The invention can be applied to intelligent frequency division products with Bluetooth and other functional modules coexisting and different audio output ranges, and can automatically switch between the Bluetooth and other functional modules, including but not limited to Bluetooth and hearing aid, Bluetooth and auxiliary hearing aid, Bluetooth and talkback and other products with Bluetooth audio output function together.
The invention can output the Bluetooth and other audio together by adopting a loudspeaker, and can process audio signals according to the audio frequency range actually required by other functions to output the audio frequency section actually required.
In a first aspect, referring to fig. 1, the present invention provides an intelligent frequency divider, which includes a first analog switch module a, a second analog switch module B, a frequency dividing module C, and a full-band speaker terminal SPK.
The first analog switch module A belongs to a Bluetooth audio control unit. The first analog switch module A is provided with a first main channel A1 and a first auxiliary channel A2; the first analog switch module A is used for receiving Bluetooth signals, and if Bluetooth control signals are contained in the Bluetooth signals, the first main channel A1 is controlled to be closed, so that Bluetooth audio signals in the Bluetooth signals are output to the full-frequency horn end SPK along the first main channel A1. If the Bluetooth signal is detected not to contain the Bluetooth control signal, the first auxiliary channel A2 is controlled to be closed, so that the Bluetooth audio signal in the Bluetooth signal is disconnected from being output.
After the bluetooth function is started, bluetooth signals (bluetooth audio signals and/or bluetooth control signals) are input into the first analog switch module a, and if the bluetooth signals are detected to contain the bluetooth control signals, the first main channel a1 is controlled to be closed, so that the bluetooth audio signals are directly output to the full-frequency loudspeaker end SPK. Otherwise, if the Bluetooth control signal is not detected, the first auxiliary channel A2 is controlled to be closed, and the Bluetooth audio signal output is disconnected.
The second analog switch module B belongs to other functional audio control units. The second analog switch module B is provided with a second main channel B1 and a second auxiliary channel B2; the second analog switch module B is configured to receive other function signals, and if it is detected that other function signals include other function control signals, control the second main channel B1 to be closed, so that other function audio signals in the other function signals are output along the second main channel B1; and if the other function signals are detected not to contain other function control signals, controlling the second auxiliary channel B2 to be closed, and enabling other function audio signals in the other function signals to be disconnected for output.
When other functions (such as hearing aid, talkback and the like) are started, other function signals (other function audio signals and/or other function control signals) are input into the second analog switch module B, and if other function signals are detected to contain other function control signals, the second main channel B1 is controlled to be closed, so that other function audio signals are output to the frequency dividing module. Otherwise, if it is detected that the other function signals do not include other function control signals, the second auxiliary channel B2 is controlled to be closed, and the other function audio signals are disconnected from being output.
By switching two groups of internal analog switches (a first analog switch module A and a second analog switch module B), real-time conversion can be achieved according to the function scene used by the current user. The response time of the closed conversion of the analog switch is very short, and no audio signal loss can be realized in the technical aspect.
The frequency dividing module C is used for dividing the frequency of the audio signals with other functions after the audio signals with other functions are output along the second main channel B1.
The full-frequency horn end SPK is used for receiving the bluetooth audio signal output by the first main channel a1 and other functional audio signals after frequency division by the frequency division module C.
When other functional audio signals are input, audio components interfering with audibility are filtered according to actual functional requirements, and the specific implementation modes of the frequency division module C are as follows:
implementation mode one
Referring to fig. 2, in the present embodiment, the frequency dividing module C includes:
a signal input terminal IN + for receiving other functional audio signals;
the series capacitor C1 is connected with the signal input end IN + IN series and then connected to the full-frequency horn end SPK;
the parallel capacitor C2 is connected with the full-frequency horn end SPK in parallel, and the parallel capacitor C2 is connected with the full-frequency horn end SPK in parallel;
and the grounding end IN-is connected with the parallel capacitor and the full-frequency horn end SPK.
IN this embodiment, the operating characteristic of the capacitor "blocking direct current and alternating current" is utilized, and the first-order frequency division function is realized by using the connection mode of the serial capacitor C1 serial input end (signal input end IN +) and the parallel capacitor C2 parallel output end (full-frequency horn end SPK).
