Abstract

The utility model relates to a portable book type piano which is formed by that the upper part of the opened portable book type piano is bound with book pages with pictures and songs, the lower part of a bottom page is provided with a bottom seat with a clamping block, a printing circuit board with an integrated circuit, batteries and a piano keys touch switch and a buzzing sheet are arranged on the bottom seat, an upper cover is buckled on the bottom seat, the piano keys labeled with musical scale symbols are exposed outside, different RC built-in oscillation is formed by different musical scale, and a book with different sounding musical qualities and tone can be made after the different RC built-in oscillation is processed. The portable book type piano is provided with songs and pictures and can be played.

Description

Portable book type piano

The utility model relates to the picture album of having the amusement effect in human lives's needs.

Existing children's book equipped, it mostly is the noiseless reading matter of on paper, publishing literal or having the aesthetic feeling colour image, Chinese patent CN87104908 disclosed " picture book with entertainment effect " also is the specific picture book and the layout of corresponding game element combination thereof; Existing toy piano price comparison costliness, it is longer that keyboard is pressed down stroke, and list will occupy more space, and children play and also produce certain difficulty.

The purpose of this utility model is to make a kind of portable books piano that has children's song collection of tunes of poems, has the song content picture, can carry out the song performance.

One-piece construction of the present utility model as shown in Figure 1.

Open the top 1 of back books piano, according to the method for stitching of general books, be added with cord 2 between the page, the top page or leaf 3 of page and end page or leaf 4 stick on the books inboard of front cover up and down by binding.The recto of book page sheet, be printed with song collection of tunes of poems of a collection of selected materials, the verso of book page sheet, be printed with the colour pitcture of expressing the song content of selecting and compile, the page or leaf bottom, the end 5 of books piano, the base 6 of band fixture block is installed, have integrated circuit 7, battery 8, the printed circuit board (PCB) 10 of key soft-touch control 9 and piezo 11 that can sounding are placed within the base 6 that has fixture block, the lower end has anti-the pressure and supports fixture block, there is the loam cake 12 of opening at corresponding piezo 11 places, be fastened on the base 6 that has fixture block, the key soft-touch control 9 that makes 10 of printed circuit board (PCB)s leave sign scale symbol is exposed.

Circuit square frame of the present utility model as shown in Figure 2;

Electric principle wiring of the present utility model as shown in Figure 3.

Two 1.5 volts button cell 8 provides working power for integrated circuit 7, and the different scale positions of touch key soft-touch control 9 constitute the different built-in oscillation frequency of integrated circuit 7RC oscillator, arranges by adjusting, and forms the series standard scale.The user can carry out association, carry out the touch performance according to being printed on each note and identification colors mark according to the colour pitcture that is printed on song content, also can indiscriminately ad. as one wishes carry out touch and play, hear melodious music according to the song note beat of oneself being familiar with.

Integrated circuit 7 adopts M3522 or HM5601,39K Ω is the peripheral resistance of RC oscillatory circuit, touch key soft-touch control 9, the logical integrated circuit 7 different oscillation frequency outputs of structure also make piezo 11 sounding, decontrol the key soft-touch control, with regard to the power supply of the automatic sever supply integrated circuit 7 of energy, the electrical source consumption when having avoided not sounding generally can use button cell 1 year.

The utility model makes noiseless music textbook increase the function of sounding, can be used for teaching and collective and play, and the user also can carry out self-bullet and sing exercise, cultivates musicianship, encourages mental the growth.The books piano is the inboard fastening of front cover up and down, then forms books easy to carry.

The utility model can and cooperate R, L, C element to polish according to the height of integrated circuit 7 oscillation frequency, touch the sound of various musical instruments such as imitative piano, clarinet, oboe, organ, flute, trumpet, saxophone, sheng, a reed pipe wind instrument, make the books of different sounding tone colors and tone.

Base 6 and loam cake 12 adopt the plastics compacting to form, and the fixture block top that base 6 attaches is big slightly, and be closely connected fastening when loam cake 12 is fastened with its.
