To facilitate an understanding of the present disclosure, the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the understanding of the disclosure of the disclosure will be more thorough.

All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description of the present disclosure is for the purpose of describing particular embodiments and is not intended to limit the disclosure. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in Figure 1, it is a block diagram of a frequency-divided modular earphone.

A frequency division modular earphone comprises a speaker device 201 and a frequency division modular audio control device, and the frequency division modular audio control device comprises at least two sets of amplification frequency division modules 100 for performing frequency band processing on the sound source and outputting to the speaker Device 201. The input end of the amplifying frequency dividing module 100 detachably turns on the sound source, and the output end detachably turns on the speaker device 201. The amplification frequency division module 100 includes at least one amplifier unit 101 and at least one frequency divider unit 102; the amplifier unit 101 is configured to perform amplification processing on the input sound source, and the frequency divider unit 102 is configured to perform frequency division processing on the input sound source. The amplification frequency division module 100 is for outputting the amplified and frequency-divided sound source to the speaker device 201.

In this embodiment, the amplifying frequency dividing module 100 is configured to receive a sound source and perform amplification and frequency division processing on the sound source. The sound source can be output by the mobile terminal or the PC end, and the mobile terminal and the PC end can output the sound source through the data line. That is, the above control device can be connected to the mobile terminal or the PC terminal through the data line.

The amplification frequency division module 100 includes an amplifier unit 101 and a frequency divider unit 102.

In one embodiment, the amplification crossover module 100 includes an amplifier unit 101 and a frequency divider unit 102; and/or the amplification frequency division module 100 includes two amplifier units 101 and two frequency divider units 102.

The amplifier unit 101 is for receiving a sound source and performing amplification processing on the sound source. Generally speaking, the noise contained in the sound source and the required sound signal are weak and strong. In order to reduce the subsequent processing error, the sound source needs to be amplified, that is, the required sound signal and noise are simultaneously amplified, so that the subsequent Sound signal processing is more precise.

The frequency divider unit 102 is configured to perform frequency division processing on the sound source after the amplification processing, that is, the sound source is classified according to different frequency bands, and the same frequency band is classified and output.

In this embodiment, the frequency division modular audio control device and the terminal are detachably connected. At the same time, the frequency division modular audio control device and the speaker device 201 are also detachably connected. Therefore, when the frequency band output by the frequency division modular audio control device is fixed, the user can select a frequency division modular audio control device of different output frequency bands to be connected between the terminal and the speaker device 201 according to his own preference. Further, when the user listens to the sound source of different frequencies, the user can select the corresponding frequency-modulated modular audio control device according to the sound source to replace the previous frequency-dividing module, so that the user can select the optimal output frequency when listening to different sound sources. The audio control device can improve the user experience, so that the user can always hear the sound source with good effect.

For example, when the crossover modular audio control device is factory set, a crossover modular audio control device outputs the first frequency band audio, and a frequency division modular audio control device outputs the second band audio, a crossover modular audio. The control device outputs the third band audio. Therefore, in the process of listening to music, the user can select a corresponding frequency-modulated modular audio control device according to the frequency band of the music. After changing the type of music to be listened to, the frequency-modulated modular audio control device of the corresponding frequency band can be selected according to the current music to replace the previous frequency-modulated modular audio control device.

Please refer to Figure 2. Specifically, when two sets of amplification frequency division modules 100 are provided, the two sets of amplification frequency division modules 100 output audio of two frequency bands. Therefore, the two frequency bands can be set to 0-200 Hz and 200 Hz-1000 Hz, 200 Hz-1000 Hz and 1000 Hz-4 KHz, 0-200 Hz and 200 Hz-1000 Hz. Taking 0-200 Hz and 200 Hz-1000 Hz as an example, the frequency divider unit 102 in a set of amplification frequency division modules 100 is used to classify and output the sound signals of 0-200 Hz in the sound source to the speaker device 201. The frequency divider unit 102 in the other set of amplification frequency dividing modules 100 is used to classify and output the sound signals of 200 Hz to 1000 Hz in the sound source to the speaker device 201. Therefore, the audio frequencies output by each speaker device 201 are different, so that the audio of the respective frequency bands do not interfere with each other, and at the same time, the noises that are not in the corresponding frequency bands can be filtered out, so that the output sound of the single speaker device 201 is good. Improve the user experience.

Please refer to Figure 3. Similarly, when three sets of amplification frequency division modules 100 are provided, the frequency division modular audio control apparatus includes three sets of amplification frequency division modules 100; each set of amplification frequency division modules 100 includes an amplifier unit 101 and a frequency divider unit. 102, wherein the first group of amplification frequency division module 100 is configured to output a first frequency band audio after amplifying and frequency dividing the sound source of the first set frequency threshold, wherein the frequency range is 0-200 Hz; The group amplification frequency division module 100 is configured to output a second frequency band audio after the sound source of the second set frequency threshold is amplified and frequency-divided, and the frequency range of the frequency band is 200 Hz-1000 Hz; the third group amplification frequency division module 100 After amplifying and frequency dividing the sound source between the third set frequency threshold, the third frequency band audio is output, and the frequency range of the frequency band is 1000 Hz-4 KHz.

