Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a headphone. Background Technology

[0002] Currently, widely used headphones mainly include wired headphones, Bluetooth headphones, and wireless live streaming headphones. Among them, wired headphones can only be connected to external devices via a data cable, Bluetooth headphones can only be connected to external devices wirelessly via Bluetooth technology, and wireless live streaming headphones require a wireless receiver that can be plugged into an external device to achieve a wireless connection. It can be seen that currently widely used headphones only support one connection method, that is, either wired connection to an external device or wireless connection to an external device.

[0003] However, with the development of the live streaming industry, more and more people are choosing to sing online through live streaming. Live streaming has high requirements for network. When users sing live using headphones, the accompaniment music in the live streaming room is easily affected by the network during transmission, resulting in problems such as stuttering and delay. If users sing according to the accompaniment music they hear, it is very easy for the vocals to not match the accompaniment music in the live streaming room, thus resulting in a poor live singing effect.

[0060] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0061] The core of this invention is to provide an earphone that can simultaneously connect to two external devices via wired and wireless connections and play the sound from both external devices, as well as transmit the sound collected by the audio acquisition component to the wired external device. This expands the range of applications and, in live singing scenarios, better matches the vocals with the background music in the live stream, thus improving the live singing effect.

[0062] See Figure 1 As shown, this utility model embodiment discloses an earphone, including:

[0063] The earphone body 1 includes a housing 101, a sound-generating component 102, a device connection component 103, an audio acquisition component 104, a main control chip 105, and a battery 106. The sound-generating component 102, the device connection component 103, the main control chip 105, and the battery 106 are all located inside the housing 101, and the sound-generating component 102, the device connection component 103, and the battery 106 are electrically connected to the main control chip 105.

[0064] Pluggable transmission line 2, used to connect to a first external device;

[0065] The device connection component 103 includes at least one wired interface 1031 and at least one wireless interface 1032; the main control chip 105 is wired to the first external device through the wired interface 1031 and the pluggable transmission line 2, and the main control chip 105 is wirelessly connected to the second external device through the wireless interface 1032. The main control chip 105 is used to receive the power supply signal transmitted by the first external device and output an enable signal to enable or disable the power supply function to the battery 106, and to transmit the device audio signal of the first external device and / or the second external device to the sound-emitting component 102.

[0066] The audio acquisition component 104 is electrically connected to the main control chip 105; the main control chip 105 is used to transmit the acquired audio signal from the audio acquisition component 104 to the first external device.

[0067] The audio acquisition component 104 is electrically connected to the main control chip 105, and the main control chip 105 is electrically connected to the sound-emitting component 102. At this time, the main control chip 105 can also be used to transmit the audio signal acquired by the audio acquisition component 104 to the sound-emitting component 102 for playback, so that the user can hear their own voice.

[0068] The headphone body 1 can be either a headphone or a neckband headphone; no specific limitation is made here.

[0069] In one example, such as Figure 2 As shown, the headphone body 1 is a headphone. At this time, the housing 101 includes a first housing 1011 and a second housing 1012, and the sound-emitting component 102 includes a first sound-emitting component 1021 and a second sound-emitting component 1022. The first sound-emitting component 1021 is located in the first housing 1011, and the second sound-emitting component 1022 is located in the second housing 1012. The first housing 1011 and the second housing 1012 are connected by a first connector 107.

[0070] It should be noted that the device connection component 103, the main control chip 105, and the battery 106 can all be located in the first compartment 1011, all in the second compartment 1012, or they can be distributed in the first compartment 1011 and the second compartment 1012. No specific limitation is made here.

[0071] In one example, such as Figure 3 As shown, the headphone body 1 is a neckband headphone. In this case, the housing 101 includes a first housing 1011, a second housing 1012, a third housing 1013, and a fourth housing 1014. The sound-generating component 102 includes a first sound-generating component 1021 and a second sound-generating component 1022. The first sound-generating component 1021 is located inside the first housing 1011, the second sound-generating component 1022 is located inside the second housing 1012, the battery 106 is located inside the third housing 1013, and the device connection component 103 and the main control chip 105 are located inside the fourth housing 1014. Furthermore, the first housing 1011 is connected to the third housing 1013 via a second connector 108, the second housing 1012 is connected to the fourth housing 1014 via a third connector 109, and the third housing 1013 and the fourth housing 1014 are connected by a fourth connector 110.

