Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Referring to fig. 1 and fig. 2, an electronic device according to an embodiment of the present invention is shown, which may specifically include the following structure:
an electroacoustic device 10 and a middle frame 20;
the middle frame 20 is provided with a sound guide groove 21, the back cover of the electroacoustic device 10 is fixedly connected with the sound guide groove 21, the sound guide groove 21 is communicated with the cavity 22 inside the middle frame 20 to form the back cavity 11 of the electroacoustic device 10, and the electroacoustic device 10 is used for converting an electric signal into an acoustic signal.
Specifically, as shown in fig. 1, the electronic apparatus includes an electroacoustic device 10 and a center frame 20, and the center frame 20 is provided with a sound guide groove 21. As shown in fig. 2, the frame body of the middle frame 20 has a hollow structure, and the hollow structure forms a cavity 22 inside the middle frame 20. The electroacoustic device 10 is used to convert electrical signals into acoustic signals, such as: a receiver, a speaker, etc., and in general, a processor may be included in the electronic device, the processor is electrically connected to the electroacoustic device 10, the processor transmits an electrical signal to the electroacoustic device 10, and the electroacoustic device 10 receives the electrical signal and converts the electrical signal into an acoustic signal to realize the conversion of the electroacoustic signal. The middle frame 20 is used as a supporting structure of the electronic device, the sound guiding groove 21 is disposed on a side wall of the middle frame 20, and may be integrated with the middle frame 20, or may be connected to the middle frame 20 by bonding, and the like, wherein an opening is disposed on the side wall of the middle frame 20 connected to the sound guiding groove 21, so that the sound guiding groove 21 communicates with the cavity 22 inside the middle frame 20, as shown in fig. 2.
The rear cover of the electroacoustic device 10 is fixedly connected to the sound guiding groove 21, for example, by bonding, clamping, etc., as shown in fig. 2, the electroacoustic device 10, the sound guiding groove 21 and the middle frame 20 form a closed cavity structure, that is, the rear cavity 11 of the electroacoustic device 10 is formed. Because the front cavity of the electroacoustic device 10 mainly transmits medium-high frequency signals and partial low frequency signals, and the rear cavity 11 mainly transmits low frequency signals, the output frequency response curve of the electroacoustic device 10 can be adjusted to a certain extent by changing the parameters of the volume size, the air permeability and the like of the rear cavity 11 of the electroacoustic device 10, so that the low frequency sound of the electroacoustic device is prevented from being short-circuited, the low frequency effect of the electroacoustic device 10 is improved, and the tone quality of the electroacoustic device 10 can be effectively improved. In particular, for different diameter electroacoustic devices, there are differences in the size of the back volume.

When the effective volume of the rear cavity is 0.8cm3When f is present0The attenuation is about 400Hz to 450 Hz. When the volume of the rear cavity is 1cm3When f is present0The attenuation is about 300Hz to 350 Hz. When the effective volume of the back cavity is 1.5cm3When f is present0The attenuation is about 250Hz to 300 Hz. When the effective volume of the back cavity is 3.5cm3When f is present0The attenuation is about 100Hz to 150 Hz. Thus, for a 13mm diameter speaker, the low frequency performance is better (e.g., f)0At around 800 Hz), the effective volume of the rear chamber should be greater than 0.8cm3. When low frequency performance is poor (e.g., f)0Greater than 1000Hz), the effective volume of the rear chamber should be greater than 1cm3. Therefore, the effective volume of the back cavity of a 13mm diameter speaker is preferably 1.5cm3When the effective volume of the back cavity is more than 3.5cm3The volume change has a small effect on the low frequency performance.
