Description

Harmonica The present invention relates to a harmonica, and more specifically, to a harmonica in which sound collection performance for each pitch range is improved by placing piezo microphones of different sizes at optimal positions according to the pitch generated from the reed plate of the harmonica. Generally, when using piezo microphones for the electrical sound collection of a harmonica, a structure in which piezo microphones of the same size are uniformly distributed across the entire reed plate has been primarily used. This conventional structure has the following problems: First, although the pitch generated by the harmonica's reed plate varies depending on the position and the vibration characteristics and volume differ for each pitch range, there is a problem in that the characteristics of each pitch range are not properly reflected due to the use of piezo microphones of the same size. Second, particularly in the low frequency range, the reed is long and thick, causing slow vibration and resulting in weak sound intensity; however, an appropriate sound-collecting structure to compensate for this was not provided. Third, although sufficient sound collection is possible with small microphones in the high-frequency range, using large microphones resulted in problems such as distorted high-frequency sounds or the mixing of sounds from adjacent frequency ranges, leading to a degradation in sound quality. Fourth, as the piezo microphones were installed without systematic consideration of the spacing or placement location between them, interference occurred between the microphones, and as a result, there was a problem in that it was difficult to obtain accurate acoustic signals. (Patent Document 1) KR 10-2022-0130816 A Figure 1 is a diagram showing the usage state of a harmonica with a built-in microphone of the present invention and a wireless signal transmitter connected thereto. Figure 2 is a drawing for explaining the internal configuration of a harmonica with a built-in microphone according to the present invention. Hereinafter, the present embodiment will be examined in detail with reference to the accompanying drawings. However, the scope of the inventive concept of the present embodiment may be determined from the matters disclosed in the present embodiment, and the inventive concept of the present embodiment shall be understood to include variations in implementation such as the addition, deletion, or modification of components with respect to the proposed embodiment. The suffixes "module" and "part" used in descriptions related to the present invention are assigned or used interchangeably solely for the ease of drafting the specification, and do not inherently possess distinct meanings or roles. FIG. 1 is a diagram showing the usage state of a harmonica with a built-in microphone of the present invention connected to a wireless signal transmitter, and FIG. 2 is a diagram explaining the internal configuration of a harmonica with a built-in microphone of the present invention. The harmonica of the present invention includes a function that enables louder and more accurate sound to be emitted through an external speaker by incorporating a microphone. In a performance venue, there is no need to install a separate microphone near the performer due to the harmonica's quiet sound. In particular, the microphone mounted inside the harmonica is composed of piezo microphones of different sizes corresponding to the pitch of the harmonica, thereby enabling the output of an even sound by incorporating a microphone corresponding to the pitch of the harmonica. Referring to FIGS. 1 and 2, a wireless signal transmitter (300) for wirelessly transmitting sound received by microphones inside the harmonica (100) to another external speaker may be connected to the harmonica (100), and an intermediate cable (200) connecting the harmonica (100) and the wireless signal transmitter (300) may be further configured. To this end, the body of the harmonica (100) may be configured with a female microphone jack (110) into which the male jack of the intermediate cable (200) can be inserted, and a female power jack (120) may be further configured to supply power to an LED unit (140) configured in the harmonica (100) together with the female microphone jack (110). When the intermediate cable (200) and the wireless signal transmitter (300) are connected through the female microphone jack (110), the piezo microphones are operated using power supplied from the wireless signal transmitter (300). As illustrated in FIG. 2, the harmonica (100) of the embodiment includes a reed plate (103) that generates sound, a body (102) that provides a space for the reed plate (103), an upper cover (101) that covers the upper part of the body (102), and a lower cover that covers the lower part of the body (102). The above reed plate (103) is the part that produces sound in a harmonica and is mainly made of a metal such as brass or stainless steel. Th