A series capacitor C1 (with a large coupling capacitor) is connected IN series with a signal input end IN +, low-frequency band audio signals are filtered, middle and high-frequency band audio signals pass through, and meanwhile, a parallel capacitor C2 (with a small capacitor) is connected IN parallel with an SPK at a full-frequency horn end, and the high-frequency band audio signals are coupled to the ground. Through the working mode of above two electric capacities, with the low band audio signal and the filtering of high band audio signal among the other function audio signal, make the output of intermediate frequency range audio signal to full frequency loudspeaker end SPK, only keep the useful audio signal of intermediate frequency range vocal part. The filter mode circuit is simple in principle and strong in operability, and the output frequency band can be adjusted according to functions and loudspeaker characteristics.
Second embodiment
Referring to fig. 3, in the present embodiment, the frequency dividing module C includes:
a signal input terminal IN + for receiving other functional audio signals;
the series capacitor C1 is connected with the signal input end IN + IN series and then connected to the full-frequency horn end SPK;
the parallel inductor L1 is connected with the full-frequency horn end SPK in parallel through the parallel inductor L1;
the ground terminal IN-is connected with the shunt inductor L1 and the full-frequency horn terminal SPK.
In the embodiment, a second-order frequency division network scheme is used for realizing frequency division output, namely a series capacitor C1 is connected in series and connected with a parallel inductor L1 in parallel to filter low-frequency-band audio signals. The low-frequency band audio signals influencing the human hearing are filtered by using the working characteristics of capacitance direct current isolation and alternating current isolation and inductance direct current isolation.
The signal input end IN + is connected with a capacitor C1 (a large coupling capacitor) IN series to filter low-frequency band audio signals, so that middle-high frequency audio signals pass through, and meanwhile, the full-frequency horn end SPK is connected with an inductor L1 (a small inductor) IN parallel, and residual low-frequency band audio signals are coupled to the ground by using the characteristic of 'alternating current and direct current' of the inductor. Through the coupling mode of the series capacitor C1 and the parallel inductor L1, low-frequency band audio signals are thoroughly filtered, and only the audio signals with the most concentrated medium-high frequency voice parts are reserved. The filtering mode has strong circuit principle and can thoroughly remove the low-frequency audio signals. The parameters of the components can be adjusted according to the requirements of the user using functions, and high-performance acoustic experience is achieved.
Third embodiment
Referring to fig. 4, in this embodiment, the frequency dividing module C includes:
a signal input terminal IN + for receiving other functional audio signals;
the first series capacitor C1, the first series capacitor C1 is connected with the signal input end IN + IN series;
the second series capacitor C2, the second series capacitor C2 is connected in series with the first series capacitor C1 and then is connected to the full-frequency horn end SPK;
one end of a parallel inductor L1 and one end of a parallel inductor L1 are connected between the first series capacitor C1 and the second series capacitor C2;
and the grounding terminal IN-is connected with the other end of the parallel inductor L1 and the full-frequency horn terminal SPK.
In this embodiment, the first and second order crossover networks are used in combination to filter out the low and high frequency band audio signals. The scheme combines a first-order frequency division scheme and a second-order frequency division scheme, filters low-frequency signals through a front-end second-order network, and filters high-frequency-band audio signals through a rear-end capacitor. The SPK at the full-frequency loudspeaker end only outputs the middle-frequency-band audio signal of the human voice band. The frequency division scheme can adjust the output frequency band of the SPK at the full-frequency loudspeaker end according to the audio requirement of an actual product, so that accurate output control is achieved, and optimal acoustic experience is achieved.
Exemplarily, taking a bluetooth and hearing aid dual-function hearing aid earphone as an example: when the Bluetooth function is output, the intelligent frequency divider directly outputs a complete Bluetooth audio signal after detecting a Bluetooth control signal; when the hearing aid function starts, the intelligent frequency divider detects that the hearing aid function signal opens the back, and the frequency division module is automatic to be opened, gets rid of the audio frequency scope that influences the hearing after the frequency division module with hearing aid audio signal to improve the audio quality, reach and accord with high quality hearing aid effect.
