Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] Such as Figure 1-5 Shown is the preferred embodiment provided by the present invention.

[0025] It should be noted that, when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0026] It should also be noted that the orientation terms such as left, right, up, and down in this embodiment are only re...

Abstract

The invention relates to the technical field of stereo equipment and provides a portable wireless charging stereo. The portable wireless charging stereo comprises a main device and an auxiliary device. The main device is provided with a first loudspeaker and a transmitting module, the auxiliary device is provided with a receiving module, a filtering processing circuit, an amplifying circuit and a second loudspeaker; the main device is provided with an induction coil and first positioning blocks, the auxiliary device is provided with an electrified coil, the induction coil and the electrified coil are arranged oppositely, and the main device enables the induction coil and the electrified coil to achieve accurate alignment by the cooperation between the first positioning blocks and the auxiliary device. The transmitting module firstly transmits a wireless signal, the receiving module receives the wireless signal, and then the wireless signal is transmitted to the filtering processing circuit for filtering processing and the amplifying circuit for amplification processing in sequence to enable the second loudspeaker to make low-pitched sound. Accordingly, the portable wireless charging stereo is good in sound quality and good in low-pitched sound. In addition, the main device enables the induction coil and the electrified coil to achieve accurate alignment by the cooperation between the first positioning blocks and the auxiliary device, the induced current is large, the charging effect is good, the power is large, the sound producing effect of the first loudspeaker is good, and the auditory effect is superior.

Description

technical field [0001] The invention belongs to the field of audio equipment, in particular to a portable wireless charging audio. Background technique [0002] At present, the portable wireless charging audio system mainly includes a main unit and an extension unit. The main unit is equipped with a speaker. The power-on principle is to set an induction coil on the main unit and an electrification coil on the extension unit. Coil, in this way, when the energized coil passes through a changing current, correspondingly, the induction coil will generate an induced current for the horn of the host to work and sound. [0003] However, in the process of its actual use, there are still such problems: one, the existing portable portable wireless charging audio system is mainly made by the speaker in the main unit, and the extension only plays the function of charging the main unit, and in order to achieve the purpose of portability , the host is usually small in size, the speaker c...