[0072] Furthermore, the fourth compartment 1014 also features multiple function buttons, from left to right: volume up, volume down, play / pause / Bluetooth, and power / earphone monitoring. The play / pause / Bluetooth button corresponds to different commands depending on the button press; for example, a short press while music is paused plays the music, a short press while music is playing pauses the music, and a long press turns on Bluetooth. Similarly, the power / earphone monitoring button also corresponds to different commands depending on the button press; for example, a long press while the headphones are off turns them on, a long press while they are on turns them off, and a short press while they are on turns on turns on earphone monitoring. Turning on earphone monitoring here means that the main control chip 105 transmits the audio signal collected by the audio acquisition unit 104 to the sound-emitting unit 102 for playback, allowing the user to hear their own voice. Other function buttons can also be installed within the compartment 101, and the commands for each function button are executed by the main control chip 105.

[0073] It should be noted that, for the device connection component 103, the main control chip 105, and the battery 106, in addition to the aforementioned arrangement where the battery 106 is located in the third compartment 1013 and the device connection component 103 and the main control chip 105 are located in the fourth compartment 1014, the device connection component 103, the main control chip 105, and the battery 106 can all be located in the third compartment 1013 or the fourth compartment 1014, or the device connection component 103 and the main control chip 105 can be located in the third compartment 1013 and the battery 106 can be located in the fourth compartment 1014. There are many similar cases, which will not be listed here.

[0074] It should also be noted that the sound-generating component 102 can be a loudspeaker.

[0075] The audio acquisition component 104 can be a microphone, and the position of the audio acquisition component 104 in the headphones of this utility model can be varied.

[0076] In one example, if the headphone body 1 is a neckband headphone, the audio acquisition component 104 can be located on the second connector 108 or the third connector 109. Figure 3 For example, the audio acquisition component 104 is located on the third connector 109 of the neckband headphones.

[0077] In one example, the audio acquisition component 104 is located inside the housing 101. If the headphone body 1 is a headphone, the audio acquisition component 104 may be located inside the first housing 1011 and / or the second housing 1012. If the headphone body 1 is a neckband headphone, the audio acquisition component 104 may be located inside the third housing 1013 and / or the fourth housing 1014.

[0078] In one example, the housing 101 also includes an audio interface 111 for pluggable connection to the audio acquisition component 104. Specifically, the audio interface 111 is electrically connected to the main control chip 105. Electrical connection between the audio acquisition component 104 and the main control chip 105 is achieved by inserting the audio acquisition component 104 into the audio interface 111 within the housing 101. Figure 4 As shown, taking the headphone body 1 as an example of a headphone, the audio interface 111 and the audio acquisition component 104 are illustrated.

[0079] The audio interface 111 can be either a USB (Universal Serial Bus) female connector, such as a USB Type-C interface, or a 3.5mm interface.

[0080] The device connection component 103 includes at least one wired interface 1031 and at least one wireless interface 1032. The wired interface 1031 is used for wired connection to a first external device via a pluggable transmission cable 2, wherein one end of the pluggable transmission cable 2 is pluggably connected to the wired interface 1031 and the other end is pluggably connected to the first external device. The wireless interface 1032 is used for wireless connection to a second external device. The device connection component 103 is also electrically connected to the main control chip 105. Therefore, the main control chip 105 can be wiredly connected to the first external device via the wired interface 1031 and the pluggable transmission cable 2, and can also be wirelessly connected to the second external device via the wireless interface 1032.

[0081] In one example, the wired interface 1031 can be a USB female connector, such as a USB Type-C interface, a Micro USB interface, etc.

[0082] Furthermore, considering that one end of the pluggable transmission cable 2 needs to be compatible with the wired interface 1031 and the other end needs to be compatible with the interface of the first external device, the pluggable transmission cable 2 is a CC transmission cable when both the wired interface 1031 and the interface of the first external device are USB Type-C interfaces; when the wired interface 1031 is a USB Type-C interface and the interface of the first external device is a USB Type-A interface, the pluggable transmission cable 2 is a CA transmission cable. There are many similar cases, which will not be listed here.

