception of signals by the antenna, further leading to a weaker signal of the earphone.

[0005] Second, related wireless earphones mostly simultaneously perform noise reduction processing on audio in noise reduction mode, resulting in a higher power consumption of the two earphones, which leads to poor battery life of the earphones.

[0006] Third, related wireless earphones mostly collect a segment of environmental noise, directly simulate inverse sound waves on the basis of the segment of environmental noise, and perform noise reduction by offsetting, but this way of noise reduction has poor noise reduction effect in places where noise changes greatly, leading to poor user experience.

[0007] The above information disclosed in this BACKGROUND section is only for the purpose of enhancing the understanding of the background of the present inventive concepts, and therefore, it can contain information that does not form the prior art that is known to those of ordinary skill in the art in the country.

In addition, since the conductive material has a shielding effect on the signal, the battery, the loudspeaker and the mainboard all include conductive materials, and the battery, the loudspeaker and the mainboard will generate certain electromagnetic interference waves when working, so arranging the antenna, the battery, the loudspeaker or the mainboard in the same cavity will interfere with the reception of the antenna.

Because the ear handle connecting the sound cavity assembly and the battery assembly realizes the antenna function, the limitation of the earphone cavity on the size of the antenna is avoided, the size of the antenna can be appropriately increased, and the signal of the earphone can be enhanced. Therefore, the earphone of the antenna peripheral device of some embodiments of the present disclosure can use the ear handle to realize the antenna function, avoids the limitation of the earphone cavity on the size of the antenna, and makes the antenna greatly away from the battery, the loudspeaker and the mainboard, increases the area of the antenna contacting the signal source, thereby enhancing the signal receiving capability and signal stability of the antenna, and further enhancing the signal of the earphone.

The battery assembly 2 can be a component for providing power. The antenna ear stem 3 can be a stem connecting the acoustic cavity assembly 1 and the battery assembly 2 and serving as an antenna.

The front acoustic cavity 11 and the rear acoustic cavity 12 can be housings for holding an earphone main board 13 and a speaker 14. The front acoustic cavity 11 can be connected to the rear acoustic cavity 12. The specific manner in which the front acoustic cavity 11 is connected to the rear acoustic cavity 12 is not limited. By way of example, the specific manner in which the front acoustic cavity 11 is connected to the rear acoustic cavity 12 can include, but is not limited to, welding, bonding, and snap connection. The earphone main board 13 and the speaker 14 can be disposed between the front acoustic cavity 11 and the rear acoustic cavity 12. The earphone main board 13 can be a circuit board. The speaker 14 can be a loudspeaker. The earphone main board 13 can be connected to the speaker 14 by wires. The earphone main board 13 and the speaker 14 can be disposed inside the front acoustic cavity 11 and the rear acoustic cavity 12. The front acoustic cavity 11 can be provided with an acoustic outlet. The acoustic outlet can be an opening for transmitting sound. Further, a dust screen can be disposed outside the acoustic outlet.

[0037] In some embodiments, the battery assembly 2 can include a battery front cavity 21 and a battery rear cavity 22. The battery front cavity 21 and the battery rear cavity 22 can be housings for holding a battery. The battery front cavity 21 can be connected to the battery rear cavity 22. The specific manner in which the battery front cavity 21 is connected to the battery rear cavity 22 is not limited. By way of example, the specific manner in which the battery front cavity 21 is connected to the battery rear cavity 22 can include, but is not limited to, welding, bonding, and snap connection. A battery 23 can be disposed between the battery front cavity 21 and the battery rear cavity 22. The battery 23 can be disposed inside the battery front cavity 21 and the battery rear cavity 22.