The speaker device 201 includes a first speaker, a second speaker, and a third speaker. The first speaker plays the first band audio, the second speaker plays the second band audio, and the third speaker plays the third band audio. Specifically, the first speaker, the second speaker, and the third speaker may be a woofer, a midrange speaker, and a tweeter, respectively, for playing low frequency sound, intermediate frequency sound, and high frequency sound, respectively. The speaker device 201 is further provided with an audio connection line, wherein the fixed connection end of the audio connection line is fixedly connected to the first speaker, the second speaker and the third speaker, respectively, and the model size and frequency division modularization of the active connection end of the audio connection line The audio source output interfaces of the audio control device are matched to achieve detachable turn-on and audio transmission between each other.

In practical applications, three sets of amplification frequency division module 100 are used to process the sound source, which can meet the requirements of most users on the quality of the sound source, that is, the sound source is divided into high frequency and medium frequency bands respectively, so that the audio effect output by the speaker device 201 is more good.

Please refer to Figure 4. When the audio effect is higher, five sets of amplification frequency division modules 100 may be set, that is, the frequency division modular audio control device includes five sets of amplification frequency division modules 100; each set of amplification frequency division modules 100 includes an amplifier unit 101. And a frequency divider unit 102, wherein the first group of amplification frequency division module 100 is configured to output a first frequency band audio after amplifying and frequency dividing the sound source between the first set frequency threshold, and the frequency range of the frequency band is 0 Hz-80 Hz; the second group of amplification frequency division module 100 is configured to perform amplification and frequency division processing on the sound source with the second set frequency threshold, and output the second frequency band audio, the range of the frequency band is 80 Hz-200 Hz; The group amplification frequency division module 100 is configured to output a third frequency band audio after the sound source of the third set frequency threshold is amplified and frequency-divided, and the frequency range of the frequency band is 80 Hz-200 Hz; the fourth group amplification frequency division module 100 After amplifying and frequency dividing the sound source between the fourth set frequency threshold, the fourth frequency band audio is output, and the frequency range of the frequency band is 200 Hz-1000 Hz; the fifth group of amplification frequency dividing module 100 is used for the first After the source predetermined frequency threshold value, and amplifies the division process, the fifth output frequency audio band is the range 1000Hz-2KHz.

Based on the above embodiment, the frequency range of 0 Hz - 40 Hz may be referred to as an extremely low frequency. There are very few instruments in this band, and only instruments such as double bass, bass bassoon, toba, organ, piano, etc. can reach such a low range. Since this extremely low frequency is not the most beautiful range of the instrument, the addition of the pitch and the overtone is the tone of the instrument.

The frequency range 40Hz-80Hz can be called low frequency. This band has instruments such as bass drum, double bass, cello, bass bassoon, bassoon, bass reel, bass clarinet, Tuba, French and so on. This band is the basis for the thick low frequencies. If the amount of this frequency band is too small, it will lead to the mid-high frequency and high frequency, which makes the sound lose balance and is not durable.

The frequency range of 80Hz-200Hz can be called the low frequency. This band is particularly prone to peaks. This is related to the length, width and height of the small room. In order to remove this annoying peak, most people will absorb this band, so that the ears will not be banged. However, in practical applications, the lower frequency and the upper intermediate frequency may have been recessed with the absorption of the low-frequency, which makes the sound thinner and lacks richness. Instruments in this band include the instruments mentioned in the low band, as well as timpani and bass.

The frequency range of 200Hz-1000Hz can be called the intermediate frequency. This band contains almost all instruments and vocals, so it is the most important frequency band. This mid-range is very important in terms of sound. As long as this frequency is sunken, the performance of the sound is immediately thinner.

The frequency range of 1000Hz-2KHz can be called medium and high frequency. About one-fourth of the violin's higher range is here, the upper limit of the viola, the flute, the clarinet, the high-range of the oboe, the lower half of the piccolo, the cymbal, the triangle, and so on. In fact, the high frequency is easy to identify, as long as the high range of the string group and the high range of the wood tube are medium and high frequency.

The frequency range from 2KHz to 4KHz can be called high frequency. This frequency domain has very few opportunities for instrumental performance. Because most of the instruments except the upper limit of the violin, the piano, and the Piccolo high range, most of the instruments do not appear in this band.

The frequency range from 4KHz to 20KHz can be extremely high frequency. Extremely high frequencies accommodate the overtones of instruments and vocals. In general, the overtones of musical instruments are mostly the higher the energy.

The amount of sense in each frequency band does not mean that the equipment is really good or bad. It is important to match the amount of equipment between the devices. Therefore, it is used to select corresponding frequency bands according to their own range preferences for combination.

In one embodiment, the frequency division modular audio control device further includes a frequency control module for connecting the frequency divider unit 102, and the frequency control module is for adjusting the frequency band range output by the frequency divider unit 102.

