The earphone provided in the related art has difficulty in adjusting the audio output gain. However, different users have different wearing habits of earphones and different physiological parameters of the ear (e.g., the distance from the eardrum to the mouth of the ear canal, and the texture of the ear canal). Accordingly, when different users use the earphones with the same audio output gain, some users feel loud, some users feel soft, and the use experience is poor.
Based on the above situation, the embodiments of the present disclosure provide an audio output method and apparatus applied to an earphone, and an earphone, which consider the differences of different users, implement a personalized audio output effect, and optimize user experience.
The audio output method provided by the embodiment of the disclosure is suitable for an earphone, and the earphone is matched with terminal equipment and comprises an ear canal characteristic detection component. Fig. 1 to 4 are flow diagrams illustrating audio output methods according to various exemplary embodiments. As shown in fig. 1, an audio output method provided by an embodiment of the present disclosure includes:
and step S101, responding to the connected signal sent by the terminal equipment, and acquiring the characteristics of the auditory canal through an auditory canal characteristic detection component.
Illustratively, the headset is connected with the terminal device through a data interface, or the headset is connected with the terminal device through a wireless network (e.g., bluetooth, Wifi), and the like. And after the earphone is connected with the terminal equipment, the terminal equipment sends a connected signal to the earphone through a data interface or a wireless network.
In one embodiment, step S101 acquires ear canal characteristics using infrared light. Specifically, the ear canal feature detection assembly includes: infrared transmitter, infrared receiver, and processing chip. Fig. 2 is a flow chart illustrating a method of obtaining a eardrum-to-headphone distance in accordance with an exemplary embodiment. As shown in fig. 2, step S101 includes:
step S1011 emits infrared light into the ear canal.
Infrared light is emitted through the infrared emitting assembly. Optionally, the infrared emitting assembly has an emitting end disposed on an outer surface of the headset. And the transmitting end of the infrared transmitting component is positioned around the sound outlet hole of the earphone. The emitting end of the infrared emitting assembly faces the ear canal of the user when the user wears the headset. In this manner, infrared light emitted by the infrared-emitting component propagates in the ear canal and may be reflected by ear canal structures (e.g., ear canal walls, eardrum, etc.).
Step S1012 receives infrared light reflected from the inside of the ear canal.
Infrared light reflected back by ear canal structures is received by the infrared receiving assembly. Optionally, the infrared receiving assembly continuously receives the infrared light within a set time period (e.g., 1s, 2s, 3s, 4s, 5s, etc.) after the infrared emitting assembly emits the infrared light, so as to receive sufficient infrared light, thereby ensuring detection accuracy.
Further, the infrared receiving component integrates the intensity of the received infrared light within a set time period to obtain infrared light intensity information.
The intensity of the infrared light reflected back by the ear canal structure is related to the distance of the ear canal structure from the earpiece. Specifically, the further away the ear canal structure is from the earpiece, the less intense the infrared light reflected back by the ear canal structure; the closer the ear canal structure is to the earpiece, the stronger the intensity of the infrared light reflected back by the ear canal structure. Also, there are differences in the relative positions of the different structures within the ear canal and the earpiece. For example, the physiological curvature of the ear canal is closer to the earpiece than the eardrum. Therefore, the intensity of the infrared light reflected back through the eardrum can reflect the distance relationship between the ear canal structure, such as the eardrum in the ear canal and the ear canal texture, and the earphone.
Step S1013, ear canal characteristics are acquired according to the intensity of the received infrared light.
The processing chip is connected with the infrared receiving assembly and receives the infrared light intensity information sent by the infrared receiving assembly. Optionally, the processing chip acquires an infrared image in the ear canal according to the infrared light intensity information. Furthermore, the distance from the earphone to the eardrum and the characteristics of the auditory canal such as the texture characteristics of the auditory canal are obtained by analyzing the infrared image in the auditory canal.
In one embodiment, step S101 specifically includes: the ear canal characteristics are acquired after a set period of time (e.g., 5s, 10s, 15s, etc.) in response to a connected signal transmitted by the terminal device.