[0083] In one example, the wireless interface 1032 can be a Bluetooth interface, a StarScan interface, a UHF (Ultra High Frequency) interface, a 2.4GHz wireless interface, a 5.8GHz wireless interface, etc.; among which, the UHF interface usually refers to the wireless communication interface of the UHF band, which is mainly used for devices such as wireless microphones and wireless headphones. Its operating frequency range is 300MHz to 3GHz, which belongs to a dedicated radio frequency band.

[0084] It should be noted that when the main control chip 105 is wired to the first external device through the wired interface 1031 and the pluggable transmission line 2, the main control chip 105 will detect whether the first external device has audio transmission function and power supply function.

[0085] Regarding whether the first external device has an audio transmission function, the wired interface 1031 is provided with a pin for audio transmission. The main control chip 105 is electrically connected to the pin to detect the resistance value of the pin and output an enable signal to start or stop operation to the sound-generating component 102 and the audio acquisition component 104.

[0086] Specifically, when the resistance value is not lower than the preset resistance value, the main control chip 105 determines that the first external device has audio transmission function and outputs an enable signal to start operation to the sound-emitting component 102 and the audio acquisition component 104 to control the sound-emitting component 102 and the audio acquisition component 104 to start operation; when the resistance value is lower than the preset resistance value, the main control chip 105 determines that the first external device does not have audio transmission function and outputs an enable signal to stop operation to the sound-emitting component 102 and the audio acquisition component 104 to control the sound-emitting component 102 and the audio acquisition component 104 to stop operation.

[0087] Regarding whether the first external device has a power supply function, the wired interface 1031 is provided with a power supply pin. The main control chip 105 is electrically connected to the power supply pin to detect the voltage value of the power supply pin and output an enable signal to enable or disable the power supply function to the battery 106.

[0088] Specifically, when the voltage value of the power pin is zero, the main control chip 105 determines that the first external device does not have a power supply function and outputs an enable signal to enable the power supply function to the battery 106 to control the battery 106 to power the headphones. At this time, the main control chip 105 will receive the power supply signal transmitted by the battery 106. When the voltage value of the power pin is greater than zero and lower than a preset voltage value, the main control chip 105 determines that the first external device has a power supply function but the power is low. At this time, it outputs an enable signal to enable the power supply function to the battery 106 to control the battery 106 to power the headphones. At this time, the main control chip 105 will not only receive the power supply signal transmitted by the battery 106, but also... The device also receives power supply signals from the battery 106. When the voltage value of the power supply pin is not lower than the preset voltage value, the main control chip 105 determines that the first external device has a power supply function and the power is high. At this time, it outputs an enable signal to disable the power supply function to the battery 106 and outputs a charging signal to the wired interface 1031 so that the wired interface 1031 splits the power supply signal transmitted by the first external device into two paths. One path charges the battery 106 through the charging circuit, and the other path is transmitted to the main control chip 105 to power the headphones. At this time, the main control chip 105 will receive the power supply signal transmitted by the first external device.

[0089] It should be noted that a charging circuit is also provided inside the compartment 101, and the input terminal of the charging circuit is connected to the output terminal of the wired interface 1031, while the output terminal of the charging circuit is connected to the input terminal of the battery 106.

[0090] In one example, battery 106 may be a lithium battery, such as a polymer lithium battery and a rechargeable coin cell lithium battery.

[0091] In one example, the main control chip 105 is a chip with audio processing and power supply control functions. For example, the main control chip 105 can be a DSP (Digital Signal Processing) chip.

[0092] In addition to integrating power supply and audio transmission functions into the wired interface 1031, this utility model can also provide a dedicated charging interface inside the housing 101 for pluggable connection with a charging device. The dedicated charging interface is electrically connected to the battery 106 so that when the charging device is inserted into the dedicated charging interface, the dedicated charging interface receives the charging signal from the charging device and transmits the charging signal to the battery 106 to charge the battery 106.

