BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 A flowchart of a communication method for realizing a private call of the present invention; DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Currently, the call process is that the headset receives the voice of the mobile phone, and the user listens to the sound through the headset; the sound of the caller's speech is collected by the headset and then transmitted to the mobile phone to complete the call. However, in this process, the speaker's voice is completely exposed to the surrounding environment and cannot be protected privately.

[0019] Currently, the call process is that the headset receives the voice of the mobile phone, and the user listens to the sound through the headset; the sound of the caller's speech is collected by the headset and then transmitted to the mobile phone to complete the call. However, in this process, the speaker's voice is completely exposed to the surrounding environment and cannot be protected privately.

[0020] In view of the above technical problems, this embodiment provides a communication method for realizing a private call, comprising the steps of: S1: The wireless silencer pre-processes the collected voice to improve the voice quality; S2: The headset and the wireless silencer establish a communication connection; S3: The headset receives the voice data sent by the wireless silencer; S4: The microphone of the headset is turned off and the headset switches to audio output mode; The wireless muffler is worn at the mouth of the speaker to collect the voice emitted by the speaker and send the first audio information obtained by converting the voice to the earphone; the earphone forwards the first audio information to the communication device, which can be a mobile phone or other devices that can implement wireless communication functions. The earphone receives the second audio information from the communication device and converts it into sound to be transmitted to the human ear.

[0021] During a call, the voice of the user wearing the wireless muffler is collected by the wireless muffler and then sent to the earphone, and then forwarded by the earphone to the phone and transmitted to the other party on the call through the phone.

[0022] The voice of the other party is transmitted to the earphone through the phone and then to the ear of the user wearing the wireless muffler through the earphone, completing the call process.

[0023] The wireless muffler can be worn at the mouth of the user. A microphone is provided inside the wireless muffler, which can collect voice when the wearer speaks. The wireless muffler adopts sound absorption and sound insulation treatment to shield the sound emitted by the speaker and prevent it from spreading to the surrounding environment, realizing private calls. The wireless muffler is prior art and will not be introduced in detail here.

[0024] The preprocessing of the voice collected by the wireless muffler includes noise reduction processing on the collected voice. Specifically: The wireless muffler collects voice through a built-in noise reduction microphone. The noise reduction microphone has the function of reducing noise by itself and is prior art. The collected voice is subjected to the first noise reduction processing by the noise reduction microphone to reduce the noise component in the collected voice.

[0025] After that, the wireless muffler performs a second noise reduction processing on the voice through a preset noise reduction algorithm. In this embodiment, the noise reduction algorithm adopts a deep learning-based voice noise reduction algorithm and is implemented through software programming. The deep learning-based voice noise reduction algorithm is prior art. The technical solution of this embodiment is implemented by calling the existing deep learning-based voice noise reduction algorithm and will not be introduced in detail.

[0026] The preprocessing of the voice collected by the wireless muffler includes audio enhancement processing on the collected sound. Specifically: The wireless muffler optimizes the voice that has undergone noise reduction processing through a preset audio enhancement algorithm to improve the clarity of the voice.

[0027] Audio enhancement: Training voice data containing noise through a deep learning algorithm to distinguish voice and noise. During a call, the audio signal is analyzed in real time to identify and suppress background noise, and at the same time enhance the key frequency components in the voice signal, which is prior art and will not be introduced in detail.

[0028] The audio enhancement algorithm is a prior art and will not be elaborated here in detail. In the process of software programming in this embodiment, an existing audio enhancement algorithm is called to implement audio enhancement processing.

[0029] The preprocessing of the collected voice by the wireless muffler includes audio distortion compensation for the collected voice. Specifically: The wireless muffler performs voice distortion detection through a preset audio distortion detection algorithm to determine whether the voice is distorted; if the voice is distorted, audio compensation is performed.

[0030] The voice distortion detection is specifically: comparing the voice received this time with the voice received for the first time, and determining whether the clarity and loudness of the voice received this time reach those of the voice received for the first time. If the clarity and loudness of the voice received this time do not reach those of the voice received for the first time, it is determined that the voice is distorted this time.

[0031] Among them, the audio distortion detection algorithm is a prior art in this field, and the audio compensation algorithm is a prior art. In the process of software programming in this embodiment, audio distortion detection is performed by calling the audio distortion detection algorithm, and the distorted audio is repaired by calling the audio compensation algorithm. The prior art will not be elaborated here.

