BACKGROUND OF THE INVENTION

A speaker is a device that converts an audio signal into sound. In general, it means that the main body or the subwoofer box of the speaker has its own power amplifier to amplify the audio signal, and after the amplification, the speaker played back the sound, making the sound louder. The speaker is the terminal of the entire sound system, and its function is to convert the audio energy into the corresponding sound energy and radiate it into the space. The speaker is an extremely important part of the sound system, and it is responsible for the task of converting an electrical signal into an acoustic signal for a human ear's direct listening.
In the prior art, the combination speakers are mostly two separate boxes, which cannot be combined, or can be combined by magnet adsorption, but are not convenient to be carried to outdoor for use. The prior art cannot solve a problem that a speaker could give consideration to both of the indoor desktop use and the outdoor portable use. In order to solve the above problem, the present application has devised a detachable combination speaker.
US 2018/234768 A1 discloses a speaker system including two speaker units, each including: a waterproof shell, a front vertical side of which defining a sound opening passing therethrough; a magnetic base at the bottom of the shell configured to hold together the speaker units when the magnetic bases of the two speaker units are placed together, the front vertical side of each will point in a common direction; a rechargeable battery within the shell; a speaker adjacent the sound opening; and an electronic circuit that communicates with the wireless device and demodulates the wireless signal to drive the speaker. A flexible protective covering has a shape that is complimentary in shape to the two speakers when the two speakers are held together at the magnetic bases. The flexible protective covering holds the two speakers together therein.
WO 2015/103312 A1 discloses interchangeable speaker enclosures (or "jackets"). The jackets can protect a portable speaker from potential damage resulting from moving the speaker, which can be moved around indoors or used outdoors. Jackets can be easily attached to the portable speaker and easily detached from the portable speaker. Jackets can provide aesthetic appeal and protect the speaker from damage, while improving the quality of audio output and enhancing the listening experience.