Thus, the range of frequency bands can be adjusted in conjunction with the user's preference for music. For example, when the user does not like audio with a frequency range of 80 Hz to 200 Hz, the frequency division of this frequency band may not be directly set. When the user needs to segment the audio of each frequency band when listening to the symphony, the corresponding amplifier unit 101 and the frequency divider unit 102 can be sequentially arranged from low to high to perform audio frequency band processing, so that the audio signals of the respective frequency bands are mutually Do not interfere. Specifically, multiple frequency bands such as 0 Hz-40 Hz, 40 Hz-80 Hz, 80 Hz-200 Hz, 200 Hz-1000 Hz, 1000 Hz-2 KHz, 2 KHz-4 KHz, and 4 KHz-20 KHz may be separately set.

Please refer to Figure 5. In a specific setting, seven sets of amplifier units 101 and seven-segment frequency unit 102 may be provided in a set of amplification frequency division modules 100. A group of amplifier units 101 and a group of frequency unit 102 are outputted with 0 Hz - 40 Hz audio, a group of amplifier units 101 and a group of frequency unit 102 output 40 Hz - 80 Hz audio, a set of amplifier units 101 and a component The frequency unit 102 outputs audio of 80 Hz to 200 Hz, a group of amplifier units 101 and a group of frequency unit 102 outputs audio of 200 Hz to 1000 Hz, and a group of amplifier units 101 and a group of frequency unit 102 outputs audio of 1000 Hz to 2 kHz. A group of amplifier units 101 and a group of frequency unit 102 output audio of 2 kHz to 4 kHz, and a group of amplifier units 101 and a group of frequency unit 102 output audio of 4 kHz to 20 kHz. The audio of these seven frequency bands can be directly output to one speaker device 201, or can be output to seven speaker devices 201, respectively.

Please refer to Figure 6. Of course, seven sets of amplification frequency division modules 100 may be separately provided, and each group of amplification frequency division modules 100 is provided with only one set of amplifier unit 101 and one frequency component unit 102, so that seven sets of amplification frequency division modules 100 respectively output seven. The audio of the frequency bands is supplied to one speaker device 201 or separately to the seven speaker devices 201.

The frequency control module can set the frequency band adjustment range according to the user's requirements. Generally, the frequency control module can adjust the full frequency band (0 Hz-20 KHz), that is, the user can separately control the audio frequency band range output by each group of the amplification frequency division module 100 through the frequency control module. Of course, in order to enable all users to adjust the optimal sound effect, the recommended frequency range will be preset, such as 0Hz-40Hz, 40Hz-80Hz, 80Hz-200Hz, 200Hz-1000Hz, 1000Hz-2KHz, 2KHz-4KHz and 4KHz- The frequency range of 20KHz and the like, and the corresponding frequency range is recommended according to the user's music type preference.

For example, when users prefer to listen to instruments such as Bassoon, Tuba, organ, piano, etc., it is recommended to adjust the output frequency range to 0Hz-80Hz and 200Hz-1000Hz. Users prefer to listen to viola, flute, clarinet, oboe, piccolo, cymbal, triangle iron and other musical instruments, it is recommended to adjust the output frequency range to 200Hz-1000Hz and 1000Hz-2KHz. Of course, users can also choose the range of bands that best suits their needs based on the output sound.

In one embodiment, the frequency division modular audio control device is provided with three sets of amplification frequency division modules 100, and each group of amplification frequency division modules 100 is provided with a set of amplifier units 101 and a group of frequency unit 102. The frequency band range output by each group of the amplification frequency division module 100 is adjusted by the frequency control module, or the frequency band range output by each group of the amplification frequency division module 100 is set in advance, and the three frequency bands of high, medium and low are preferentially set. Each set of the amplification frequency dividing module 100 is correspondingly connected to at least one speaker device 201, so that the sound effects received by each of the speaker devices 201 are different, and the user can select the corresponding speaker device 201 to listen to the audio according to his or her preference. At the same time, if the user does not like the currently output sound effect, the frequency control module can be used to adjust the frequency band range output by the amplification frequency dividing module 100 until the desired sound effect is output.

Similarly, how many sets of amplification frequency division modules 100 are provided by the frequency division modular audio control device, and how many sets of amplifier units 101 and frequency divider units 102 are set in the amplification frequency division module 100 can be determined according to user requirements. The control manner is the same as the above embodiment, and details are not described herein again.

Please refer to Figure 7. The frequency division modular audio control device includes a sound source input interface 103 and a sound source output interface 104.

Since the sound source output interface 104 is connected to the speaker device 201, there are a plurality of types of the sound source output interface 104, and it is possible to connect various types of headphones and small sounds on the market.

Specifically, the input end of the audio source input interface 103 detachably turns on the sound source, and the output end fixedly turns on the amplification frequency dividing module 100. The audio source input interface 103 includes at least one of a USB interface, a Type C interface, a Micro USB interface, and a Lightning interface.

Based on the above embodiment, the processing of the sound source may be performed by first performing amplification, and then dividing the amplified sound source into frequency division processing, or performing frequency division first, and then performing amplification processing on the frequency-divided sound source. Of course, the preferred method is that the sound source is first amplified, and then the amplified sound source is subjected to frequency division processing. Since the sound source is amplified, the frequency division result is more accurate.
