Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

A wireless earphone and a method for outputting audio data by using the wireless earphone provided by the present invention will be described in detail below by enumerating several specific embodiments.

Embodiment one

A wireless earphone provided by an embodiment of the present invention is introduced in detail.

Referring to FIG. 1 , it shows a schematic structural diagram of a wireless earphone in an embodiment of the present invention.

The wireless earphone in the embodiment of the present invention includes: a main earphone 110 and an auxiliary earphone 120 . Wherein, the main headset 110 includes: an audio receiving module 111 and a first audio processing module 112 ; the auxiliary headset 120 includes: a second audio processing module 121 .

The functions of each module and the interaction between each module are introduced in detail below.

The main headset 110 includes:

The audio receiving module 111 is configured to obtain audio data in a wireless manner.

Wherein, the wireless manner may also be understood as a wireless transmission manner, and refers to a manner of performing data transmission using a wireless technology. Among them, the communication that can use electromagnetic waves to send and receive signals in free space is wireless transmission. Wireless communication methods include radio wave transmission, microwave transmission, Bluetooth transmission and infrared transmission.

The principle of radio wave transmission is that audio data can be loaded onto radio waves by modulation. When the radio wave propagates to the receiving end, the electromagnetic field change caused by the radio wave will generate a current in the conductor at the receiving end. The purpose of information transmission is achieved by extracting audio data from current changes through demodulation.

Microwave transmission may specifically include analog microwave transmission and digital microwave transmission. Among them, microwave is a kind of radio wave. Analog microwave transmission means that the transmitting end directly modulates the original signal on the microwave channel, and then transmits it; after receiving the microwave signal, the receiving end can undergo corresponding demodulation processing to obtain the original signal. Digital microwave transmission means that the sending end first encodes and compresses the original signal, and then modulates it through a digital microwave channel before transmitting it; after receiving the microwave signal, the receiving end first demodulates and then decodes and decompresses it, and finally restores the original analog signal . Wherein, the microwave signal used to modulate the original signal may be called a carrier signal.

The wavelength of infrared rays is between 0.75μm (micrometer) and 1mm (millimeter). Infrared transmission has the characteristics of low cost, cross-platform, small angle, short distance, point-to-point straight line data transmission, and has a good performance in confidentiality and transmission rate. However, in the process of infrared transmission, the positions of the sending end and the receiving end that require communication are relatively fixed, and its point-to-point transmission connection also makes it impossible to form a network flexibly. Infrared rays are mostly used for indoor short-distance transmission, but many applications are gradually being transmitted by Bluetooth. replaced.

The transmission distance of Bluetooth transmission is about 10 meters. It supports point-to-point and point-to-multipoint communication. It works at the global 2.4GHz (megahertz). Currently, the most commonly used wireless method for obtaining audio data is Bluetooth transmission. Of course, it can also The audio data is obtained by using other wireless transmission methods, which is not limited in this embodiment of the present invention. Moreover, in the embodiment of the present invention, the electromagnetic waves specifically used in the wireless mode may be determined before this step, or any step before this step according to requirements, which is not limited in this embodiment of the present invention.

In practical applications, audio data can be stored in mobile terminals such as mobile phones, tablet computers, personal digital assistants (Personal Digital Assistant, PDA), vehicle-mounted computers, vehicle-mounted stereos, and computers. Of course, the audio data may also exist in the cloud or network, etc., which is not limited in this embodiment of the present invention. Therefore, in the embodiment of the present invention, obtaining audio data wirelessly may specifically include obtaining audio data wirelessly from a mobile terminal; or obtaining audio data from a cloud server or a network server. Taking the mobile terminal as an example, the receiving end is the main headset, specifically the audio receiving module of the main headset, and the sending end is the mobile terminal. The mobile terminal can send out audio data in any of the above wireless ways, and the audio receiving module of the main headset can correspondingly receive the audio data sent by the mobile terminal in a corresponding wireless way.

The first audio processing module 112 is configured to extract the first channel signal corresponding to the main headset from the audio data, and send the first channel signal to the main headset speaker for playback; and, from the audio data Extracting the second sound channel signal corresponding to the auxiliary headset, and wirelessly sending the second sound channel signal to the auxiliary headset based on the carrier signal satisfying the preset condition; the preset condition includes: the frequency of the carrier signal is at Within the first frequency range, and the pulse of the carrier signal satisfies the first pulse condition, and/or the duty cycle of the carrier signal satisfies the first duty cycle condition.

