Description

How to automatically switch the working mode of headphones

The present invention relates to an earphone working mode switching method, and in particular to an earphone working mode automatic switching method for earphones.

With the popularity of headphones, people can be seen wearing headphones to listen to music, listen to the radio, or make remote calls in many different situations, such as on the road, in transportation, in stores, or in libraries. In order to adapt to different usage scenarios of headphones, the working modes of headphones have gradually been introduced into Active Noise Cancellation (ANC) mode and Hear Through (HT) mode. For example, when the headset is used in a noisy environment, the user can manually switch the working mode of the headset to the active noise reduction mode to reduce the noise generated by the noisy environment, so that the user can clearly hear the headset transmission. When the use situation of the headset is to communicate or chat with people in person, the user can manually switch the working mode of the headset to the transparent mode to reduce the discomfort of muffled sound during communication or chatting. This allows users to hear themselves and the other party's voices clearly without taking off their headphones.

However, it is known that switching between the active noise reduction mode and the transparency mode of headphones is achieved by manual switching by the user. For example, when a user listening to music on headphones moves from a quiet environment to a noisy environment, in order to hear the music continuously and clearly, the user needs to manually switch the working mode of the headphones to the active noise reduction mode. . In another example, when a user wearing headphones needs to talk to others face to face, he or she needs to manually switch the working mode of the headphones to the transparent mode.

The features, objects and functions of the present invention will be further disclosed below. However, the following descriptions are only examples of the present invention and should not be used to limit the scope of the present invention. That is, any equivalent changes and modifications made in accordance with the patentable scope of the present invention will still remain the gist of the present invention. It does not deviate from the spirit and scope of the present invention, so it should be regarded as a further implementation form of the present invention.

Please refer to FIG. 1 , which is a functional block diagram of an earphone according to an embodiment of the present invention. As shown in FIG. 1 , the earphone 1 of the present invention includes a main body 10 , a memory module 11 , a sound collection module 13 , a processing module 15 and a broadcast module 17 . The memory module 11, the radio module 13 and the broadcast module 17 are electrically connected to the processing module 15, and the memory module 11, the radio module 13, the processing module 15 and the broadcast module 17 can be arranged in the same or different locations. on the circuit board and fixed in the main body 10 . The main body 10 may be in the form of an earplug type, an ear canal type, an earhook type or an earmuff type, and is used to be worn on the ears, but is not limited thereto.

The memory module 11 is used to store multiple sound types and corresponding sound data. The sound data includes parameters such as amplitude, frequency, and waveform, and one sound type corresponds to a set of sound data. Therefore, as long as the sound data is obtained, it can be derived Corresponding sound type and perform subsequent processing.

The radio module 13 is used to receive the environmental sound S1. For the convenience of explanation, the environmental sound S1 is represented by a sine wave, but it is not limited to this. After the sound collection module 13 receives the environmental sound S1, the processing module 15 analyzes the environmental sound S1 into sound data D1, and further derives the corresponding sound data D1 through the sound type and the corresponding sound data D1 stored in the memory module 11. types of sounds. Then, when the sound type is determined and the sound collection module 13 continues to receive the environmental sound S1 for a specific period of time, the processing module 15 will switch the working mode of the earphone 1 from the previous working mode to the active mode according to the sound type. Noise reduction mode or transparency mode.

Specifically, when the sound type is noise sound, the processing module 15 will control the broadcast module 17 to play the inverted environmental sound S2 with the opposite phase to the environmental sound S1. At this time, the working mode of the headset 1 is the active noise reduction mode. , for the user, since the ambient sound S1 entering the ear will offset the inverted ambient sound S2, the user will not hear the ambient sound S1 and achieve the effect of active noise reduction. When the sound type is non-noise sound, the processing module 15 will control the broadcast module 17 to play the in-phase ambient sound S3 with the same phase as the ambient sound S1. At this time, the working mode of the earphone 1 is the transparent mode, and for the user In other words, even if wearing headphones, the user can still hear the same in-phase ambient sound S3 as the ambient sound S1, thereby reducing the dull and uncomfortable feeling.

It can be known from the above description that the earphone 1 of the present invention can determine whether the sound type of the environmental sound S1 received by the sound collection module 13 is noise sound or non-noise sound through the cooperation of the memory module 11 and the processing module 15. And after the sound receiver module 13 continues to receive the ambient sound S1 for a specific period of time, the processor 15 will control the broadcast module 17 to play the anti-phase ambient sound S2 or the in-phase ambient sound S3 to automatically switch the working mode of the earphone 1 .

