Description
Technical Field
The invention relates to the technical field of vibrating piece vibration, in particular to a novel vibrating piece technology capable of improving the vibrating effect and amplitude of a vibrating diaphragm of an earphone and a novel headphone structure, and particularly relates to a dual-resonance earphone vibrating piece unit and an earphone with the structure.
Background
It is known that earphones function to receive electrical signals from a media player or receiver and convert them to audible sound waves using a speaker proximate to the ear. From the industry, cell phone headsets are classified into two standards: the OMTP standard is usually called the national standard and CTIA is called the international standard. Different standards also have different requirements for headset production.
From different bases of classification, the earphones can be classified into various categories, such as: earphones are classified according to their transduction mode, mainly including: a moving coil system, a moving iron system, an electrostatic system, and an equivalent magnetic system. Structurally, functional methods are classified into a semi-open type and a closed type. Ear plugs, ear hooks, ear insertion and head are classified from wearing forms; single earphones and multi-earphone are classified according to the number of people wearing the earphone. The earphone is distinguished from a sound source and can be divided into an active earphone and a passive earphone; active headsets are also often referred to as paddle-card headsets. Regardless of the type of wired earphone, the structure composition and the working principle of the wired earphone are similar to those of a loudspeaker, and the wired earphone is also composed of a magnetic circuit system and a sounding system. For example, a conventional headset is mainly composed of four parts: the head band, control sound production unit, ear muff and lead wire.
The headband has the function of fixing the left and right sounding units and placing the sounding units on two sides of the head, and the structure of the headband and the connection mode of the headband and the sounding units determine the pressure of the headband and the earmuffs on the head, so that the wearing comfort of the earphones is influenced. The ear muff is the part of the head contacting with the sound producing unit, and is very important for the moving coil earphone, and the function of the ear muff is to reflect the low frequency back and ensure the reproduction of the low frequency. The lead of the earphone is a connecting wire between the output end of the earphone amplifying circuit and the voice coil of the earphone. The sound production unit of the earphone is the most important part of the whole earphone, and mainly comprises a magnetic circuit system, a vibration system, a cavity, a hole and other acoustic structures.
The sound generating unit of the earphone can generate different sounds, the working principle of the earphone is similar to that of a loudspeaker, and the following websites are as follows: the website of https:// www.sohu.com/a/216178295_121611 describes the sound production principle of the type of a moving coil unit, the specific principle is as shown in fig. 1, a vibrating diaphragm of the moving coil unit is attached with a coil, and a changing current generates an electric field through the coil to act with a permanent magnet below, so that the vibrating diaphragm vibrates and produces sound.
It can be seen from above-mentioned prior art that, the key structure of earphone sound production is the vibrating diaphragm structure, and its vibrating diaphragm unit (also known as vibrating diaphragm unit, specifically name according to the vibrating diaphragm structure of different grade type) because the restriction of vibrating diaphragm structure at traditional earphone during operation for the vibration region of its diaphragm only maintains at middle part region, this vibration range that just makes whole vibrating diaphragm structure receives very big restriction, when using under some occasions to fidelity requirement is higher, the unable accurate expression of bass and high pitch of earphone usually, thereby influence the sound production effect of earphone.
For example, patent documents of prior application No. CN202010660144.5 of this company disclose a patent name: the structure of the vibrating earphone of the vibrating assembly and vibration type earphone with the vibrating assembly, its main structure includes a sound conduction body with mesh on the surface, the middle part of the shell cavity of the sound conduction body with mesh on the surface is fixedly provided with a sound membrane component, the shell cavity of the two sides of the sound membrane component is respectively and symmetrically provided with a polar plate component which is symmetrically arranged relative to the central plane of the shell cavity, the interval distance between the two polar plate components is adjustable, the two polar plate components are respectively connected with a booster transformer equivalent circuit through leads, the input end of the booster transformer equivalent circuit is connected with an external audio input signal, the sound membrane component is connected with external high voltage through leads, and high voltage is formed between the sound membrane component and the output end of the booster transformer equivalent circuit.
It can be seen from the disclosure that, in the above-mentioned prior patent application, mainly through the adjustable vibration assembly, a more real sound reduction can be obtained, and this way can improve the problem of vibration limitation of the vibrating plate to a certain extent, but it has a limitation in terms of the effect of enhancing the amplitude and the width of vibration of the vibrating plate because the actual effect of changing the edge vibration of the vibrating plate cannot be achieved.
Therefore, the problem of earphone sound production distortion caused by insufficient vibration of the vibrating diaphragm or the vibrating piece in the prior art is researched, and a double-vibration-resonance-type earphone vibrating piece unit is researched and designed to better guarantee the sound production effect and better solve the problem in the prior art.
