Description

Technical Field

[0001] The invention relates to an electronic device and an equalizer adjustment method thereof, and in particular to an electronic device capable of adjusting volume and an equalizer adjustment method thereof. Background Art

[0002] "Equalizer (EQ)" is a tool for adjusting sound, which can adjust the gain value of each frequency band. In other words, the gain value of the sound (or audio file) at different frequencies can be adjusted to change the auditory effect produced by the output sound. For example, the blasting sound presented by heavy bass is more shocking and realistic. Therefore, the current equalizer is mainly used to adjust the output sound effect. Most existing computers also store equalizer applications for users to use for entertainment when listening to music.

[0003] Regarding the gain value setting of the equalizer, the user usually adjusts the gain value of a frequency individually, or there are multiple built-in modes, so that the user can directly select different modes to adjust the gain values ​​of multiple frequencies at one time, which can be used as entertainment for users when listening to music. Generally speaking, users have different hearing levels for different frequencies, so they may increase or decrease the gain values ​​of certain frequencies to achieve the best hearing effect. However, when adjusting the volume, all frequencies are adjusted louder or softer at the same time, without considering the hearing effect, so the frequencies whose gain values ​​have been adjusted may have problems of being too loud or too soft, so the user has to adjust the gain values ​​again. So it will be very troublesome for users.

[0004] Therefore, it is necessary to invent a new electronic device and an equalizer adjustment method thereof to solve the deficiencies of the prior art. Summary of the invention

[0005] The main purpose of the present invention is to provide an equalizer adjustment method, which can be adjusted according to the volume.

[0006] Another main object of the present invention is to provide an electronic device used in the above method.

[0007] To achieve the above-mentioned purpose, the electronic device of the present invention includes an equalizer, a gain value setting module, a storage module and an equalizer adjustment module. The gain value setting module is used to set a volume gain value list, and the volume gain value list includes multiple volume values, which are respectively the first volume value to the Nth volume value, and the volume represented by the first volume value to the Nth volume value increases gradually, and each of these volume values ​​includes a set of correction parameters, and the set of correction parameters includes multiple compensation gain values ​​to correspond to multiple target frequencies respectively. The storage module is electrically connected to the gain value setting module and is used to store the volume gain value list. The equalizer adjustment module includes a volume detection unit, a parameter search unit and a parameter setting unit. The volume detection unit is used to obtain a volume signal. The parameter search unit obtains the corresponding set of correction parameters based on the volume signal. The parameter setting unit adjusts the gain value setting of the equalizer for sound at different frequencies according to the set of correction parameters.

[0022] In order to better understand the technical content of the present invention, preferred specific embodiments are described below.

[0023] Please refer to the following Figure 1 It is a schematic diagram of the structure of the electronic device of the present invention.

[0024] In this embodiment of the present invention, the electronic device 1 can be, for example, but not limited to, a notebook computer, a tablet computer, a smart phone, or other electronic devices with computing and processing functions. For example, a sound playback device (speaker) with a central processing unit or other processor can also be used as the electronic device 1 of this embodiment. The electronic device 1 includes an equalizer 11, a gain value setting module 20, a storage module 30, and an equalizer adjustment module 40. The equalizer 11 is arranged in the audio processing module 10. Specifically, the audio processing module 10 can store the software of the equalizer 11, or the firmware of the equalizer 11, or a combination thereof, so that the equalizer 11 is arranged in the audio processing module 10. By adjusting the gain value setting of the equalizer 11, the gain value of the audio processing module 10 output sound at different frequencies can be adjusted. For example, by raising the gain value of 100 Hz (specified frequency) to 10dB, the volume of the output sound at 100 Hz can be increased by 10dB. Since the equalizer 11 is a common sound output adjustment tool, its structure and principle are already familiar to those with ordinary knowledge in the field, so it is not repeated here.

[0025] The gain value setting module 20 is used to set the volume gain value list 31 stored in the storage module 30. The volume gain value list 31 can be a default gain value of the gain value setting module 20, or it can be set or adjusted by the user using the gain value setting module 20. The volume gain value list 31 may include multiple volume values, respectively a first volume value to an Nth volume value, and the volume represented by the first volume value to the Nth volume value gradually increases. Each of these volume values ​​includes a set of correction parameters, and the set of correction parameters includes multiple compensation gain values ​​to correspond to multiple target frequencies respectively. When the volume is smaller, the gain value setting module 20 will increase the volume of low-frequency sounds and reduce the volume of high-frequency sounds. As shown in the table below:

[0026]

[0027]

