V. Creation Instructions (1) The technical field to which the new type belongs: The creation is to provide a kind of special type that can enhance the speaker's porcelain or synthesized sounds to be output. > Previous technology of Jiesheng: According to 'Knowledge of the evolution of the structure of the microphone using the larynx cavity, such as Taiwan ’s public health f contact ink microphones' patent d: 'When the spring receives sound waves', the reason is: Into a stone, causing a wave of true waves. Announcement No. 4 4 4 created by the creator "improved the acoustic wave material, the material of the wave" makes its sound wave output signal lose the sound wave transmission and sound response frequency; the original 4 6 2 5 7 5 "Laryngeal cavity vibrating microphone case" which enlarges the foam area and increases the response frequency of vibration sound waves. No. 09 2 1 5 7 9 7 (public "improved structure of laryngeal cavity vibrating microphone" "Invention" is (60) above the circuit board (50), the flexible partition (60) is in the upper cover (20) and its circular groove (22) C6 2), and the sound energy is used in the cavity 6 The pressure of the film is a real-type electric microphone to reduce nasal sounds, especially the pressure of 3 10 1 is transmitted by spring input. The output of 9 9 8 is to reduce the inventor ’s accuracy by using the authenticity rate. Notice No. 4 6 Patent case 'Surface-mounted outer periphery (Slot wall' 2) Resonant electric microphone, No. 1 "Skin is a guided wave material sound wave, as the sound wave will lose" Ceramic piezoelectric bubble body made To guide the sound, to promote the announcement of a good structure for the invention of foaming inventions "The patent room has two floors, 2 No. 5 7 5) The author created a flexible partition 61) which is tightly connected to form a cavity.

M241925 V. Creation instructions (2) The amplitude of the case (50) The indirect rate of the case (50) How to make the cavity ring so that the metal piezo will resonate the sound The new internal creation microphone, and by the way, set a response to Will be up to reach the radio. Please refer to the inside with grooves 2 2 above 3〇; circuit board strong effect, although it is a practical upper surface, the piece that acts on the piezoelectric should directly receive waves and convert to capacitance: the main purpose is to connect with the skin The speaker at the above empty resonance frequency can listen to the circular grooves 1 2 and 2 2 in FIG. 1 and 2 so that the surface of a meter 40 of 50 is plated with a chip 4 0 — of which at least one The body is embedded to fix the piezoelectric sheet 40 on the vertical distribution 6 3, 6 4 to provide sound wave transmission without distortion. 'However, the flexible diaphragm (60) is provided on the ceramic film of the resonant frequency plate (40) generated by the circuit, which also refers to the cavity (62). Therefore, if the frequency resonates, it directly acts on the ceramic film and reaches the acoustic wave. The amplitude of the resonance so that it can be output. By providing a cavity with a piezoelectric contact of a ceramic thin film and a ceramic thin film cavity of a piezoelectric sheet, the sound wave which is enhanced by the sound wave received in the cavity directly acts on the ceramic film until the speaker becomes true and not Distorted sound indication 'This creation includes: Among them, the cover 10 can be connected to a circular concave bottom 盍 1 〇 and the upper cover 2 〇 to form a body surface attached to a metal piezoelectric sheet 40, laminated ceramic The thin film 4 2 ′ circuit board 50 is located in the receiving groove 32 inside the main body 30; in the space between the bottom plate 10 and the bottom cover 10, a hollow tube 60 is provided to form a plurality of empty spaces 6.

Page 6 M241925 V. Creation instructions (3) The lower end of the hollow tube 60 can be connected to a piece of body 65; the bottom cover 10 is provided with a perforation 1 1 on the surface, and the hollow tube 60 can shuttle straight into the perforation 1 1 The sheet body 65 can be connected to the surface of the bottom cover 10. As shown in Figures 3 and 4, the bottom surface of the sheet body 6 5 is connected to three hollow tubes 60, the bottom cover 10 is provided with three perforations 11 on the surface, and the three hollow tubes 60 can be shuttled straight into the three perforations 11 , To form a larger number of cavities 61, 62, 63, 64. As shown in Figures 5 and 6, a small perforation 13 is provided on the connecting portion of the bottom cover 10 and the hollow tube 60. As shown in FIG. 1, a flexible spacer 70 is attached to the surface of the circuit board 50, so that another cavity 72 is formed between the flexible spacer 70 and the upper cover 20. As shown in Figure 7, the hollow tube 60 in this creation can also be implemented in solid form. Embodiments: (1). As shown in FIG. 2, the sheet body 65 is attached to the skin 90 of the speaker's neck or face at an appropriate position in the bottom cover. The space between the 10 and the piezoelectric sheet 40 Two large and small cavities 6 1 and 6 2 are formed each. When the human larynx cavity vibrates (source of sound wave vibration), the contact surface 1 5 transmits the vibration sound waves to the plurality of cavities 6 1, 6 2. The function of the cavities 6 1 and 62 is to combine the sound wave energy in each of the cavities 6 1 and 62 to form a resonance space to generate a resonance frequency. The principle is the same as that of Homz (Η EL Μ Η〇). LTZ) cavity resonator. According to the difference in the shape of the cavities 6 1 and 6 2, the amplitude enhancement effect can be generated for different frequencies, such as percussion instruments (such as drums).

M241925 V. Creation instructions (4) Therefore, the use of sound response can be used to make the surface of film 40 in this case more direct from 4 2 so that the sound machine number can be confirmed. As shown in Figure 3 (2), the number of sound sources that can be increased in each complex cavity is shown in Figure 2. Piezo sheet 4 0 7 0, the frequency response wave energy made by soft 7 2 effectively lifts the ceramic cavity of tube 6 Cavity 6 The piezoelectric sheet is converted into a step-by-step receiver, and the 3rd, 6th, and 6th sound waves generated by cavity 6. The cavity and the circuit spacer should be raised in the cavity. 0 its bottom film 4 1, 6 4 0 more The speaker of the electric energy wave shows that the number of resonance transmission of the number 4 and number 6 is 6 1. The plate 5 0 7 0 forms a common one, and the end can be connected to the 2 and 2. The supply of sound to the fixture increases 2. Frequency distortion 6 At 2 o'clock, the vibration frequency is transmitted, and its real sound in 6 2 corresponds to or directly 'resonates the pronunciation, and the number of voices of the more accurate speaker is increased when the resonance wheel is received', making the pronunciation 6 3, 6 more (ie, the lower the rate The resonance vibration also transmits the vibration wave rate, and the vibration of the contact source with the resonance sound is used for the vibration of the ceramic frequency. The vibration of the air source is much clearer. Especially the electric sound wave porcelain thin cymbal sound wave, the distortion is clear and true cavity 6 1 dynamic sound wave response, air strength), dynamic sound Acting on the handed soft septum and reinforcing the south and bass in another cavity, as shown in Figures 5 and 6, in order to improve the sound of the sound source, the vibration sound waves can be more directly and widely entered into the cavities 6 1 and 6 2. A small perforation 1 3 is provided on the surface of the bottom cover 丄, whereby the surface of the bottom cover i 〇 can directly contact the skin 90, and the vibration sound of the sound source can directly enter the cavity 6 1 through the small perforation 1 3 The resonance response of the sound wave is done in 6 and 6. As shown in Figure 7, when this work is to obtain a higher frequency response