When the user uses the headset, the headset and the terminal equipment are connected firstly and then worn. For such an application scene, a set time period is used as the buffering time for the user to wear the earphone, so that errors caused by receiving infrared light reflected by other objects in the process of wearing the earphone by the user are avoided. The specific duration of the set time period can be obtained by counting data of different users wearing the earphones.
In one embodiment, step S101 specifically includes: and acquiring the ear canal characteristics according to a set period in response to the connection with the terminal equipment. Illustratively, the infrared emitting components in the headset emit primary infrared light at intervals of 10s, 20s, 30s, etc. And the duration of the interval for emitting the infrared light is longer than the duration of the receiving time period of the infrared receiving component. In this way, after the earphone is connected with the terminal, the earphone periodically acquires the characteristics of the ear canal, and the position change of the earphone and the user is acquired in real time.
And S102, determining audio output gain according to the acquired ear canal characteristics.
The ear canal characteristics such as the distance from the eardrum to the ear canal opening and the ear canal texture are fixed physiological characteristics, and the wearing habit of the earphone of the same user is relatively fixed. In such a case, the distance from the worn ear piece to the eardrum is relatively fixed for the same user, and the position of the ear canal texture to the ear piece is also relatively fixed. The distance from the ear piece to the eardrum and the position of the ear canal texture relative to the ear piece are different for different users based on differences in wearing habits and physiological structures. Therefore, there is a difference in the loss of audio propagating in the ear canal based on the ear canal characteristics of different users, resulting in different sound effects being heard by different users setting the same output configuration earphone output.
The audio output gain is related to the sensitivity, the signal-to-noise ratio and the playing volume of the earphone, and different playing effects can be realized by regulating and controlling the audio output gain of the earphone. In step S102, the ear canal characteristics acquired in step S101 are used as a regulation basis for the audio output gain, so that the determined audio output gain is adapted to the physiological characteristics and wearing habits of the user.
In one embodiment, step S102 determines the audio output gain by the eardrum-to-headphone distance. Fig. 3 is a flowchart illustrating an audio output method according to another exemplary embodiment. As shown in fig. 3, step S102 includes:
step S301, judging whether the distance from the earphone to the eardrum is within the wearing distance range. If yes, go to step S302, otherwise go to step S303.
Optionally, the wearing distance ranges from 2cm to 3.5 cm. 2 cm-3.5 cm is the distance range from the external auditory meatus to the eardrum of an adult. If the judgment result is yes, the earphone is in a wearing state. If not, the earphone is not in a wearing state, for example, the user takes off the earphone in the using process.
If the determination result in step S301 is yes, step S302 is performed. Specifically, the audio output gain is determined according to the pre-stored correspondence between the distance from the eardrum to the earphone and the audio output gain. Optionally, the correspondence between the distance from the earphone to the eardrum and the audio output gain is obtained through sampling and statistics.
If the determination result in step S301 is negative, otherwise, step S303 is executed. Specifically, a gain smaller than a set threshold is used as the audio output gain. When the earphone outputs the audio frequency with the gain smaller than the set threshold value, the volume of the output audio frequency is smaller, and the condition that the user takes off the earphone and sound leakage occurs is avoided. Optionally, in step S303, the audio output gain is set to 0, that is, the earphone is in a mute state.
In one embodiment, step S102 determines the audio output gain by the eardrum-to-earpiece distance and ear canal texture. Fig. 4 is a flowchart illustrating an audio output method according to another exemplary embodiment. As shown in fig. 4, step 102 includes:
step S401, judging whether the distance from the eardrum to the earphone is the prestored distance from the eardrum to the earphone.
Wherein the eardrum-to-earphone distance of at least one earphone common user is pre-stored. Since there may be slight differences in the position where the user wears the headset each time, at least one set of eardrum-to-headset distances is pre-stored, which corresponds to one common user of the headset.
If the determination in step S401 is yes, step S402 is executed. Step S402 is specifically to determine the user identity according to the ear canal texture feature, and use the audio output gain corresponding to the user identity as the audio output gain of the earphone.