In practical applications, if a pair of earphones includes two headsets, the main headset and the auxiliary headset, then the corresponding outputs of the main headset and the auxiliary headset are part of the audio data. For example, audio data can be divided into left channel signal and right channel signal, then the left channel signal can be sent to the main headset or auxiliary headset, and the right channel can be sent to another headset, for example, the left channel signal Send to the main headset, the right channel signal is sent to the auxiliary headset. Wherein, the left channel signal is a sound output generated by simulating the hearing range of the human left ear. Generally, it can include the low-frequency region signal in the audio data, and the vocal dialogue and transliteration are mostly in the left channel signal. The right channel signal is the opposite of the left channel signal, and is a sound output that simulates the hearing range of the human right ear.

In the embodiment of the present invention, the audio data can be divided into two channel signals, wherein the channel signal corresponding to the main headset is called the first channel signal, and the channel signal corresponding to the auxiliary headset is called the second channel signal. The two-channel signal, wherein the method of specifically dividing the first channel signal and the second channel signal can be set before this step, or before any step before this step according to requirements, and this embodiment of the present invention does not add limited.

In the embodiment of the present invention, the first audio processing module may extract the first channel signal corresponding to the main headset from the audio data, and send the extracted first channel signal to the main headset speaker for playback. In addition, in order to make the playing effect of the first channel signal better, devices such as amplifiers and digital-to-analog conversion can also be added inside the main headset, so that after the first audio processing module extracts the first channel signal, it first uses the amplifier to The first channel signal is amplified and converted to analog before being sent to the main headset speaker for playback. Moreover, if the signal containing the audio data sent by the mobile terminal is a digital signal when the audio data is acquired from the mobile terminal, then the main headset may further include a digital-to-analog converter to convert the digital signal received wirelessly into an analog signal, Therefore, the playback effect of the first channel signal extracted from the audio signal is more natural.

Specifically, the first sound channel signal can be transmitted between various modules or devices inside the main headset by using a wireless transmission method; of course, the first sound channel signal can also be transmitted between various modules or devices inside the main headset by a wired method. The various modules or devices that need to communicate need to be connected by wires.

In addition, in the embodiment of the invention, the first audio processing module may also extract the second sound channel signal corresponding to the auxiliary headset from the audio data, and wirelessly send the second sound channel signal to the auxiliary headset. Wherein, the wireless mode for sending the second sound channel signal to the auxiliary headset can be set before this step, or before any step before this step according to requirements, which is not limited in this embodiment of the present invention. Moreover, the wireless method of sending the second channel signal to the auxiliary headset and the wireless method used by the aforementioned audio receiving module to obtain audio data may be the same wireless transmission method, of course, may also be a different wireless transmission method, for which the present invention implements Examples are not limited.

In practical applications, Bluetooth has two inherent defects: (1) The frequency of the Bluetooth signal is relatively high, as mentioned above, generally 2.4GHz, then the wavelength of the Bluetooth signal λ=c/f=3×10 ⁸ /(2.4×10 ⁹ )=12.5 cm, where λ is the wavelength, c is the speed of light, and f is the frequency. It can be seen that the wavelength of the Bluetooth signal is relatively short, so the diffraction ability is weak; (2) Bluetooth transmission is a low-power transmission, and the transmission power is limited, so the penetration ability is also limited. In the embodiment of the present invention, if the main headset still uses the bluetooth transmission method to transmit the second sound channel signal to the auxiliary headset. Due to the above two defects, if Bluetooth transmission is still used between the main headset and the auxiliary headset, then when the main headset and the auxiliary headset are worn on the left and right ears respectively, the Bluetooth signal is easily blocked by the head, so it is very easy to cause the second sound. The channel signal is damaged.

As analyzed above, the wavelength of electromagnetic waves has a great relationship with the diffraction ability. In order to improve the diffraction ability, the wavelength needs to be lengthened. According to the aforementioned formula λ=c/f, it can be seen that the wavelength can be lengthened by reducing the frequency of electromagnetic waves. . If the difference between the wavelength of the electromagnetic wave and the distance between the human ears exceeds a certain length threshold, the trouble of being blocked by the electromagnetic wave can be effectively avoided. Generally, the distance between the two ears of a person is about 15 cm. If the wavelength of the electromagnetic wave exceeds four times the distance between the two ears of a person, that is, the wavelength of the electromagnetic wave is about 75 cm. At this time, the electromagnetic wave can be effectively prevented from being blocked. The fixed length threshold is 60 cm.

