本申请涉及声音播放技术领域，具体涉及一种响度调节方法、装置、存储介质及电子设备。The present application relates to the field of sound playback technology, and in particular to a loudness adjustment method, device, storage medium and electronic device.
背景技术Background technique
在现代家庭娱乐中，双设备使用场景越来越普遍，双设备使用场景存在第一设备(如电视)和第二设备(如Sound bar)协同播放相同音频(通常是第一设备中提供的音频)的共播场景。In modern home entertainment, dual-device usage scenarios are becoming more and more common. Dual-device usage scenarios include a co-broadcast scenario in which a first device (such as a TV) and a second device (such as a sound bar) collaboratively play the same audio (usually the audio provided in the first device).
在共播场景下，虽然第一设备(如电视)和第二设备(如Sound bar)协同发声能够带来更好的听感，但容易存在响度不均衡问题，会导致用户的听感不佳。而针对响度不均衡的问题，目前现有的解决方案通常为由人工测量响度进行手动调整或者简单地根据设备距离进行响度自动调节。In the co-broadcasting scenario, although the coordinated sound generation of the first device (such as a TV) and the second device (such as a sound bar) can bring a better listening experience, there is a problem of uneven loudness, which will lead to poor listening experience for users. To address the problem of uneven loudness, the current existing solutions are usually to manually measure the loudness and make manual adjustments, or simply automatically adjust the loudness according to the distance between the devices.
但是，目前的方式下，通常存在双设备共播场景下设备响度均衡效果较差的问题，用户体验较差。However, under the current method, there is usually a problem of poor device loudness balancing in the scenario of dual-device co-broadcasting, which leads to poor user experience.

The execution subject of the loudness adjustment method can be any device or server with processing capabilities, such as a TV, a computer, a mobile phone, a smart watch, and a home appliance, and the server is a cloud server or a physical server.
本申请的一种具体实施例中，该响度调节方法的执行主体具体为设备，该设备可以是第一设备或第二设备中一个，该设备也可以是第一设备或第二设备之外的其它设备(例如用户持有的手机等等)。In a specific embodiment of the present application, the execution subject of the loudness adjustment method is specifically a device, which can be one of the first device or the second device, or can be another device other than the first device or the second device (such as a mobile phone held by a user, etc.).
如图1所示，该响度调节方法可以包括步骤S110至步骤S140。As shown in FIG. 1 , the loudness adjustment method may include steps S110 to S140 .
步骤S110，检测第一设备中扬声器与麦克风之间的第一距离、所述第一设备中麦克风与第二设备之间的第二距离、所述第一设备的麦克风接收本端播放声音的第一响度及接收所述第二设备所播放声音的第二响度；步骤S120，根据所述第一距离与所述第二距离进行计算，得到所述第二设备中扬声器相对于所述第一设备中扬声器的响度衰减值；步骤S130，根据所述第一响度、所述第二响度及所述响度衰减值进行计算，得到所述第二设备中扬声器的响度调整值；步骤S140，根据所述响度调整值在共播场景中对所述第二设备进行响度均衡调整，其中，所述共播场景中所述第一设备与所述第二设备协同播放相同音频。Step S110, detecting a first distance between a speaker and a microphone in a first device, a second distance between the microphone in the first device and a second device, a first loudness of the microphone of the first device receiving a sound played locally, and a second loudness of the microphone of the first device receiving a sound played by the second device; Step S120, calculating according to the first distance and the second distance to obtain a loudness attenuation value of the speaker in the second device relative to the speaker in the first device; Step S130, calculating according to the first loudness, the second loudness, and the loudness attenuation value to obtain a loudness adjustment value of the speaker in the second device; Step S140, performing loudness equalization adjustment on the second device in a co-broadcasting scenario according to the loudness adjustment value, wherein the first device and the second device in the co-broadcasting scenario collaboratively play the same audio.
在双设备共播场景下，针对第一设备和第二设备可以进行相关检测，通过检测可以获得第一距离、第二距离、第一响度及第二响度。In a dual-device co-broadcasting scenario, relevant detection may be performed on the first device and the second device, and the first distance, the second distance, the first loudness, and the second loudness may be obtained through the detection.
第一距离为第一设备(例如电视)中扬声器与麦克风之间的距离，第二距离为第一设备(例如电视)中麦克风与第二设备(例如回音壁)之间的距离。The first distance is the distance between the speaker and the microphone in the first device (eg, a TV), and the second distance is the distance between the microphone in the first device (eg, a TV) and the second device (eg, a sound bar).
第一响度为第一设备的麦克风接收到本端播放声音(也即第一设备的扬声器播放声音)时第一设备的麦克风处的响度。第二响度为第一设备的麦克风接收到第二设备所播放声音时第一设备的麦克风处的响度。The first loudness is the loudness at the microphone of the first device when the microphone of the first device receives the sound played by the local end (that is, the sound played by the speaker of the first device). The second loudness is the loudness at the microphone of the first device when the microphone of the first device receives the sound played by the second device.
根据第一距离与第二距离进行计算，可以得到第二设备中扬声器相对于第一设备中扬声器的响度衰减值，该响度衰减值可以反映第一设备和第二设备当前的位置分布下第二设备中扬声器相对于第一设备中扬声器的响度衰减程度。By calculating based on the first distance and the second distance, a loudness attenuation value of the speaker in the second device relative to the speaker in the first device can be obtained. The loudness attenuation value can reflect the degree of loudness attenuation of the speaker in the second device relative to the speaker in the first device under the current position distribution of the first device and the second device.
根据第一响度、第二响度及响度衰减值进行计算，得到第二设备中扬声器的响度调整值，根据该响度调整值在共播场景中对第二设备进行响度均衡调整(具体可以将第二设备的响度增加响度调整值)，即可有效实现双设备共播场景下设备响度均衡，该共播场景中第一设备与第二设备协同播放相同音频。A calculation is performed based on the first loudness, the second loudness, and the loudness attenuation value to obtain a loudness adjustment value of the speaker in the second device. The loudness equalization of the second device is adjusted based on the loudness adjustment value in the co-broadcasting scenario (specifically, the loudness of the second device can be increased by the loudness adjustment value). This can effectively achieve device loudness equalization in a dual-device co-broadcasting scenario, in which the first device and the second device collaboratively play the same audio.
以这种方式，基于步骤S110至步骤S140，在双设备共播场景下，通过检测第一距离、第二距离、第一响度及第二响度，根据第一距离与第二距离计算第二设备中扬声器相对于第一设备中扬声器的响度衰减值，以及，根据第一响度、第二响度及响度衰减值计算得到第二设备中扬声器的响度调整值，来在共播场景中对第二设备进行响度均衡调整，可以使得双设备共播场景下第一设备和第二设备的响度有效均衡，有效提升双设备共播场景下设备响度均衡效果，提升用户体验。In this way, based on steps S110 to S140, in a dual-device co-broadcasting scenario, by detecting the first distance, the second distance, the first loudness, and the second loudness, calculating the loudness attenuation value of the speaker in the second device relative to the speaker in the first device according to the first distance and the second distance, and calculating the loudness adjustment value of the speaker in the second device according to the first loudness, the second loudness, and the loudness attenuation value, the second device is adjusted for loudness balance in the co-broadcasting scenario, so that the loudness of the first device and the second device in the dual-device co-broadcasting scenario can be effectively balanced, effectively improving the device loudness balance effect in the dual-device co-broadcasting scenario, and improving the user experience.
