Embodiment 1
[0026] Such as figure 1 As shown, the active speaker in this embodiment includes a signal input unit, a digital signal processor, a microprocessor, a power amplifier unit and a speaker unit. The digital signal processor is provided with a data storage module, and a group of input processing parameters are stored in the data storage module.
[0027] The set of input processing parameters includes a plurality of entity DSP data (the type of entity DSP data is not limited, and the input processing parameters may contain multiple entity DSP data of the same type, or multiple entity DSP data of different types), each Each entity DSP data contains a speaker layer DSP parameter corresponding to the type of the entity DSP data, and the speaker layer DSP parameter is a DSP parameter set for the active speaker; and at least one entity DSP data also contains a speaker layer corresponding to the speaker Layer DSP parameters are of the same type as array layer DSP parameters, and the arra...
Embodiment 2
[0052] The difference between this embodiment and Embodiment 1 is that in this embodiment, among the DSP data included in the input processing parameters, the DSP data containing the array layer DSP parameters also includes a system layer DSP parameter of the same type as the speaker layer DSP parameter , the system layer DSP parameter is set for each speaker member of the system group to which the active speaker belongs, and the system group includes one or more active speakers.
[0053] The DSP parameters (which may be any type of DSP parameters) used to simultaneously adjust the characteristics of the speaker members of the system group are called system layer DSP parameters, that is, each speaker member of the same system group shares the data of the system layer DSP parameters. If a system layer DSP parameter of a certain speaker member in the system group is modified, the corresponding system layer DSP parameters of other speaker members in the same system group will also...
Embodiment 3
[0058] The difference between this embodiment and Embodiment 1 is that in this embodiment, among the DSP data included in the input processing parameters, at least one DSP data also includes a system layer DSP parameter of the same type as its speaker layer DSP parameter, and the system layer DSP The parameters are set for each speaker member of the system group to which the active speaker belongs, and the system group includes: one or more active speakers.
