Problems solved by technology

[0003] However, in traditional electro-acoustic devices, most of the passive radiators are fixed inside the shell of the electro-acoustic device. Therefore, when the traditional electro-acoustic device leaves the factory, the low-frequency resonance of the output sound has been determined. Frequency, so it is difficult for the user or the original factory to simply adjust the characteristics of the appropriate output sound according to the preferences and needs of individual users, which is a hindrance to the current trend of emphasizing product individuation

Embodiment Construction

[0026] In order to allow those skilled in the art to better understand the electro-acoustic device, the following description is as follows in conjunction with the first embodiment and accompanying drawings, please refer to Figure 1 to Figure 6 . The electro-acoustic device may be, for example, a sound box, a headphone, an earphone or other types of electro-acoustic devices. Here, a headphone is taken as an example, and for the convenience of description, this embodiment is based on a single 20 The direction of the output sound is upward as a reference.

[0027] The main components of the electro-acoustic device 1 of this embodiment include a housing 10, a monomer 20 and a passive radiator 30, and the structures of the components and the relationship between them are described in detail as follows:

[0028] Please refer first Figure 1 to Figure 3 , The casing 10 includes a first outer cover 11 , a first ring member 12 , a second ring member 13 and a second outer cover 14 f...

Abstract

The invention relates to an electric-acoustic device with a movable passive radiator. The electric-acoustic device comprises a shell, a single body arranged in the shell and the passive radiator. The shell is provided with a slot and a first sound hole. The single body and the shell commonly define a front cavity facing the first sound hole and a back cavity opposite to the front cavity. The passive radiator is movably arranged in the back cavity in the shell. By means of the design of a specific structure, the passive radiator can be movably adjusted towards the single body or away from the single body, or the passive radiator moves between an inserting position in the back cavity and a departing position outside the back cavity through the slot. Thus, a user or an original factory can easily adjust the position of the movable radiator, or the passive radiator is moved to the departing position from the original inserting position so that the passive radiator or parts in the passive radiator can be replaced, and the whole replacing process is relatively simple and convenient to conduct.

Description

technical field [0001] The present invention is related to the loudspeaker defined by the international classification number H04R, and specifically refers to a loudspeaker, which can be conveniently adjusted or replaced with a passive radiator arranged inside the loudspeaker. Background technique [0002] Passive radiators are also called passive diaphragms, which are usually set together with the monomer in the speaker of an electro-acoustic device such as an audio system, and allow the monomer and the passive diaphragm to share the back cavity. When the monomer emits sound, the air compressed by the monomer in the back cavity will be transmitted to the passive diaphragm, and then indirectly drive the passive diaphragm to produce sound. Therefore, for an electro-acoustic device with a small back cavity volume, with the help of counterweights of different weights in the passive diaphragm, the low-frequency resonance frequency of the output sound can be submerged and the res...
