The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

1 , the present invention provides a speaker, including a speaker body 130, and a first storage compartment 131 disposed on the speaker body 130 for accommodating the first wireless earphone 140. The first storage compartment 131 is provided with a The first wireless headset 140 is placed in the first storage compartment 131 吋 to adapt to the first contact of the first wireless headset 140 audio data; the first storage compartment 131 is provided with a first pass for external conduction Sound hole 133.

[0057] The speaker body 130 is a component of a housing of the speaker, and an acoustic component and a control circuit. The first wireless headset 140 is an earphone that can wirelessly receive an audio signal and transmit an audio signal. The first wireless earphone 140 is composed of a support body connected to an elongated device by a headphone head, and a third contact adapted to the first contact is disposed on the free end or the side wall of the support body; The microphone 141 and its first microphone controller, wireless receiving module, and the like. The first storage compartment 131 is a groove corresponding to the first wireless earphone 140. For example, the first wireless earphone 140 is a left ear, and the shape thereof corresponds to the left earphone, etc., when the first wireless earphone 140 is received in the first After a storage compartment 131, the first contact and the third contact are turned on, thereby realizing data interaction between the wireless earphone and the speaker. During the audio interaction, the speaker can play the audio information received by the first wireless headset 140, the audio signal input by the microphone, and the like. The first acoustic hole 133 is a through hole for conducting the wall of the first storage compartment 131, and may be one or plural. After the first wireless earphone 140 is received in the first storage compartment 131, the first microphone 141 can pick up the sound through the first acoustic hole 133 to improve the sound collecting effect, and form a microphone of the speaker.

[0058] In this embodiment, the speaker further includes a second storage compartment 132 for accommodating the second wireless earphone 150. The second storage compartment 132 is provided with a second contact that is adapted to be exchanged with the audio data of the second wireless headset 150 when the second wireless headset 150 is received in the second storage compartment 132.

[0059] The wireless earphones generally appear in pairs, so the first wireless earphone 140 and the second wireless earphone 150 can be regarded as the left earphone and the right earphone of a set of wireless earphones, then the first storage compartment 131 and the second storage compartment 132 In order to respectively fit the storage compartments of the left earphone and the right earphone, it is convenient for the user to store a set of earphones at the same time. The arrangement in the first storage compartment 131 and the second storage compartment 132 is substantially the same, and a second contact or the like having the same function as the first contact is provided in the second storage compartment 132. In this embodiment, after the first wireless earphone 140 and the second wireless earphone 150 are respectively stored in the first storage compartment 131 and the second storage compartment 132, the microphone attached thereto is not smashed, and only one punch is needed. Generally, the first microphone 141 can be opened. When the first microphone 141 is broken, the second microphone 151 is turned on. Of course, in order to save production cost, only one microphone is set for one wireless headset, that is, the second microphone 151 is not disposed on the second wireless headset 150. If so, the second contact may not be disposed in the second storage compartment 132. . If the second microphone 151 is also provided with a microphone, it is necessary to provide a second contact in the second storage compartment 132. Similarly, the second storage compartment 132 needs to be provided with a second passage for conducting with the outside. Sound hole.

[0060] In this embodiment, only one storage compartment may be disposed, and two storage frames of the same structure are disposed in the storage compartment to fix the first wireless earphone 140 and the second wireless earphone 150 placed in the storage compartment.

[0061] In a specific embodiment, when the two storage compartments of the first storage compartment 131 and the second storage compartment 132 are present, the first sound hole 133 and the second sound hole are in the speaker body 130. After connecting, Unicom has the same sound collecting hole disposed on the speaker body 130. In this way, the first microphone 141 and the second microphone 151 can receive the same sound information, and the audio parameters of the two microphones can be set identically, and need not be separately set, which is convenient to use.

In the speaker box of the embodiment of the present invention, the speaker body 130 is provided with a first storage compartment 131 for accommodating the first wireless earphone 140, and the first storage compartment 131 is provided with a first touch of audio interaction with the first wireless earphone 140. Pointing, the microphone of the first wireless earphone 140 and the speaker can perform audio interaction; the first over sound hole 133 is disposed on the wall of the first storage compartment 131, so that the first microphone 141 in the first storage compartment 131 can be further Good collection of external sound information. It is also possible to provide a second storage compartment 132 or the like which can function the same as the first storage compartment 131.

Referring to FIG. 1 and FIG. 2, an embodiment of the present invention further provides a method for controlling a shared microphone of an audio device, where the audio device includes a first wireless headset 140 and a speaker as described in any of the above embodiments, where The first wireless headset 140 is provided with a first microphone 141; the control method includes the following steps:

[0064] The controller of the first microphone 141 determines whether the first wireless earphone 140 is stored in the first storage compartment 131. [0065] In this step, the controller of the first microphone 141 is an MCU, which stores a corresponding control program, such as a program for controlling a microphone, to implement audio parameter conversion, etc., and performs logical operations to achieve the implementation of the specified function. In this embodiment, the controller of the first microphone 141 can determine whether the first wireless earphone 140 is stored in the first storage compartment 131 by acquiring the designated data.

[0066] S2, if it is determined that the first wireless earphone 140 is received in the first storage compartment 131, the first microphone 141 is controlled to be disposed in the first storage compartment 131 by using a preset suitable for the first microphone 141. The first audio parameter of the collected sound in the sound collection environment.

[0067] In this step, the first storage compartment 131 is generally a semi-closed space, and the sound source inside is mainly the sound picked up by the first over-the-hole 133, so it needs the audio of the first microphone 141. The parameters are adjusted accordingly to ensure the pickup effect of the first microphone 141. The first audio parameter is a parameter for ensuring that the first microphone 141 substantially restores the external sound signal of the storage bin in the first storage compartment 131, and generally performs enhancement processing or the like on the collected sound signal.

[0068] S3. If it is determined that the first wireless earphone 140 is not stored in the first storage compartment 131, the first microphone 141 is controlled to use a preset sound collection environment suitable for the first microphone 141. The second audio parameter of the lower set.
