Detailed Description

The following describes in detail a bluetooth headset, an audio output method and an audio output system according to embodiments of the present application with reference to the accompanying drawings.

The terms "comprising" and "having" and any variations thereof, as referred to in the description of the application, are intended to cover non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed but may optionally include other steps or elements not listed or inherent to such process, method, article, or apparatus.

It should be noted that, in the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the description of the present application, unless otherwise indicated, the meaning of "a plurality" means two or more. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone.

As described in the background art, when a loudspeaker box or a wireless loudspeaker box operating in the UHF band or other civil proprietary bands is adopted in the prior art, a microphone in the same proprietary band is also required to cooperatively implement the sound collection and amplification functions, as shown in fig. 1. The audio amplifying circuit designed in the sound amplifying box or the wireless sound box comprises a wireless receiving module, an audio code stream generating module, a digital-to-analog converter (digital to analog converter, DAC), a tone adjusting module, a voltage amplifier, a digital power amplifying module and a loudspeaker. Wherein the voltage amplifier may also be referred to as a potentiometer.

However, the prior art has the problems that the cost of the whole set purchase is high, the whole set purchase is only used for realizing sound amplification after purchase, and the function is single. In addition, the frequency bands used by products of different equipment manufacturers may be different, and there is a problem that the frequency bands are not universal. For example, if the microphone a associated with the loudspeaker box a is damaged during use, the user needs to purchase the microphone a' manufactured by the same manufacturer, or purchase the loudspeaker box B and the microphone B manufactured by another manufacturer. Finding a certain manufacturer to purchase a specific product may cause a lot of inconvenience to the user, or the deactivation of the sound amplification box a due to the damage of the microphone a may cause waste of resources.

At present, as the popularity of the Bluetooth headset is higher, the embodiment of the application can realize the wireless sound amplifying function by improving the function of the Bluetooth headset. Specific functions and technical effects of the bluetooth headset will be described in detail in the following system embodiments, which are not described herein.

As shown in fig. 2, an audio output system 20 is provided according to an embodiment of the present application. The audio output system 20 includes a bluetooth headset 201, an electronic device 202, and an audio device 203. Wherein the audio device 203 may be one or more devices, only one of which is schematically depicted in fig. 2. Illustratively, the bluetooth headset 201 may be a left or right headset of a pair of true wireless stereo (true wireless Stereo, TWS) bluetooth headsets. The electronic device 202 may be a smart phone. The audio device 203 may be a bluetooth speaker. The states of the bluetooth headset 201 include a slave device state and a master device state, and the states of the electronic device 202 include a slave device state and a master device state, for example, the bluetooth headset 201 is bluetooth-connected to the electronic device 202, the bluetooth headset 201 is in the slave device state, and the electronic device 202 is in the master device state.

In fig. 2, a bluetooth headset 201 is used to switch the state of the bluetooth headset 201 from a slave device state to a master device state in response to a switching operation of the bluetooth headset 201 by a user when the bluetooth headset 201 is in the slave device state. The bluetooth headset 201 is further configured to search for the audio device 203 and establish a bluetooth connection with the audio device 203 when the bluetooth headset 201 is in the master device state. In the audio output system provided by the embodiment of the present application, the bluetooth headset 201 after the state switching is in the main device state, and can establish bluetooth connection with the searched audio device 203. Since bluetooth communication occupies a specific frequency band, typically 2.4GHz, bluetooth headset 201 or audio device 203 with bluetooth function is common. That is, any one of the bluetooth headset 201 and any one of the bluetooth-enabled audio devices 203 can realize a sound amplifying function without necessarily requiring purchase and use of the bluetooth headset 201 and the audio device 203 in a set. On the one hand, the production cost and the purchase cost can be saved by the general design, on the other hand, the general design can also enable a user to conveniently find replacement equipment after equipment is damaged, and the resource waste caused by disabling equipment matched with damaged equipment due to the fact that the replacement equipment is not easy to find after the equipment is damaged can also be avoided. In addition, the bluetooth headset 201 may also perform other functions than sound amplification, such as listening to music, watching video, voice conversation, or video chat, as compared to a microphone dedicated to sound amplification.

