Embodiment Construction

[0023] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

[0024] In order to solve the problem that the independent cavity structure of the current loudspeaker diaphragm has too much adjustment force on FR, which leads to deep troughs in the high-frequency resonance peak, making the FR high-frequency curve not flat enough, etc., the present invention provides a speaker module, The independent cavity of the speaker module is connected to the front acoustic cavity through the communication channel, and a damping structure is set in the communication channel, and the acoustic damping of the communication channel is adj...

Abstract

The invention provides a loudspeaker module and an electronic device. The loudspeaker module comprises a first shell, a second shell forming an accommodating space with the first shell, and a loudspeaker monomer arranged in the accommodating space. A diaphragm of the loudspeaker monomer divides the accommodating space into a front vocal cavity and a rear vocal cavity. An independent cavity is arranged in the accommodating space. The independent cavity is communicated with the front vocal cavity through a communication channel. A damping structure is arranged in the communication channel. Acoustic damping of the communicating channel can be changed through a damping structure, and it is ensured that the FR high-frequency curve of the product is flat and the performance is stable.

Description

technical field [0001] The present invention relates to the field of acoustic technology, and more specifically, to a loudspeaker module and an electronic device provided with the loudspeaker module. Background technique [0002] In recent years, the expansion of the consumer electronics market has led to the widespread use of a large number of mobile phones and notebook computers. As an important acoustic component in consumer electronics products, there is also a wide demand for sound emitting devices. With the requirement of thinner and lighter appearance and more excellent performance of consumer electronic products, the sound generating device, as an important component of such products, has also put forward higher and higher requirements in terms of performance, size, safety, etc. . [0003] At present, the loudspeaker module used as a sound generating device usually adopts an independent cavity connected to the front acoustic cavity to adjust the FR high-frequency re...