[0093] Furthermore, the dedicated charging interface can also be electrically connected to the battery 106 via the charging circuit, and is used to transmit the charging signal of the charging device to the battery 106 through the charging circuit to charge the battery 106.

[0094] In one example, the charging device includes, but is not limited to, a power bank, a charger connected to a charging socket, etc.

[0095] like Figure 1 As shown, considering that the headphones of this utility model can be wired to the first external device through the wired interface 1031 and the pluggable transmission line 2, and wirelessly connected to the second external device through the wireless interface 1032, the main control chip 105 can receive the device audio signals of the first external device and the second external device, and transmit the device audio signals of the first external device and the second external device to the sound-emitting component 102 for playback, and receive the acquired audio signals transmitted by the audio acquisition component 104, and transmit the acquired audio signals of the audio acquisition component 104 to the first external device through the wired interface 1031 and the pluggable transmission line 2, so that the first external device can perform corresponding business processing on the received audio signals.

[0096] In one example, such as Figure 5 As shown, taking the headphone body 1 as a neckband headphone, the first external device as a live streaming device, and the second external device as an audio device as an example, the first external device will obtain the live audio signal from the running live streaming software and transmit the live audio signal to the headphone through the pluggable transmission cable 2 and the wired interface 1031. The second external device will obtain the accompaniment audio signal from the running music software and transmit the accompaniment audio signal wirelessly to the headphone. Correspondingly, the headphone will receive the live audio signal and the accompaniment audio signal and play them through the sound-emitting component 102. At this time, the user can sing according to the accompaniment audio signal. The audio acquisition component 104 in the headphone will simultaneously acquire the human voice signal and transmit the human voice signal to the first external device through the wired interface 1031 and the pluggable transmission cable 2, so that the first external device can transmit the human voice signal to other devices currently communicating with the first external device through a preset communication network, thereby realizing the functions of live singing and interaction through wired and wireless means.

[0097] The second external device obtains the accompaniment audio signal from the running music software. This can include obtaining a pre-cached accompaniment audio signal from the music software, or obtaining the accompaniment audio signal in real time from the cloud music library through the music software.

[0098] It should be noted that since individual music playback has lower network requirements and can be pre-cached on the audio device, the accompaniment music on the audio device has almost no issues such as stuttering or delay. However, the sound from the live streaming device is easily affected by the network during transmission. Therefore, by connecting the live streaming device and the audio device simultaneously via wired and wireless connections, users can sing along to the accompaniment music on the audio device and transmit their vocals to the live streaming device via wired connection for interactive singing. This allows for a better match between the vocals and the accompaniment music in the live stream, and compared to wireless transmission, it can guarantee sound quality and improve the live singing experience.

[0099] In order to enable the simultaneous connection to and playback of audio signals from two external devices, the headphones of this invention, in addition to establishing electrical connections between the various components in the hardware, also require pre-configuring in the software a protocol that allows the wireless interface 1032 and the wired interface 1031 to connect to external devices simultaneously, as well as a protocol that allows the simultaneous reception and playback of audio signals transmitted from two external devices.

[0100] like Figure 6 As shown, the headphones of this invention can connect to two external devices simultaneously via both the wired interface 1031 and the wireless interface 1032, or connect to a first external device solely via the wired interface 1031. Specifically, the main control chip 105 is wired to the first external device via the wired interface 1031 and the pluggable transmission cable 2, and transmits the device audio signal of the first external device to the sound-emitting component 102 for playback. It also receives the acquired audio signal transmitted by the audio acquisition component 104 and transmits the acquired audio signal from the audio acquisition component 104 to the first external device via the wired interface 1031 and the pluggable transmission cable 2, so that the first external device can perform corresponding business processing on the received audio signal.