Therefore, in the embodiment of the present invention, the second sound channel signal can be wirelessly sent to the auxiliary headset based on the carrier signal satisfying the preset condition, for example, the electromagnetic wave satisfying the preset condition can be used as the carrier signal to encode the The second channel signal is modulated, so that the wavelength of the modulated second channel signal can be effectively avoided from being blocked. The preset condition may be set before this step, or any step before this step, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, the preset condition may include that the frequency of the carrier signal is within a first frequency range. For example, the frequency of the carrier signal is between 500kHz (kilohertz) and 500MHz. The specific value of the first frequency range can be set before this step, or any step before this step according to requirements, which is not limited in this embodiment of the present invention.

In addition, in the embodiment of the present invention, in order to ensure that the second channel signal sent from the main earphone of the same earphone can be sent to the corresponding auxiliary earphone, and will not be sent to other earphones that do not belong to the same earphone as the main earphone In the auxiliary headset, the carrier signal of the main headset can be uniquely set, and at the same time, the auxiliary headset corresponding to the main headset can only receive the second audio signal that meets the specially set conditions. Therefore, in the embodiment of the present invention, the preset condition that the carrier signal satisfies may also include that the pulse of the carrier signal satisfies the first pulse condition, and/or the duty ratio of the carrier signal satisfies the first duty ratio condition. The duty cycle refers to the time ratio of the high level within one cycle. For example, it can be set that the carrier signal of a main headset used to modulate the second channel signal has two pulse signals in one cycle, or the duty cycle is 0.3, then the modulated second channel signal also meets this requirement. conditions, then it is set that only the auxiliary headset corresponding to the main headset can receive two pulse signals in one cycle, or a signal with a duty ratio of 0.3, and other main headsets or auxiliary headsets cannot receive signals that meet the above conditions. Signal. Of course, the first pulse condition may also include a limitation on the pulse position, etc., which are not limited by the implementation of the present invention. Moreover, before this step, or before any step before this step, the first pulse condition and the first duty cycle condition can be set according to the specific situation of the current earphone, which is not limited by this embodiment of the present invention. .

Auxiliary headset 120 includes:

The second audio processing module 121 is configured to acquire the second sound channel signal in a wireless manner, and send the second sound channel signal to the auxiliary earphone speaker for playback.

In the implementation of the present invention, the auxiliary headset includes a second audio processing module, which can wirelessly acquire the second channel signal wirelessly sent by the first audio processing module of the main headset. Wherein, before the first audio processing module transmits the second channel signal wirelessly, it may first encode the second channel signal, and use a carrier signal to modulate the encoded second channel signal, and then encode the second channel signal The modulated second channel signal is sent to the auxiliary headset wirelessly, then the second audio processing module of the auxiliary headset can receive the coded and modulated second channel signal wirelessly, and then use the decoding and The demodulation device sequentially performs corresponding decoding processing and demodulation processing on the received coded and modulated second sound channel signal, so as to obtain the second sound channel signal. Certainly, before the first audio processing module transmits the second channel signal in a wireless manner, the second channel signal may not be encoded, but the encoded second channel signal is only modulated by the carrier signal, then the auxiliary The second audio processing module of the headset receives the modulated second channel signal wirelessly, and then uses the demodulation device of the auxiliary headset to perform corresponding demodulation processing on the received modulated second channel signal, thereby Get the second channel signal.

After the second audio processing module acquires the second sound channel signal, it can also send the second sound channel signal to the auxiliary headset speaker for playback. Similarly, the auxiliary headset may also include an amplifier to amplify the second sound channel signal. If the second channel signal is a digital signal, the auxiliary headset may further include a digital-to-analog converter to convert the second channel signal in the form of a digital signal into the second channel signal in the form of an analog signal.

The embodiment of the present invention introduces a wireless earphone, the earphone has a main earphone and an auxiliary earphone. The main headset includes: an audio receiving module, configured to acquire audio data wirelessly; a first audio processing module, configured to extract a first channel signal corresponding to the main headset from the audio data, and send the first The channel signal is played to the speaker of the main headset; and, the second channel signal corresponding to the auxiliary headset is extracted from the audio data, and the second channel signal is wirelessly sent based on the carrier signal satisfying the preset condition To the auxiliary headset; the preset condition includes: the frequency of the carrier signal is within the first frequency range, and the pulse of the carrier signal satisfies the first pulse condition, and/or the duty cycle of the carrier signal satisfies the first pulse condition a duty cycle condition.