In other embodiments, in order to achieve better transparency or noise reduction effects, the earphone 1 of the present invention can process directional environmental sounds or noise sounds. For example, after the working mode of the earphone 1 is switched to the transparency mode, when the ambient sound S1 enters the radio module 13 in the first direction, the processing module 15 will analyze that the ambient sound S1 enters the radio module 13 in the first direction. The module 13 and then the processing module 15 will control the broadcast module 17 to also output the in-phase ambient sound S3 with the same phase as the ambient sound S1 in the first direction. In another example, after the working mode of the earphone 1 is switched to the active noise reduction mode, when the noise enters the radio module 13 from the first direction, the processing module 15 will analyze that the ambient sound S1 enters from the first direction. The sound collection module 13 and then the processing module 15 will control the broadcast module 17 to also output the inverted noise sound S2 with the opposite phase to the noise sound in the first direction.

Next, the automatic switching method of various earphone working modes of the earphone 1 of the present invention will be further described. Please refer to Figure 1 and Figure 2 together. FIG. 2 is a flowchart illustrating a method for automatically switching an earphone operating mode according to an embodiment of the present invention. In step S20, the sound collection module 13 receives the environmental sound S1. In step S22, the processing module 15 determines that the environmental sound S1 is a self-voice sound. In step S24, after the sound collection module 13 receives the self-voice sound for a first time, the processing module 15 switches the working mode of the earphone 1 from the previous working mode to the first transparent mode. In step S26, after the sound collection module 13 does not receive the self-voice sound for a second period of time, the processing module 15 switches the working mode of the earphone 1 from the first transparent mode to the previous working mode. It should be noted that the aforementioned previous working mode refers to other working modes except the first transparent mode.

The usage situation of the aforementioned earphone 1 usually occurs when the user wearing the earphone 1 has a face-to-face conversation with others. For example, when a user wearing earphones 1 talks face-to-face with others, the user will emit a speech sound (self-voice sound). After the sound collection module 13 receives the self-voice sound for 1.5 seconds (the first time), the earphones The working mode of 1 is switched to the first transparency mode, so that the user can clearly hear the speech sounds of himself and the other party even while wearing the earphone 1. When the conversation ends and the user stops speaking, and the radio module does not receive his own voice for 10 seconds (second time), the working mode of the headset 1 will be switched to the previous working mode.

Please refer to Figure 1 and Figure 3 together. FIG. 3 is a flowchart illustrating a method for automatically switching an earphone operating mode according to another embodiment of the present invention. In step S30, the sound collection module 13 receives the environmental sound S1. In step S32, the processing module 15 determines that the environmental sound S1 is a danger warning sound. In step S34, after the sound collection module 13 receives the danger warning sound for a third time, the processing module 15 switches the working mode of the headset from the previous working mode to the second transparent mode. It should be noted that the aforementioned previous working mode refers to other working modes except the second transparent mode.

The usage situation of the aforementioned earphone 1 usually occurs in situations that a user wearing the earphone 1 will encounter when moving on the road. For example, when a user wearing earphone 1 is driving on the road and an ambulance appears behind him, since the ambulance will produce a whistle (danger warning sound), the radio module 13 will continue to receive the danger warning sound for 1.5 seconds. After seconds (the third time), the working mode of the headset 1 is switched to the second transparent mode, so the user can clearly hear the siren of the ambulance to increase alertness and take corresponding actions, such as giving way. to allow the ambulance to pass.

In one example, the earphone 1 of this embodiment also has a first active noise reduction mode, a second active noise reduction mode, a third active noise reduction mode, a fourth active noise reduction mode, and a fifth active noise reduction mode. The difference between the above five active noise reduction modes lies in the intensity of noise reduction, or the difference lies in the volume of reversed-phase ambient sound. This embodiment demonstrates that the third active noise reduction mode can have one noise reduction intensity, such as a larger noise reduction intensity, which is mainly suitable for noisy environments or temporary sudden loud sounds. In addition, the fourth active noise reduction mode can have another noise reduction intensity, such as a smaller noise reduction intensity, which is mainly suitable for environments that are quiet in most situations. The first active noise reduction mode and the second active noise reduction mode belong to general noise reduction strengths and can be widely applied to situations other than the above two third and fourth active noise reduction modes. The fifth active noise reduction mode is a noise reduction mode designed to reduce wind noise. In terms of use, the earphone 1 of this embodiment can adapt to environmental sounds and switch to different active noise reduction modes to achieve the effect of switching different noise reduction intensities. Of course, although five active noise reduction modes are described here, they are not limited to this. Those with general knowledge in the relevant technical field can also set the volume range by themselves, thereby distinguishing more active noise reduction modes.