[0038] In some embodiments, the sound cavity assembly 1 and the battery assembly 2 can be connected by the antenna ear 3. Specifically, the two ends of the antenna ear 3 can be connected to the sound cavity assembly 1 and the battery assembly 2, respectively. Here, the specific manner in which the two ends of the antenna ear 3 are connected to the sound cavity assembly 1 and the battery assembly 2, respectively, is not limited. As an example, the two ends of the antenna ear 3 can be snap-connected to the sound cavity assembly 1 and the battery assembly 2, respectively. The part where the antenna ear 3 is connected to the sound cavity assembly 1 can be provided with an antenna feed point and a ground feed point. The antenna feed point and the ground feed point can be connected to the earphone main board 13 through the pogo pin provided on the earphone main board 13. Specifically, when the antenna ear 3 is connected to the sound cavity assembly 1, the antenna feed point and the ground feed point on the antenna ear 3 are in contact with the pogo pin provided on the earphone main board 13. The antenna ear 3 can transmit RF (RF-Radio Frequency) signals to the earphone main board 13 through the antenna feed point. The ground feed point can be grounded through the earphone main board 13. In practice, the earphone main board 13 can transmit Bluetooth RF signals to the antenna ear 3 through the antenna feed point. The antenna ear 3 can radiate signals in the form of radiation or receive RF signals from mobile phones or other Bluetooth devices to achieve the function of wireless transmission of Bluetooth signals. As an example, the antenna ear 3 can be, but is not limited to, any one of the following: monopole antenna, PIFA (Planar Inverted F-shaped Antenna) antenna, IFA (Inverted-F antenna), inverted L antenna, Loop (loop) antenna, spiral antenna, PCB (Printed Circuit Board) antenna, slot antenna, FICA (folded inverted conformal antenna). The earphone main board 13 and the battery 23 can be connected by the power line 4. Specifically, one end of the power line 4 can be connected to the battery 23. The other end of the power line 4 can be connected to the earphone main board 13. Thus, because the ear handle connecting the sound cavity assembly and the battery assembly realizes the antenna function, the limitation of the antenna size by the earphone cavity is avoided, and thus the signal of the earphone can be enhanced.

[0039] Optionally, the material of the antenna ear 3 can be metal or glass steel. Thus, receiving and transmitting signals through a metal antenna can make the performance of the earphone better, more stable, and transmit farther.

[0040] Further, the outside of the antenna ear 3 can be wrapped by a plastic layer.

[0041] Optionally, the antenna earpiece 3 can be made of nickel-titanium alloy. Therefore, by using nickel-titanium alloy to manufacture the antenna earpiece, it is possible to satisfy the antenna function while giving the antenna earpiece wear-resistant, corrosion-resistant, high-toughness, and high-elasticity properties, thereby improving wearing comfort.

[0042] Furthermore, the curved shape of the aforementioned antenna ear stem conforms to the ergonomics of most people's ears.

[0043] Optionally, the power cord 4 can be located inside the antenna lug 3. This avoids direct contact between the antenna lug 3 and the user's ear, thus improving user comfort. Furthermore, the antenna lug protects the power cord from stretching or tearing, ensuring a stable connection between the power cord and the motherboard and power supply.

[0044] Optionally, at least one charging contact may be provided on the rear cavity 22 of the battery. The charging contact may be a contact for contacting a charging probe to charge the battery. Each of the at least one charging contact may be electrically connected to the battery. Thus, the battery can be charged via the at least one charging contact.

[0045] Optionally, the angle between the axis of the sound outlet and the axis of the speaker 14 can be in the range of 0°-20°.

[0046] Optionally, the angle between the center line of the antenna lug 3 and the axis of the sound hole can be in the range of 100°-160°.

[0047] Optionally, the rear acoustic cavity 12 may be provided with a vent hole. This vent hole can be used to balance the internal pressure and improve sound quality. Thus, the internal pressure can be balanced and sound quality improved through the vent hole.

[0048] Optionally, the aforementioned front acoustic cavity 11 may also be provided with an in-ear detection component and / or a tuning hole. A laser emitter is provided corresponding to the in-ear detection component. The laser emitter can be connected to the aforementioned headphone mainboard 13. Thus, the in-ear detection component can detect whether the headphones are being worn. The tuning hole can improve the sound quality of the played audio.

