Embodiment 1

[0010] In Embodiment 1, the automatic voice-changing earphone is used to simply realize the simple voice-changing function. Specifically speaking, an earphone is characterized in that it also includes a position switch. When the earphone is at the level, the position switch connects a resistance, and the resistance is connected in parallel to the sound energy conversion device of the earphone. The sound energy conversion device It can be the coil of the speaker, and the piezoelectric ceramic of the sound energy conversion device. When the resistance is connected in parallel to the sound energy conversion device, the output impedance of the audio circuit will drop, resulting in the input power of the sound energy conversion device drop, so that the earphone realizes the voice changing function. The output impedance of the audio circuit drops, and the resistance value of the specific parallel resistor corresponding to the power drop can be calculated through the impedance formul...

Embodiment 2

[0011] Embodiment 2, it is possible to realize the sound changing function of the earphone by improving that the position switch is a mercury switch.

Embodiment 3

[0012] Embodiment 3, the sound changing function can be realized by improving the position switch to a gravity switch. The specific method is to have a metal ball in an insulated conical container, and on the wall of the insulated conical container Two metal contacts are provided, and the two metal contacts are located at both ends of a diameter of the tangent circle on the wall of the insulated conical container, when the insulated conical container When the central axis is vertical and the opening is upward, the tapered tip part of the insulating tapered container, at this time, the metal ball is in contact with the two metal contacts provided on the wall of the insulating tapered container , the metal ball falls into the tangent circle plane lower than the center of the metal ball, causing the position switch to be turned on.

Abstract

The invention discloses a method for manufacturing an intelligent earphone, and a sound change earphone is adopted to realize a simple sound change function. Specifically speaking, the method for manufacturing an intelligent earphone includes a position switch, when the earphone is horizontal, the position switch is connected with a resistor, the resistor is connected with a sound energy conversion device in parallel, the sound energy conversion device may be a coil of a loudspeaker and adopts piezoelectric ceramic, and when the resistor is connected with the sound energy conversion device in parallel, an output impedance drop of a sound box circuit causes an input power drop of the sound energy conversion device, thereby realizing the sound change function of the earphone. The output impedance of the sound box circuit drops, and a resistance value of the specific parallel resistor corresponding to the power drop can be calculated through an impedance formula. According to variations of the invention, a mercury switch or gravity switch can also be used to realize a sound change function.

Description

technical field [0001] The invention relates to the field of electronic audio, in particular to an earphone, in particular to a manufacturing method of an intelligent voice-changing earphone. Background technique [0002] In the field of electronic audio in the world today, earphones are a common device. Generally speaking, earphones do not have the intelligent function of automatic voice change. Simultaneously in the field of electronic audio, especially in the digital audio technology, automatic voice changing intelligent technology has occurred. Generally speaking, it needs the support of computer software, and some are designed in the form of hardware, but the prior art is quite complicated relatively speaking. Contents of the invention [0003] The technical problem of the present invention is that a simple method is needed to realize some simple intelligent voice changes. For example, when people are standing or sitting, they need a higher volume, but when they are...
