Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like figure 1 As shown, the speaker module includes a peripheral frame and a speaker unit housed inside the peripheral frame, wherein the peripheral frame includes a first housing 11 and a second housing 12; the speaker unit includes a magnetic guide plate 25, and the magnetic guide plate 25 Other than the speaker unit 20 (only briefly shown in the figure). Wherein the first casing 11 accommodates and fixes the loudspeaker unit, the first housing 11 is provided with a storage groove 111 formed by removing material at the position facing the magnetic guide plate 25 of the loudspeaker unit, and the magnetic guide plate 25 is embedded in the storage groove 111, It is beneficial to reduce the height of the product. The second casing 12 is provided with a sound outlet 121 at the position facing the speaker unit, and two cavities a...

Abstract

The invention discloses a speaker module which comprises a speaker single body and an outskirt frame containing and fixing the speaker single body. The speaker single body comprises a vibrating film. A sound outlet is arranged in a position, directly opposite to the vibrating film, of the outskirt frame. A rear sound cavity is enclosed by the speaker single body and the outskirt frame. An opened end which communicates the rear sound cavity and the outside is arranged in an end face of one side, corresponding to the rear sound cavity, of the outskirt frame. The electronic device of a terminal is combined with the opened end to seal the rear sound cavity. The invention discloses an electronic device, a combination plate is included in the electronic device. The combination plate and the opened end of the speaker module is combined to seal the rear sound cavity. A space of the speaker module is fully used with such a structure. Under the condition that the size of the speaker module is limited, a space of the rear sound cavity of the speaker is enlarged, the acoustic performance of the speaker module is ensured and an internal structure of the electronic device is fully used.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to a loudspeaker module and an electronic device using the loudspeaker module. Background technique [0002] In the prior art, the speaker module includes a speaker unit and a peripheral frame for accommodating and fixing the speaker unit. For a speaker module that emits sound from the front, the sound outlet is arranged on the side of the peripheral frame facing the diaphragm of the speaker unit. The speaker module has a rear acoustic cavity, which is formed by the speaker unit and the peripheral frame on the side of the diaphragm away from the sound outlet. The rear acoustic cavity of the speaker module needs to be sealed and has a certain volume to ensure the low frequency of the speaker module. sound effects. [0003] However, with the development trend of thinner electronic devices (such as mobile phones, computers, etc.), the space reserved for the speaker module in the electr...