[0049] Optionally, both the front acoustic cavity 11 and the rear acoustic cavity 12 can be made of ceramic. Since ceramic possesses excellent high-temperature mechanical properties, chemical corrosion resistance, high-temperature oxidation resistance, and wear resistance, these properties can be improved in the front and rear acoustic cavities.

[0050] Optionally, a microphone is provided on the aforementioned headphone motherboard.

[0051] The above various embodiments of the present disclosure have the following beneficial effects: the earphone of the antenna peripheral device of some embodiments of the present disclosure can utilize the ear handle to realize the antenna function, avoids the limitation of the earphone cavity on the size of the antenna, and makes the antenna greatly away from the battery, the loudspeaker and the mainboard, increases the area of the antenna contacting the signal source, thereby enhancing the signal receiving capability and signal stability of the antenna, and further enhancing the signal of the earphone. Specifically, the reason for the weak signal of the earphone is that the battery, the mainboard and the antenna of the earphone are arranged in the same cavity or the connected cavities, the space in the earphone cavity is insufficient, and the size of the antenna that can be arranged in the cavity is small. In addition, since the conductive material has a shielding effect on the signal, the battery, the loudspeaker and the mainboard all include conductive materials, and the battery, the loudspeaker and the mainboard will generate certain electromagnetic interference waves when working, so arranging the antenna, the battery, the loudspeaker or the mainboard in the same cavity will interfere with the signal reception of the antenna. Based on this, the earphone of the antenna peripheral device of some embodiments of the present disclosure includes an acoustic cavity assembly, a battery assembly and an antenna ear handle. The acoustic cavity assembly includes a front acoustic cavity and a rear acoustic cavity. The front acoustic cavity and the rear acoustic cavity are connected. The earphone mainboard and the loudspeaker are arranged between the front acoustic cavity and the rear acoustic cavity. The front acoustic cavity is provided with an acoustic outlet hole. The battery assembly includes a battery front cavity and a battery rear cavity. The battery front cavity and the battery rear cavity are connected. The battery is arranged between the battery front cavity and the battery rear cavity. The acoustic cavity assembly and the battery assembly are connected through the antenna ear handle. The earphone mainboard and the battery are connected through a power supply line. Because the ear handle connecting the acoustic cavity assembly and the battery assembly realizes the antenna function, the limitation of the earphone cavity on the size of the antenna is avoided, the size of the antenna can be appropriately increased, and the signal of the earphone can be enhanced. Therefore, the earphone of the antenna peripheral device of some embodiments of the present disclosure can utilize the ear handle to realize the antenna function, avoids the limitation of the earphone cavity on the size of the antenna, and makes the antenna greatly away from the battery, the loudspeaker and the mainboard, increases the area of the antenna contacting the signal source, thereby enhancing the signal receiving capability and signal stability of the antenna, and further enhancing the signal of the earphone.

[0052] With reference to Figure 3 , a flow 300 of some embodiments of an audio playing method according to the present disclosure is shown, which includes the following steps:

[0053] In step 301, in response to determining that the current time meets the preset working time condition, a historical environmental audio sequence collected by a microphone in a historical time period is acquired.

[0054] In some embodiments, the execution subject of the audio playing method (for example Figure 1The earphone of the antenna peripheral device shown) can acquire a historical ambient audio sequence in a historical time period collected by a microphone in response to determining that the current time meets a preset working time condition. The earphone of the antenna peripheral device can include a sound cavity assembly, a battery assembly, and an antenna ear stem. The sound cavity assembly can include a front sound cavity and a rear sound cavity. The earphone mainboard and a loudspeaker can be arranged between the front sound cavity and the rear sound cavity. A microphone can be arranged on the earphone mainboard. The preset working time condition can be that the execution subject is in a working time period. As an example, the execution subject can be a right earphone. When a user uses a left earphone and a right earphone at the same time, the right earphone and the left earphone can take turns to reduce noise for 30 minutes respectively. The historical time period can be 1 minute before the current time. In practice, the audio collected by the microphone can be stored in a memory included in the earphone mainboard. The execution subject can acquire the historical ambient audio sequence in the historical time period collected by the microphone from the memory.