Please refer to Figure 1, Figure 4 and Figure 5 together. FIG. 4 is a flowchart illustrating a method for automatically switching an earphone working mode according to another embodiment of the present invention. FIG. 5 is a flowchart illustrating a method for automatically switching an earphone working mode according to another embodiment of the present invention. In step S40, the sound collection module 13 receives the environmental sound S1. In step S42, the processing module 15 determines that the environmental sound is a first noise sound with a first volume and a first frequency. In step S44, after the sound collection module 13 receives the first noise sound for a fifth time, the processing module 15 switches the working mode of the headset from the previous working mode to the first active noise reduction mode.

In step S50, the sound collection module 13 receives the environmental sound S1. In step S52, the processing module 15 determines that the environmental sound is a second noise sound with a second volume and a second frequency. In step S54, after the sound collection module 13 receives the second noise sound for a sixth time, the processing module 15 switches the working mode of the headset from the previous working mode to the second active noise reduction mode. It should be noted that the previous working mode described in Figure 4 refers to other working modes except the first active noise reduction mode, such as the second active noise reduction mode; the previous working mode described in Figure 5 refers to are other working modes besides the second active noise reduction mode, such as the first active noise reduction mode.

The usage situation of the aforementioned earphone 1 usually occurs when the user wearing the earphone 1 is in a noisy environment. For example, when a user wearing earphones 1 sits on a vehicle (such as a bus), the vehicle will generate driving sounds due to the movement of the vehicle. Assume that the frequency of the driving sounds is defined here as the first frequency. When the user is driving at this time, When the volume of the sound is greater than 57dBA (first volume), the driving sound is the first noise sound. After the radio module 13 receives the first noise sound for 10 seconds (the fifth time), the working mode of the earphone 1 is switched. to the first active noise reduction mode.

In another example, when a user wearing headphones 1 enters a store environment, since the store environment is usually filled with human voices, assuming that the frequency of the human voice is defined as the second frequency, when the volume of the human voice is greater than 57dBA ( second volume), the human voice is the second noise sound. After the radio module 13 receives the second noise sound for 10 seconds (sixth time), the working mode of the headset 1 is switched to the second active noise reduction mode. .

In the above two examples, the frequency of the driving sound is defined as the first frequency, and the frequency of the human voice is defined as the second frequency, but it is not limited to this. In other examples, the frequency of driving sound may also be defined as the second frequency, and the frequency of human voice may be defined as the first frequency.

It can be known from the above examples that the working mode of the earphone 1 can be switched to the corresponding noise reduction mode according to the frequencies of different noises. After the working mode of the earphone 1 is switched to the first active noise reduction mode or the second active noise reduction mode, the volume of the first noise sound or the second noise sound will be reduced, and the user will be able to clearly hear the noise coming from the earphone 1 sound without being disturbed by the first noise sound or the second noise sound.

Please refer to Figure 1 and Figure 6 together. FIG. 6 is a flowchart illustrating a method for automatically switching an earphone working mode according to another embodiment of the present invention. In step S60, the sound collection module 13 receives the environmental sound S1. In step S62, the processing module 15 determines that the environmental sound is a third noise sound with a third volume. In step S64, after the sound collection module 13 receives the third noise sound for a seventh time, the processing module 15 switches the working mode of the headset from the previous working mode to the third active noise reduction mode. It should be noted that the aforementioned previous working mode refers to other working modes except the third active noise reduction mode.

The usage situation of the aforementioned earphone 1 usually occurs when the user wearing the earphone 1 changes from a quiet environment to a noisy environment. For example, when a user wearing headphones 1 walks from the library (quiet environment) to the street (noisy environment), the volume of the ambient sound will gradually change from small to loud during the process. For example, when the volume of the ambient sound S1 is greater than 57dBA (the third volume), the ambient sound at this time can be determined by the processing module 15 as the second noise sound. After the radio module 13 receives the second noise sound for 5 seconds (seventh time), the working mode of the earphone 1 is switched to the second active noise reduction mode. At this time, the volume of the second noise sound will be greatly reduced, and the user will be able to clearly hear the sound from the earphone 1 without being interfered by the second noise sound.

Please refer to Figure 1 and Figure 7 together. FIG. 7 is a flowchart illustrating a method for automatically switching an earphone working mode according to another embodiment of the present invention. In step S70, the sound collection module 13 receives the environmental sound S1. In step S72, the processing module 15 determines that the ambient sound is a fourth noise sound with a fourth volume. In step S74, after the sound collection module 13 receives the fourth noise sound for an eighth time, the processing module 15 switches the working mode of the earphone 1 from the previous working mode to the fourth active noise reduction mode. It should be noted that the aforementioned previous working mode refers to other working modes except the fourth active noise reduction mode.

