[embodiment]

As shown in Figure 1 to Figure 3, the utility model provides a kind of portable CALIBRATION, and it comprises penholder 1 and is installed in tuner assembly 2 in the penholder 1.

Wherein, this penholder 1 is elongate, comprises an intermediate 10 and be arranged in intermediate respectively overlapping 14 in 12 and one end of a top cover at two ends about in the of 10.This top cover 12 and end cover 14 all are connected on the intermediate 10 by means of threaded engagement.Wherein, top cover 12 and the intermediate 10 common containing cavities 16 that form are offered a window 18 on the wall of the chamber of containing cavity 16, these window 18 places also can install the Transparent Parts of a closed window 18, it not only can be protected and be installed in inner element, also can be for observing by this window 18; And formation one cavity (scheming not shown) between end cover 14 and the intermediate 10, and a through hole (scheming not shown) is offered in the bottom at end cover 14, in this cavity, can install pen core 3, pen core 3 is to be installed in versatilely in this cavity, when end cover 14 during towards a certain predetermined direction rotation, the bottom of pen core 3 can be overlapped 14 through hole the end of from and stretch out so that writing function to be provided, and overlaps at the bottom of the reverse rotation 14 o'clock again, and then pen core 3 is withdrawn in the end cover 14 again.The type of the pen core that adopts 3 is not an emphasis of the present utility model, can be various types of refill for ball-point pens, as water-based, oiliness pen core, can adopt versions such as ink barrel that ordinary fountain pen adopts yet.

In addition, tip exterior at penholder 1 also is provided with one for the elasticity folder 4 that is held on the corresponding musical instrument, described elasticity folder 4 is the elasticity folder of opening mode for a kind of pushing, promptly comprise an elastic arm 42 and a briquetting 44, wherein, as shown in Figure 4, the top of this elastic arm 42 is installed in the top of penholder 1 pivotly by means of a pivot 40, and the top of elastic arm 42 also extends to form a butt plate 421, butt has a described briquetting 44 and an elastic component 46 respectively on the both side surface of butt plate 421, and described elastic component 46 can be compression spring, elastic force rubber cushion.And described briquetting 44 is installed in the top of penholder 1, it extends through the roof of penholder 1 top cover 12 and presses on the side surface of butt plate 421 of elastic arm 42 to penholder inside, in preferred implementation of the present utility model, this briquetting 44 is to stretch into penholder 1 inside downwards from the top of penholder 1; Certainly, also can be designed to briquetting 44 is sides that are positioned at penholder 1 top, and it extends laterally the sidewall that passes penholder and stretches into penholder 1 inside, and 421 of the butt sheets of the elastic arm 42 of this moment are the directions that stretch into that are designed to perpendicular to briquetting 44.For preventing that briquetting 44 from splitting away off from penholder 1, and also be provided with barb 441, so that from inboard hook in penholder on 1 the roof in the part that briquetting 44 is positioned at penholder 1 inside.When pressing the briquetting 44 of compression elasticity folder 4, promptly can oppress elastic arm 42 and open, so that be held on CALIBRATION on the musical instrument or on other objects, as shown in Figure 5 around pivot 40 rotations.And when unclamping briquetting 44, under the elastic-restoring force effect of elastic component 46, butt plate 421 is upwards pushed back again, make elastic arm 42 rotations draw in and lean against on the penholder 1.

This tuner assembly 2 is installed in the containing cavity 16 of penholder 1 upper end, comprise that one is used for detecting the music sensing element 20 that music converts the electric current output of corresponding power again to, one pcb board 22 (only is a plate body shown in the figure, and each electronic component on the pcb board does not all draw), be located on the pcb board 22 to receive the electric current that music sensing element 20 transmits and to amplify, detection, export the treatment circuit (its circuit diagram as shown in Figure 6) of corresponding signal after the processing such as filtering and shaping again, one is inserted in the IC chip (as shown in Figure 7) that on the pcb board 22 output signal of treatment circuit is compared judgement, one links to each other with the IC chip and shows the display screen 26 of the frequency height situation of detected music, be located on the pcb board 22 and expose to the switch 28 (its on-off circuit as shown in Figure 8) of penholder 1 outside and the power supply 29 that electric power is provided for each electronic component, extremely shown in Figure 8 as Fig. 6, be respectively treatment circuit successively, the circuit diagram of IC chip and switch, these three circuit diagram respective combination promptly constitute the complete circuit of tuner assembly 2.Wherein, described music sensing element 20 can be a microphone, this moment, the position corresponding to the microphone of its inside offered a miaow hole 160 on the chamber wall of the containing cavity 16 of described penholder 1, during instrument playing, music imports into by microphone from miaow hole 160 and receives, convert current forms to and flow to treatment circuit on the pcb board 22, treatedly compare judgement for the IC chip again; In addition, described music sensing element 20 can also adopt a piezoelectric ceramic piece, and it is close to a side (as Fig. 4 and shown in Figure 5) of being located at pcb board 22, and caused physical vibration is exported corresponding electric current and given treatment circuit during by the induction instrument playing.The display screens 26 that are installed in the containing cavity 16 can be LCD display or LED display, and it is the window 18 on the chamber wall of containing cavity 16 just, observes music frequency status shown on the display screen 26 for the user by this window 18.Because the concrete structure of tuner assembly 2 and principle of work and existing CALIBRATION associated component are basic identical, seldom give unnecessary details at this.

In addition, for understanding the condition information of music frequency more intuitively, can also in described containing cavity 16, also be equiped with the pilot lamp (scheming not shown) of at least one indication accuracy in pitch, when detected pitch is compared with standard value, when frequency is higher or on the low side, this pilot lamp will be lighted, to remind the tuner operator that pitch has deviation, and when detected music frequency is consistent with standard value, then extinguish.

The utility model is integral a CALIBRATION and a common perfect combination, and has the musical instrument tuner simultaneously and write dual-use function, and its good looking appearance, be easy to carry, in use, only need it is clamped in musical instrument, get final product on the qin plate as the sound hole edge of guitar, very easy to use.
