Abstract

The utility model relates to a pen, comprising an outer case and a pen core installed in the internal cavity of the outer case. The utility model is characterized in that a music circuit is arranged in the internal cavity of the outer case, the music circuit is composed of a battery, a music integrated block and a trumpet, an anode and a cathode of the battery respectively connects with the power supply end and the earth end of the music integrated block, the trumpet connects with the signal output end of the music integrated block and the triggering pin of the music integrated block is connected with a triggering switch. The whole music device is installed in the internal cavity of the outer case, the external appearance of the pen is not influenced and the pen has two functions of a pen and entertainment.

Description

Pen with music device

The utility model relates to a kind of pen.

Pen of the prior art is made up of shell and pen core, and pen core comprises that its functions such as refill for ball-point pen and pen core are comparatively single.

The purpose of this utility model is to provide a kind of pen that can send music.

The technical solution of the utility model is: the utility model comprises the pen core in shell and the cased chamber, also be provided with music circuit in the shell inner cavity, this music circuit is made up of battery, music-integrating block, loudspeaker, the both positive and negative polarity of battery is connected on the power end and the earth terminal of music-integrating block respectively, loudspeaker connect the signal output part of music-integrating block, are connected to trigger switch on the triggering pin of music-integrating block.When pressing trigger switch, music-integrating block makes loudspeaker send musical sound.Described music circuit comprises can send the circuit that music maybe can be sent language.

The utlity model has following advantage:

Whole music apparatus is installed in the shell inner cavity, does not influence the outward appearance of pen, and the utlity model has pen and amusement two purposes.

Accompanying drawing 1 is the structure cutaway view of an embodiment of the present utility model;

Wherein: 1. loudspeaker; 2. integrated package; 3. battery; 4. the pen cap; 5. pen core; 6. penholder;

Accompanying drawing 2 is the circuit theory diagrams of music circuit of the present utility model (integrated package 2);

Accompanying drawing 3 is the circuit theory diagrams of language circuit of the present utility model (integrated package 2);

Embodiment, referring to accompanying drawing 1, this embodiment mainly comprises the pen cap 4 and penholder 6, and two pieces of button cells 3 are housed in the cavity of the pen cap 4, and music-integrating block 2 or language integrated package are installed in the inner chamber above battery 3, loudspeaker 1 are equipped with on the top of the pen cap 4.Penholder 6 is formed by being threaded by two parts up and down, and refill for ball-point pen 5 is housed in its inner chamber, also pen core or pencil-lead can be installed.The trigger switch of music-integrating block protrudes from outside the shell.Also can adopt the trigger switch of vibroswitch as music-integrating block, this vibroswitch is arranged in the inner chamber of shell.Shell in the technical scheme refers to the housing of pen core 5 outsides, can be penholder part or pen cap part.Referring to accompanying drawing 2, the model of IC 1 is KD-9300, TR1 is the triggering pin of this integrated package, VDD is a power pins, and VSS is an earth terminal, and BG1 is the power amplification triode, S1 is loudspeaker, after the trigger switch of TR1 pin was pressed, the signal output pin output signal of telecommunication by IC1 sent musical sound by loudspeaker S1 after power discharging transistor BG1 power amplification.Referring to accompanying drawing 3, the model of IC 2 is MSS0602, is a language integrated circuit, and VDD is a power end, and VSS is an earth terminal, and Voutl is a language signal of telecommunication output pin, and BG2 is the power amplification triode, and S2 is loudspeaker.

Claims
