However, reducing the size of a mobile phone must involve the performance of the speaker module. For example, the volume of the speaker module of the speaker module is closely related to the quality of the output sound. will seriously affect the bass sound
Generally speaking, even through various attempts, the bass sound effect can only reach 600Hz, and it cannot show the bass sound effect below 600Hz, and cannot satisfy the user's auditory experience.
[0003] Especially in the case of tablet computers, the thickness of the body has a certain size limit, which further limits the design conditions of the speaker and its sound box

Embodiment Construction

[0035] figure 1 is a front view of a portable electronic device according to an embodiment of the present invention. figure 2 It is a flow chart of the design method of the extension system of the subwoofer of the present invention. Please also refer to figure 1 and figure 2 , in the present embodiment, the design method of the extension system of the subwoofer is suitable for portable electronic devices. Here, taking a tablet computer as an example, it has a body 10 and a speaker module arranged therein, including an extension of the subwoofer. System 100, left channel speaker system 200L and right channel speaker system 200R. Here, the left-channel speaker system 200L and the right-channel speaker system 200R are as known in the prior art, and they are used to process mid- and high-frequency sounds, so details are not repeated here.

[0036] In this embodiment, for figure 1 The tablet computer shown can still successfully configure the subwoofer in the body 10 , so it...

Abstract

The invention provides an extension system of a bass loudspeaker applied to a portable electronic device which comprises a bass loudspeaker, a front sound box and a rear sound box, the bass loudspeaker. The front sound box and the rear sound box are respectively arranged in a body of the portable electronic device, the rear sound box is a closed space, the volume of the front sound box is larger than that of the rear sound box, and loudspeaking holes are formed in the surface of the body of the portable electronic device by the front sound box. The invention also discloses a design method of the extension system of the bass loudspeaker.

Description

technical field [0001] The invention relates to an expansion system of a subwoofer and a design method thereof. Background technique [0002] Micro-speakers are widely used, and many portable electronic devices are equipped with speakers to play music or sound effects. However, in order to meet the user's requirement for the convenience of carrying the electronic device, the electronic device is becoming thinner, and the internal speaker must also be thinner. However, reducing the size of a mobile phone must involve the performance of the speaker module. For example, the volume of the speaker module of the speaker module is closely related to the quality of the output sound. It will seriously affect the bass sound. Generally speaking, even through various attempts, the bass sound effect can only reach 600 Hz, and the bass sound effect below 600 Hz cannot be displayed, thus failing to satisfy the user's hearing experience. [0003] Especially for a tablet computer, the thi...
