Description

amplified harmonica

technical field

The utility model belongs to the field of melodic musical instruments and relates to a sound-enhancing harmonica.

Background technique

Harmonica is a kind of musical instrument commonly used in stage performances. It is a multi-reed musical instrument that makes metal reeds vibrate and sound by blowing or inhaling with the mouth. It belongs to the free-reed wind instrument in the classification of musical instruments. Since the sound source is a reed with a length of 1.5 to 3.5 cm rather than an air column (such as a flute), it is mainly divided into a solo harmonica and an ensemble harmonica. As a melodic instrument, the harmonica can play at least two kinds of chords, and high-level players can play two relatively independent voices at the same time on the premise that the harmonica follows the structure of the harmonica. But the volume that the harmonica blows out is limited, and in some performance occasions, only the audience who is close can hear clearly, and the audience who is far away can hear the sound less. In addition, during the practice period, looking at the Lepu on the cardboard is a boring thing. For beginners and children, it is easier to get sleepy and affect the learning efficiency.

Utility model content

In order to solve the above technical problems, the utility model provides an amplified harmonica.

The utility model is realized through the following technical solutions.

A kind of amplified harmonica provided by the utility model comprises LED display screen, pull rod, upper spring plate, cover plate, qin grid, lower spring plate, seat plate and loudspeaker, and described qin grid is clipped on upper spring plate and Between the lower spring plates, the cover plate is installed on the outer side of the upper spring plate, the seat plate is installed on the outer side of the lower spring plate, the lower part of the LED display screen is provided with a sleeve, the middle part of the pull rod is assembled with the sleeve tube, and the two ends of the pull rod The end is connected with the fretboard, and the loudspeaker is inlaid under the LED display screen.

The pull rod is a U-shaped structure.

The part of the pull rod between the LED display screen and the fret is made in the form of a tube in a tube.

The material of the fret is plastic or wood.

The upper spring plate and the lower spring plate are provided with blowing reeds and sound-absorbing reeds arranged at intervals.

The upper spring plate, cover plate, fretboard, lower spring plate and seat plate are connected by screws.

The grid is provided with grids corresponding to the blowing reed and the sound-absorbing reed.

Both ends of the fret are respectively provided with a battery hole and a USB interface.

The beneficial effect of the utility model is that: the utility model can increase the music volume when the harmonica is played, and at the same time, the music score can be displayed through the LED display screen, avoiding the boring feeling brought by the cardboard score, improving the learning fun of beginners and children, and facilitating them Recite sheet music. You can also blow while watching the electronic LED display screen to improve learning efficiency.

detailed description

The technical solution of the utility model is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.

As shown in Figure 1, a kind of amplified harmonica, comprises LED display screen 1, pull rod 2, upper spring plate 3, cover plate 4, qin grid 5, lower spring plate 6, seat plate 7 and loudspeaker 8, described The fret 5 is clamped between the upper spring plate 3 and the lower spring plate 6, the cover plate 4 is mounted on the upper spring plate 3, the seat plate 7 is mounted on the lower spring plate 6, and the lower part of the LED display screen 1 is provided with There is a sleeve, the middle part of the pull rod 2 is assembled with the sleeve, the two ends of the pull rod 2 are connected with the fret 5, and the loudspeaker 8 is embedded under the LED display screen 1 .

The two ends of the fret 5 are respectively provided with a battery hole 51 and a USB interface 52, the battery is installed on the battery hole 51, and the battery is connected with the LED display screen 1 and the loudspeaker 8 by wires. And the score is made on the computer with the software attached to the LED display screen, then downloaded to the USB flash drive, the USB flash drive interface is inserted in the USB interface 52, and the score can be displayed on the LED display screen 1. The middle part of the pull rod 2 is assembled with the casing provided on the LED display screen 1, and the matching gap is 0.02 to 0.03 mm, so that the LED display screen 1 can rotate on the pull rod 2 without slipping down to adjust the position of the LED display screen 1. Location for easy viewing.

The pull rod 2 is a U-shaped structure, so that the two ends of the pull rod 2 are used to connect the fret 5 .

The part of the pull rod 2 between the LED display screen 1 and the fret 5 is made in the form of a sleeve in a tube, so that the pull rod 2 can be retracted or stretched out, and the storage space can be reduced when retracted, and can be enlarged when stretched out. The distance between the LED display screen 1 and the eyes is beneficial for the eyes to watch without hurting the eyes.

The material of the fret 5 is plastic or wood, so as to reduce weight and insulate.
