Description

wall background music controller

technical field

The utility model relates to a small constant-resistance power amplifier used in audio signal transmission, in particular to a small switchboard-type background music controller embedded in the wall of a family house to regulate the audio output signal.

Background technique

With the continuous improvement of people's living standards and quality of life, music has become an indispensable part of some people's lives. So people have invented portable radio recorders, mini CD players, and MP3 players that have appeared in recent years. These electronic products for playing music are really very convenient for people to appreciate music, and users can listen to music anytime no matter where they go. But these products all have a common characteristic promptly must put on earphone when listening to music. In contrast, although the background music played in hotels, nursing homes, and leisure and entertainment places can get rid of the shackles of headphones, it cannot be adjusted by individuals as they wish. Can the two be combined, not only free from the shackles of the earphones but also can be regulated by individuals, so that you can listen to music freely at home and do other things at the same time, this is the applicant's original intention of inventing the utility model .

Utility model content

The purpose of the utility model is to provide an adjustable background music controller for playing at home, which can listen to music and adjust the volume in every room of the house. It can get rid of the shackles of having to wear earphones when listening to music with a mini radio, CD player or MP3 player, so that people who go home after a tiring day can fully relax and enjoy the spiritual bath of background music.

The technical scheme of the utility model to solve the technical problem is: install this controller in each room of the home, and connect it with the original audio system, the volume can be individually adjusted or turned off in each room, and the background sound can be listened to in all rooms of the home. music. The controller is composed of a panel, a base, a circuit board, and also includes a switch and volume adjustment knob, a potentiometer and a micro-transformer. The panel is square and has the same specifications as the panel of the 86 series wall-type electrical switch and socket. There is a mounting screw hole at each of the four corners of the panel, and a cover plate covers the outside; There is a red power indicator light; in the middle of the lower part of the panel are three arc-shaped LED indicators and a timing button. Press once for 15 minutes, press twice for 30 minutes, and press three times for 60 minutes. The arc-shaped LED indicates The lights are switched accordingly; there is an MP3 jack on the lower side of the panel. The circuit board, potentiometer and miniature transformer are arranged on the back of the panel, and are fixed behind the panel with fastening screws. The base is a small square box, and a concave step is arranged on the outside of the upper part, and a power input terminal, an audio signal output and a sound source input terminal are arranged. Fastening screws are also used to securely connect the base and the panel. The circuit board is provided with micro-transformers, potentiometers and electronic components, which form circuits such as rectification, voltage stabilization, reset, timing, switches, audio source input, volume adjustment, power amplification, and audio output. Or CD player, etc. constitute a complete background music playback system.

The utility model is exquisitely designed, and can be embedded in the wall for installation, and the bottom box installed in the utility model is common to the bottom box of the common electrical socket. It is not only suitable for home use, but also suitable for installation and use in hotel boxes, bars, hotel rooms, hospitals, and senior wards of nursing homes.

Detailed ways

Now with reference to the accompanying drawings, the utility model will be further described in detail: as shown in Figures 1 to 3, the utility model is composed of a panel 1, a base 12, a circuit board 7, and also includes a switch and a volume adjustment knob 3, a potentiometer 15 and Microtransformer8. Described panel 1 is square, is identical with the panel specification of 86 series wall-mounted electric switches and sockets, is provided with switch and volume adjustment knob 3 in the middle of front upper part, and knob is fixedly connected with the rotating shaft of potentiometer 15 protruding from panel 1 back side. In the middle of the panel 1 bottom is a timing switch button 5, and three arc-shaped LED timing indicator lights 4 are arranged around the timing switch button 5, and represent 15, 30 and 60 minutes respectively; The circuit board 7 and the microtransformer 8 are arranged on the back of the panel 1, and are fixed on the back of the panel 1 with fastening screws 14. The base 12 is a small square box, the upper part of which is provided with a concave step on the outside, on which a sound source input terminal 11 , an audio signal output terminal 10 and a power input terminal 11 are arranged. Fastening screws 14 are also fixedly connected between the base 12 and the panel 1 . Micro-transformer 8, potentiometer 15 and electronic components are arranged on the circuit board 7 to form circuits such as rectification, voltage stabilization, reset, timing, switch, audio source input, volume adjustment, power amplifier, output, etc., and they are connected with external audio, MP3 or CD player and so on constitute a complete background music playback system.

During installation, remove the cover plate 2, fix the panel 1 on the bottom box pre-buried in the wall, connect the power input terminal 11 with the mains, connect the signal output line of the VCD player to the audio input terminal 9, and connect the audio The signal output terminal 10 is connected with the audio line at home, and after the connection is fixed, the cover plate 2 is covered to form a family background music playing system. If the power amplifier has been installed originally, a transfer switch can be set in the middle. During use, the MP3 player or CD player is inserted into the MP3 socket 13, and the rotary switch and the volume adjustment knob 3 drive the potentiometer 15 to play background music and adjust the volume.