[0028] The volume gain value list 31 includes volume values ​​from the first volume value to the Nth volume value from small to large, for example, directly represented by the volume scale 0 to 10 of the electronic device 1, the volume scale 0 is the smallest sound, that is, the first volume value, and the volume scale 10 is the largest sound, that is, the Nth volume value. Therefore, in this embodiment, the first volume value to the Nth volume value can respectively represent 11 different volumes of the electronic device 1, and each volume value and the frequency 100Hz, 1KHz, 10KHz have corresponding compensation gain values. It can be seen from the volume gain value list 31 that the compensation gain values ​​are between -10 and 10, so it is possible to increase or decrease the volume of a certain frequency. When the target frequencies are less than or equal to 100Hz, the compensation gain values ​​corresponding to the target frequencies are between 0 and 10. When the target frequencies are greater than or equal to 10KHz, the compensation gain values ​​will be between -10 and 0, and the compensation gain values ​​of the target frequency of 1KHz will not be adjusted. However, it should be noted that the compensation gain values ​​in the above volume gain value list 31 are only for illustration, and the present invention is not limited to adjusting only the frequencies 100Hz, 1KHz, and 10KHz, and the target frequency less than 100Hz or the target frequency greater than 10KHz can also be adjusted synchronously, and the present invention is not limited to this. When setting the volume gain value list 31, only certain volume values ​​can be set, for example, only the compensation gain values ​​of the frequencies of the maximum volume value, the minimum volume value, and the intermediate volume value are set, and the compensation gain values ​​of the remaining volume values ​​are calculated by interpolation.

[0029] The storage module 30 can be a fixed or removable non-transient computer-readable storage medium, including but not limited to random access memory (RAM), read-only memory (ROM), flash memory, optical disk, or other similar components, or a combination of the above components, or using analog circuit design and other methods. The storage module 30 stores the volume gain value list 31 set by the gain value setting module 20. The equalizer adjustment module 40 is electrically connected to the storage module 30 and the equalizer 11. The equalizer adjustment module 40 includes a volume detection unit 41, a parameter search unit 42 and a parameter setting unit 43. The volume detection unit 41 is used to obtain the volume signal of the electronic device 1. In one embodiment of the present invention, the volume detection unit 41 directly detects a current volume scale of the electronic device 1 to obtain the volume signal, but the present invention is not limited to this.

[0030] The parameter search unit 42 reads the volume gain value list 31 according to the volume signal to obtain the corresponding set of correction parameters. Finally, the parameter setting unit 43 is used to adjust the gain value settings of the equalizer 11 at different frequencies according to the set of correction parameters obtained by the parameter search unit 42.

[0031] It should be noted that the modules of the electronic device 1 can be constructed by hardware devices, software programs combined with hardware devices, firmware combined with hardware devices, etc. For example, a computer program product can be stored in a computer-readable medium, read and executed to achieve the various functions of the present invention, but the present invention is not limited to the above-mentioned methods. In addition, the present embodiment only illustrates the preferred embodiment of the present invention, and in order to avoid redundancy, all possible variations and combinations are not described in detail. However, it should be understood by those of ordinary skill in the art that the above-mentioned modules or components may not all be necessary. And in order to implement the present invention, other more detailed existing modules or components may also be included. Each module or component may be omitted or modified as needed, and there may not be other modules or components between any two modules.

[0032] Please refer to Figure 2 It should be noted that although the equalizer adjustment method of the present invention is described below using the above-mentioned electronic device 1 as an example, the equalizer adjustment method of the present invention is not limited to the electronic device 1 with the same structure as the above-mentioned one.

[0033] First, step 201 is performed: a volume gain value list is set by the gain value setting module.

[0034] First, the gain value setting module 20 is used to set the volume gain value list 31 stored in the storage module 30. The volume gain value list 31 can be the default gain value of the electronic device 1, or can be set or adjusted by the user using the gain value setting module 20, but the present invention is not limited thereto. The volume gain value list 31 includes a plurality of volume values, which are respectively a first volume value to an Nth volume value, and the volume represented by the first volume value to the Nth volume segment increases gradually, and each of the volume segments includes a set of correction parameters, and the set of correction parameters includes a plurality of compensation gain values ​​to correspond to a plurality of target frequencies respectively.

[0035] Next, step 202 is performed: storing the volume gain value list in the storage module.

[0036] Next, the volume gain value list 31 set by the gain value setting module 20 is stored in the storage module 30 .

[0037] Go to step 203: obtain a volume signal.

[0038] Then the volume detection unit 41 is used to obtain the volume signal of the electronic device 1. In one embodiment of the present invention, the volume detection unit 41 directly detects a current volume scale of the electronic device 1 to obtain the volume signal, but the present invention is not limited thereto.

[0039] Then proceed to step 204: read the volume gain value list according to the volume signal to obtain the corresponding set of correction parameters.

[0040] The parameter search unit 42 is used to read the volume gain value list 31 according to the volume signal to obtain the corresponding set of correction parameters according to the volume signal.

[0041] Finally, step 205 is performed: according to the set of correction parameters, the gain value setting of the equalizer at different frequencies of the sound is adjusted by the equalizer adjustment module.

[0042] Finally, the parameter setting unit 43 is used to adjust the gain value setting of the equalizer 11 at different frequencies of the sound according to the set of correction parameters obtained by the parameter search unit 42.

[0043] It should be noted here that the equalizer adjustment method of the present invention is not limited to the above-mentioned order of steps, and the above-mentioned order of steps may also be changed as long as the purpose of the present invention can be achieved.

[0044] From the above description, it can be seen that according to the above implementation, the electronic device 1 can know how to adjust the setting of the equalizer 11 according to the current volume, so when the electronic device 1 adjusts the volume, the equalizer 11 will also change the gain value of each frequency band at the same time.

[0045] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
