Problems solved by technology

However, due to the reduction of the vibrating surface of the vibrating body, the final sound quality is not good
In the prior art, there are also speaker units that support multiple piezoelectric elements in the form of cantilever beams and connect the vibrating end to the edge of the vibrating body. Although such a structural setting can obtain a high overall sound pressure level and no sharp peaks frequency characteristics, but the structure supported by a cantilever beam will increase the production cost

Embodiment Construction

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the speaker unit 1 of the present invention includes a bracket 10 , a vibrating body 20 and a vibrating device 30 . The bracket 10 is a supporting component supporting the vibrating body 20, which is made of metal, resin and other materials, and is formed into a cylindrical shape with a certain thickness. The inner side of the bracket 10 is fixed with the end of the vibrating body 20, so the vibrating body 20 can be supported by the bracket 10 to realize vibration. , In addition, a cylindrical shape with a bottom surface can also be adopted.

[0019] The vibrating body 20 can use a sheet-like member, and emits sound through vibration. It is made of a moderately elastic material such as metal or resin and has a round shape. The metal material can be phosphor bronze, stainless steel, magnesium, aluminum, t...

Abstract

The invention brings forward a loudspeaker unit. The loudspeaker unit comprises a support, a vibrating body, a vibration apparatus and a control portion, wherein the end of the vibrating body is fixed at the inner side of the support, at least one opening is arranged at a position, which is deviated from the center of the vibrating body, in the vibrating body, the vibration apparatus is assembled on the vibrating body, the control portion is used for processing externally input signals and generating driving signals so as to drive the vibration apparatus, and the control portion comprises a processing portion, a DA converter and an amplifier which are successively connected. The loudspeaker unit related to by the invention can generate many minimal vibration modes and can enable frequency features to become relaxed and natural, thereby enabling output timbre to be good.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to a loudspeaker unit that converts electrical signals into physical vibrations to generate sound. Background technique [0002] The speaker unit refers to a device that first increases the amplitude of the electric wave that records the sound, then transmits it to the vibrating device and causes the vibrating body to vibrate, thereby generating sound waves (also called sound) within the audible range. In speaker units in the prior art, permanent magnets and voice coils are frequently used as vibration devices. A loudspeaker having such a structure often requires a large number of parts, and thus tends to be large and heavy. [0003] In recent years, as the use of small portable terminals such as mobile phones has become more and more popular, the miniaturization and weight reduction of speaker units have also become people's demands. Therefore, manufacturers began to use piezoelec...
