摘要： This application provides a combination phase plug, and a compression driver and a speaker using same. The combination phase plug of this application includes a first phase plug and a second phase plug. The second phase plug is located under the first phase plug. The first phase plug includes a cone, a plurality of first fins, and a plurality of second fins. The first fins and the second fins are located on an outer surface of the cone in a staggered manner. A first gap exists between any first fin and a second fin adjacent to the first fin. The second phase plug includes a round-disc base, a combining portion, and a plurality of second gaps. The combining portion is located in the center of the round-disc base and the combining portion and the cone can be combined with each other. The second gaps are located between an outer edge of the round-disc base and the combining portion. The first gaps are respectively aligned with the second gaps to form a plurality of channels to improve the acoustic performance.

摘要： A motion inducing system for playing sounds over a gramophone is provided. An electrical signal such as that from a digital music player is converted to lateral movement of a surface using a linear motion transducer. The lateral movement moves the stylus of a gramophone, and the music from the digital music source is played through the horn of the gramophone.

摘要： This disclosure relates to speakers and more specifically to an array speaker for distributing music uniformly across a room. A number of audio drivers can be radially distributed within a speaker housing so that an output of the drivers is distributed evenly throughout the room. In some embodiments, the exit geometry of the audio drivers can be configured to bounce off a surface supporting the array speaker to improve the distribution of music throughout the room. The array speaker can include a number of vibration isolation elements distributed within a housing of the array speaker. The vibration isolation elements can be configured reduce the strength of forces generated by a subwoofer of the array speaker.