[0055] In step 302, the antenna ear stem receives the to-be-played audio sent by the associated terminal device.

[0056] In some embodiments, the execution subject can receive the to-be-played audio sent by the associated terminal device through the antenna ear stem. The to-be-played audio can be audio that needs to be played. For example, the to-be-played audio can be a piece of music. The terminal device can be a mobile phone, a computer, or a tablet.

[0057] In step 303, an inverse-phase audio sequence is generated according to the historical ambient audio sequence.

[0058] In some embodiments, the execution subject can generate an inverse-phase audio sequence according to the historical ambient audio sequence. The inverse-phase audio sequence can be an audio sequence that is opposite in phase but the same in amplitude and frequency as the historical ambient audio sequence. As an example, the execution subject can perform phase inversion processing on the historical ambient audio sequence to obtain the inverse-phase audio sequence. Specifically, the execution subject can determine an audio sequence that is opposite in phase but the same in amplitude and frequency as the historical ambient audio sequence as the inverse-phase audio sequence.

[0059] In some optional implementations of some embodiments, according to the historical ambient audio sequence, the execution subject can generate an inverse-phase audio sequence by the following steps:

[0060] First, the decibels of each frame of ambient audio in the ambient audio sequence are determined to obtain a decibel sequence corresponding to the historical ambient audio sequence. Each decibel in the decibel sequence can be sorted in chronological order.

[0061] Secondly, for each decibel in the decibel sequence, the absolute value of the difference between the decibel and the decibel satisfying the preset adjacent condition in the decibel sequence is determined as the decibel change value, and a set of decibel change values is obtained. The preset adjacent condition can be adjacent to the decibel and located after the decibel. As an example, for the first decibel in the decibel sequence, the execution subject can determine the absolute value of the difference between the first decibel and the second decibel as the decibel change value.

[0062] Thirdly, it is determined whether the set of decibel change values includes a decibel change value that does not satisfy the preset decibel change condition. The preset decibel change condition can be that the decibel change value is less than or equal to the preset decibel change threshold. The preset decibel change threshold can be a preset decibel change value.

[0063] Fourthly, in response to determining that the set of decibel change values does not include a decibel change value that does not satisfy the preset decibel change condition, a reverse-phase environmental audio sequence corresponding to the historical environmental audio sequence is determined. In practice, in response to determining that the set of decibel change values does not include a decibel change value that does not satisfy the preset decibel change condition, the execution subject can perform phase inversion processing on the historical environmental audio sequence to obtain a reverse-phase environmental audio sequence. Specifically, the execution subject can determine an audio sequence that is opposite in phase to the historical environmental audio sequence but has the same amplitude and frequency as the reverse-phase environmental audio sequence.

[0064] In the fifth step, a preset audio sequence generation model corresponding to the average decibel is selected from a preset audio sequence generation model set as a target audio sequence generation model according to the average decibel. The preset audio sequence generation model can be a machine learning model pre-trained to take a historical environmental audio sequence as input and predict an audio sequence as output. For example, the preset audio sequence generation model can be a CNN (Convolutional Neural Network). Each preset audio sequence generation model in the preset audio sequence generation model set can be applied to different scenarios. As an example, the execution subject can preset three scenarios. Each scenario corresponds to a decibel range. For example, the decibel range corresponding to a quiet scenario can be (0 decibel, 40 decibel]. The decibel range corresponding to a regular scenario can be (40 decibel, 70 decibel]. The decibel range corresponding to a noisy scenario can be greater than 70 decibels. In practice, first, the execution subject can determine the decibel range in which the average decibel is located. As an example, the average decibel can be 50 decibels, and the decibel range corresponding to the average decibel is (40 decibels, 70 decibels]. Then, according to the determined decibel range, the scenario in which the user is located is determined. For example, the scenario in which the user is located can be a regular scenario. Finally, the execution subject can determine the preset audio sequence generation model corresponding to the scenario in which the user is located in the preset audio sequence generation model set as the target audio sequence generation model.