In some embodiments of the present application, the user's switching operation on the bluetooth headset 201 includes touching the key of the bluetooth headset 201N times, pressing the key for N seconds, or sliding the key up or down, where N is a positive integer. The key for switching operation may be any key customized by the user, such as an up volume key, a down volume key, or a pause play key.

For example, the bluetooth headset 201 may implement state switching through a bluetooth reset or restart.

When the sound amplifying function is not used, the bluetooth headset 201 needs to be restored to the normal slave device state. The user can trigger the switching of the state again by putting the bluetooth headset 201 in the headset box, i.e. switching the bluetooth headset 201 from the master device state to the slave device state.

Illustratively, the bluetooth connection established by the bluetooth headset 201 with the audio device 203 may be a connection-oriented synchronization link (synchronous connection oriented link, SCO).

In some embodiments of the present application, the Bluetooth headset 201 is further configured to determine whether the audio device 203 matches preset Bluetooth device information stored in the Bluetooth headset 201; when the audio device 203 matches the preset bluetooth device information stored in the bluetooth headset 201, a bluetooth connection is established with the audio device 203. That is, in the embodiment of the present application, before the bluetooth headset 201 establishes a bluetooth connection with the audio device 203, it is necessary to determine whether the audio device 203 matches preset bluetooth device information stored in the bluetooth headset 201, and only when the audio device 203 matches, a connection is established, thereby improving the probability of successful connection.

Note that matching the audio device 203 with the preset bluetooth device information stored in the bluetooth headset 201 means that the preset bluetooth device information stored in the bluetooth headset 201 includes device information of the audio device 203. Conversely, the audio device 203 not matching the preset bluetooth device information stored in the bluetooth headset 201 means that the preset bluetooth device information stored in the bluetooth headset 201 does not include the device information of the audio device 203.

In the embodiment of the application, the equipment information comprises an address, or the equipment information comprises an address and a name. The address may be, for example, a media access control (media access control, MAC) address.

In some embodiments of the present application, the bluetooth headset 201 is further configured to broadcast device information of the audio device 203. The bluetooth headset 201 is further configured to establish a bluetooth connection with the audio device in response to a user operation of the audio device 203. That is, in the embodiment of the present application, before the bluetooth headset 201 establishes a bluetooth connection with the audio device 203, the device information of the audio device 203 needs to be broadcasted and operated by the user, so that the probability of successfully connecting to the device that the user desires to connect is increased, and the user experience is further improved.

In the embodiment of the present application, when the audio device 203 matches with the preset bluetooth device information stored in the bluetooth headset 201, the bluetooth headset 201 is further configured to broadcast the device information of the audio device 203.

In general, preset bluetooth device information stored in the bluetooth headset 201 may be arranged in time series. The bluetooth headset 201 may preferentially broadcast the audio device 203 that matches the newly stored preset bluetooth device information.

If the device information of the audio device 203 includes the address and name of the audio device 203, the bluetooth headset 201 may voice-broadcast the name of the audio device 203. When the audio device 203 is a plurality of devices, the bluetooth headset 201 may also voice broadcast the name and corresponding number of the audio device 203. If the device information of the audio device 203 includes the address of the audio device 203, the bluetooth headset 201 voice broadcasts the address of the audio device 203.

In one possible implementation, when the audio device 203 is the only device that matches the preset bluetooth device information stored in the bluetooth headset 201, the bluetooth headset 201 may voice-report the name or address of the audio device 203. At this time, the user's operation on the audio device 203 may be a touch operation, for example, the user clicks a button to confirm bluetooth connection with the audio device 203.

