Description

Technical Field

[0001] The embodiments of the present invention relate to the field of bone conduction technology, and in particular to a method and device for adaptively controlling the amplitude of a bone conduction speaker based on ambient noise. Background Art

[0002] Bone conduction is the transmission of sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, and auditory center. However, although the bone conduction method can prevent the eardrum from being affected by sound wave vibrations, the disadvantage of bone transmission is obvious compared to the traditional method of sound transmission to the auditory nerve through the ear canal. In the process of sound transmission, the skull transmits sound because the bone density is greater than the sound, so the loss of sound wave energy is also greater. This leads to obvious interference with the effective sound energy finally received by the auditory center once noise appears in the outside world. In addition, in some special occasions, such as when a driver drives a car, when it is night or driving into a remote area, the environmental noise is greatly reduced, and it is considered that it is quite inconvenient to adjust the sound wave energy of the bone conduction headset, which may cause serious accidents such as car accidents in extreme cases. Therefore, the development of a method and device for adaptive amplitude control of a bone conduction speaker based on environmental noise can effectively overcome the defects in the above-mentioned related technologies, which has become a technical problem that needs to be solved urgently in the industry.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In addition, the technical features in the various embodiments or single embodiments provided by the present invention can be arbitrarily combined with each other to form a feasible technical solution. This combination is not subject to the constraints of the sequence of steps and / or the structural composition mode, but must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0018] The embodiment of the present invention provides a method for adaptively controlling the amplitude of a bone conduction speaker based on ambient noise, see Figure 1 , the method includes: when the panel of the bone conduction speaker vibrates, the detected ambient noise intensity is compared with the noise intensity threshold range; if the ambient noise intensity falls outside the noise intensity threshold range, the amplitude of the bone conduction speaker is controlled according to the difference between the ambient noise intensity and the upper limit or lower limit of the noise intensity threshold range, to ensure that the amplitude of the bone conduction speaker after control is adapted to the ambient noise intensity; if the ambient noise intensity falls within the noise intensity threshold range, the current amplitude of the bone conduction speaker is kept unchanged. Specifically, the noise intensity threshold range is 800 Hz to 7000 Hz (i.e. is 800 Hz, is 7000 Hz), and the specific intermediate value can be 1000 Hz, 1500 Hz, 3000 Hz or 5000 Hz.

[0019] Based on the content of the above method embodiment, as an optional embodiment, the method for adaptively controlling the amplitude of a bone conduction speaker based on ambient noise provided in the embodiment of the present invention controls the amplitude of the bone conduction speaker according to the difference between the ambient noise intensity and the upper limit or lower limit of the noise intensity threshold range to ensure that the amplitude of the bone conduction speaker after control is adapted to the ambient noise intensity, including: if the first difference between the lower limit of the noise intensity threshold range and the ambient noise intensity is positive, determining that the first gain of the bone conduction speaker is a negative value, and the first amplitude of the bone conduction speaker adjusted by the first gain is within the first amplitude threshold range.

[0020] Specifically, if the first difference between the lower limit of the noise intensity threshold range and the ambient noise intensity is positive, it means that the ambient noise has reached a level where it has no effect, such as in a late night environment, when the noise is basically zero. In this way, the amplitude of the bone conduction speaker can be adjusted to a smaller level to adapt to the quieter surrounding environment. The user's auditory center will not feel that the volume of the effective sound received is too loud, nor will the excessive volume of the bone conduction headphones cause noise pollution to the surrounding environment.

[0021] Based on the content of the above method embodiment, as an optional embodiment, the method for adaptively controlling the amplitude of a bone conduction speaker based on ambient noise provided in the embodiment of the present invention, wherein the first amplitude of the bone conduction speaker adjusted by the first gain is within the first amplitude threshold range, comprises: in, is the original amplitude of the bone conduction speaker; is the first amplitude; is the first gain; is the lower limit of the noise intensity threshold range; is the lower limit value of the first amplitude threshold range; is the upper limit value of the first amplitude threshold range; is the first difference; is the ambient noise intensity.

[0022] Specifically, We can take 100 Hz, It can be 600 Hz, and between the two, it can also be 200 Hz, 400 Hz, 450 Hz or 500 Hz.

[0023] Based on the content of the above method embodiment, as an optional embodiment, the method for adaptive amplitude control of a bone conduction speaker based on ambient noise provided in the embodiment of the present invention controls the amplitude of the bone conduction speaker according to the difference between the ambient noise intensity and the upper limit or lower limit of the noise intensity threshold range to ensure that the amplitude of the bone conduction speaker after control is adapted to the ambient noise intensity, and also includes: if the second difference between the ambient noise intensity and the upper limit of the noise intensity threshold range is positive, and the second difference is less than a predetermined threshold, determining that the second gain of the bone conduction speaker is positive, and the second amplitude of the bone conduction speaker adjusted by the second gain is within the second amplitude threshold range.