If the step S401 determines that the currently detected distance from the eardrum to the earphone is the pre-stored distance, it indicates that the current user may be a frequently-used user of the earphone. To further accurately verify the user identity, the user identity is determined from the ear canal texture features in step S402. The ear canal texture features of different users are different, so that the user identity can be determined by the ear canal texture features. Optionally, the user identity is determined in the common user according to the currently detected ear canal texture feature according to the pre-stored correspondence between the ear canal texture feature and the user identity.
Further, an audio output gain corresponding to the user identity is obtained based on the determined user identity. The audio output gain is a customary headset configuration parameter corresponding to the user identity. In this way, the earphone can output audio with the audio output gain matched with the user identity, so that the user is prevented from manually adjusting the volume, and the user experience is optimized.
If the determination in step S401 is no, step S403 is executed. Step S403 is specifically to determine the audio output gain according to the distance from the eardrum to the earphone and the set rule.
If the step S401 determines that the currently detected distance from the eardrum to the earphone is not the pre-stored distance, it indicates that the current user is not a common user of the earphone. In such a case, the audio output gain may optionally be determined according to a rule that the eardrum-to-headphone distance is inversely related to the audio output gain.
And step S103, outputting the audio according to the determined audio output gain.
Since the audio output gain is determined for different user's headset to eardrum distances. Therefore, in step S103, the audio output gain is used as the default configuration of the earphone to output audio, which is adapted to the current wearing habit of the earphone and the physiological characteristics of the ear canal of the user. Furthermore, the playing effect of the earphone is improved, and the user experience is optimized.
According to the audio output method provided by the embodiment of the disclosure, the distance from the earphone to the eardrum of the user is acquired, and the audio output gain of the earphone is automatically adjusted according to the distance, so that personalized setting for different users is realized. By adopting the mode, the audio playing effect of the earphone adapts to the physiological characteristics and wearing habits of different users, and the user experience is optimized.
Fig. 5 is a flowchart illustrating an audio output method according to another exemplary embodiment. In one embodiment, the method shown in FIG. 5 is based on a modification of the above method after step S302. As shown in fig. 5, the method further includes, after step S302:
step S501, determining the identity of the user according to the distance between the earphone and the eardrum.
Different users have different distances from the headset to the eardrum based on the wearing habits of the headset and the physiological structural characteristics of the ears. Thus, the distance of the headset from the eardrum can be characteristic of different users. Furthermore, the user identities corresponding to different users can be represented by the distance from the earphone to the eardrum.
Optionally, the processor of the headset stores a corresponding relationship between the distance from the headset to the eardrum and the identity of the user in advance. And inquiring the identity of the user according to the corresponding relation through the distance from the current earphone to the eardrum.
As one example, headphones include a left channel component that fits to the left ear, and a right channel component that fits to the right ear. Ear canal characteristic detection components are arranged in the left sound channel component and the right sound channel component. In such a case, the distance of the headset from the eardrum includes: a first distance from the left channel component to the left eardrum, and a second distance from the right channel component to the right eardrum. At this time, step S501 specifically includes: and determining the identity of the user according to the first distance and the second distance. The accuracy of the determined user identity is improved by two parameters, namely the first distance and the second distance.
Step S502, sending the user identity to the terminal equipment so that the terminal equipment can determine the corresponding audio information to be played according to the user identity.
Taking the user identity as the music player account as an example, the terminal device determines the music playlist corresponding to the user identity according to the user identity sent by the earphone, and takes the song in the music playlist corresponding to the user identity as the audio information to be played.
And step S503, receiving the audio information to be played sent by the terminal equipment.
The earphone receives the audio to be played sent by the terminal equipment through a wireless network or a data interface, and then outputs the audio according to the received audio information to be played with the audio output gain determined in the steps S101 to S103.
Further, in the case where the headphone includes a left channel component and a right channel component, it is also noted that: in step S101, ear canal characteristics of the left ear and ear canal characteristics of the right ear are obtained, respectively. In step S102, determining audio output gain of a left sound channel assembly according to the characteristics of the ear canal of the left ear; the right channel assembly audio output gain is determined based on the right ear canal characteristic. In step S103, the left channel component is controlled to output audio with the audio output gain of the left channel component as a default setting, and the right channel component is controlled to output audio with the pinyin output gain of the right channel component as a default setting. That is, the audio output gains of the left and right channel components of the headphones are independently regulated.