[0065] In the sixth step, the historical environmental audio sequence is input into the target audio sequence generation model to obtain a predicted audio sequence corresponding to the historical environmental audio sequence.

[0066] In the seventh step, a counter-phase predicted audio sequence corresponding to the predicted audio sequence is determined. In practice, the execution subject can perform phase inversion processing on the predicted audio sequence to obtain a counter-phase predicted audio sequence. Specifically, the execution subject can determine an audio sequence having the same amplitude and frequency but opposite phase to the predicted audio sequence as the counter-phase predicted audio sequence.

[0067] In the eighth step, the counter-phase environmental audio sequence or the counter-phase predicted audio sequence is determined as a counter-phase audio sequence.

[0068] The above-mentioned related content serves as one of the invention points of the present disclosure, thereby solving the technical problem three mentioned in the background art that "related wireless earphones mostly collect a segment of environmental noise, directly simulate inverse sound waves on the basis of a segment of environmental noise, and perform noise cancellation and noise reduction, and through this way of noise reduction, the noise reduction effect is poor in places where the noise changes greatly, resulting in poor user experience". The factors that lead to poor user experience are often as follows: related wireless earphones mostly collect a segment of environmental noise, directly simulate inverse sound waves on the basis of a segment of environmental noise, and perform noise cancellation and noise reduction, and through this way of noise reduction, the noise reduction effect is poor in places where the noise changes greatly. In order to achieve this effect, first, the decibels of each frame of environmental audio in the above-mentioned environmental audio sequence are determined to obtain a decibel sequence corresponding to the above-mentioned historical environmental audio sequence. Then, for each decibel in the above-mentioned decibel sequence, the absolute value of the difference between the above-mentioned decibel and the decibels in the above-mentioned decibel sequence that satisfy a preset adjacent condition is determined as a decibel change value to obtain a set of decibel change values. Wherein, the above-mentioned preset adjacent condition is adjacent to the above-mentioned decibel and located after the above-mentioned decibel. Then, it is determined whether the above-mentioned set of decibel change values includes a decibel change value that does not satisfy a preset decibel change condition. Then, in response to determining that the above-mentioned set of decibel change values does not include a decibel change value that does not satisfy the above-mentioned preset decibel change condition, a reverse environmental audio sequence corresponding to the above-mentioned historical environmental audio sequence is determined. In this way, when the noise changes little, the inverse sound waves can be simulated on the basis of the historical environmental audio sequence to perform noise cancellation and noise reduction. Then, in response to determining that the above-mentioned set of decibel change values includes a decibel change value that does not satisfy the above-mentioned preset decibel change condition, an average decibel of the above-mentioned decibel sequence is determined. Then, according to the above-mentioned set of decibel change values and the above-mentioned average decibel, a preset audio sequence generation model corresponding to the above-mentioned average decibel is selected from a set of preset audio sequence generation models as a target audio sequence generation model. Then, the above-mentioned historical environmental audio sequence is input into the above-mentioned target audio sequence generation model to obtain a predicted audio sequence corresponding to the above-mentioned historical environmental audio sequence. Then, a reverse predicted audio sequence corresponding to the above-mentioned predicted audio sequence is determined. Finally, the above-mentioned reverse environmental audio sequence or the above-mentioned reverse predicted audio sequence is determined as a reverse audio sequence. In this way, when the noise changes greatly, a corresponding preset audio sequence generation model can be selected according to the size of the noise decibel to determine a predicted audio sequence, so that the inverse sound waves can be simulated according to the predicted audio to perform noise cancellation and noise reduction. Because the predicted audio is closer to the actual noise, the noise reduction effect can be improved, and the user experience can be improved.

[0069] Step 304, according to the reverse audio sequence, the noise reduction processing is performed on the to-be-played audio to obtain the noise-reduced audio corresponding to the to-be-played audio.

[0070] In some embodiments, the execution subject can perform noise reduction on the to-be-played audio according to the inverted audio sequence to obtain noise-reduced audio corresponding to the to-be-played audio. In practice, the execution subject can play the audio corresponding to the inverted audio sequence to offset the noise in the environment, thereby achieving noise reduction.

