Abstract:
In the specification and drawing a display module is disclosed. The display module comprises a backboard, a display component and a printed circuit board with at least one locating pin formed thereon. The backboard has at least one locating hole. The display component is disposed on the backboard. The at least one the locating pin is inserted in the locating hole. Moreover, a method for manufacturing the printed circuit board and a method for fabricating the display module are also disclosed in the specification and drawing.
Abstract:
The present invention provides an automatic tone-following method and system for music accompanying devices, which detects the frequency of the singer's voice instantly and continuously and compares it with the theme tone frequency of the accompanying music to estimate the error between the tones of the singer and the music so as to adjust the tone of the music to match the tone of the singer's voice. The present invention calculates the fundamental frequency of the user's voice every short section of time through a tone estimator, then converts the fundamental frequency of the user's voice into user scale sequence in a scale sequence recorder, then compares the difference between the user scale sequence and the theme scale sequence through a scale matcher. Whether a transposition is needed through a transposition judger is determined so that the scale parameter in the music synthesizer can be adjusted.
Abstract:
A method for keying human voice audio frequency includes the steps of setting the human factor of the singer; recording the singing of the singer; calculating the audio frequency by an audio frequency counter; recording the maximum ground frequency by the recorder; estimating a maximum fundamental audio frequency thereof by the diapason estimator; and converting the maximum fundamental audio frequency into musical terminology, the best audio frequency of the singer being determined. The method for keying human voice audio frequency is very easy and fast.
Abstract:
A supporting mechanism of a backlight module includes a first member, a second member, and a connector connecting the first and second members. The first member has an initial thickness and the second member also has an initial thickness. The initial thickness of the first member is greater than that of the second member and the first member is longer than the second member.
Abstract:
A backlight module includes a substrate and at least a lamp. The substrate includes a high-voltage side, a low-voltage side and a bottom surface linking therebetween. The lamp includes two electrode ends respectively connecting to the high-voltage side and the low-voltage side. The lamp and the bottom surface form an acute angle to reduce leakage current percentage. A display includes the backlight module.
Abstract:
A backlight module and wire mount assembly used therein. The assembly includes a base and a wire mount. The base includes a surface and a protrusion formed on the surface. A through hole is formed between the protrusion and the surface. The wire mount is disposed on the surface of the base in a manner such that it passes through the through hole. The wire mount serves to fix the wire.