Compared with the prior art, two problems exist when the current Bluetooth and the audio of other functional devices are output together, the first one is that any audio signal processing is not adopted and the audio is directly output by a loudspeaker; however, other functional devices (such as hearing aid, intercom, etc.) only need to output an audio signal of a certain frequency band, and signals of other frequency bands are attenuated, otherwise, the hearing feeling is not clear. The other scheme is that two loudspeakers are used, namely the Bluetooth function output is connected with one loudspeaker, other functions are output to the other loudspeaker, and the power consumption of the real-time normally-opened double loudspeakers is greatly improved.
The intelligent frequency division method device can switch in real time according to different working states, and adjust the output frequency band of the loudspeaker in time according to the functional state of the product, thereby meeting the requirement of optimizing tone quality, reducing power consumption, avoiding the need of arranging two loudspeakers, and saving the volume and cost of the product.
In a second aspect, based on the same inventive concept, the present invention provides an intelligent frequency dividing method, which can be implemented by the above intelligent frequency divider, including:
step 101, receiving a bluetooth signal, and if detecting that the bluetooth signal includes a bluetooth control signal, controlling a first main channel a1 to be closed, so that a bluetooth audio signal in the bluetooth signal is output to a full-frequency horn end SPK along a first main channel a 1; if the Bluetooth signal is detected not to contain the Bluetooth control signal, the first auxiliary channel A2 is controlled to be closed, so that the Bluetooth audio signal in the Bluetooth signal is disconnected from being output.
102, receiving other function signals, and if detecting that the other function signals contain other function control signals, controlling the second main channel B1 to be closed, so that other function audio signals in the other function signals are output along the second main channel B1, subjected to frequency division and output to the full-frequency horn end SPK; and if the other function signals are detected not to contain other function control signals, controlling the second auxiliary channel B2 to be closed, and enabling other function audio signals in the other function signals to be disconnected for output.
In one embodiment, the frequency-divided output to the full-band speaker terminal SPK includes: and filtering low-frequency band audio signals and high-frequency band audio signals in other functional audio signals to enable the middle-frequency band audio signals to be output to the full-frequency loudspeaker end SPK. In this embodiment, the low-band audio signal and the high-band audio signal are filtered, and only the useful audio signal of the mid-frequency human voice part is retained, which can be implemented by the frequency dividing module in the first embodiment and the third embodiment.
In another embodiment, the frequency-divided output to the full-band speaker terminal SPK includes: and filtering low-frequency band audio signals in other functional audio signals, so that the middle and high-frequency band audio signals are output to the full-frequency loudspeaker end SPK. In this embodiment, the low-frequency band audio signals are thoroughly filtered, and only the audio signal with the most concentrated middle-high frequency human voice part is retained, which can be implemented by the frequency dividing module in the second embodiment.
It should be noted that, the above steps 101 and 102 are not limited to a time sequence.

On the contrary, if bluetooth function does not start, only other function chips are at the during operation, only need other function chips to input the intelligent frequency divider with function status information foot this moment, the inside frequency division module of intelligent frequency divider automatic start, through the inside predetermined frequency division circuit of frequency division module (refer to above-mentioned embodiment one to embodiment three), filter sound, in order to reduce the influence to the human acoustic frequency channel, make full frequency loudspeaker end SPK only output the sound of human acoustic frequency channel, in order to reach the input audio frequency that more is close to the reality, realize more clear tone quality and experience.
The output mode of the intelligent frequency divider is increased by using the single loudspeaker, when a music audio signal is played, a Bluetooth control signal is output to the intelligent frequency divider inside the Bluetooth chip, and the intelligent frequency divider is switched to a full-frequency mode and output to the full-frequency-band loudspeaker; when the audio signal of other functions (like the hearing aid, talkback etc.) of broadcast, other function control signals of other function chip internal output give intelligent frequency divider, intelligent frequency divider starts intelligent frequency division, through the inside predetermined frequency division circuit of frequency division module, filter the audio signal of other audio frequency bands, with high-frequency signal output full frequency channel loudspeaker in the voice, make loudspeaker output more accord with user's actual demand, experience with the audio frequency that obtains better.
