Description

Connectable speakers

technical field

The utility model relates to a speaker device which is convenient to adjust and can work individually or in series.

Background technique

There are many kinds of traditional speakers, mostly two or more speakers are connected and paired with wires. However, the fixed wires will limit the range of speaker placement, and it is not convenient to move frequently to avoid damage to the wires or entanglement of the wires during pulling. Therefore, someone has developed related products.

For example, Patent Document 1 is the "Improved Structure of Portable Horn" of Taiwan Patent Certificate No. M289948, which was announced on April 21, 2006. This patent document records an improved structure of a portable speaker, which mainly includes: a small sound box , a small speaker and a built-in amplifier are arranged on it; and a foldable wire, which is short-cut and can be positioned according to folding deformation, one end is provided with a connector, and the other end is connected to the small speaker, thereby making the assembly The speakers that can be planned are small in shape, easy to carry and plug in, and can be folded and reversed at will.

As another example, patent document 2 is the "combined audio playback device" of Taiwan Patent Certificate No. M293492, which was announced on January 1, 2006. This patent document discloses a combined audio playback device, which includes a A host and a plurality of first loudspeakers, the host includes a casing, a circuit board disposed in the casing, and an audio output port disposed in the casing and electrically connected to the circuit board, each first loudspeaker includes A housing, a winding unit, a transmission line, an adapter unit and a playback unit electrically connected to the adapter unit, one end of the transmission line is electrically connected to the adapter unit, and the other end includes a The audio output port is electrically connected to the audio input port. The line segment of the transmission line connector can be wound around the winding unit to be stored in the housing in the storage state, and can be pulled out of the housing in the use state, and can be adjusted Pull out the length to place the main unit and the first speaker at an appropriate distance.

In the improved structure of the portable speaker in Patent Document 1, the speaker does not have the function of serial connection, and must rely on a device electrically connected to the speaker, such as a computer, to provide broadcasting and light-emitting drive. Therefore, if several speakers can be connected in series, the distance between the speakers can be reduced. Spread out the arrangement for a surround sound playback effect.

And the problem that patent document 2 exists is that the loudspeaker of this combined audio playback device must be electrically connected with the host, and the host must also be electrically connected with a storage device to play voice and music, so the loudspeaker must also be used with the host to obtain playback. The driver cannot be used alone, that is, it lacks the convenience of use. Therefore, if it can be directly electrically connected with the storage device and self-supplied to work alone or in series, the limitation on use can be reduced.