[0071] At step 305, the noise-reduced audio is played through the loudspeaker and sent to the associated counter-earphone through the antenna ear handle for synchronous playing.

[0072] In some embodiments, the execution subject can play the noise-reduced audio through the loudspeaker and send the noise-reduced audio to the associated counter-earphone through the antenna ear handle for synchronous playing. The associated counter-earphone can be an earphone paired with the earphone of the antenna peripheral. In this way, by sending the noise-reduced audio to the counter-earphone instead of performing noise reduction on the counter-earphone side at the same time, the power consumption of the earphone can be reduced, thereby prolonging the battery life of the earphone.

[0073] At step 306, in response to determining that the current time does not satisfy the preset working time condition, the noise-reduced audio sent by the counter-earphone is received.

[0074] In some embodiments, the execution subject can receive the noise-reduced audio sent by the counter-earphone in response to determining that the current time does not satisfy the preset working time condition. It can be understood that, in response to determining that the current time does not satisfy the preset working time condition, the counter-earphone can perform noise reduction on the to-be-played audio to obtain noise-reduced audio. The counter-earphone can send the obtained noise-reduced audio to the execution subject. In practice, in response to the current time not belonging to the time period during which the execution subject performs noise reduction, the execution subject can obtain the noise-reduced audio from the counter-earphone.

[0075] At step 307, the noise-reduced audio is played through the loudspeaker.

[0076] In some embodiments, the execution subject can play the noise-reduced audio through the loudspeaker.

[0077] The above various embodiments of the present disclosure have the following beneficial effects: the audio playing method of some embodiments of the present disclosure can reduce the power consumption of the earphone and prolong the endurance of the earphone. Specifically, the reason for poor endurance of the earphone is that the related wireless earphone simultaneously performs noise reduction processing on the audio in the noise reduction mode. Based on this, the audio playing method of some embodiments of the present disclosure is applied to the earphone of the antenna peripheral device described in the first aspect, wherein the earphone of the antenna peripheral device includes a sound cavity assembly, a battery assembly, and an antenna ear stem. The sound cavity assembly includes a front sound cavity and a rear sound cavity. The earphone mainboard and a loudspeaker are arranged between the front sound cavity and the rear sound cavity. A microphone is arranged on the earphone mainboard. First, in response to determining that the current time meets the preset working time condition, a historical ambient audio sequence in a historical time period collected by the microphone is obtained. In this way, the noise in the environment can be collected. Second, the antenna ear stem receives the to-be-played audio sent by the associated terminal device. Then, according to the historical ambient audio sequence, a reverse audio sequence is generated. In this way, the obtained reverse audio sequence can be used to reduce the noise of the to-be-played audio. After that, the to-be-played audio is processed according to the reverse audio sequence to obtain the noise-reduced audio corresponding to the to-be-played audio. In this way, the noise-reduced to-be-played audio can be obtained. Then, the loudspeaker plays the noise-reduced audio, and the antenna ear stem sends the noise-reduced audio to the opposite earphone for synchronous playing. In this way, by sending the noise-reduced to-be-played audio to the other earphone, the other earphone does not need to perform noise reduction again, thereby reducing the waste of power consumption. Then, in response to determining that the current time does not meet the preset working time condition, the noise-reduced audio sent by the opposite earphone is received. In this way, after a period of time, the other earphone can be used to reduce the noise of the to-be-played audio, and the noise-reduced to-be-played audio can be directly obtained. Finally, the loudspeaker plays the noise-reduced audio. Because the audio playing method can realize that the two earphones take turns to perform noise reduction processing on the audio, and does not need to simultaneously perform noise reduction processing on the audio, the time for noise reduction processing is reduced, thereby reducing the power consumption of the earphone and prolonging the endurance of the earphone. In this way, the audio playing method of some embodiments of the present disclosure can reduce the power consumption of the earphone and prolong the endurance of the earphone.
