Description

Portable low frequency music massage cushion

Technical field

The invention relates to a cushion, in particular to a portable low-frequency music massage cushion which is small in size, convenient to carry, and can effectively combine music and massage synchronously.

Background technique

There are many products such as music massage cushions for people to use in order to eliminate fatigue. However, the disadvantages are as follows: 1. Some products only use the motor massage component to fix the frequency. The frequency range of the music rhythm output by the speaker is wide, and there is no correlation between the vibration frequency of the motor massage component. 2. Some use the low frequency sound to drive the vibrator. The massage principle is achieved, but the audio machine and the power amplifier are separately designed and used, resulting in a large product, that is, the audio machine is connected to the power amplifier, and the output end of the amplifier is electrically connected to the vibrator, and the vibrator is built in a special large mattress. This structure is suitable for large massage instruments and cannot be popularized to ordinary modern people. 3. The audio of existing music massage products is generally a separate MP3, radio, radio, CD player, VCD player, DVD player and other audio equipment. It is necessary to connect various terminal wires during installation, which is not convenient to carry around.

Summary of the invention

In order to overcome the shortcomings of the prior art, the present invention aims to provide a portable low-frequency music massage cushion which has a simple structure, can be repeatedly used for a rechargeable battery, and has different colors and products that automatically enter the water to work.

The invention is realized by the following technical measures, a portable low-frequency music massage cushion, comprising a cushion body, wherein at least one music horn is disposed in a side of the cushion body, and a vibration horn is disposed in the back of the cushion body, the cushion a PCB board and a battery are also disposed in the side of the body, and the sound is disposed on the PCB board The frequency playing circuit and the power amplifying circuit send the audio information to the music horn, and the power amplifying circuit filters the audio information by 20-100 Hz and then transmits the signal to the vibration horn.

As a preferred mode, the music horn is a pair symmetrically disposed on two sides of the pad body.

As a preferred manner, a Bluetooth module is further disposed on the PCB.

As a preferred mode, the battery is a rechargeable lithium battery.

As a preferred manner, a cushion cover is further disposed on the outer surface of the pad.

In a preferred embodiment, the pad body is further provided with an NFC tag, and the NFC tag stores a link of a music playing website.

The invention can eliminate the fatigue by using the music and the vibrating horn synchronized with it in the work of modern people; the invention designs the audio playing circuit and the power amplifying circuit on the same PCB board, and can be applied to any small small family. The use of the cushion, the power amplifier circuit of the somatosensory vibrating horn, adds a low-frequency signal circuit portion, mainly composed of a low-pass filter circuit, a protection circuit and a low-frequency signal amplifier, and the input audio signal is subjected to high-frequency filtering through a multi-stage low-pass filter, and then The low frequency signal is amplified and output, and the low frequency signal is formed in a frequency range of 20 Hz to 100 Hz, so that the transducer forms a stable mechanical vibration effect, so that people can feel the corresponding vibration while enhancing the music while enhancing the perception and enjoyment. The function of the massage product is enhanced. The invention effectively combines music and massage better, is small in size, and is better suited to the family.

Detailed ways

The present invention will be further described in detail below with reference to the embodiments and with reference to the accompanying drawings.

A portable low-frequency music massage cushion, with reference to FIG. 1 to FIG. 3, includes a cushion body 1 , at least one music horn 2 is disposed in a side of the cushion body 1 , and a vibration horn 4 is disposed in the back of the cushion body 1 . The side of the pad body 1 is further provided with a PCB board and a battery 3, and the PCB board is provided with an audio playing circuit and a power amplifying circuit, and the audio playing circuit sends the audio information to the music horn 2, the power amplification The circuit filters the audio information by 20-100 Hz and transmits it to the vibrating horn 4 by amplification.

The massage cushion can relax the fatigue of the modern people, using the music and the vibrating horn synchronized with it to achieve the purpose of eliminating fatigue; the massage cushion design the audio playback circuit and the power amplifier circuit on the same PCB board, which can be applied to ordinary families. Any small cushion used, the power amplifier circuit of the somatosensory vibrating horn increases the low-frequency signal circuit part, mainly composed of a low-pass filter circuit, a protection circuit and a low-frequency signal amplifier, and the input audio signal is subjected to high-frequency filtering through a multi-stage low-pass filter. Then, the low-frequency signal is amplified and output, and the low-frequency signal is formed in a frequency range of 20 Hz to 100 Hz, so that the transducer forms a stable mechanical vibration effect, so that people can feel the corresponding vibration while enjoying the music, and enhance the perception and enjoyment. The function of the massage product is enhanced. This massage cushion effectively combines music and massage, and is small in size and better suited for families.