The usage situation of the aforementioned earphone 1 usually occurs when the user wearing the earphone 1 changes from a noisy environment to a quiet environment. For example, when a user wearing earphones 1 walks from the road (noisy environment) to the library (quiet environment), the volume of the ambient sound will gradually change from high to low in the process. For example, when the volume of the ambient sound is less than 57dBA (the fourth volume), the ambient sound at this time can be determined by the processing module 15 as the fourth noise sound. After the radio module 13 receives the fourth noise sound for 10 seconds (eighth time), the working mode of the earphone 1 is switched to the fourth active noise reduction mode. Compared with the volume of the third noise sound to be reduced in the third active noise reduction mode, the volume of the third noise sound to be reduced in the third active noise reduction mode is smaller.

Taking the above example as an example, walking from the street to the library can be roughly seen as a process of moving from a noisy environment to a normal environment and then to a quiet environment. At this time, the earphone 1 will initially provide a strong noise reduction intensity (the third active noise reduction mode), but if it continues to provide a strong noise reduction intensity in a normal environment and a quiet environment, the user will often feel uncomfortable. Accordingly, when the earphone 1 of this embodiment is moved from a noisy environment to a normal environment, it will reduce some noise reduction intensity and become a widely used first active noise reduction mode (or second active noise reduction mode). . Then, when the earphone 1 moves from a normal environment to a quiet environment, it will further reduce the noise reduction intensity and become the fourth active noise reduction mode corresponding to the quiet environment. In other words, after wearing the earphone 1 of this embodiment, the user can change the noise reduction intensity in a stepwise manner no matter which area he moves to. For example, when switching from the second active noise reduction mode to the first (or second) or fourth active noise reduction mode, the user will not continue to feel the negative pressure caused by strong noise reduction, and can hear clearly The sound comes from earphone 1. That is to say, the earphone 1 of this embodiment can change the noise reduction intensity in a stepwise manner no matter which area it moves to, thereby providing a more comfortable wearing experience.

Please refer to Figure 1 and Figure 8 together. FIG. 8 is a flowchart illustrating a method for automatically switching an earphone working mode according to another embodiment of the present invention. In step S80, the sound collection module 13 receives the environmental sound S1. In step S82, the processing module 15 determines that the ambient sound is wind cutting sound. In step S84, after the sound collection module 13 continues to receive the wind cut sound for the ninth time, the processing module 15 switches the working mode of the earphone 1 from the previous working mode to the fifth active noise reduction mode.

In another example, when the user wearing the earphone 1 encounters strong wind, the strong wind will produce a wind-cutting sound when passing through the sound-collecting module 13 of the earphone 1. The sound-collecting module 13 receives the wind-cutting sound for 1.5 seconds (the ninth time). ), the working mode of the earphone 1 is switched to the fifth active noise reduction mode.

The foregoing embodiments are all aimed at automatic switching methods of the working mode of the earphone 1 when the user wearing the earphone 1 has ambient sound. The following will further explain how the earphone 1 works when the user wearing the earphone 1 does not have ambient sound. Automatic switching method of working mode. After the sound collection module 13 does not receive ambient sound for a fourth period of time, the processing module 15 switches the working mode of the earphone 1 from the previous working mode to the first transparent mode.

The usage situation of the aforementioned earphone 1 usually occurs when the user wearing the earphone 1 is in a quiet environment. For example, when a user wearing earphones 1 is in a library (quiet environment), the library is generally quiet and does not produce ambient sounds. The sound collection module 13 does not receive the ambient sounds S1 for 10 seconds (the fourth time), the working mode of the earphone 1 is switched to the first transparency mode, allowing the user to hear ambient sounds while wearing the earphone 1 without feeling the discomfort of muffled sound.

It should be particularly noted that those with ordinary knowledge in the technical field can understand from the foregoing embodiments that although the headphone working mode of the present invention only mentions the first active noise reduction mode, the second active noise reduction mode, and the third active noise reduction mode, Noise mode, fourth active noise reduction mode, fifth active noise reduction mode, first transparency mode or second transparency mode, but is not limited to this. In addition, the aforementioned switching conditions of various headphone working modes are only for reference and are not limited thereto.

To sum up, the earphones provided by the present invention can automatically switch the earphone working mode to the first active noise reduction mode, the second active noise reduction mode, and the third active noise reduction mode according to the received environmental sound and the duration. mode, the fourth active noise reduction mode, the fifth active noise reduction mode, the first transparency mode or the second transparency mode, so that users do not need to bother to manually switch the working mode of the headset, which is very convenient for users .