[0032] The preprocessing of the collected voice by the wireless muffler includes encryption processing of the collected voice. Specifically: the wireless muffler encrypts the voice data through a preset encryption algorithm, and then compresses the encrypted voice data with a compression algorithm.

[0033] Among them, compressing the voice data with a compression algorithm makes the occupied space of the voice data smaller, reduces the probability of loss of the voice data during transmission, and improves the reliability of voice data transmission.

[0034] Both encrypting the voice data through an encryption algorithm and compressing it with a compression algorithm are prior arts and will not be elaborated in detail.

[0035] S2. The earphone and the wireless muffler establish a communication connection. Specifically: If the earphone is used for the first time, the earphone needs to start establishing a communication connection with the wireless muffler again. After the earphone and the wireless muffler establish a communication connection, the ID information of the connected wireless muffler is stored in the memory list of the earphone. Among them, at least 2 pieces of ID information of the previously connected wireless mufflers can be stored in the memory list.

[0036] If the earphone is not used for the first time, after the earphone is powered on again, the earphone will try to establish a communication connection with each of the wireless silencers in the memory list one by one in the order from the nearest to the farthest in time until the earphone establishes a communication connection with one of the wireless silencers. If all connections fail, the earphone needs to establish a communication connection with a new wireless silencer.

[0037] Among them, when the earphone is connected to a wireless silencer, it will try 2 to 3 times.

[0038] For example, the earphone has previously established communication connections with 3 wireless silencers. In the order from the nearest to the farthest in connection time, the IDs of each wireless silencer stored in the memory list are 1, 2, and 3 respectively.

[0039] After the earphone is powered on, it first tries to establish a communication connection with the wireless silencer with ID 1 and tries 3 times continuously. After that, if the earphone still cannot establish a communication connection with the wireless silencer with ID 1, the earphone tries to establish a communication connection with the wireless silencer with ID 2 and tries 3 times continuously. If the earphone still cannot establish a communication connection with the wireless silencer with ID 2, the earphone tries to establish a communication connection with the wireless silencer with ID 3 and tries 3 times continuously until a communication connection is established with the wireless silencer. If the connection still fails, the earphone can only establish a communication connection with a wireless silencer that has not been connected before and be used in cooperation.

[0040] After the earphone establishes a communication connection with the wireless silencer, the earphone will verify the wireless silencer through a handshake protocol; if the verification fails, the earphone will disconnect from the wireless silencer and add the wireless silencer to the list of prohibited connections.

[0041] Specifically, data verification is performed through the handshake protocol. After the earphone establishes a communication connection with the wireless silencer, the earphone will send a piece of data to the receiving wireless silencer, and the corresponding wireless silencer needs to return a piece of data to the earphone within a preset time.

[0042] If the earphone does not receive the data returned by the wireless silencer within the preset time or the received data is not the data required by the earphone, it means that the current wireless silencer fails the verification. The current wireless silencer will be added to the list of prohibited connections of the earphone. Device verification is performed through the handshake protocol to ensure that the connection will not be made to the wrong device.

[0043] S3: The earphone receives the voice data sent by the wireless silencer, specifically: When a single earphone is used alone, the earphone establishes a communication connection with the wireless muffler to transmit voice data. When two earphones are used simultaneously, the master earphone communicates with the wireless muffler to transmit voice data.

[0044] Specifically, an independent timer is provided inside each earphone. When an earphone establishes a communication connection with the wireless muffler, the timer in the earphone scans whether the other earphone in a pair of earphones has also established a communication connection with the wireless muffler.

[0045] If both the master earphone and the slave earphone of a pair of earphones have established communication connections with the wireless muffler, query through the built-in database of the earphone to determine which is the master earphone and which is the slave earphone. Then, turn off the function of the slave earphone to receive data from the wireless muffler, and only the master earphone receives audio data from the wireless muffler.

[0046] The above process is implemented through software programming.

[0047] If only one earphone establishes a communication connection with the wireless muffler, the earphone receives audio data from the wireless muffler.

[0048] The earphone and the portable wireless muffler achieve wireless communication through Bluetooth or 2.4G.

[0049] This embodiment also provides a system for realizing private calls. Using the communication method for realizing private calls, it includes a calling device, a wireless muffler, and earphones. During a call, the wireless muffler shields the voice emitted by the speaker to achieve private calls.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