[0101] In one example, such as Figure 7 As shown, taking the headphone body 1 as a neckband headphone and the first external device as a singing device as an example, the first external device will obtain the accompaniment audio signal from the running singing software and transmit the accompaniment audio signal to the headphone through the pluggable transmission cable 2 and the wired interface 1031; correspondingly, the headphone will receive the accompaniment audio signal and play it through the sound-emitting component 102. At this time, the user can sing according to the accompaniment audio signal. The audio acquisition component 104 in the headphone will simultaneously acquire the human voice signal and transmit the human voice signal to the first external device through the wired interface 1031 and the pluggable transmission cable 2, so that the first external device can record the human voice signal and perform operations such as singing scoring and uploading of the recorded human voice, thereby realizing the function of wired singing.

[0102] like Figure 8As shown, the headphones of this invention can also be connected to a second external device via the wireless interface 1032. Specifically, the main control chip 105 is wirelessly connected to the second external device via the wireless interface 1032, receives the device audio signal transmitted by the second external device, and transmits the device audio signal of the second external device to the sound-emitting component 102 for playback.

[0103] In one example, such as Figure 9 As shown, taking the headphone body 1 as a neckband headphone and the second external device as an audio device as an example, the second external device will obtain the audio signal from the running music software and transmit the audio signal to the headphone through the wireless interface 1032; accordingly, the headphone will receive the audio signal transmitted by the second external device and play it through the sound-emitting component 102, thereby realizing the function of wireless music listening.

[0104] Furthermore, the headphones of this utility model also have sound effect processing functions, which can perform sound effect processing on the device audio signal of external devices and / or the audio signal acquired by the audio acquisition component 104, such as reverb, pitch shifting, modulation, compression, speed adjustment, volume adjustment, mixing, EQ (Equalizer) equalization adjustment, etc., so as to achieve more types and stronger sound effects.

[0105] In one example, such as Figure 10 As shown, without considering the transmission of the audio signal acquired by the audio acquisition unit 104 to the sound-emitting unit 102, the main control chip 105 may include a first sound effect processing unit 1051. The input terminal of the first sound effect processing unit 1051 is connected to the output terminal of the wireless interface 1032 and the output terminal of the wired interface 1031, respectively, and the output terminal of the first sound effect processing unit 1051 is connected to the input terminal of the sound-emitting unit 102.

[0106] That is, the first audio processing unit 1051 is used to receive the device audio signal of the first external device transmitted by the wired interface 1031 and the device audio signal of the second external device transmitted by the wireless interface 1032. Then, it performs audio processing on the device audio signals of the first external device and the second external device to obtain the first audio processing signal and the second audio processing signal, and directly transmits the first audio processing signal and the second audio processing signal to the sound-emitting unit 102 for playback.

[0107] The sound processing functions of the first sound processing component 1051 include, but are not limited to, EQ equalization adjustment, reverb, pitch shifting, speed shifting, modulation, compression, and volume adjustment.

[0108] It should be noted that the headphones of this utility model can play the first sound effect processed signal and the second sound effect processed signal through the first sound-emitting component 1021 and the second sound-emitting component 1022 respectively.

Then, it performs audio processing on the device audio signals of the first external device and the second external device to obtain the first audio processing signal and the second audio processing signal, and transmits the first audio processing signal and the second audio processing signal to the mixing processing unit 1052. The mixing processing unit 1052 is used to perform mixing processing on the first audio processing signal and the second audio processing signal to synthesize the first audio processing signal and the second audio processing signal into a mixed signal, and transmits the mixed signal to the sound-emitting unit 102 for playback.

The output terminal of the mixing processing unit 1052 is connected to the input terminal of the sound generating unit 102.

[0115] That is, the mixing processing unit 1052 is used to mix the device audio signal of the first external device, the device audio signal of the second external device, and the audio signal acquired by the audio acquisition unit 104 to synthesize one or two mixed signals, and transmit the mixed signal to the sound-generating unit 102 for playback.

[0116] It should be noted that when synthesizing two mixed signals, the headphones of this invention can play the two mixed signals respectively through the first sound-emitting component 1021 and the second sound-emitting component 1022.

[0117] Furthermore, when synthesizing two mixed signals, the mixing processing unit 1052 can synthesize any two of the device audio signals of the first external device, the device audio signals of the second external device, and the audio signals acquired by the audio acquisition unit 104 into one mixed signal, and use the remaining one as the other mixed signal.