[0024] Specifically, if the second difference between the ambient noise intensity and the upper limit of the noise intensity threshold range is positive, and the second difference is less than the predetermined threshold, it means that the ambient noise has reached a relatively large level, which has affected the user's reception of the sound transmitted by the bone conduction headset, but the interference has not reached the point where the sound of the bone conduction headset is completely disrupted to the user's auditory central nerve. In this way, the amplitude of the bone conduction speaker can be adjusted to a relatively large level to reduce the interference of the surrounding environmental noise on the sound transmitted by the bone conduction headset. For example, when a bus driver is driving and there are many people on the bus, the ambient noise is relatively noisy. At this time, appropriately increasing the amplitude of the bone conduction speaker can ensure that the user's auditory center receives clear sound, thereby continuing to ensure that the user can normally receive the sound emitted by the bone conduction headset.

[0025] Based on the content of the above method embodiment, as an optional embodiment, the method for adaptively controlling the amplitude of a bone conduction speaker based on environmental noise provided in the embodiment of the present invention, wherein the second amplitude of the bone conduction speaker adjusted by the second gain is within the second amplitude threshold range, includes: in, is the second amplitude; is the second gain; is the upper limit of the noise intensity threshold range; is the lower limit value of the second amplitude threshold range; is the upper limit value of the second amplitude threshold range; is the second difference; L is the predetermined threshold.

[0026] Specifically, L can be 1000 Hz, 2000 Hz, 3000 Hz or 4000 Hz; You can take 9000 Hz, It can be 15000 Hz, and the intermediate value between the two can be 10000 Hz, 11000 Hz or 12000 Hz.

[0027] Based on the content of the above method embodiment, as an optional embodiment, the method for adaptive amplitude control of a bone conduction speaker based on ambient noise provided in the embodiment of the present invention controls the amplitude of the bone conduction speaker according to the difference between the ambient noise intensity and the upper limit or lower limit of the noise intensity threshold range to ensure that the amplitude of the bone conduction speaker after control is adapted to the ambient noise intensity, and also includes: if the third difference between the ambient noise intensity and the upper limit of the noise intensity threshold range is positive, and the third difference is greater than a predetermined threshold, determining that the third gain of the bone conduction speaker is negative, and the third amplitude of the bone conduction speaker adjusted by the third gain is zero.

[0028] Specifically, if the third difference between the ambient noise intensity and the upper limit of the noise intensity threshold range is positive, and the third difference is greater than the predetermined threshold, it means that the ambient noise has reached a very high level, which not only affects the user's reception of the sound transmitted by the bone conduction headset, but also the interference has reached the point where the sound of the bone conduction headset is completely disrupted from being transmitted to the user's auditory central nervous system. In this way, if the amplitude of the bone conduction speaker is increased, it will only add more noise to the user, so the bone conduction speaker should be completely turned off to reduce noise interference. For example, when a user arrives at an extremely noisy factory production workshop, the ambient noise is extremely noisy, and some specific workshops have to wear earmuffs to prevent noise from hurting the ears. At this time, the sound emitted by the bone conduction headset should be stopped to avoid meaningless sound output.

[0029] Based on the content of the above method embodiment, as an optional embodiment, the method for adaptively controlling the amplitude of a bone conduction speaker based on ambient noise provided in the embodiment of the present invention, wherein the third amplitude of the bone conduction speaker adjusted by the third gain is zero, comprises: in, is the third amplitude; is the third gain; The third difference.

[0030] Specifically, L can be 7000 Hz, 8000 Hz, 10000 Hz or 12000 Hz.

[0031] The method for adaptively controlling the amplitude of a bone conduction speaker based on ambient noise provided in an embodiment of the present invention sets a noise intensity threshold range, compares the detected ambient noise intensity with the noise intensity threshold range, and adjusts and controls the amplitude of the bone conduction speaker according to the comparison result, thereby ensuring that the amplitude of the bone conduction speaker automatically adapts to the current environment, which not only ensures the sound transmission efficiency of the bone conduction headset, but also simplifies the use mode of the bone conduction headset and improves the user experience.

[0032] The implementation basis of each embodiment of the present invention is to implement programmed processing through a device with a processor function. Therefore, in engineering practice, the technical solutions and functions of each embodiment of the present invention can be encapsulated into various modules. Based on this reality, on the basis of the above embodiments, an embodiment of the present invention provides a bone conduction speaker amplitude adaptive control device based on environmental noise, which is used to execute the bone conduction speaker amplitude adaptive control method based on environmental noise in the above method embodiment.

[0033] The embodiment of the present invention provides a bone conduction speaker amplitude adaptive control device based on environmental noise, using Figure 2 By setting the noise intensity threshold range and comparing the detected ambient noise intensity with the noise intensity threshold range, the amplitude of the bone conduction speaker is adjusted and controlled according to the comparison result, which can ensure that the amplitude of the bone conduction speaker automatically adapts to the current environment, which not only ensures the sound transmission efficiency of the bone conduction headset, but also simplifies the use mode of the bone conduction headset and improves the user experience.