In another possible implementation manner, when the audio device 203 is one of a plurality of devices that match the preset bluetooth device information stored in the bluetooth headset 201, the bluetooth headset 201 may broadcast the names of the plurality of devices that match the preset bluetooth device information stored in the bluetooth headset 201 in voice, for example, "name 1, name 2, … … name M", where M is a positive integer greater than 1, and at this time, the operation of the audio device 203 by the user may be a touch operation, for example, the user clicks a certain key J times to select the audio device 203 corresponding to the name J to perform bluetooth connection, where J is a positive integer and satisfies 1+.j+.m. For example, further, the bluetooth headset 201 may voice-broadcast "name 1, name 2, … … name M, please say the device name to be connected", at which time the user's operation on the audio device 203 may be a voice control operation, for example, the user say "name J" to select the audio device 203 corresponding to the name J to perform bluetooth connection. Alternatively, the bluetooth headset 201 may voice-report names and corresponding numbers of a plurality of devices that match the preset bluetooth device information stored in the bluetooth headset 201, for example, "1, name 1,2, name 2, … … M, name M, please speak the numbers corresponding to the devices to be connected. At this time, the operation of the audio device 203 by the user may be a voice control operation, for example, the user speaks "J" to select the audio device 203 corresponding to the name J to make bluetooth connection. In addition, the bluetooth headset 201 may also voice broadcast the name of one of the plurality of devices that matches the preset bluetooth device information stored in the bluetooth headset 201 each time until the user selects the audio device 203 corresponding to the name J to connect through a touch operation or a voice control operation. For example, the bluetooth headset 201 broadcasts "please ask whether to connect with the name 1", and if the user does not have any operation or speaks "no" for a preset time, the bluetooth headset 201 continues to broadcast "please ask whether to connect with the name 2". If the user clicks a certain preset button or says "yes", the bluetooth headset 201 does not perform voice broadcast any more, but connects with the audio device 203 corresponding to the name 2.

In yet another possible implementation, when the audio device 203 is a plurality of devices among a plurality of devices that match the preset bluetooth device information stored in the bluetooth headset 201, the user's operation on the audio device 203 may be a voice control operation. The bluetooth headset 201 may voice-report names of a plurality of devices that match preset bluetooth device information stored in the bluetooth headset 201, for example, "name 1, name 2, … … name M, please say the device name to be connected", at which time, the user may select the audio device 203 corresponding to the name J and the audio device 203 corresponding to the name H to perform bluetooth connection by say "name J, name H", J, H are both positive integers and satisfy j+.h, 1+.j+.m, 1+.h.ltoreq.m. Alternatively, the bluetooth headset 201 may voice-report names and corresponding numbers of a plurality of devices that match the preset bluetooth device information stored in the bluetooth headset 201, for example, "1, name 1,2, name 2, … … M, name M, please speak the numbers corresponding to the devices to be connected. At this time, the user can select the audio device 203 corresponding to the name J and the audio device 203 corresponding to the name H to make bluetooth connection by speaking, for example, "J, H".

In some embodiments of the present application, the electronic device 202 is configured to send device information of the audio device 203 to the bluetooth headset 201 through a bluetooth connection with the bluetooth headset 201. A bluetooth headset 201 for receiving and storing device information of an audio device 203 transmitted by an electronic device 202. In the embodiment of the present application, before the bluetooth headset 201 performs the state switching, the bluetooth headset 201 is in the slave device state, and the electronic device 202 is in the master device state. So that the electronic device 202 can send information to the bluetooth headset 201 via bluetooth.

The preset bluetooth device information stored in the bluetooth headset 201 may include device information of a bluetooth device to which the bluetooth headset 201 is connected, and may also include device information of a bluetooth device from the electronic device 202 to which the bluetooth headset 201 is not connected.

In some embodiments of the present application, the electronic device 202 is configured to send device information of the audio device 203 to the bluetooth headset 201 in response to an operation of selecting the audio device 203 from devices searched by the user from the electronic device 202. In the embodiment of the present application, since the bluetooth headset 201 has no screen, the search for devices can be completed by means of the on-screen electronic device 202, and the audio device 203 can be selected from the searched devices. Such visual selection operations help to enhance the user's experience.

Illustratively, as shown in FIG. 3, a user may open an application on the electronic device 202 that controls the Bluetooth headset 201, the electronic device 202 entering an interface as shown at 3A in FIG. 3. For example, the interface may include the name of the bluetooth headset 201, the icon and name of the currently connected device, voice related touch keys, and smart-cut related touch keys. Wherein, 3A in fig. 3 exemplarily shows icons and names corresponding to two connected devices.
